A STRATEGY TO CONTROL BATTERY STATE OF CHARGE BASED ON VEHICLE VELOCITY |
摘要 |
The present invention is to provide an improved strategy for actively controlling battery state of charge (SOC) as a function of the vehicle's kinetic energy. A vehicle system controller (VSC) can vary a target battery SOC as a function of vehicle speed based on either vehicle kinetic energy or the square of vehicle speed. The VSC can set a maximum battery SOC limit using vehicle velocity and actively control a rate of charging the battery and determine a target battery SOC as a balance between the charge time and the charge current. The VSC can determine a target battery SOC based on a predetermined constant and a predetermined offset value. Target battery SOC is increased as vehicle speed increases until the maximum battery SOC limit is reached.
