The batteries in most EV’s need some kind of passive or active cooling. Some cars are using liquid cooling.
Tesla, BMW i-3 and i-8, Chevy Volt, Ford Focus, Jaguar i-Pace, and LG Chem’s lithium-ion batteries all use some form of liquid cooling system. Since electric vehicles are still a relatively new technology, there have been problems maintaining temperature range and uniformity in extreme temperatures even when using a liquid cooling system.
That’s not a reason to not get an EV but they all have some form of waste heat and some have fluid systems, pumps, gaskets, and seals. They just have less of all of it.
That and suspension components still need to be greased. Plus electric cars tend to be a little heavier, often time with large wheels, meaning more wear and tear.
