have your say

From what you have learned, how efficient do you think EVs (electric vehicles) are in extreme heat or extreme cold?

from what I've read and personally experienced, high-powered electronic devices with batteries such as flashlights and phones drain faster in very hot and cold temperatures. I would say this is likely more pronounced among electric vehicles since a lower battery charge would mean your vehicle would also weaken in power output. The heat wave hitting the temperate regions of the northern hemisphere would provide good data on the performance of EVs during high temperatures.

cold weather affects range more. 25% less range @ 0°c on highway driving.

up to 50% less in urban traffic. ev’s also use the battery for heat, ice cars do not.

heat doesn’t affect them as much, maybe 2-5% reduced range.

Yeah, cold is a bigger problem than heat. Its going back 10 plus years, but the original Nissan Leaf used an electric heater for the cabin and that proved to be a big drain on the battery. EVs sold now use a heat pump, which much more efficient. Petrol cars in winter just use waste heat from the engine.

Its different for folks in the city, but here in the countryside, it is not unusual for folks to have space for many cars. I do not own multiple cars simply because I do not want to pay multiples of car tax. I would happily own an EV that was short range and didn't work in winter if I didn't have to pay a whole load of taxes just to legally drive it 1m or more on a road.

Does it really matter what I think? The data from actual testing and real-world documentation is what ought to matter.

If the question is, “Does lower battery performance in extreme heat or cold influence your decision to use an EV?” then this is something I could have an opinion about.

Heat and cold absolutely affect EV batteries in a detrimental manner, sharply reducing the actual range (physics & chemistry of the battery), whereas ICE vehicles are far less affected.

Furthermore, EVs generally weigh about 500kg MORE than similarly sized ICE vehicles which also negativity affects the actual range and significantly reduces the life of the tires(also wear much faster due to the rapid torque applications of starting and stopping). Rapid tire wear increases the carbon footprint of EVs.
