The battery of the electric car will have a decline in battery capacity after using a period of time. So how can I make the electric car battery longer? 1. Unbalanced repair method: find out the battery, voltage, self-discharge, battery internal resistance, etc.

2. Water repair method: open the cover above the battery. Some battery covers are ABS adhesive, some batteries are connected to.

Some is a skateboard. Note that when you open the cover, don't damage the cover. At this time, you can see the rubber cap of 6 exhaust valves.

Open the rubber cap, expose the exhaust hole, can see the inside of the battery through the exhaust hole. Some battery exhaust valve bases can be rotated, and can be rotated open the exhaust valve base without opening the rubber exhaust valve. Some fillers around some batteries.

Open the cover, use the flashlight, see if there is a dry phenomenon in the small hole, that is, the battery is lost. The polar plate of the battery is wrapped with white glass fiber cotton, and the normal situation should be humid. Insert distilled water with a dropper is injected into the battery from the exhaust hole.

Cover the exhaust hole with a breathable shutter to prevent dust from falling into the exhaust hole. It is best to use medical secondary distilled water. The principle of hydrating is Ning less than many.

Not enough, more, more acid specific gravity decline, battery capacity is less. No relevant experience can be grasped by 5ml each well. It is best to look at the plus, wet, bright crystalline, Water Wang.

Wet is just right, bright crystals, and the water is too much. Special note: hydrating tool uses straws such as glass, plastic. It is recommended to use medical disposable syringes, easy to use and convenient.

The hydrating tool does not use any metal-containing instrument, the syringe should be pulled to the metal needle, and the plastic tube is used. 3. Sulfate repair method: repair the vulcanized battery to repair the Kuye repair instrument, using a fuzzy digital control theory, by measuring the battery status, when charging, discharge, continuously issuing positive and negative frequency conversion microparticles, with 10 to 20 hours Time, remove hard sulfate in the battery.

4. Polar softening repair method: After the battery is discharged from 10.5V, use the bulb deep to discharge 1-5 hours.

Then use the activator, activation repair. 5. Short-circuit repair method: water battery, can make a clear hole, make the short-circuited lead powder! Electric vehicle battery can quickly short-circuit the positive and negative poles, the short circuit is burn! 6.

Open circuit repair method: 100A Detect battery voltage 0V is open, using a single measurement method, the place where the opening is measured, the welding is good.
