Charge up quickly. According to the relevant information, charging power less than 20kW is called slow charge, charging power greater than or equal to 20kW is called fast charge, fast charge has no upper limit power, for example, Tesla's fast charge power is 120kW, Porsche's fast charge can reach 350kW, because the greater the charging power, the battery can be charged more in a shorter period of time. So high-end electric vehicles are promoting fast charging.
20kw is a slow charge. Because as long as it is greater than 20 KWH, it is fast charging, which is a measurement standard for electric vehicles, but 20 KWH is not greater than 20 KWH, so 20 KWH is slow charging
