In the process of daily use of electric vehicles, many friends have encountered situations where the electric vehicle battery suddenly cannot be charged, or has been charged for a long time but has not been fully charged. At this time, most people will think that the battery is not working.

Actually, it's not always the case. Sometimes, it's not necessarily because the battery is broken. There are also these specific reasons. Today, let's take a look at the specific reasons and solutions for the battery not being able to charge or not being fully charged!

1、 Poor contact

1. Poor power contact

This is a very easy occurrence. According to survey data, 30% of users will experience electric vehicle batteries being unable to charge or not fully charged due to poor contact with the power supply. At this time, it is necessary to unplug the power supply, plug it back in, ensure that the contact is unobstructed, and then check whether it is fully charged or not.

2. Poor insurance contact

When there is poor contact between the safety tube and the safety seat, there may also be situations where the electric vehicle battery cannot be charged or is not fully charged. At this time, the user needs to adjust the positions of the two to ensure good contact, which can solve the problem of insufficient charging or insufficient charging.

2、 Open circuit

When the circuit board in the dial is broken, it is very normal for the battery to be under charged or the electric vehicle battery to not charge. At this point, it is necessary to replace or repair the circuit board to ensure normal contact.

3、 The fuse is broken

Everyone knows that if the fuse inside the switch is broken, it will definitely run out of power. Similarly, if the fuse inside the battery is broken, the battery will run out of charge. What to do at this time is to go to a specialty store to replace the fuse, and never replace it yourself.

4、 There is a problem with the positive and negative poles

According to professionals, poor contact of the plug in the battery or open circuit of the lead can also lead to no voltage, especially if the connection between the positive and negative terminals of the dial is normal, which has a significant impact on the electric vehicle battery. It can be processed by reinserting or changing wires.

5、 Charger damaged

Some users are accustomed to carrying chargers with their vehicles, and the phenomenon of chargers being damaged and unable to charge due to bumps is also very easy to occur. So it is very important to check if the charger is functioning properly. When not charging, do not connect the electric bike charger to the AC power source without load for a long time, and it is strictly prohibited to open the power lock of the electric bike when charging directly on the electric bike to prevent burning the charger.

6、 The battery has reached its lifespan

Even the best product has a lifespan and cannot be used for a lifetime. Therefore, when you find that an electric vehicle battery is charging, you should carefully recall how many years have passed since purchase and use, whether it is within the normal lifespan range, and if it has exceeded its lifespan, it should be replaced or repaired in a timely manner.
