Can the lithium battery pack for electric vehicles be charged at low temperatures?

Can the lithium battery pack for electric vehicles be charged under low temperature conditions in winter? Lithium battery packs for electric vehicles can be charged in low temperatures in winter. When the temperature is lower than 15 degrees, the storage capacity of the electric vehicle battery will decrease, and when the temperature is 25 degrees, it is the time when the electric vehicle battery can reach the perfect storage and power generation capacity. Therefore, in the low temperature state, both the charging and storage capacity of the battery will decrease. If you want to charge in winter, it is best to put the car indoors. Generally, charging is 8 to 10 hours, which is a night. At present, there are two main types of electric vehicle battery technologies on the market, namely ternary polymer lithium batteries and lithium iron phosphate batteries. Their performance in the face of low temperatures is different, but in fact, no matter what kind of battery technology, there is a degradation of battery performance when facing a low temperature environment. In order to maintain battery performance, most electric vehicle products currently on the market will be equipped with a lithium battery pack thermostat system. That is, when the operating temperature of the battery is too low, the battery management system will take out a part of the electricity and convert it into heat energy to heat the entire battery pack. If the electric vehicle is not used for a long time, the low temperature will cause the performance degradation of the battery package, which is not conducive to extending its service life. Therefore, the battery is really afraid of cold, so try to prevent it from being parked for a long time under low temperature. Under low temperature conditions, lithium batteries generally suffer from poor charging acceptance and insufficient charging. At this time, the charging voltage must be increased, the charging time must be extended, and heat preservation and antifreeze measures must be taken to ensure sufficient charge and prolong the service life of the battery. The battery should be charged frequently. Don't wait until the battery is used up. It is better to charge the lithium battery with half. In addition, in order to prevent the battery from freezing, the battery of an electric vehicle can be placed in a house with a higher temperature when not in use, and should not be placed directly on the ground. If the battery cannot be removed, the electric car can be parked in the house overnight. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
