10 Ways To Increase Your Electric Vehicle’s Range

vuyi on March 20, 2023

As uneasy as it may be to drive a fuel powered vehicle nearing empty, it is even more worrisome to drive with one eye on the state-of-charge gauge of an electric vehicle; hoping to reach the nearest charging station.

Though some of the latest electric vehicles (EVs), can run for more than 400kms on a single charge, range anxiety remains a common consideration for many owners of electric vehicles.

Thankfully, it is possible to drive further on one charge and add a few more kilometres to your drive with these easy and realistic adjustments to your driving pattern.

Drive Smoothly

Simply put, ‘driving like you stole it’, drains your EV’s battery at an accelerated rate. As tempting as it is to leverage an EV’s instantaneous torque for quick take offs, it’s more prudent to take it easy when accelerating from a standing start.

2. Slow Down

Try to keep your speed at or under 60km/ph whenever possible. You’ll not only avoid getting a speeding ticket, but you’ll bolster your battery range in the process. Engage the “Eco” mode of your EV for gentler acceleration and general driving. Of course, if you EV has “Sport” mode, you’ll have to keep that switched off until you have recharged and are ready for a more lively drive.

3. Maximize Regenerative Braking

Whenever possible, leverage your EV’s energy-recovering regenerative braking function as you come to a stop, and use the brakes only when necessary. Enable your car’s maximum regenerative setting to send extra power back to the vehicle’s batteries while decelerating.

4. Go Easy On The Heat

Running an EV’s heater, especially at full blast, puts a big drain on battery power. In cooler temperatures, dial down the climate control and rather rely on the heated seats and heated steering wheel (if your vehicle is equipped with these creature comforts) to keep things cozy.

5. Be Cool With The AC

Likewise, operating the air conditioning consumes battery power at a quick rate. Try running only the fan, and not the compressor whenever possible; driving with the windows open is an obvious alternative. Unfortunately, the latter will take a toll on your vehicle’s aerodynamics at higher speeds and, in turn, reduce its operating range slightly. That’s because the more aerodynamic “drag” that’s placed on a vehicle, the more energy it takes to run it, especially at higher speeds. Still, operating the AC at full chill will drain the battery far quicker than will driving with the windows down. Again, pre-cool the car in summer months while it’s charging to help reduce the need to run the AC once you hit the road.

6. Tend To The Tyres

Sources suggest that over 25% of all vehicles on the road have improperly inflated tires. As with a conventional vehicle, driving an EV with under-inflated tyres will not only increase its energy consumption, but can lead to uneven and/or premature tread wear. Check the air pressure frequently using a simple tyre gauge, as it can vary by an average of one PSI (pound per square inch) with every 10-degree (Celsius) change in air temperature. Have the tyres properly inflated according to the PSI recommended by the automaker. This information is usually noted on a sticker that’s affixed to the driver’s side door frame or within the fuel cap.

7. Travel Light

As any automotive engineer will tell you, reducing a vehicle’s weight is the easiest way to boost its efficiency. To that end, get the junk out of the trunk, as carrying an additional 45kg of luggage can increase a vehicle’s energy consumption by 1-2% percent.

8. Keep It Slick

Avoid installing exterior accessories like roof racks and cargo carriers on your EV. Again, the aforementioned aerodynamic drag such items create will cause added energy consumption at higher speeds.

9. Plan A More-Efficient Route

It may take less time to get to a given destination by driving on the highway, but you can help maximize your car’s operating range by opting to choose a route that allows you to drive steadily at lower speeds. Avoid high traffic areas, steep gradients and hilly or mountainous areas whenever possible. If your EV has a navigation system that can suggest energy-efficient routes, be sure to use it.

10. Time Your Charge

You may not want to keep your car plugged into its charger whenever it’s in the garage. That’s because most EV batteries will slowly self-discharge when they’ve finished charging. You may be able to recover a few extra miles of range by timing the charge so the battery pack is at full strength just before you hit the road. This can also be advantageous to the battery’s long-term health.

