Description

technical field

[0001] The invention relates to a testing device for a battery pack management system, in particular to a test platform for the battery pack management system. Background technique

[0002] Batteries are widely used in various fields, especially in electric vehicles in recent years, power battery components such as lithium-ion batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lead-acid batteries, etc. are regarded as one of the key components.

[0003] In the existing power battery components, an electronic control device is included, which is called a battery pack management system (hereinafter referred to as BMS). The battery pack management system monitors the operating parameters of the power battery pack such as voltage, total voltage, temperature, charge and discharge current, etc., and performs safety protection and balanced management on the battery pack based on this information, so as to prolong the life of the power battery pack ...
