Used for electric vehicle integrated electric source module of the present utility model comprises a housing and is fixed on temperature sensor on the housing, the circuit board of DC-DC transducer and the circuit board of vehicle-mounted charge machine are installed in the described housing, the circuit board of the circuit board of described DC-DC transducer and vehicle-mounted charge machine is electrically connected by wire harness, and is connected with temperature sensor respectively.
The circuit board of DC-DC transducer and the circuit board of vehicle-mounted charge machine are placed in the housing altogether, DC-DC transducer and vehicle-mounted charge machine are become one, thereby directly be installed on the vehicle body as a global facility, not only can simplify the overall heat radiation volume of DC-DC transducer and vehicle-mounted charge machine greatly, also reduced both housings separately, reduced cost, had simple in structure, easy for installation, characteristics such as reliability height.
In addition, when both work at the same time, the DC-DC transducer can directly be exported the 12V low tension and supply with onboard charger in power module, the vehicle-mounted charge machine also can directly be exported high-tension electricity and supply with the DC-DC transducer in power module, be that both directly carry out the interchange of signal and energy in inside, the line loss that traditional discrete device brings and the radiation conducted interference of generation have been avoided, strengthened the interference free performance of system, the conversion because high-pressure section flows between power module inside as much as possible simultaneously, reduced the length of high-tension cable, reduced the insulation property requirement, strengthened the fail safe of high-pressure system when charging, make contribution for car load safety, more can satisfy harsh day by day safety regulations.
Further, the shared control module of circuit board and the fault detection module of the circuit board of described DC-DC transducer and vehicle-mounted charge machine, thus both control units is integrated, further reduce integral vehicle cost, reduce volume, strengthen integrated level and system reliability.
Specifically, described housing comprises the pedestal of upper shell and bottom, and the circuit board of the circuit board of described DC-DC transducer and vehicle-mounted charge machine is fixed on the pedestal, and described temperature sensor is fixed on the upper shell, and described upper shell is fixed by bolt and pedestal.When producing, at first the circuit board of DC-DC transducer and the circuit board of vehicle-mounted charge machine are fixed on the pedestal, and temperature sensor is fixed on the upper shell, utilize the plug-in type wire harness that the circuit board of DC-DC transducer, the circuit board of vehicle-mounted charge machine are connected with temperature sensor then, at last upper shell is fixed by bolt and pedestal, convenient for production, and can not cause the circuit board of DC-DC transducer and the circuit board of vehicle-mounted charge machine in installation process, to damage.
Further, be convenient heat radiation, guarantee that the temperature in the housing is unlikely to too high, the outside of described upper shell is equipped with fin, and described upper shell is equipped with radiator fan.Operating characteristic according to DC-DC transducer and onboard charger, vehicle-mounted charge machine and DC-DC transducer generally can not worked simultaneously, when perhaps working simultaneously, the DC-DC converter power is very low, therefore when work, DC-DC transducer and the shared radiator fan of vehicle-mounted charge machine dispel the heat and can meet the demands, and do not need to have saved a cover radiator system for DC-DC transducer and the independent respectively design radiator of vehicle-mounted charge machine.
Used for electric vehicle integrated electric source module of the present utility model is according to the operating characteristic of DC-DC transducer and vehicle-mounted charge machine, both are become one, common sparing control circuit, housing and cooling system, reduced overall volume, be easy to arrange, improve EMC performance, fail safe and the stability of system simultaneously, reduced cost.