Carbon is Our Enemy: Let’s Use Everything We’ve Got to Fight It!

vuyi on July 28, 2021

By Dr. Gill Pratt: Chief Executive Officer of Toyota Research Institute (TRI) and an Executive Fellow of Toyota Motor Corporation, shares his thoughts on the necessity of hybrids and plug-in to maximise our limited battery supply and reduce carbon.

I love electrified vehicles. I love them not only because I’ve worked on their development for decades, but because I’ve been deeply concerned about greenhouse gases and climate change since I first learned about them from my father, who worked for the Air Pollution Control division of the New Jersey Department of Environmental Protection.

Today, I live with my family in California, and like my neighbors last year, we watched the sky turn orange with smoke due to extensive wildfires. On the opposite side of the spectrum, we now see unprecedented floods in Europe. Regardless of how much of today’s extreme weather events are directly attributable to climate change, I feel passionately that to prevent even worse catastrophes, we must achieve carbon neutrality, and soon.

Today, besides owning a Toyota Sienna Hybrid Electric Vehicle (HEV) and RAV4 Prime Plug-In Hybrid Electric Vehicle (PHEV), I also own a Tesla model X Battery Electric Vehicle (BEV). I love them all.

In line with my concerns, starting in the late 1980s as a graduate student, research scientist, and faculty member at MIT, I designed power electronics that helped MIT’s solar-electric vehicle team win races around the world. Later I helped our team captain, James Worden, create Solectria Corporation, which made electric vehicle components, early electric vehicles and photovoltaic inverters.

Today, besides owning a Toyota Sienna Hybrid Electric Vehicle (HEV) and RAV4 Prime Plug-In Hybrid Electric Vehicle (PHEV), I also own a Tesla model X Battery Electric Vehicle (BEV). I love them all.

You would think that with all my experience, I would be an enthusiastic proponent of ditching the Internal Combustion Engine (ICE) and switching as soon as possible to pure Battery Electric Vehicles (BEVs). I am not.

Following Science

As a scientist, I know that as with many other natural and man-made systems, a diversity of EV drivetrain types is a better way to prevent climate change than a monoculture of only BEVs. Why is this? For two reasons: First, producing a battery cell costs money, uses natural resources, and produces significant greenhouse gases.

I love my Tesla Model X BEV. But commuting 30 miles in it every day — the average US commute — and recharging it every night is wasteful of the carbon reducing potential of most of its over 300-mile (482km) range battery.

Sometimes we take the Tesla on long trips. But most of the time, 90% of its battery cells aren’t doing any good, and would reduce carbon much more if they were harder at work in other types of electrified vehicles, including HEVs or PHEVs.

For example, we hardly ever put gas into our RAV4 Prime PHEV, which has a battery ⅙ as large as our Model X BEV
– Dr. Gill Pratt: Chief Executive Officer of Toyota Research Institute (TRI) and an Executive Fellow of Toyota Motor Corporation

Maximizing the benefit of every battery cell produced requires that we distribute them smartly.

This means putting them into a greater number of “right sized” electrified vehicles, including HEVs and PHEVs, instead of placing them all into a fewer number of long-range BEVs, like my model X. This is particularly important because presently it is difficult to recycle the kinds of batteries used in BEVs. If we are to achieve carbon neutrality, we must pay attention to all parts of the “3R” process — Reduce, Reuse, and Recycle.

For example, we hardly ever put gas into our RAV4 Prime PHEV, which has a battery ⅙ as large as our Model X BEV. For the same investment in batteries as our single Model X, five other RAV4 Prime customers could reduce their carbon footprint too.

