<p>Really low and really high temperatures can impact an electric vehicle’s battery
range. Currently, the operating temperatures for electric vehicle battery cells are
-20°C to +60°C. Vehicle manufacturers compensate for this at pack level through pre-conditioning
as well as heating and cooling systems, the drawback being that these draw energy.
Applications in aerospace and defence have even more challenging operating temperatures.
The Government has committed £274m to the Industrial Strategy’s Faraday Battery Challenge
which includes understanding the effects of temperature further. The Challenge is
supporting battery R&D from the Faraday Institution’s academic research through
Innovate UK’s programme of collaborative R&D and to scale-up in the cutting-edge
UK Battery Industrialisation Centre. One of the aims of the Faraday programme is to
improve the operating range of battery cells, including to -40°C to +80°C by 2035
therefore enabling better performance and efficiency at higher and lower ambient temperatures.</p><p>
</p><p>Thermal loads from heating, ventilation and air-conditioning affect the battery
range of electrical vehicles and is most critical for vehicles like refrigerated trucks.
The Office for Low Emission Vehicle’s Integrated Delivery Programme is funding R&D
projects aiming to maximise the efficiency of the electric powertrain and significantly
extend an electric vehicle’s range further.</p><p> </p>
