Winter electric car battery is not durable how to do: 1, lead-acid battery replaced with low-temperature battery; 2. Keep charging in a constant temperature environment; 3. Choose to charge during the day.
The reality of lead acid battery resistance to low temperature is "no solution". The lead acid battery is below -10℃, and the electric vehicle battery is basically in the state of "lying down", which is difficult to use normally. For car owners in the south of the country, lead-acid batteries can continue to be used even in winter, although the battery life is reduced, but car owners in the north should consider replacing the batteries.
There are two mainstream low temperature resistance batteries, the first is lithium battery, low temperature resistance can withstand negative 15℃ or so, although it will reduce the battery life, but can ensure normal use, and in the case of 0℃ or so, the battery life will not be significantly decreased; The other is colloidal lead-acid battery, it uses solid electrolyte, a special research and development of low temperature battery, whether in the south or the north, can withstand the lowest temperature of minus 35℃, winter can be used normally.
Of course, replacing batteries is cumbersome and expensive, especially lithium and colloidal batteries, which are more expensive than ordinary lead-acid batteries. If you don't want to replace the battery at the source, you have to start with your daily vehicle, where maintaining the charging environment is a key step. The best charging environment for batteries is 25℃. On a cold winter day, try to get as close to the problem as possible.
If conditions permit, you can choose to charge it indoors, where it can be kept at a constant temperature, which is better than charging it outdoors at a low temperature. Of course, with the implementation of the policy of banning charging upstairs for electric vehicles, many communities do not have underground parking lots, and most owners can only accept the objective fact of outdoor charging. Charging during the day, the temperature is relatively high. If you can ensure that the battery charging temperature is above 0℃, you can run an extra 5km to 10km.
