Fast charging of a 60w car can damage the battery. Long-term use of fast charging pile to charge electric vehicles, it will reduce the battery life to a certain extent, the principle of fast charging electric vehicles is the direct current directly stored in the battery, generally use direct charging mode, the output voltage basically reached 300 to 400V voltage, some even reached 50 to 100 kilowatts of voltage.
For the battery, it will cause the battery to overheat, and the speed of battery decay under long-term high temperature will be very fast.
