Simple changes to increase your EV battery range

Matthew Gibbons is the Managing Director of Plug&Drive, a UK manufacturer and installer of electric vehicle charge points.

Electric vehicles (EVs) are rising in popularity, but one factor that puts many drivers off is ‘range anxiety’. Each model of EV has a specific range that the manufacturer claims it can travel before needing a recharge, but even some of the largest ranges aren’t deemed enough for some.

The truth is, EV battery range really doesn’t limit drivers much more than the fuel tank size on a petrol/diesel vehicle, so it shouldn’t be a deciding factor when making the switch to electric.

If you own and drive an EV, you may have noticed that your battery range fluctuates. Every journey is different, and although you may be driving the same number of miles, you might find that a certain route at a certain time of year uses more charge than others.

When you’re driving short distances, this isn’t too much of a concern, especially if you have a charge point installed at home for easy recharging. For longer journeys, where you may be less familiar with the accessible charge points in the area, conserving your battery range can be crucial. The good news is that there are a variety of methods you can utilise to extend the range of your EV.

There are a variety of factors that can impact an EVs battery range, such as:

  • High and low temperatures
  • Terrain
  • Speed
  • Battery condition

Luckily, there are also a variety of methods for increasing your range!

Reduce the weight of the vehicle

Petrol and diesel vehicles tend to guzzle more petrol when they are weighed down, and EVs are the same, just with battery charge instead of fuel. If you are buying an EV brand new and made to order, consider selecting a more lightweight material for certain components, such as the wheels and seats.

If you decide to modify your EV in any way, consider how much weight you are adding to the vehicle. The heavier the vehicle, the more pressure is put onto the battery when driving, lowering the range. You should also try to keep the footwells, back seats and boot clear of unnecessary items that could be adding weight.

Protect the EV in extreme temperatures

Both cold and hot weather can impact an EVs battery. Cold weather is instantaneous, slowing down the chemical reactions in the battery and decreasing range. Hot weather has a more long-term effect, slowly degrading the battery.

If you have a garage to park your EV in, it’s advisable to do so when temperatures are at big highs or lows. If this isn’t an option, consider investing in a car cover to protect your EV from frost, and park your vehicle in a shaded spot if the weather is particularly warm.

Consider when to heat and cool the vehicle

Both AC and internal heating systems are very heavy on the battery. Most EVs have a pre-heat and pre-cool function that can be turned on before you head off on your journey. If your vehicle is charged at home, utilising these functions whilst the EV is plugged into the mains means that your car can be warmed or cooled prior to setting off, using none of the battery charge in the process.

Once on the road, using systems such as heated seats or heated steering wheel can add some extra heat to the interior, whilst putting much less pressure on the battery than the internal heating system. You can also open the windows to cool down the interior, but please note that driving at high speeds with the windows down can impact the aerodynamics of the vehicle, which leads nicely onto the next tip.

Maintain the aerodynamics of the vehicle

Most manufacturers will design their vehicles to be aerodynamic. The problem arises when vehicle owners decide to modify the exterior of their vehicles in some way. Extra components or attachments can increase wind resistance, putting more pressure on the battery when driving, so avoid adding any additional features that could impact the aerodynamics of your EV. Be cautious of driving at high speeds with the windows down, as this also has a negative impact on wind resistance, and in turn, battery range.

Drive efficiently

Efficient driving is a simple way to increase your battery range. Harsh acceleration and braking put more pressure on the battery, reducing its range. Try to maintain a steady speed, gradually slowing and speeding up. Excessive idling can also reduce the range, so if you’re able to plan a route that avoids heavy traffic areas, this is advised too.

Driving in eco mode puts much less pressure on the battery, so this can also increase the range of your vehicle.

Check and fill your tires regularly

The manufacturer-recommended PSI is the optimum pressure for your tires and vehicle. Having underinflated tires can cause increased resistance and pressure, draining your battery life quicker. Consider purchasing an air compressor to keep in your vehicle, for quick and easy top-ups to your tires on the go.

