Electric car battery common six major faults and repair methods

Electric car batteries are inevitably encountered during use, then how do these faults solve it? First, the battery's lossless fault has an important representation of battery capacity, which causes thermal out-of control and positive electrode deformation, and battery shape expansion. Repair method: open the cover of the electric car battery; open the rubber cap, reveal the exhaust hole; observe whether the electric car battery has a dry phenomenon through the exhaust hole, if there is a hydrating. In addition, it is recommended to use medical disposable syringes and secondary distilled water, add water to be cautious, not enough.

Second, battery unbalanced faults It is important to behave as small batteries that have problems in the battery pack, and other good batteries cannot be used normally. Repair method: About battery unbalanced faults, users can find consistent batteries such as capacity, voltage, self-discharge, battery internal resistance. Third, battery sulfate failure It is important to behave as generating white hard sulfate crystals on a plate, and it is very difficult to convert the lead in active substance when charging.

Repair method: The repair instrument can be repaired, by measuring the battery status, in the process of charging, the positive and negative frequency conversion microplic wave, by about 15 hours, can remove the crystalline and hardening sulfate in the battery. However, it should be noted that this is generally only suitable for slight sulfate. If the sulfate is more serious, it is necessary to replace the new battery.

Fourth, the battery polar panel softening fault It is important that the surface of the positive pole plate is soft until the start of the solid-gradual looseness until it becomes a paste, and the battery capacity will result in a decrease in battery capacity due to the decrease in surface area. Repair method: After the battery is discharged from 10.5V, the light bulb is discharged from 1 to 5 hours.

Then use the activator, activation repair. In this case, there is a certain chance to repair, but the situation is heavy, it can only be replaced. 5.

The battery short circuit fault has an important manifestation to cause self-contained electricity when the positive and negative polarity is touched, and the battery life is seriously affected. Repair method: Remove the lead slag lead block at the short circuit, recovery from new parts paper paper. 6.

The battery opening fault has an important manifestation as a certain place in the circuit, which is too large, and the current cannot pass. Repair method: Use the multimeter to check the various connections of the battery inside, find the disconnection, then refolde it. In fact, in daily life, we must increase the maintenance of the battery so that the battery life can be extended to maximize battery life.

In addition, if you encounter these six battery failures, it is recommended to repair the maintenance point as soon as possible to avoid new problems.
