Abstract:
1. A battery management control system, provided in an electric vehicle which is provided with electronic equipment including at least a driving electric motor, the battery management control system comprising: a battery, comprising: a controller, connected to the electronic equipment, wherein: one of the manager and the controller includes a map including a first map which specifies a relationship between a charging rate and a first limit of the electric power and a second map which specifies a relationship between the charging rate and a second limit of the electric power lower than the first limit; the controller calculates a first electric power value based on the first map and requests the calculated first electric power value from the manager; and when the manager controls the input and the output of the electric power to and from the battery cell based on the requested first electric power value, and the information detected by the battery cell monitor satisfies a deterioration determination condition at least one time, the manager determines that the battery cell is deteriorated, and the controller calculates a second electric power value based on the second map, wherein the deterioration determination condition includes, that the maximum input and output electric powers based on the map are not to be held for a period of time.
