Abstract
A method for controlling the temperature of at least one battery element, a battery, and a motor vehicle that has the battery includes specifying a temperature value, and determining the cool-down behavior of the at least one battery element beginning at a first temperature. A first point in time, at which the battery temperature will have reached or fallen below the temperature value, is determined by evaluating the cool-down behavior. Subsequently, a second point in time for a beginning of the charging or discharging of the at least one battery element is determined. If tmin<t_end, heat is applied to the at least one battery element in such a manner that the battery temperature at the second point in time is higher than or equal to the temperature value. The method can be used to avoid damage to the battery element during charging and discharging of the battery element.
