Why a current-switchable charger failed to switch the current?


We recently received some feedback from an American user about the functionality of his 16/32A switchable charger which had been charging his car at only 16A since it couldn’t be switched to 32A. So it took the customer a long time to charge his car each time. He believed that our charger was somehow defective and contacted the manufacturer of the charger, BESEN.


We were glad to solve usage problems for our users as a manufacturer of electric vehicle chargers after receiving the feedback. First, we checked the user's charger model which was a normal 16/32A switchable charger. Besides, we asked the user to provide some photos of the charger when it was working. From the photo, we saw that the charger had a brand-new surface, with a button for switching the current and prompt icons for different currents, which indicated that the charger was a normal functioning switchable device. Therefore, we speculated that another reason why the charger couldn’t switch the current: the user's current switching method was wrong. We communicated with the user again and found that the user switched the current after the wall end plug and car end plug of the charger were inserted, which was wrong. In order to protect the safety of the charger and the circuit, our charger isn’t allowed to switch the current during the charging process. The step of switching the current needs to be performed by the user before the charger is connected to the car. That is, the user needs to connect the charger’ plug to the wall socket first, then switch the current. After confirming the charging current, the user can finally connect the charger to the car, and the charger will charge the car with the adjusted current.



We gave the user the guidance for switching the current and then he managed to charge his car at 32A. Before using the charger, we recommend that users understand the instructions for use of the charger in advance and use the correct charging method to charge.
