[color=rgb(51, 51, 51) !important]Power battery PACK is generally composed of five major systems. 1. Assembly process [color=rgb(51, 51, 51) !important]Power battery PACK is generally composed of five major systems. [color=rgb(51, 51, 51) !important]How are these five systems assembled together to form a complete and mechanically reliable battery PACK? It depends on the assembly process. [color=rgb(51, 51, 51) !important] The assembly process of PACK is actually somewhat similar to the engine assembly process of traditional fuel vehicles. [color=rgb(51, 51, 51) !important] The five major systems are connected together through bolts, nuts, cable ties, clamps, wiring harness nails and other connectors to form an assembly. 2. Airtightness testing process [color=rgb(51, 51, 51) !important] The power battery PACK is generally installed under the seat or trunk of a new energy vehicle and is directly in contact with the outside world. Once high voltage electricity comes into contact with water, you can imagine the consequences through common sense. Therefore, when new energy vehicles wade through water, the battery PACK needs to have good sealing. [color=rgb(51, 51, 51) !important] The airtightness test in the manufacturing process of power battery PACK is divided into two links: [color=rgb(51, 51, 51) !important] 1) Airtightness test at the thermal management system level; [color=rgb(51, 51, 51) !important] 2) Airtightness test at the PACK level; [color=rgb(51, 51, 51) !important] The protection level system drafted by the International Electrotechnical Commission (IEC) stipulates that the power battery PACK must reach the IP67 level. [color=rgb(51, 51, 51) !important] At the Shanghai Auto Show in April 2017, SAIC Passenger Vehicle showed off its awesome high-level airtight protection technology. The entire PACK in a charged state was placed in a goldfish tank and soaked for 7 days. The goldfish was intact and no water entered the PACK. 3. Software flashing process [color=rgb(51, 51, 51) !important] 4. Electrical performance testing process A power battery PACK manufacturing company in Shandong is recruiting a senior battery PACK process engineer with high salary. The treatment is generous.
