What happens if your car freezes in the winter?
That means that your battery, which has been weakened by the cold, actually has to do more to get the engine moving so it can start. If there’s any water in the fuel lines (there shouldn’t be, but it happens), sub-zero temperatures can cause that water to freeze, blocking the flow of fuel.

Do EV batteries degrade over time?
As with other devices powered by lithium-ion cells, the amount of charge the battery can hold will decrease as the battery pack degrades over time. The battery in your smartphone, for example, might start to degrade after just a couple of years of use. Thankfully EV batteries are built sturdier than that and the technology is constantly improving.
Do cars start slower in the cold?
Cold temperatures affect the chemical process inside the battery and reduce its ability to hold a charge. It also thickens engine oil, increasing friction in the starter motor and forcing it to work harder.
Why are cars hard to start when it’s cold?
There are three reasons why cars are hard to start when it is cold. Reason 1 – Gasoline, like any other liquid, evaporates less when it is cold. You have seen this — if you pour water onto a hot sidewalk it will evaporate a lot faster than it will from a cooler place like a shady sidewalk.
