Charging pile load bank is a special field detection device for electric vehicle charging pile, is mainly used in ac charging pile and dc charging product field installation and debugging and function verification, can be widely used in charging equipment manufacturers, power departments, units at all levels of the electric car dc charging pile, the adjustment of the previou research and development, factory test and so on.

As the charging equipment of electric vehicles, the safety and reliability of charging piles are very important, which is related to the safety of users, so it is very important to test the load of charging piles. At present, some manufacturers use the actual environment test method, that is, use a charging pile to charge the battery and then test it, but in practice, this will have disadvantages:

1. The working condition of charging pile in actual charging cannot be judged in real time;

2. The output status of charging pile cannot be accurately tested;

3. low efficiency, unable to carry out rapid repeatable test, high cost;
