The battery of electric vehicle is mostly sealed and maintenance-free battery, its core component is the battery, which determines the battery life. When the battery life deteriorates, adding a refill to the battery can restore it? Let's find out.

Let's start with what is a refill?

The common way of adding liquid to the electric vehicle battery repair, there are a variety of options such as distilled water, electrolyte, repair liquid, these "liquid" what is the difference? The details are as follows:

1. Distilled water: This is a kind of high purity pure water, does not contain minerals and impurities, does not have electrical conductivity;

2. Electrolyte: electrolyte, composed of water and sulfuric acid, will be added in battery production, which can also be understood as battery stock solution;

3. Repair solution: This is a product in recent years, the main component is distilled water, sulfuric acid, repair formula, it contains sulfuric acid ratio will be lower than the electrolyte.

Since distilled water, electrolyte, and repair solution can all be used to refill electric vehicle batteries, which of these three is better? In fact, this mainly depends on what battery deficiency, so need to discuss separately. If our electric car battery is simply short of water, only need to add distilled water, if the battery is short of water and acid, you can directly add electrolyte, and repair liquid is a good commodity, generally speaking, the price will be more expensive, more suitable for novice use will not dilute.

Due to the improper charging of electric vehicles, frequent use of fast charging and other reasons, it will lead to the reduction of dilute sulfuric acid in the battery, which is commonly known as no water, at this time there will be charging dissatisfaction. So, to add some supplementary fluid to electric cars, is a certain effect.

So how do you add water?

First of all, to confirm that your battery is not really short of water, after a few hours of charging the battery will not heat, if the heat is short of water, if the heat is fine. In fact, electric vehicles do not need to ask others to discharge water, such as driving to fast underpressure state when you can disassemble the water, you can do it, configure a set of battery watering gun, connect the hose to the water inlet, and put the end into the distilled water, the muzzle limit stop to adjust to the appropriate position, the muzzle into the battery injection plug, press the water switch, can be a key to add water, Water full induction stop.

Adding liquid to the battery is a common repair method after the failure of the battery, but it is still recommended that you do not blindly add liquid, adding the wrong liquid not only will not repair the battery, may make the battery durability worse. Therefore, we must pay attention to battery maintenance at ordinary times.
