Abstract
The invention discloses an auxiliary power system for electricity generation of a hybrid vehicle, comprising an engine, a rotating speed sensor, a generator, a rectifier, a power battery, a generating control unit (GCU), an engine ECU, a relay, a starter, a water circulating pump, a water circulating fan, a safety relay, an oil pump relay and an oil pump, wherein the engine is mechanically connected with the generator which supplies power for the power battery; the engine and the generator are commonly controlled by the engine ECU and the generating control unit (GCU); and the generating control unit comprises an electronic accelerator for waking the engine ECU, starting the engine to enter the idle and controlling the ECU, a circular water pump of the generator, a cooling fan and other control parts. The system can meet the energy demand of the finished vehicle, supplement energy for the power battery, increase the driving range of the vehicle, prolong the service life of a power battery pack and achieve the aims of reducing energy consumption, discharging the finished vehicle, improving the dynamic response of the finished vehicle, weakening the noise vibration and the like.
Description
technical field [0001] The invention relates to a component system of a hybrid vehicle, in particular to an auxiliary power system for providing vehicle-mounted power generation for hybrid and pure electric vehicles to increase driving range and prolong the service life of power battery packs. Background technique [0002] Due to the immaturity of power battery technology and control technology, pure electric vehicles still have problems such as high energy consumption and short driving range, which restrict the popularization and application of electric vehicles. In addition to the charging mode (plug in), an on-board auxiliary power generation system solution can also be used to meet the energy demand of the vehicle and to supplement energy for the power battery. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle-mounted auxiliary power generation system for hybrid vehicles to meet the energy demand of the vehicle and suppleme...
