Release time:

2023-06-25

The rated power of different models of electric vehicle chargers varies, usually 220w. When charging an electric vehicle charger, first insert the battery and then add the mains power; After sufficient, first cut off the mains power and then unplug the battery plug. If you unplug the battery plug before charging, especially when the charging current is high (red light), it is very easy to damage the charger.
The commonly used switch mode power supply chargers are divided into two categories: half bridge type and single excitation type, while the single excitation type is further divided into forward and flyback types. The half bridge type has high cost and good performance, and is commonly used for chargers with negative pulses; Single excitation has low cost and high market share.

Precautions for using electric vehicle chargers:
1. Generally, after 8-10 months of use, new batteries need to be inspected and maintained.
2. Generally, chargers for branded cars are screened and do not require testing. However, non matching chargers purchased separately from the market must undergo testing for the aforementioned three parameters.
3. There is a thyristor charger without a power frequency transformer, which directly rectifies the mains power to charge the battery. The current can reach 30A, and the voltage can be adjusted from 12V to 80V. Before completely cutting off the mains power, do not touch the battery. Customers who use this type of charger for freight transportation should pay special attention to safety.