Utilise regenerative braking

Lots of EV models have regenerative braking, a system that recharges the battery slowly whenever the brake is pressed. Built-up, traffic-heavy areas can often drain your battery quicker, but regenerative braking can help extend your charge in these situations instead. This method is simple but effective – you most likely won’t even notice that regenerative braking is enabled, but you may well notice the increased range!

Refrain from fully charging your EV

Of course, charging your EV to 100% will provide the highest amount of miles. This is handy for long journeys but can be detrimental in the long run. The final 20% of charging is often slower, heating the battery more in the process. This can degrade the battery over time. Do not be deterred from charging to 100% if you need the full charge for your journey, or cannot regularly recharge, but if you have easy access to a charge point, charging to only 80% each time is recommended.

Some of these methods may only conserve a small amount of battery life, but on a long journey, every mile counts! Implementing a few, or all of these tips should give you a more than notable difference in your battery range, whilst maintaining the battery for a longer life span.

The competition of simulation in motorsport development

Salman Safdar, subject matter expert at Ansible Motion

The automotive and motorsport industries have long been driven by the relentless pursuit of performance, efficiency and innovation and as these sectors evolve, so do the tools and technologies that support them.

Among these, Driver-in-the-Loop (DIL) simulation stands out as a transformative force, offering unprecedented opportunities for development, testing and optimisation. From motorsport through to broader automotive OEM applications, the integration of advanced simulation tools is undoubtedly accelerating progress and redefining the boundaries of what’s possible.

At the heart of all effective simulation is the interaction between humans and technology. High-fidelity simulators provide drivers with realistic feedback that closely matches what they would experience in the real world – an approach that’s vital for optimising performance and gaining that all-important competitive edge.

The ability to simulate multiple racing cars and series underscores the versatility of modern simulators. By allowing extensive and varied test programs to be conducted in a controlled environment, teams can make quick setup changes, explore various chassis configurations, and understand track conditions without the expense and time constraints of on-track testing. This not only strengthens the collaboration between drivers and engineers but also enhances the overall development process.

Only recently, topflight motorsport teams Penske Autosport and Honda Racing Corporation USA (HRC) announced their respective investments in DIL simulation – with HRC upgrading its simulator in time for this year’s Indianapolis 500.

Capable of replicating the current Dallara-Honda Indy car, Acura ARX-06 hybrid GTP machine and a variety of Honda and Acura concept racing vehicles, Ben Schmitt, head of the Vehicle Performance Group at HRC US explains in the firm’s official press release: “The new simulator is superior in every way to our original DIL simulator. The vehicle physics models have continued to evolve from the original simulator, including the tyre models, and our data acquisition capabilities are exponentially higher than previously. The new motion platform, cockpit and vision systems create a vehicle dynamics experience for the drivers that is our closest recreation yet of real-world conditions.”

Realism is also key for those competing in the FIA ABB Formula E Championship – providing a data-rich environment where drivers can learn track layouts, optimise energy management strategies, and experiment with different race scenarios.

When it comes to gaining a competitive edge – on and off the track – engineers and drivers are looking for tools they can trust, and DIL offers the ability to replay and analyse multiple scenarios repeatedly, via a truly immersive experience that mirrors real-world conditions. However, engineers also need the capability to connect with a vehicle’s onboard powertrain ECUs via Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) systems – integration which facilitates the validation of critical components such as torque maps and electro-mechanical driver controls, ensuring that both the hardware and software are finely tuned before hitting the track.

One of the standout features of contemporary simulation environments is their ability to integrate with other advanced tools such as engineering-grade visual simulation environments – crucial for teams that need to adapt quickly to changing conditions. For example, there’s no need to wait for a real rainstorm because weather variations can be conjured up with the touch of a button; multiple tyres can be driven in rapid succession; a virtual racetrack can even be set up to loop one particularly critical track segment continuously.

While motorsport often leads in adopting cutting-edge technologies, the benefits of simulation extend well beyond the circuit. Automotive manufacturers are increasingly leveraging simulation to enhance vehicle development processes, reduce costs, shorten development cycles and reduce the environmental impacts inherent in the traditional build-and-test approach.

