The principles of fast charging and slow charging of new energy vehicles are different.
Fast charge is the use of high voltage and high current charging, and direct current is directly input into the battery through the charging pile to shorten the charging time. This charging method has high charging efficiency, but it may have a certain impact on battery life.
Slow charge is to convert alternating current into direct current through the charging pile, and then input direct current into the battery through the car charger. This charging method takes a relatively long time to charge, but can extend battery life. In short, fast charging and slow charging have advantages and disadvantages, and which charging method to choose depends on the actual needs and situations of users.
