Embodiments of the present application provide a method for charging a traction battery and a battery management system. The method for charging the traction battery is applied to a battery management system, where the method includes: obtaining an SOH of the traction battery; in a charging process of the traction battery, obtaining an SOC of the traction battery; determining an SOC interval value corresponding to discharging or stopping being charged of the traction battery based on the SOH of the traction battery; and when the SOC of the traction battery changes by the SOC interval value, controlling the traction battery to discharge or stop being charged. Through the technical solution, in the charging process of the traction battery, the discharging or the stopping being charged of the traction battery can be controlled to reduce the risk of lithium precipitation in the traction battery and improve the safety performance of the traction battery. Further, the SOC interval value is determined based on the SOH of the traction battery, and the SOH and the SOC of the traction battery are combined, to control discharging timing and timing of stopping being charged of the traction battery in the charging process, so that the overall charging design is more proper, and on the basis of ensuring the safety performance of the traction battery, the charging performance of the traction battery is also improved.
