Abstract
Embodiments of the present application provide a method for charging a power battery and a battery management system, which can effectively improve the charging speed of the power battery on the basis of ensuring the safety performance of the power battery. The method for charging a power battery is applied to a battery management system for the power battery. The method includes: determining a negative electrode potential safety threshold according to a battery state parameter of the power battery, the battery state parameter comprising at least one of the state of charge (SOC), the temperature, and the state of health (SOH) of the power battery; and adjusting a charging request current for the power battery based on a negative electrode potential of the power battery and the negative electrode potential safety threshold during a charging process for the power battery.
