Lithium battery maintenance methods in winter

      According to the information provided by experts, under the condition that the charging current is 5A, the charging time at the ambient temperature of -25℃ is 63% slower than the charging time at 25℃.

      Although the low temperature environment has little effect on the discharge performance of the battery, it will seriously affect the charging performance of the battery and greatly shorten the life of the battery. There are two main aspects to the battery technology winter solution for low temperature environment, one is the progress of battery technology, and the other is the maintenance of electric vehicle battery in winter. For electric vehicle lithium battery maintenance methods in winter: In addition to relying on the technological progress of lithium battery factories, consumers can also use some simple methods to maintain electric vehicle batteries in winter.

   （1）Pay attention to the charging method, try not to charge the battery in low temperature conditions

     (2) When charging in winter, you can use the method of charging several times. When the battery is hot, you can charge more at one time.

     (3) Keep the battery fully charged. In winter, when the battery discharge exceeds 50%, the electrolyte will be in danger of freezing. Therefore, the battery should try to keep it above 50% in winter.

     (4) Every other period Time to start the car, charge it, don't let the battery discharge too much, don't let the electric car sit outside for too long in the winter. In this way, I believe that our lithium battery electric vehicle will be safe this winter.
