Slow charge, because the power battery capacity of the plug-in hybrid type of new energy vehicles is generally installed, due to installation space, weight and cost factors, it will not exceed 20kwh.
The slow charge has been upgraded from the original 3.5kw(16A) to 7kw, meaning that this battery-friendly charging time will not exceed 3 hours at most; Fast charging power is more than 30kw, fast charging mode is charged to 80%, in order to protect the battery life, the current becomes smaller, the time becomes longer, so the advantages of fast charging are not obvious compared with slow charging, and fast charging even if it is controlled in this way, the battery life is still affected.