Don’t I think we should try to increase battery production, lower the carbon footprint of electric power plants, and expand rapid charging stations as quickly as possible? Of course I do.
– DR. GILL PRATT: CHIEF EXECUTIVE OFFICER OF TOYOTA RESEARCH INSTITUTE (TRI) AND AN EXECUTIVE FELLOW OF TOYOTA MOTOR CORPORATION

Second, what is best for the average person is not best for every person. Different people have different needs and different circumstances. In some parts of the world, people have access to highly renewable electric power and BEV rapid charging stations. In many other parts of the world, rapid chargers are rare, or electricity is generated with high carbon emissions resulting in BEVs putting more net carbon into the air over their lifetime than PHEVs and in some cases even HEVs.

So, even if the best choice for the average person someday becomes a BEV, it will not be the best way for every person to contribute to reducing carbon emissions, or for the most carbon emissions to be eliminated.

Don’t I think we should try to increase battery production, lower the carbon footprint of electric power plants, and expand rapid charging stations as quickly as possible? Of course I do.

But I also know that in many countries (including the US) much of the easier carbon reduction of electric power plants has already been achieved through conversion of coal and oil burners to natural gas (lowering carbon output by roughly half). Further improvement, such as conversion to green or blue hydrogen, or replacement of thermal power plants by new nuclear, photovoltaic, wind and geothermal plants will be harder, cost more, and take longer, at time scales comparable to and beyond the lifetime of new vehicles.

I believe, as does Toyota, that it would be a tremendous mistake for governments around the world to prescribe narrow solutions like insisting that all vehicles be BEVs.
– DR. GILL PRATT: CHIEF EXECUTIVE OFFICER OF TOYOTA RESEARCH INSTITUTE (TRI) AND AN EXECUTIVE FELLOW OF TOYOTA MOTOR CORPORATION

Ending Carbon Emissions ASAP. So where does this leave us?

The atmosphere accumulates carbon over long periods of time, so the carbon we emit now will be with us for a century or more. Our responsibility is clear: We must eliminate carbon emissions as soon as possible. As a scientist, I know that, to paraphrase Einstein, the solution of how to eliminate carbon as soon as possible should be as simple as possible, but no simpler.

As a result, I believe, as does Toyota, that it would be a tremendous mistake for governments around the world to prescribe narrow solutions like insisting that all vehicles be BEVs. Instead, the better solution is to allow manufacturers to innovate across a diversity of drivetrains and drivers to choose the low-carbon drivetrain that suits their circumstances best.

Carbon is the enemy, not ICEs. In many parts of the world for some time to come, PHEVs and even HEVs will generate comparable or less lifetime carbon than BEVs. We have open-sourced a modeling and simulation tool that shows this. Now to be clear — I still love BEVs, and Toyota expects BEVs and FCEVs will make up 15% of its U.S. sales by 2030.

We are also heavily investing in R&D on new types of batteries, including solid-state batteries and AI tools for discovering and optimising battery performance. But neither Toyota nor I think this is all we should make. By keeping HEVs, PHEVs, BEVs, and FCEVs in the lineup, 70% of Toyota’s vehicles will be electrified by 2030.

This approach — of diverse solutions for diverse circumstances — is exactly what the phrase “think globally, act locally” means to me. And I sincerely believe it is the best way to reduce the most carbon emitted into the atmosphere as soon as possible.

Meet the most affordable electric vehicle in South Africa: The MINI Cooper SE

vuyi on September 8, 2020

My interview with Hailey took place in the plush visitors area of their environmentally friendly dealership – MINI Midrand.

I was invited by the PR team at MINI South Africa to review their first ever electric car – the MINI Cooper SE.

Having spent most of the national lockdown in my sneakers I wanted to grace the momentous occasion with a cross between a formal business look and environmentally fashionable dress sense. I would be meeting Hailey Philander, Specialist: Product Communications (BMW i, BMW Motorrad and MINI) for the first time and as they say, first impressions count!

My interview with Hailey took place in the plush visitors area of their environmentally friendly dealership – MINI Midrand. Over a welcome mug of cappuccino, Hailey shared that the BMW Group has already lowered emissions per vehicle produced by more than 70 percent since 2006. Their next goal is to decrease emissions by a further 80 percent by 2030.

