The importance of the battery Once the power loss occurs, the engine will be unable to start, so how to avoid this situation, first of all, you must understand the cause of the battery power loss, and then take measures to restore it.
Causes of battery loss
From the composition of the battery, we can know that the rechargeable battery converts the internal chemical substances into electrical energy, and converts the electrical energy into chemical energy during charging, and then circulates accordingly. Generally, the truck is a lead-acid battery, and the interior is mainly electrolyte and grid ( Electrode), there are many active substances with lead paste attached to the surface, and these active substances are discharged after chemical reaction with the internal electrolyte.
Therefore, even if the lead-acid battery is not connected to the power supply, there will be a discharge process, but the amount of natural discharge is relatively small and slow, so if the vehicle is not started for charging for a long time, the battery will lose power. The service life is also related to the consumption of chemical reactions. After a certain number of years, the chemical substances are consumed to a certain extent, and the discharge needs of the vehicle cannot be met.
How to balance the voltage of different cells in a lead-acid battery pack?
Lead-acid batteries and lithium batteries have certain things in common, that is, they are afraid of low temperature in winter, and the discharge capacity of the battery will decrease with the drop of temperature, so the power of electric vehicles in winter is weak. The thicker the oil, the more difficult it is to start, which puts pressure on the starter and the battery.
I believe that after the above series of introductions, everyone also understands the reasons why the battery will run out of power. Next, let’s talk about how to repair the battery after it loses power.
How to repair the lead-acid battery after it loses power?
After the battery loses power, it can be charged with a fast charging pile with a repair function to activate the battery and restore it to normal. In addition, the battery that cannot be charged due to power loss can also be repaired by pulse repair method, battery parallel charging method, etc. The pulse repair method is to use a high-frequency positive and negative pulse generator to break down the crystallized lead sulfate. The large lead sulfate will be dissolved and destroyed, and cannot continue to grow. The vulcanization of the battery is resolved, and the battery can be charged normally. Different from the pulse repair method, the battery parallel charging method does not need the help of an instrument, only one charged battery of the same type is needed. The method is to connect two batteries in parallel and continue charging for several hours, and the battery that has lost power can be used normally.
Usually, if there is a problem with the lead-acid battery, it is necessary to find the cause when repairing it, so as to prescribe the right medicine. If the electrical performance of the lead-acid battery fails, it can be repaired by adding a chemical activator, replenishing the electrolyte, and using the variable amplitude pulse method. In addition, the scanning resonance frequency technology is also a “good recipe” to deal with the failure of the electrical performance of lead-acid batteries. And if the problem with the lead-acid battery is that the battery case is damaged, it can be repaired using bonding technology or hot-melt bonding technology.
