【摘要】 为了提高新能源汽车电池续航能力，设计了一种基于域控制器的热管理系统。该系统包括底层域控制器、执行器、传感器及配套上位机。域控制器以S12ZVM作为主控芯片，MLX81325和MLX81315作为从控芯片，通过2台电子水泵和2台电子水阀控制冷却液来调节汽车电池温度。为了提高驱动电子水泵的永磁同步电机(PMSM)的同步精度，设计了一种将超前同步补偿与二阶全局快速终端滑膜控制相结合的二重交叉耦合同步控制算法。经过仿真分析与实验验证，该热管理系统能够通过不同的工作模式有效提升汽车电池热管理效率。更多还原

【Abstract】 In order to improve battery life of new energy automobiles, a heat management system based on domain controller was designed.The system included a bottom-level domain controller, an executor, a sensor and a supporting upper computer.The domain controller used S12ZVM as the main control chip, MLX81325 and MLX81315 as the secondary control chip, and controls the temperature of the car battery through two electronic water pumps and two electronic water valves.In order to improve the synchronization accuracy of the permanent magnet synchronous motor(PMSM) driving the electronic pump, a dual cross-coupled synchronization control algorithm combining advanced synchronization compensation with second-order global fast terminal synovial control was designed.Through simulation analysis and experimental validation, the thermal management system can effectively improve the thermal management efficiency of automotive batteries through different working modes.更多还原
