Application of high power electronic load to DC charging pile test

With the continuous development of electric vehicles, the demand for charging piles is increasing. In the past, the actual environment test method was usually used for the charging pile test. Now some manufacturers are also choosing electronic load test charging posts. However, during testing, engineers may encounter the following situations: When the CV mode of electronic load is used, if the minimum charging voltage of the charging pile is taken as the loading parameter value of the CV mode and gradually loaded to 700V, it is likely that the larger current value will be loaded immediately during the test (in order to stabilize the load at 700V as soon as possible, the current will climb faster). If the current overshoot time is long, the amplitude is large, will lead to the charging pile overcurrent protection. To solve this problem, high performance and high power programmable DC electronic load can solve this problem.
