Because the combination of fast charge and slow charge needs to overcome many factors, there is no existing condition to merge them into one, the first use of fast charge and fast charge mode is \"simple and rough\" : direct current is directly stored in the power battery; The slow charge is converted from AC to DC by the car charger, and then charged to the power battery. From the working principle of fast charging, it is fundamentally different from slow charging, fast charging uses DC charging, the voltage is directly input to the vehicle's power battery, and the charging board does not need the corresponding voltage conversion to ensure the charging speed.
