If you like your EV to resemble Furnace Creek during winter (and even in summer!), it's best to get the temperature right while charging. Don't waste precious battery on the road. Similar to the above point, heating your entire EV can use significant amounts of energy - particularly if it's just you in the car. Our recommendation? Try seat and steering wheel heaters. Most EVs will have an eco-mode - use it! Eco-mode automatically adjusts the climate settings to benefit the EV's range. Cold batteries do not charge as fast as warm batteries, that's a fact. To ensure that you're charging as efficiently as you can, try to charge when. If you are lucky enough to have a garage or indoor parking space, use it! While these areas are never warm, it can make a slight difference to your.

Does winter make a difference to your battery capacity?
While these areas are never warm, it can make a slight difference to your winter battery capacity. Cold batteries do not charge as fast as warm batteries, that's a fact. To ensure that you're charging as efficiently as you can, try to charge when the battery is warm (i.e. just after driving) Be mindful of battery health throughout the year!
In the UK, winter temperatures average between 0 - 7 degrees Celsius - that's between 8 to 15 degrees colder than a lithium battery can optimally perform. Due to the internal kinetics of the battery cell, colder temperatures slow the chemical reaction. What does this mean in real life? 10 - 15% less driving range.
How to reduce battery capacity during winter?
Simple adjustments, like charging devices overnight or using thermal casings for batteries, can help reduce cold-weather inefficiencies. The decrease in lithium battery capacity during winter stems from slower chemical reactions and increased internal resistance at lower temperatures.
How does cold weather affect EV batteries?
Cold temperatures adversely affect EV batteries because they rely on chemical reactions to store and release electricity. Lithium-ion batteries – the most common cells used in electric and hybrid cars – work when lithium ions move from the anode to the cathode; cold slows this process down and restricts battery performance.
How does winter affect lithium batteries?
As winter approaches and temperatures drop, lithium batteries begin to exhibit peculiar behavior—specifically, a reduction in operational capacity, as though they've become “sleepy” from the cold. This loss of efficiency is tied to the slowed movement of lithium ions within the battery.
The chemistry of EV batteries means that the bold claims in adverts are adversely affected when the mercury plummets – and Parkers' research suggests that electric car range can typically drop by as much as a third in winter.
