The maintenance method of the electric vehicle charger does not charge when the light is on.
The electric vehicle charger light is not charging, and the maintenance method is as follows:
If the power supply is not charged, it will also cause the light to be on and not charging. Check that the charger is not connected from the power supply.
The charger indicator is abnormal, resulting in no charging. Check if the charger indicator is normal.
Whether the connection between the charger and the battery is disconnected. Check whether the connection cable between the charger and the battery is firmly connected, if it is not firm, it may lead to poor contact, causing the charger to not charge.
Whether the battery is damaged. The battery itself has a service life, if it is used improperly or quality problems may cause damage to the battery, you can check whether the battery has liquid flowing out.
First of all, we need to understand the structure and principle of an EV charger. An electric vehicle charger is mainly composed of a power supply, a control circuit, and a charging indicator. When the charger is plugged into a power source, the power supply converts the alternating current into direct current suitable for battery charging through the conversion of the transformer. At the same time, the control circuit will detect the voltage and current of the battery and adjust it as needed to ensure that the battery can be charged normally. The charging indicator will light up while charging, indicating that the charger is charging the battery.
If the EV charger lights on but does not charge, then the first thing we need to check is whether the charger is connected to the power supply properly. If the connection is not normal, you will need to plug and unplug the charger again to make sure that the power supply is well connected to the charger.
Secondly, we want to check if the charger indicator is normal. If the charger's indicator light doesn't light up, then there may be a fault with the control circuit. At this point, we need to disassemble the charger and check if there is any damage to the components in the control circuit. If there are damaged components, we need to replace them with new ones.
Next, we need to check if the connection between the charger and the battery is normal. If the connection is not working properly, it may cause the charger to fail to charge the battery. At this time, we need to check whether the connection cable between the charger and the battery is secure, and if it is found loose or broken, it needs to be reconnected or replaced.
Finally, we want to check if there is a problem with the battery. If the battery itself is damaged, then the charger cannot charge the battery. At this time, we need to check whether there is liquid outflow from the battery, if there is liquid outflow, it means that the battery has been damaged and needs to be replaced with a new one.
In the process of repairing EV chargers, we need to pay attention to safety issues. When disassembling the charger, you need to disconnect the power supply first to avoid electric shock accidents. At the same time, when checking the battery, it is necessary to pay attention to the voltage and current of the battery to avoid danger.
In conclusion, the situation where the EV charger is not charging when the light is on can be caused by a variety of reasons. We need to investigate the possible causes one by one and take appropriate repair measures to solve the problem. At the same time, we need to pay attention to safety issues and ensure the safety of the repair process. Search Topic Full Time Challenge December
