The invention discloses a high-voltage switching control system and a high-voltage switching control method for a double-battery-pack vehicle type, which are used for controlling the switching between a main power battery pack and a standby power battery pack equipped on an electric vehicle, and the main power battery pack and the standby power battery pack are connected in parallel and then are connected to a load main loop to supply power to a load. A main IGBT module is arranged in series in a high-voltage loop where the main power battery pack is located, and a standby IGBT module is arranged in series in a high-voltage loop where the standby power battery pack is located; the IGBT driving module and the control module are correspondingly matched with the main IGBT module and the standby IGBT module respectively; and the control module determines a current PWM duty ratio according to a current voltage value and a current current value of a load main loop and/or a power switching instruction sent by a driver, and controls the on-off of the main IGBT module and the standby IGBT module according to the current PWM duty ratio, so that the main power battery pack and the standby power battery pack are switched to supply power to the load.

    本发明公开了一种用于双电池包车型的高压切换控制系统及控制方法,用于控制电动车辆上配备的主动力电池包与备用动力电池包之间的切换,所述主动力电池包和所述备用动力电池包并联后接入负载主回路并为负载供电,所述主动力电池包所在高压回路串联设置有主IGBT模块,所述备用动力电池包所在高压回路串联设置有备用IGBT模块;还包括分别与所述主IGBT模块和备用IGBT模块对应匹配的IGBT驱动模块和控制模块;所述控制模块根据负载主回路的当前电压值、当前电流值和/或驾驶员发出的动力切换指令确定当前PWM占空比,并以该当前PWM占空比控制所述主IGBT模块和所述备用IGBT模块的通断,以实现主动力电池包与备用动力电池包之间切换为负载供电。