After discussing their other long-term strategic plans, which include introducing zero emission vehicles by year 2030 it was time for me to put the MINI Cooper SE to the Heels & Horsepower Magazine’s Green Mobility Test.

As much as I am a perfectionist for practicality, I am also a staunch advocate of ‘fashionable’ green mobility

First impressions

The first ever electric MINI looks like a standard MINI Cooper, with the exception of it being adorned with rather futuristic looking wheels – or heels as our editorial team prefers to call them. The look and feel of these 17-inch MINI Electric Power spoke 2-tone heels give the MINI Cooper SE its unique standing within the urban city environment. Coincidentally the yellow trim on the all new electric MINI matched my green stockings! Clearly green minds think alike.

As much as I am a perfectionist for practicality, I am also a staunch advocate of ‘fashionable’ green mobility. While the new electric MINI does not scream for attention, it does effortlessly exude design elements which set it apart from any other MINI Cooper on the market. These include the embossed MINI Electric logo found on the front grille and on both front fenders. To the rear, the MINI Cooper SE boasts a yellow S which can also be found on the door sills. These small details tastefully differentiate the all new electric MINI from its siblings.

Inside, the all new electric MINI Cooper SE is as spacious as any other. Premium quality materials have been used throughout and give a welcome sense of familiarity to those who know the MINI brand.

I was impressed that the electric MINI has not lost an ounce of all that makes it a fun drive.

The drive

To say I was excited to get behind the wheel of the all new electric MINI would be a gross understatement. It took a lot of effort, but I managed to curb my enthusiasm and remind myself of our publication’s criteria for the Green Mobility Test. These include driver-friendliness, technology, driving range and safety especially when navigating through bustling city traffic.

The MINI ticked all these boxes within the first 30-minutes of my powering it along the highway and within rather tight urban spaces. All the while, the grin on my face was a permanent feature. Not only did I arrive to all my different destinations safely and on time I was impressed that the electric MINI has not lost an ounce of all that makes it a fun drive.

The eery silence of electric cars is one of the global leading safety concerns for both the drivers, pedestrians and other road users.
– SONGO DIDIZA, GREEN MOBILITY GURU, DRIVING IN HEELS SOUTH AFRICA

Instead of a petrol or diesel, the MINI Cooper SE is propelled by a smooth flow of power courtesy of its 135kW motor. This explains how the engineers at MINI have managed to retain the fun factor of the tried, tested and much-loved MINI go-kart feel! It accelerates from standing to 60 km/h in just 3.9 seconds and effortlessly keeps pace with conventionally powered cars.

The eery silence of electric cars is one of the global leading safety concerns for both the drivers, pedestrians and other road users. That said it seems MINI’s engineering team skillfully addressed some of these safety concerns. All components of the electric drive are protected by means of model-specific structural features and that immediately switch off in the event of a collision.

Different driving modes increase the driving fun factor

The first purely electrically powered MINI also enables the driver to adapt the vehicle settings to the current situation on the road as well as to their own personal preferences. There are four driving modes to choose from in the electric MINI (MID, Sport, Green and Green+). As I toggled from one mode to the next, I was delighted that the dashboard lit up in different colours, in accordance with which ever mode I had selected. White is for MID, red is for Sport mode and green is for, you guessed it, Green and Green+.

In Green+ one sacrifices features such as air conditioning and seat heating in order to increase the driving range.
– songo didiza

I opted to drive in Green+ mode as this is the most environmentally friendly option. However, when in Green+ one sacrifices features such as air conditioning and seat heating in order to increase the driving range.

MINI’s one pedal drive feature is enabled by BMW’s regenerative braking technology that can be found in all its Battery Electric Vehicles and Plug in Hybrid Vehicles.

MINI eDrive Services were specifically developed for the new all-electric MINI and make electro-mobility particularly easy and convenient
– Hailey Philander, Specialist: Product Communications (BMW i, BMW Motorrad and MINI)

What is Regenerative Braking and how does it work?

