1. First open the battery cover of the electric vehicle and remove its 6 hard hats. Inject distilled water into each well with a syringe. After charging, let the battery stand for 30 minutes and discharge all the power in the battery through resistance. After discharge, the battery can be charged by pulse charging to increase its capacity. After charging, use a syringe to draw excess water from each hole.
2. Before cleaning and maintaining the battery, clean the dust on the appearance of the repaired battery and remove dirt and rust from the upper surface of the terminal. Turn the exhaust plug, observe the electrolyte inside the battery, measure the specific gravity of the electrolyte, adjust the specific gravity of the electrolyte, adjust the pre-charge and discharge test capacity, repair the connected positive and negative output repair to the positive and negative battery column, open the repair, repair the battery.
The initial repair time should be more than 10 hours, and then the battery capacity should be measured according to 1.5. When the battery capacity rises to more than 70% of the nominal capacity, the repair is complete. If the capacity increase is not large, you can continue to repair, repair for 20 hours. Typically, batteries that have been stored for a year need two repairs before they can be restored to their pre-storage condition.
Electric vehicle battery is the power source of electric vehicles, electric vehicles are almost equipped with lead battery, lead battery cost is low, cost-effective. This battery is rechargeable and can be used over and over again, so it is called a "lead battery". In 1860, Prandtl, France, invented a battery with lead as an electrode. This is the precursor of lead batteries.
The advantage of lead-acid battery is that the electromotive force is stable when discharge, the disadvantage is less than energy, corrosive to the environment. Lead-acid battery has stable working voltage, wide range of temperature and current, hundreds of cycles of charging and discharging, good energy storage performance, low cost, so it has been widely used.
