Why do electric car batteries have a shorter range in winter? Can the problem of electric cars having a shorter range in winter be solved?

Winter is here, and the temperature is low, even below zero! Every winter, friends who use electric vehicles worry about the battery life of electric vehicles. Normally, the temperature is 25 degrees Celsius. When the temperature drops by one degree Celsius, the corresponding battery capacity will drop by one percent, which will eventually lead to a short battery life and a short range of electric vehicles! So can the problem of short battery life of electric vehicles in winter be solved? Now, let's learn about the relevant knowledge with Encyclopedia Knowledge Network!

Why do electric vehicles have a shorter range in winter?

1. The biggest reason is the cold weather. The normal operating temperature of the battery is about 25 degrees Celsius. If the temperature is too low, it is not conducive to the chemical reaction inside the battery. If the chemical reaction is not fully reacted, the required electrical energy cannot be achieved, which is what we often call failure to fully charge. Therefore, low temperature will lead to a short battery life;

2. The last reason: wind resistance increases. Because the air density is high and the more clothes you wear, the wind resistance will also increase, which speeds up the consumption of battery energy, so you will feel that the battery life is short.

Regarding the concerns of many people, whether it can be recovered after winter, the clear answer here is that it can be recovered, but not 100%. After all, you have used it for half a year, and you can calculate it based on the normal half-year cycle loss. It can be said that recovery is possible, but 100% recovery is impossible.

Can the problem of short battery life of electric vehicles in winter be solved?

For electric vehicles, the most critical factor regarding mileage is the battery, so the only way to maintain the mileage is to protect the battery.

① Don't step on the accelerator hard when driving to avoid wasting electricity, just like starting a fuel car too fast will waste fuel.

② In winter, the temperature is relatively low, and many people will choose to turn on the air conditioner and heater, which also consumes a lot of electricity, so to a certain extent, it also reduces the mileage. However, it is recommended that if the car has a steering wheel heating or seat heating function, you can turn it on and use it, so you don’t have to turn on the air conditioner.

③Parking of electric vehicles in winter is also critical. It is best to choose to park in an underground parking lot with higher temperature. If conditions permit, you can park the car indoors, such as in a garage.

How to prevent electric vehicle batteries from becoming less durable in winter?

1. Indoor charging

The temperature in winter is very low, so it is best to choose indoor charging, which can enhance the chemical reaction in the battery and extend the battery life. Be careful not to overuse or charge frequently. It is best to charge the electric car when the remaining power is about 30%.

2. Remove the battery and place it indoors

If the house does not have a garage, the electric car battery can be moved out of the storage room to maintain the battery charge. This can also extend its life

3. Put the protective cover on the battery

If the temperature is too low in winter, it is best to cover the electric vehicle battery with an insulating cover. This can protect the battery and thus improve the performance of the electric vehicle in winter.