Part of the characteristic driving experience in an electrically powered BMW Group model is the so-called one-pedal feeling. In urban traffic in particular, the vehicle perceptibly decelerates as soon as the driver removes their foot from the accelerator. This is called regenerative braking technology.

It is called regenerative because the energy is recaptured in the battery where it can be used again. The motor is directly coupled to the wheels, so when you lift your foot off the pedal, it works like a generator and lets the all-electric MINI slow down more quickly than a fuel-powered car would. You put some power back into your battery every time you come to a stop at the next set of traffic lights. A proper implementation of regenerative braking system extends driving range, improves braking efficiency, reduces brake wear, and improves energy conservation.

Ease of Charging – how to keep your electric charge while navigating through city effortlessly

South Africa is very much in the early stages of electric mobility compared to its US and European counterparts, however it is a first mover on the African continent.

“MINI eDrive Services were specifically developed for the new all-electric MINI and make electro-mobility particularly easy and convenient. For instance, it provides useful details such as available range, charging status and the closest charging station,” Hailey said.

For a city executive, this makes the drive even more practical. The home charging is also a seamless and simple process (unless of course, you are experiencing load-shedding). One does not actually need any complex installation or unit to charge at home. All you have to do is plug into any conventional household power socket – and relax after a long busy day at the office. I can wake up, fully rested in the morning to a ‘full tank’ of 270km driving range to start the day which can be sufficient for a week’s drive of my daily 33km city commute.

For a faster charge MINI recommends a 3-phase 11 kW MINI Wallbox connection will generally give you up to 3-times faster charging time. So, your all-electric MINI can be fully charged within around 3.5 hours. These MINI Wallboxes need to be installed by a qualified electrician.

The MINI navigation system provided me with direct access to all charging stations in the MINI Charging network as well those of the broader BMW charging network since MINI is part of the BMW Group.

Leaping into the new decade we can anticipate greater amount of driving range between the Battery Electric Vehicles, Plug in Hybrid Electric Vehicles in response to changing demands of the African city business executives looking towards making an affordable eco-conscious motoring purchase.

Pros and Cons of purchasing Electric Vehicles in South Africa

Before you rush off to your nearest MINI dealership to buy your favorite go-kart in greenie derivative, be aware that the South African government currently views earth friendly cars as luxury items. As a result, green cars attract an import duty of 25% whereas the duty charged on cars with internal combustion engines is much lower at 18%. This obviously creates a problem for both manufacturers and potential customers.

Presently there aren’t any EVs manufactured locally, even though South Africa is a major car exporter to markets in Great Britain and Europe. These countries are in the process of phasing out internal combustion engines and it is only a matter of time before the South African government finds itself in need of a more sustainable approach towards its efforts to support electric mobility – across the board – if not specifically for export purposes.

The good news though is that the introduction of the carbon tax is a move in the right direction as it acts as an incentive to sway city executives towards zero emission mobility. For this reason, I believe the introduction of an affordable vehicle such as the all new MINI Cooper SE will attract potential customers towards electric mobility.

So, did the Electric MINI pass the Green Mobility Test?

In order to pass the Green Mobility test, the Heels and Horsepower team looks at a number of elements including affordability, drivability and electric mobility features. Overall, the all-electric MINI Cooper SE tested well against our criteria as follows:

Pricing: Currently, electric vehicles aren’t cheap, but the all-electric MINI Cooper SE comes in at R642 000. This makes it the most affordable electric vehicle in South Africa.
Drivability: My initial thoughts bordered along the lines that the MINI Cooper SE might be a bit of a snooze fest given that it is a plug in electric vehicle. Thankfully I was wrong. There is absolutely no difference between driving the MINI Cooper SE and any other MINI. None of the MINI fun factors have been compromised in the production of this new greenie.
Electric mobility features are available in abundance within the new electric MINI, providing the manufacturer with an opportunity to enter a new customer segment – the eco-conscious city executive that is looking for a little bit of everything at the right price!

