- Jan 17, 2018-

The test of the performance of electric vehicle charger can be judged by measuring the actual charging parameters of the charger. Use a group of battery, battery, ammeter, charger connection, connect the mains, measure its charging current and voltage, and record. Then, adjust the variable resistance, observe the current and voltage changes and make a record, know that the charger shows sufficient or termination of charge, the measured parameters and the normal charging parameters for comparison, such as large deviation, you can determine the charge may not be normal.
