23 pin 776228-4 New Energy Electric Vehicle PCB Board End Controller

The plates are divided into positive plates and negative plates. Mix lead powder and dilute sulfuric acid to form a paste and apply it on the grid to get the raw plate. The raw plate is dried by hot air, and then put into dilute sulfuric acid for chemical conversion (in the production process of the battery, the process of charging the plate The process is called "formation", and the positive and negative plates can be obtained after generally charging for 18-20 hours. During the charging process, the plate connected to the positive pole of the charger is the positive plate, and its active material is lead dioxide (PbO2), which is dark brown; the plate connected to the negative pole of the charger is the negative plate, and its active material is spongy lead. (Pb), dark gray.
The charge capacity of a single plate is limited. In order to increase the capacity of the battery, multiple positive and negative plates are connected in parallel and welded with bus bars to form positive and negative plate groups respectively. The structure is shown in Figure 1-4. . There are poles cast on the bus bar; gaps are left between the pole plates. When installing, the positive and negative plates of each piece are fitted together, and the separator is inserted in the middle and then put into the battery slot to form a single cell battery.
