Embodiment Construction
[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] The solution of the embodiment of the present invention is mainly: the present invention acquires the current working state, current parameter and voltage parameter of the battery pack to be detected; It can improve the accuracy of differential pressure fault judgment. By combining the current working status, current parameters and voltage parameter factors, the comprehensive judgment can increase the accuracy and stability of differential pressure fault judgment. Due to the dynamic changes of current and voltage It can determine the differential pressure fault state of the battery pack to be detected in real time, which improves the efficiency of differential voltage fault judgment of the battery, and solves the problem that the battery differential pressure fault judgment method in the prior art is relatively ...
