Lead-acid battery of the electric vehicle 1 production processes, lead powder manufacturing process: the electrolytic lead melted, cast small shot, stroller batteries, lead powder delivered to the machine, for grinding, into a desired lead powder. 2, the casting process: The lead alloy melted molten lead poured into a casting stand-alone product drawings in line with the requirements of the grid. 3, Tu fill step: the aluminum powder and additives used and stir into the pastel cream machine, and then coated board machine to lead paste was applied to the grid, then cured and dried. 4, into the process: the positive, what makes a good stroller battery, the negative electrode plate placed into the slot, stroller battery 6V12AH, and its charge, the positive electrode plate active material is converted to lead dioxide, the negative plate active material is converted to velvet-like lead. Plates then dried. 5, the assembly process: the positive and negative plates touch with the polar group welded into positive group and negative group (positive and negative plates separated by separator), into the battery slot. Between the cover, carry out sealing between the pole and the battery cover. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. 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 when establishing oxygen cycle, the battery substantially fill the upper space oxygen, electrolyte separator may also lug along climbed on the bus, the bus of the alloy will be oxidized to produce lead sulfate, if the bus electrode alloy inappropriate choice of special stroller battery, impurities and crevice corrosion along these cracks will deepen, leading to very ears 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 charge and discharge process, resulting in micro-short circuit, the battery failure.
