Batteries in electric vehicles charge slower when it’s cold because low temperatures partially solidify the liquid electrolyte in lithium-ion batteries. This slows down ion transfer, which restricts charging speeds.

The simple way to remedy this problem is to pre-heat your vehicle if it has this feature. For example, Tesla’s have a battery pre-heat mode.

If you don’t have a battery pre-heat mode, your charger might have one, letting you plug in to pre-heat your battery before charging.

Otherwise, try and park somewhere warm!
