Three、Introduction to the overall scheme

1.Cell parameters: using a brand of high-quality 327000/6000mAh/3.2V battery cells
2.Finished product specification: TOPAK 18650-16S17P-51.2V-100Ah
3.Protective board: Intelligent protective board (RS485/RS232 protocol) with the following parameters and schematic diagram :
4.Other materials: fireproof epoxy resin version, insulating PET and other materials to isolate the welding point and between the core.
5.Assembling process: 4 modules of 32700-4S17P are used, with bracket support inside the battery and ventilation holes on the surface of the case, which has good heat dissipation effect.
6.Connector: The battery connector adopts 0.3mm special nickel strip, which connects the cells in series and parallel. It has good welding effect, firm welding, not easy to solder off and even heat dissipation when the battery has high current and good current conductivity.
