Electric car batteries commonly used several repair methods

The battery of electric vehicles in use after a period of time, battery capacity decline phenomenon. So, how can let the electric battery longer? Take a look at below small make up for all the collected about simple repair method of electric vehicle battery, in order to prolong the service life of your battery.
1. The imbalance
Repair methods: find the capacity, voltage, self-discharge batteries, battery internal resistance, etc have been used together.
2. The water loss
Repair method: pry open at the top of the battery cover plate. Some battery cover plate is ABS adhesive joint, some of the battery is connected. Have a plenty of skateboarding. Pay attention to pry the cover plate, don't damage the cover plate. Then you can see 6 exhaust valve rubber caps. Open the rubber cap, revealing a vent through the vent can see inside the battery. Some batteries can unscrew the exhaust valve base, can not open the exhaust valve rubber and spin sacking valve base. Some cells around the rubber cap and some padding. Open the lid, according with a flashlight, see if there is a phenomenon of dry holes inside, if the battery fluid loss. Battery polar plate is made of glass fiber cotton wrapped in white, normal should be wet. By a vent into the battery with the dropper to inhale the distilled water. With good water battery made of breathable mask cover the vent, to prevent the dust into the vent. It is better to medical secondary distilled water. Hydrating principle is rather less not more. Can add enough, more than the decline in the proportion of acid, battery capacity will be less than. No experience is 5 ml per hole. It is best to look at, damp, twinkle, liquid. Wet just, twinkle is much, liquid is too much.
Special tip: hydrating tools using glass, such as plastic straws. Recommend the use of medical disposable syringes, easy to use and convenient measurement. Hydrating instrument cannot use any metal bearing, syringes should pull needles, metal casing section plastic tube after use.
3. The sulfuric acid salinization
Repair method: use sulphur battery repair instrument repair, fuzzy digital control theory, by measuring the battery status, at the same time of charge and discharge from the positive and negative frequency particle wave, with 10 to 20 hours of time, remove the battery after the crystallization of hard lead sulfate.
4. Plate softening
Repair method: after check 10.5 V battery discharge, using light bulb deep discharge from 1 to 5 hours. Then use the activation device, activation of repair.
5. A short circuit
Battery repair method: water, can punch is clear, will short circuit the lead powder out! Electric car batteries, short-circuit is negative, can quickly burn out where the short circuit!
6. Open circuit
Repair method: 0 v 100 a test battery voltage for open circuit, measured with a single method, measure the open circuit, welding is good.
Use the multimeter to measure the battery open circuit place!
