Electric vehicle as a modern travelArcadenearbyThe important way, the use of its charger is also one of the issues that car owners are very concerned about. Recently, some car owners reported that their electric car charger green light has been on, but the charging has not stopped, what on earth is going on? Next,ArcadenearbyI will explain in detail the causes of this phenomenon and how to solve it.
oneArcadenearby. The working principle of charger
The working principle of the electric car charger is to convert alternating current into direct current, and then charge the battery through the control circuit. During the charging process, the indicator light of the charger will change according to the change of the charging state. in general, the green light indicates that the charging has been completed. But if the charger is still working after the green light, the following possibilities need to be considered.
twoArcadenearby. The floating charging stage in the charging process
In the process of charging the electric vehicle battery, there is a stage called "floating charge". The purpose of this stage is to maintain the voltage of the battery within a certain range to prevent the battery from being overcharged. The current in the floating charge stage is very small, so even if the green light is on, the charger is still working, which is normal.
3. Charger failure
If the floating charging stage is too long, or if the charger is still working after the green light is on, you need to consider whether there is something wrong with the charger. At this point, you can replace the charger for testing, or contact professional maintenance personnel for inspection.
4. Battery problem
In addition to the problems with the charger itself, the battery may also cause the battery to charge after the green light is on. If the battery is aging or damaged, its internal voltage may fluctuate, making it impossible for the charger to accurately judge the charging status. In this case, the battery needs to be checked and replaced.
The following is a table of causes and solutions to some common problems:
The cause of the problem is that the battery voltage fluctuates too long in the floating charging stage, and the charger can not accurately judge the charging status to replace the charger for testing, or contact professional maintenance personnel to check the failure of the charger, the internal components of the charger are damaged, resulting in the inability to accurately control the charging process to replace the charger, or contact professional maintenance personnel to check the battery aging or damage battery internal voltage fluctuation. As a result, the charger can not accurately judge the charging status to check and replace the battery.Some problems in the use of electric car chargers are caused by improper operation or aging equipment. As car owners, we need to learn the correct use method, regular inspection and maintenance, in order to ensure the safety and performance of electric vehicles.
