如有对接意向,请电话垂询010-68918340

一种燃料电池汽车混合动力系统

一种燃料电池汽车混合动力系统,由燃料电池、蓄电池、DC/DC变换器、驱动电机、传动系、辅助电器、显示装置、控制器和通讯网络共九大系统组成。DC/DC变换器10的输入端与燃料电池发电系统8连接,输出端分别连接电机控制器11和动力电池组23,电机控制器11 将来自燃料电池和动力电池组的直流电转换为交流电,输入驱动电机12,电能通过驱动电机12转化为转矩从其输出轴输出,再依次经过飞轮13、离合器14、变速箱15、主减速器16传递到车轮,驱动车辆行驶。显示装置包括驾驶员信息显示屏2和车载多媒体显示屏4;控制系统包括驾驶员踏板1和整车控制器3各子系统通过CAN通讯网络27进行数据传递。整车具有六种工作状态。

Hybridpower system of fuel cell vehicle

Ahybrid power system of a fuel cell vehicle is composed of nine systems of afuel cell, a storage battery, a DC/DC converter, a driving motor, a transmissionsystem, an auxiliary electrical apparatus, a display device, controllers and a communicationnetwork. The input end of the DC/DC converter 10 is connected with a fuel cell electricitygeneration system 8, and the output end of the DC/DC converter is connected withthe motor controller 11 and a power battery pack 23; direct currents from the fuelcell and the power battery pack are converted into alternating currents throughthe motor controller 11 to be input into the driving motor; and electric energyis converted into torque through the driving motor 12 to be output from anoutput shaft of the driving motor and then transmitted to wheels though aflywheel 13, a clutch 14, a gearbox 15 and a main speed reducer 16 in sequenceto drive the vehicle to travel. The display device comprises a driverinformation display screen 2 and a vehicle-mounted multimedia display screen 4;and the control system comprises a driver pedal 1 and the whole vehiclecontroller 3. All the subsystems transmit data through the CAN communicationnetwork 27. The whole vehicle has six working states.
