Abstract

The invention provides a vehicle-mounted double-motor power take-off power supply system and method. The system comprises a first generator, a second generator and a control unit, wherein the first generator is installed in an engine bin, connected with a vehicle engine and driven by the vehicle engine to run and generate electricity; the second generator is installed on a vehicle power take-off opening, connected with a vehicle gearbox and driven by the vehicle gearbox to run and generate electricity; and the control unit is connected with the first generator and the second generator through a cable and controls output power of the first generator and the second generator. According to the vehicle-mounted double-motor power take-off power supply system, the power take-off generators of different power are installed in the vehicle engine bin and on the power take-off opening respectively and controlled simultaneously by the same control unit, so that the working requirements of vehicles on different power utilization working conditions are met, the power of the whole system is improved, the efficiency is improved, the loss is reduced, and the high-power power utilization requirements of light or small vehicles are met.

Description

technical field [0001] The invention relates to the field of vehicle-mounted power for motor vehicles, in particular to a vehicle-mounted dual-motor power take-off power supply system and method, which are applicable to the situation where the vehicle has various power consumption requirements. Background technique [0002] With the continuous development of society, the demand for special vehicles such as ambulance and emergency satellite communication is increasing; in recent years, the demand for various functions of special vehicles has gradually increased, and more and more high-power electrical equipment has been applied to these special vehicles superior. As the vehicle's demand for electric power increases, the demand for system power of the on-board power generation system is also increasing. [0003] However, due to the limited space of the vehicle itself, when a single set of alternator is installed, the maximum power of the system is usually lower than 12kW. If ...
