We found that after the use of electric vehicles for a period of time, the capacity of the battery slowly decreases, and the distance traveled is getting shorter and shorter, which is why? It is understood that the emergence of this situation is not a problem with the quality of the battery, usually caused by incorrect use of the battery premature aging, resulting in the biggest culprit of electric vehicle battery capacity reduction - battery water loss.

Battery repair recharge

Some people question that the vast majority of electric vehicles are maintenance-free lead-acid batteries, which are sealed and maintenance-free, why is there a "water loss" phenomenon?

In fact, once the battery is overcharged, large current discharge, internal resistance increase, short circuit and other problems, it is easy to generate heat and form water steam, a very small part will be lost, over time, the battery will appear "water loss" state. Long-term and can not occur electrolytic chemical reaction, severe "water loss" will make the electrolyte metamorphic black or become hard.

The battery water loss of electric vehicles is actually a very serious problem, the lower the degree may lead to a reduction in the service life of the battery, the higher the degree may lead to spontaneous combustion of the electric vehicle battery, which affects the life safety of the user. So, what should we do if the electric vehicle battery loses water?

The first step is to pry open the cover plate above the electric vehicle battery.

The current production of electric vehicle battery brands are ABS adhesive, some are buckle connected, some are skateboards, when prying open must be based on the connection of the battery, do not hit too hard, damage the cover.

Second, open the rubber cap to reveal the vent.

There are six rubber caps on the battery to exhaust the gas, which are opened to reveal vents through which the inside of the battery can be seen. The bottom valve of the exhaust hole of some batteries can be rotated to open, and this can be opened through this.

The third step, open the end cover, water.

Under normal circumstances, the surface of the electric vehicle battery is wet, and if the water loss is serious, it will dry up. At this time, it is recommended to use the battery water nozzle for water supply maintenance. Battery water gun is small and light, easy to carry, can effectively solve the problem of inaccurate manual water control, too much or not enough water, battery water gun has a key water refill function, water full induction stop, improve the safety of battery water, effectively extend the battery life, and low price of water gun, can save high manual maintenance costs.

Lham battery watering gun is a battery water maintenance tool independently developed by Lianhong. Built-in water pump, mobile power supply, liquid level sensing circuit, can easily fill the battery water, one key water supply, automatic induction shut down, can effectively ensure the consistency of water level, can effectively improve the efficiency of water maintenance, to ensure the consistency of battery unit characteristics after water maintenance. Improve battery performance and service life.
