Electric vehicle charger is the basic configuration of electric vehicles. The charger has become a frequent replacement of electric vehicle accessories. What should be paid attention to when choosing an electric vehicle charger?

1. Determine the battery voltage V of your electric car or the output voltage of the original charger. 1 Look at the original charger to determine the voltage: the general battery voltage is 48V, the corresponding original charger output voltage is about 59V; 60V battery, the corresponding original output voltage is 73.5V. 2 Look at the battery to determine the voltage: Generally, there are several batteries in a battery pack. The model is 6-DZM-12 / 20, which is 6, indicating that each battery is 12V. So you see your own electric car has several batteries, 4 batteries is 48V. For the 8-DZM-12 / 20 battery, each battery is 16V, and the four batteries are 64V.

2. Determine the battery capacity AH of your electric vehicle battery or the output current of the original charger. 1 Judging the capacity of the original charger: The output current of the original charger is 1.8A, which means that the battery is 12AH. 2 Look at the battery to determine the voltage: Generally, the batteries in the battery box have written models, such as 6-DZM-12, where 12 indicates a 12AH battery, and 6-DZM-20, 20 indicates a 20AH battery. 3 Judging based on the mileage of a single charge: Generally speaking, a battery of about 1 year is full of 25-40 kilometers for a single charge, and a 12AH charger is more suitable. For a distance of 45-60 kilometers, 20AH is more suitable.

3. Determine the positive and negative shapes of the charger interface suitable for your electric vehicle. There are four more common interfaces on the market, T-shaped prefix, three vertical-shaped prefix, mid-horizontal-shaped prefix, and round head.
