BATTERY MANAGING METHOD AND DEVICE, AND VEHICLE

A method and device for managing a battery and a vehicle are provided. The method comprises: acquiring battery state parameters; comparing the battery state parameters with a plurality of aging parameter thresholds respectively to determine a target aging level of the battery; and then determining target charge/discharge parameters corresponding to the target aging level according to pre-stored correlations between aging levels and charge/discharge parameters. According to the technical solution of the present application, the target charge/discharge parameters are determined according to the target aging level, such that different charge/discharge parameters may be used in aging stages of a whole life cycle of the battery respectively, thereby slowing down an aging speed of the battery to a certain extent, and reducing a safety risk caused by aging; and in addition, the battery state parameters are compared with the plurality of aging parameter thresholds respectively, thereby more accurately and efficiently determining the aging level of the battery.