Final thoughts…

The new MINI Cooper SE is the first model to combine electromobility in the urban setting with the hallmark brand properties of the original in the premium segment of small cars. This gives it an intergenerational edge over its competitors.

Based on these assessments we have confidently given the MINI Cooper SE a very high 8 heels out of 10!

Are Green cars safer than ‘normal’ cars?

vuyi on July 3, 2020

Songo Didiza, a true ‘greenie’, entrepreneur and green economy expert is the founder of Green Building Design Group. She is a contributor for Driving In Heels, focusing on green mobility in the motoring sector

This past December holiday I was overjoyed to join my sisters on our annual Ubuntu road trip to the Wild Coast in the Eastern Cape. The trip was particularly interesting because some of our party were on Honda sponsored motorcycles whilst others we cocooned in the comfort of the spacious 7 seater Isuzu mu-X. We travelled a distance of over 2000kms of tarmac and rough wild coast terrain which was evenly matched by both the adventure motorcycles and the dynamically powered SUV.

The question that plagued me was ‘would I be able to drive my EV to a destination such as Coffee Bay and back without worrying about my safety?’
– Songo didiza, founder – green building design group

Our drive was pleasantly uneventful, that is until we turned off the highway and headed towards Coffee Bay when driver and riders had to employ some pretty nimble skills in order to manoeuvre between gigantic sized potholes and stray animals. It got me wondering if there were any electric vehicles (EV) on the market that would be up for this challenge?

As an EV pundit, I must say I had to scratch my head for this one. (In my previous article I had touched on the safety of EVs. This was addressed from a performance perspective. It was clear as the EV technology improves that these cars can also be held to the same performance standards as convention internal combustion engines). The question that plagued me was ‘would I be able to drive my EV to a destination such as Coffee Bay and back without worrying about my safety?’

Before I delve into the safety and durability of EVs we need to understand the different types that are out there on the market.

There are three main types of electric vehicles (EVs), classed by the degree that electricity is used as their energy source. BEVs, or battery electric vehicles, PHEVs of plug-in hybrid electric vehicles, and HEVs, or hybrid electric vehicles.

Battery Electric Vehicles, also called BEVs (and more frequently called EVs), are fully electric vehicles with rechargeable batteries and no petrol/diesel engines. Battery electric vehicles store electricity on board with high capacity battery packs. Two of these are currently available in South Africa in the form of the BMWi3, Jaguar I-PACE and the Nissan LEAF. Two of these are suitable for city driving. They are not recommended for long distance drives at the moment ( > 1000 kms).

Hybrid Electric Vehicles or HEVs, are hybrid vehicles powered by both petrol/diesel and electricity. The electric energy is generated by the car’s own braking system to recharge the battery. This is called ‘regenerative braking’ which is a process where the electric motor helps to slow the vehicle and uses some of the energy normally converted to heat by the brakes. Regular HEVs most commonly use an internal combustion engine (ICE) and electric batteries to power electric motors. Many HEVs reduce idle emissions by shutting down the ICE at idle and restarting it when needed. An HEV gets all its energy from petrol, however, the HEV’s engine is smaller and maybe run at various speeds, providing more efficiency. The Toyota Prius is one of the most commonly available HEVs within the global car market. All Prius’ sold in South Africa are HEVs.

Plug-in Hybrid Electric Vehicles or PHEVs can recharge the battery through both regenerative braking and ‘plugging in’ to an external source of electrical power. PHEVs have batteries that can be recharged by connecting a plug to an electric power source. It shares the characteristics of both conventional hybrid electric vehicles and battery electric vehicles, having an internal combustion engine and batteries for power.

While ‘standard’ hybrids can (at low speed) go about 1-3 kms before the gasoline engine turns on, PHEV models can go anywhere from 16-64 kms before their petrol/diesel engines provide assistance. Hybrid cars are all the rage these days with every automobile manufacturer moving into the forte to make its mark. Whether you are driving a cost-effective Toyota Prius or a costly BMW i8 these provide the owner with benefits like better fuel efficiency and lower environmental emissions.
