The difference between the electric car charger 20e and 30e is that 20e is for the 12a battery, and 30e is for the 20a charging.
Because the electrical appliances must match the voltage, these two batteries are 60 volts, so there is no problem with the same, the difference is that 30AH is one-third longer than 20AH charging time.

Working principle: 220v AC is filtered by T0 bidirectional filter to suppress interference, D1 rectifier is pulsed DC, and then filtered by C11 to form stable DC of about 300V. U1 is a TL3842 PWM integrated circuit.
The difference between the electric car charger 20e and 30e is that 20e is for the 12a battery, and 30e is for the 20a charging.
For example, if your charger is 64V20e, then the battery it is charged is 64v14a, if your charger is written 6430e, then the battery it is charged is 64V20a, this charger is marked with 20e and 30e most of the original battery of green source electric vehicles.
