A method for charging a traction battery includes obtaining a battery parameter of the traction battery that includes a state of charge and/or an open-circuit voltage, and, during a charging process of the traction battery, controlling the traction battery to discharge or stop being charged in response to the battery parameter changing by a parameter gap value. The parameter gap value is a first preset parameter gap value in a scenario in which the battery parameter of the traction battery is in a first parameter interval, and is a second preset parameter gap value in a scenario in which the battery parameter of the traction battery is in a second parameter interval. 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 the battery parameter in the second parameter interval.
