The invention relates to an electric vehicle double-battery multi-load intelligent control system and an electric vehicle. The system comprises a first power battery system, a second power battery system, a first loading load controller, a second loading load controller, a power distribution module and a whole vehicle controller. The vehicle control unit is used for obtaining the remaining electric quantity of the first power battery system and the remaining electric quantity of the second power battery system, and when the remaining electric quantity of the second power battery system is larger than a first preset value, the second power battery system is switched to drive the second loading load through the power distribution module, and the first power battery system drives the first loading load through the power distribution module; and when the residual electric quantity of the second power battery system is smaller than a first preset value, the first power battery system is switched to drive the first loading load and the second loading load through the power distribution module, and the second power battery system is controlled to limit the power or stop working. Shutdown of the second power battery system due to an over-temperature fault is avoided, and the use cost is reduced.
本发明涉及一种电动车辆双电池多负载智能控制系统及电动车辆,所述系统包括第一动力电池系统、第二动力电池系统、第一上装负载控制器、第二上装负载控制器、配电模块以及整车控制器;所述整车控制器用于获取第一动力电池系统及第二动力电池系统的剩余电量,当第二动力电池系统的剩余电量大于第一预设值时,则通过配电模块切换至第二动力电池系统驱动第二上装负载以及第一动力电池系统驱动第一上装负载;当第二动力电池系统的剩余电量小于第一预设值时,则通过配电模块切换至第一动力电池系统驱动第一上装负载及第二上装负载,以及控制第二动力电池系统的限制功率或者停止工作。避免第二动力电池系统因为过温故障停机,减少使用成本。
