Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a power battery test control device. Background technique [0002] Lithium-ion power battery system needs a series of tests such as function and electrical performance before loading. In the preparation stage of the performance test, there are problems such as switching of test channels, unreliable connection of test cables and harnesses, and time-consuming problems. During the performance test, the test circuit is easily affected by external factors and problems occur, resulting in burnout of the battery pack BMS and high-voltage electrical components. Fire, resulting in safety hazards and material loss. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a power battery test control device, which improves the problem of burnout and fire of the battery system BMS high-volt...
