Title:
BATTERY MANAGEMENT METHOD AND APPARATUS, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/143669
Kind Code:
A1
Abstract:
Provided are a battery management method and apparatus, and a vehicle. The method comprises: first acquiring a battery state parameter of an electric vehicle; if the battery state parameter is between a first preset threshold value and a second preset threshold value, determining a first charging upper limit parameter corresponding to the first preset threshold value, and a second charging upper limit parameter corresponding to the second preset threshold value; and then determining a target charging upper limit parameter according to the first preset threshold value, the second preset threshold value, the first charging upper limit parameter and the second charging upper limit parameter. By means of the technical solution in the present application, an interval range where a target charging upper limit parameter is located is determined according to an interval range where a battery state parameter is located; the target charging upper limit parameter linearly decreases, within the corresponding interval range, in step with with the increase of the battery state parameter, and therefore, a user is not made aware of the endurance change of a whole vehicle; and different charging upper limit parameters can be set at various stages of a battery, thereby slowing down the service life attenuation speed of the battery, and reducing the safety risk.
