How to choose a safe electric vehicle charger?

Jun 27, 2022by 甜茶

The charger is an important accessory of the electric vehicle. Due to the design of the electric vehicle is integral, the parameters and specifications of the charger should be consistent with the electric vehicle. If the electric vehicle owner uses an unqualified charger, it is easy to cause the electric vehicle to malfunction. Next, Full Young Power will tell you how to choose a safe charger.

  1. Determine the output current of the charger according to the battery capacity.
The output current of the selected charger is generally slightly larger than the capacity of the electric vehicle battery. For example, if the electric vehicle battery is 12AH, a charger with an output current of 1.8A can generally be used. If it is a 20AH battery, the charger output current can be selected as 26 to 30AH.
 
  1. Determine the output voltage of the charger according to the battery voltage.
Taking a 48V electric vehicle battery as an example, the output voltage of its corresponding charger is generally around 59V; while for a 60V battery, the corresponding charger output voltage is 73.5V. Therefore, when we choose a charger, we should pay attention to the output voltage must match the battery of the electric vehicle. If the charger voltage is too high, the battery will be over charged; and if the charger voltage is too low, the electric vehicle will not be fully charged.
 
  1. Choose a charger with a suitable interface (DC connector).
In addition to the current and voltage of the charger, the interface of the charger is also a very important detail to pay attention to. At present, the more common electric vehicle charger interfaces on the market mainly include XLR connector, T-shape 3 pin connector, Anderson connector and round head connector. Users must choose a charger with the same shape as the electric vehicle interface.
 
  1. It is preferred to use a smart charger.
If the user does not take the initiative to power off the ordinary charger, the charger will continue to charge. When the charging time exceeds ten hours, the battery will heat up, and even lead to bulge and scrapping. Therefore, to ensure the life of the battery, it is necessary to provide it with a scientific charging current, so the smart charger came into being. The smart charger can provide the corresponding charging mode and algorithm according to the characteristics of the battery, so as to achieve the best charging effect, so the car owner should try to use the smart charger.
 
Tips from Full Young Power,
When purchasing electric vehicle chargers, car owners should choose a charger whose parameters, specifications and interfaces match the battery. It's best to buy a smart charger with an automatic power-off function, which will make the electric vehicle safer to use and have a longer battery life.