As the automotive and motorsport industries continue to evolve, the role of simulation will only become more critical thanks to its ability to provide a controlled, repeatable, and data-rich testing environment that is flexible as well as sustainable.

Whether it’s mastering the intricacies of a demanding street circuit or refining the dynamics of a new road car, simulation offers unparalleled opportunities to innovate and excel. As we look to the future, the seamless integration of these tools will undoubtedly expedite progress and set new standards for excellence in both motorsport and automotive development.

Could electric vehicles be the answer to energy flexibility?

Rolf Bienert, Managing and Technical Director, OpenADR Alliance

Last year, what was the Department for Business, Energy & Industrial Strategy and Ofgem published its Electric Vehicle Smart Charging Action plans to unlock the power of electric vehicle (EV) charging. Owners would have the opportunity to charge their vehicles while powering their homes with excess electricity stored in their car.

Known as vehicle to grid (V2G) or vehicle to everything (V2X), it is the communication between a vehicle and another entity. This could be the transfer of electricity stored in an EV to the home, the grid, or to other destinations. V2X requires bi-directional energy flow from the charger to the vehicle and bi- or unidirectional flow from the charger to the destination, depending on how it is being used.

While there are V2X pilots already out there, it’s considered an emerging technology. The Government is backing it with its V2X Innovation Programme with the aim of addressing barriers to enabling energy flexibility from EV charging. Phase 1 will support development of V2X bi-directional charging prototype hardware, software or business models, while phase 2 will support small scale V2X demonstrations.

The programme is part of the Flexibility Innovation Programme which looks to enable large-scale widespread electricity system flexibility through smart, flexible, secure, and accessible technologies – and will fund innovation across a range of key smart energy applications.

As part of the initiative, the Government will also fund Demand Side Response (DSR) projects activated through both the Innovation Programme and its Interoperable Demand Side Response Programme (IDSR) designed to support innovation and design of IDSR systems. DSR and energy flexibility is becoming increasingly important as demand for energy grows.

The EV potential

EVs offer a potential energy resource, especially at peak times when the electricity grid is under pressure. Designed to power cars weighing two tonnes or more, EV batteries are large, especially when compared to other potential energy resources.

While a typical solar system for the home is around 10kWh, electric car batteries range from 30kWh or more. A Jaguar i-Pace is 85kWh while the Tesla model S has a 100kWh battery, which offers a much larger resource. This means that a fully powered EV could support an average home for several days.

But to make this a reality the technology needs to be in place first to ensure there is a stable, reliable and secure supply of power. Most EV charging systems are already connected via apps and control platforms with pre-set systems, so easy to access and easy to use. But, owners will need to factor in possible additional hardware costs, including invertors for charging and discharging the power.

The vehicle owner must also have control over what they want to do. For example, how much of the charge from the car battery they want to make available to the grid and how much they want to leave in the vehicle.

The concept of bi-directional charging means that vehicles need to be designed with bi-directional power flow in mind and Electric Vehicle Supply Equipment will have to be upgraded as Electric Vehicle Power Exchange Equipment (EVPE).

Critical success factors

Open standards will be also critical to the success of this opportunity, and to ensure the charging infrastructure for V2X and V2G use cases is fit for purpose.

There are also lifecycle implications for the battery that need to be addressed as bi-directional charging can lead to degradation and shortening of battery life. Typically EVs are sold with an eight-year battery life, but this depends on the model, so drivers might be reluctant to add extra wear and tear, or pay for new batteries before time.

There is also the question of power quality. With more and more high-powered invertors pushing power into the grid, it could lead to questions about power quality that is not up to standard, and that may require periodic grid code adjustments.

But before this becomes reality, it has to be something that EV owners want. The industry is looking to educate users about the benefits and opportunities of V2X, but is it enough? We need a unified message, from automotive companies and OEMs, to government, and a concerted effort to promote new smart energy initiatives.

While plans are not yet agreed with regards to a ban on the sale on new petrol and diesel vehicles, figures from the IEA show that by 2035, one in four vehicles on the road will be electric. So, it’s time to raise awareness the opportunities of these programs.

With trials already happening in the UK, US, and other markets, I’m optimistic that it could become a disruptor market for this technology.
