[0100] In this embodiment, the open-circuit charge is used in the embodiment of the present application to perform real-time correction on the current integral to obtain a corrected current integral value, and the corrected current integral value obtained is used as the current true charge of the battery, which is beneficial to improving the accuracy of the true charge estimation and avoiding the adverse effects of complex factors such as self-discharge and polarization inside the battery on the accuracy of the current true charge estimation, so that the final corrected current integral value is closer to the actual charge of the battery.

[0101] In this embodiment, obtaining the battery power evaluation data specifically includes collecting the battery discharge current through a collection chip to obtain the battery discharge current data; and also includes collecting the battery voltage through a collection chip to obtain the battery voltage data. Further, there can be multiple collection chips, which can be selected as needed, and will not be described in detail here.
