Product manual:
1. Application of battery pack short circuit equipment: It is mainly used for the safety verification test of power battery cells, monomers, modules, PACK and other battery packs and structural parts of new energy projects. Simulate the short-circuit situation of battery cells, monomers, modules and PACK battery packs during use, transportation and storage to evaluate the safety performance of the battery. Present the actual use of battery packs or systems in the laboratory, find and solve problems, optimize product design, and improve product quality.
2. The battery pack short-circuit equipment is composed of a short-circuit control box, a vacuum arc extinguishing device, a short-circuit terminal wiring, a data acquisition system and a computer for data analysis.
Overview of battery pack short-circuit equipment design: The short-circuit equipment is designed based on the requirements of various battery short-circuit test standards, that is, it meets CB31467.31CB31485\UU25801SAE
J24641SAEJ2929\UN38.3ECER100\IEC6213UL1642\ Qc / T 743 and “”863i Plan”" Energy-Saving and New Energy Vehicle Major Projects – 2008 EV Lithium-ion Power Battery Performance Test Specifications and other standards; short-circuit devices must meet the internal resistance range according to the standard <5m or >5m2&<10m or >10m2&く20m or >40m&く50m or >80m&100m2 to obtain the maximum short-circuit current of the test; the circuit design of the short-circuit device can also withstand the impact of a large current of 16000A, so we choose industrial grade mechanical suction”
