What to do if the 1.2V NiMH battery of an electric car cannot be charged during use

Many people wonder why the same brand of 1.2V NiMH battery is scrapped after one or two years of use, while others are still powerful after three or four years? Regarding this issue, the technicians said that there is no other reason for the 1.2V NiMH battery to be scrapped, just because of improper maintenance. As the saying goes, electric car batteries are not broken but broken by charging. So, facing the many problems of electric car batteries, how to solve them? Let me explain to you one by one why the 1.2V NiMH battery cannot be charged.

1. The 1.2V NiMH battery has reached the end of its life

No matter how good the product is, it has a service life and cannot be used for a lifetime. Therefore, when you find that the 1.2V NiMH battery cannot be charged, think carefully about how many years it has been since it was purchased and used, and whether it is within the normal life range. If it has exceeded the life, then it should be replaced or repaired in time.

2. The fuse is broken

Everyone knows that if the fuse in the switch is broken, it will definitely be out of power. Similarly, if the fuse inside the 1.2V NiMH battery is broken, the 1.2V NiMH battery will also be out of power. What you need to do at this time is to go to a specialty store to replace the fuse, and never change it yourself.

3. Poor contact

When the contact between the fuse tube and the fuse holder is poor, the 1.2V NiMH battery will not be fully charged or fully charged. At this time, what the user needs to do is to adjust the position of the two to make them in good contact, so that the problem of not being fully charged or fully charged can be solved.

4. Poor contact with the power supply

This is a very easy event. According to survey data, 30% of users will not be able to charge or fully charge due to poor contact with the power supply. At this time, what you need to do is to unplug the power supply and plug it back in to ensure that the contact is smooth, and then see if it is not fully charged or fully charged.

5. Poor positive and negative poles

According to professionals, when the plug-in in the 1.2V NiMH battery has poor contact or the lead is broken, it will also cause no voltage, especially whether the connection between the positive and negative poles of the dial is normal, which has a great impact on the 1.2V NiMH battery of the electric vehicle. It can be handled by re-plugging or changing the line.

6. Circuit break

When the circuit board in the dial is broken, it is very normal for the 1.2V NiMH battery to be fully charged or fully charged. What you need to do at this time is to replace or repair the circuit board to ensure normal contact.
