Embodiments of the present application provide a method for charging a traction battery and a battery management system, which can effectively ensure the safety performance of the battery. The method includes: obtaining a battery parameter of the traction battery, the battery parameter comprising a state of charge SOC and/or an open-circuit voltage OCV; and during a charging process of the traction battery, controlling the traction battery to discharge or stop being charged when the battery parameter of the traction battery changes by a parameter gap value, where when the battery parameter of the traction battery is in a first parameter interval, the parameter gap value is a first preset parameter gap value; and when the battery parameter of the traction battery is in a second parameter interval, the parameter gap value is a second preset parameter gap value, where the first preset parameter gap value is greater than the second preset parameter gap value, and the battery parameter in the first parameter interval is less than that in the second parameter interval.
