The invention provides an automobile start-stop system and energy recovery system based on a super capacitor and relates to the technical field of automobile control. The system comprises an ECU (electronic control unit), an industrial bus, an intelligent generator, a starter, a DCDC (DC to DC) module, a super capacitor, a storage battery and an electric appliance for a whole automobile. The ECU is further connected with the intelligent generator through an industrial bus, and the intelligent generator is connected with an electric appliance for the whole vehicle in parallel and connected withthe DCDC module in series, the ECU is further connected with the DCDC module through the industrial bus, and the storage battery and the electric appliance for a whole automobile are connected in parallel and then connected with the DCDC module in series. The super capacitor supplies power to the starter, and the storage battery supplies power to the whole vehicle electric appliance, so that a vehicle start-stop power supply and a whole vehicle electric appliance power supply independently supply power. According to the invention, the technical problem that the vehicle power supply system isnot stable enough because the voltage of the storage battery is too low due to large-current discharge in the starting process of the vehicle is solved. And the powerful charging receiving capabilityof the super capacitor is also utilized to improve the vehicle energy recovery efficiency.

    本发明提供了一种基于超级电容的汽车起停系统与能量回收系统,涉及汽车控制技术领域,包括ECU、工业总线、智能发电机、起动机、DCDC模块、超级电容、蓄电池以及整车用电器,ECU通过工业总线与智能发电机连接,智能发电机与起动机及超级电容并联并与DCDC模块串联;ECU还通过工业总线与DCDC模块连接,蓄电池和整车用电器并联并与DCDC模块串联;超级电容为起动机供电,蓄电池为整车用电器供电,使得车辆起停电源与整车用电器电源独立供电。通过本发明解决了汽车在起动过程中大电流放电导致蓄电池电压过低,导致车辆电源系统不够稳定的技术问题。还利用超级电容强大的充电接收能力,提升车辆能量回收的效率。
