Abstract—This paper introduces servo control system. The servo control system is the optimization technique to reduce energy consumption for air-conditioning (A/C) system of battery electric vehicle (BEV). The system modeling of heat system in passenger room and battery pack are derived to represent in mathematic model. The characteristic of loss in Li-ion batteries during discharge are examined by experiment. The relationship between discharge rate and power loss in battery is tested by experiment kit. A new control system based on servo control system is presented to optimize the energy consumption. The simulation results exhibit that energy consumption and power loss of servo control system outperforms rather than PID and On-Off control systems and the energy loss of servo control system is 91,971 Wh, which is less than the PID and On-Off control systems about 0.1% and 0.25%, respectively.
