| Abstract |
This paper proposes paralleled structure of LDC for an electrical vehicle, unlike conventional integral structure, paralleled structure of LDC controls each module of battery independently to solve the temperature unbalance problem among each module during discharging period. Temperature balance control between modules was performed by controlling the amount of discharging current for its corresponding temperature of each module of HVBAT, and temperature fluctuation was confirmed through a thermal camera. Data was collected by experiment about characteristic fluctuation of a battery according to temperature and validity of proposed control method is also proved by experiment. |
