Car batteries can be divided into: maintenance and ordinary batteries (non-maintenance) is divided into two types of batteries ordinary batteries, dry charged batteries and maintenance-free battery categories. Battery on which we are more familiar with the use of basic passenger cars that ordinary batteries with these two types of maintenance-free batteries. At present, most of the models on the market have adopted a maintenance-free battery, while most Japanese cars, even including Lexus and Infiniti, etc. These high-end Japanese cars are also non-maintenance-free batteries, which is the ordinary batteries. The role of the separator is an ion-conductive, preventing electron transfer directly with the reducing agent and the oxidizing agent in the partition between the electrodes. Therefore, the diaphragm must be anti-corrosion and insulation material electrolyte car battery manufacturers, and has good resistance to wetting. Battery electric vehicle battery pack in series by stacking a plurality of battery components. A typical battery pack approximately 96 battery, charged to 4.2V lithium-ion battery, such a battery pack may generate the total voltage exceeds 400V. Although the automotive power supply system battery pack as a single high-voltage battery, each time for the entire battery pack is charged and discharged, but the battery control system must be considered independently of each cell. If the battery pack in a battery capacity is slightly lower than other batteries, so after multiple charge / discharge cycles car battery brand investment, the charging status will gradually deviated from the other battery. If the battery charge state is not periodically with other cell balancing, then it will eventually into a deep discharge state, causing damage, and ultimately the formation of battery failure. To prevent this from happening to the car battery, the voltage of each cell must monitor what makes a good car battery, to determine the state of charge. In addition, there must be a separate device charging or discharging the battery to the battery state of charge balance these.
