Because slow charging is better for the battery, the fast charging current is larger than the slow charging current, and slow charging can protect the battery and extend its service life. Fast charging refers to providing short-time fast charging service with large current within 20 minutes to 2 hours of electric vehicle parking.
Fast charging is to increase the current of the charging battery in the maximum range that the battery can withstand to achieve the requirements of replenishment and endurance of the vehicle battery, while slow charging is to reduce the input current and voltage of the battery to achieve, and naturally slow charging is more conducive to the maintenance of the battery than fast charging.
Because the battery of the new energy vehicle itself has a discharge function, it will also lose electrical energy when placed for a long time
