What should be done if an electric vehicle battery cannot be charged during use?

Many people are puzzled as to why batteries of the same brand fail after only one or two years of use in one household, while others still function well after three or four years? Regarding this issue, technicians stated that there is no other reason for the battery to fail except for improper maintenance. As the saying goes, the reason why the electric vehicle battery is not worn out but is depleted by charging is this. So, when it comes to the numerous problems of electric vehicle batteries, how should they be solved? Let me explain one by one to you all why the battery can't be charged.

1. The battery has reached its lifespan.

Even the best products have a usage period. They cannot be used forever. So when you find that the battery won't charge, you should carefully think about it. How many years have passed since you bought and started using it? Is it within the normal lifespan range? If it has exceeded the lifespan, then you should replace or repair it in time.

2. The fuse has blown.

As we all know, if the fuse inside the circuit breaker is broken, there will be no electricity. Similarly, if the fuse inside the battery is broken, the battery will also lose its power. At this time, what needs to be done is to go to a specialized store to replace the fuse. Do not try to replace it randomly by yourself.

3. Poor Contact

When there is poor contact between the fuse and the fuse holder, charging problems such as insufficient or incomplete charging may occur. In this case, the user needs to adjust the positions of the two to ensure proper contact. Once this is done, the problem of insufficient or incomplete charging can be resolved.

4. Poor contact with the power supply

This is a very common occurrence. According to the survey data, 30% of users will fail to charge their devices properly due to poor contact with the power source. In such cases, what needs to be done is to unplug the power source, reinsert it, ensure there is no obstruction of contact, and then check if the charging is insufficient or not complete.

5. There are problems with the positive and negative electrodes.

According to experts, when the plug inside the battery is not properly connected or the leads are broken, it can also cause no voltage. In particular, the normality of the connection between the positive and negative terminals of the dashboard has a significant impact on the battery of an electric vehicle. It can be dealt with by re-plugging or replacing the wires.

6. Circuit Breaker

When the circuit board inside the dial breaks down, it is quite normal that the battery cannot be fully charged or cannot be charged at all. At this point, the task is to replace or repair the circuit board to ensure proper contact.

From the above six points, it can be seen that the quality of the internal structure of an electric vehicle battery is extremely important. If the quality is poor, problems such as fuse breakage, poor contact, no voltage between the positive and negative poles, and short circuits will occur frequently, and the probability of battery failure will be very high. However, if the quality is good, then all of these will hardly become a problem.
