Electric car battery failure in the form of a thermal runaway due to the charging voltage is too high, the current is too large, causing the battery temperature, and finally to the battery deformation, cracking and failure. 2, corrosion under normal circumstances negative bus, bus no corrosion problems, but in VRLA batteries, Luyuan electric car battery, when establishing the oxygen cycle, the battery substantially fill the upper space oxygen, electrolyte separator may climb on the bus along the lug, bus alloy will be oxidized to produce lead sulfate, if the bus electrode alloy inappropriate choice of new electric vehicle batteries, impurities and crevice corrosion along these cracks will deepen , resulting in very ear and bus disengaged negative plate failure. 3, membrane perforation caused by short circuit of individual species diaphragm aperture greater use may cause big hole, the active substance can pass through the large hole in the discharge process, electric vehicle batteries, causing micro-short circuit, the battery failure.

Electric car battery maintenance routine anti-acid chemistry bolt Maintenance: In order to achieve the purpose of anti-acid suppository anti-acid, the process will be used in anti-acid bolt tightened, avoid removed. Usually pay attention to clean, periodically (years) Remove with water not higher than 50 ℃ flush dirt on the surface of the dust plug anti-acid, must not be immersed in water. Maintenance battery slot: battery slot should always be kept clean, the newly installed battery should dry battery acid or water surface. To prevent a short circuit during initial charging, the battery should be cleaned periodically after the operation, can also be 5% of alkaline, alcohol, aliphatic hydrocarbons wipe gently.
