SYSTEM AND METHOD OF CONTROLLING A MAXIMUM CHARGE LEVEL

Abstract: a computer system has processing circuitry to control charging of a high-voltage energy storage system of a vehicle. the processing circuitry obtains data of at least one geographic zone comprising a road with a downhill slope, determines a regenerative charge power of an electric traction motor of the vehicle during operation of at least a portion of the downhill slope, determines a charge power ability of the high-voltage energy storage system when the vehicle arrives to the portion of the downhill slope, in response to the regenerative charge power exceeding the charge power ability at the portion of the downhill slope, sets a reduced maximum charge level of the high-voltage energy storage system, and controls charging of the high-voltage energy storage system at the current charging position to an energy level to, or below, the reduced maximum charge level.
