Abstract

The invention provides a power system of a compound energy electro-vehicle, comprising a compound power supply controlling machine box, a main power supply connected with the power supply controlling machine box, a solar energy photovoltaic cell and a super capacitor module set, wherein, the output end of the compound power supply controlling machine box is connected with a motor driving controlling module and an assistant device, and the other end of the motor driving controlling module is connected with a motor; a hardware main circuit and a control circuit which are mutually connected are arranged in the compound power supply controlling machine box; the hardware main circuit is connected with the solar energy photovoltaic cell via an unidirectional DC / DC converter and is connected with the super capacitor module set via a bidirectional DC / DC converter; the input end of a microprocessor in the control circuit is connected with a temperature detecting module, a current detecting module and a pressure detecting module via a signal conditioning circuit, and the output end is connected with the motor driving circuit and an assistant device potentiometer via an optocoupler isolation circuit. The invention can better improve the acceleration performance and climbing performance of a vehicle, reduce heavy current discharging time of the main power supply and avoid the main power supply from damage and reduction of volume.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power supplies, in particular to a power supply system for hybrid energy electric vehicles. Background technique [0002] An important factor that restricts the wide application of electric vehicles is their driving range. Under the background that the country is vigorously advocating the development of new energy vehicles and electric vehicles, with the rapid development of solar photovoltaic battery technology, making full use of new energy such as solar batteries, Using regenerative braking energy to increase the driving range of electric vehicles has significant social value and economic benefits. Many test vehicles at home and abroad have realized new electric vehicles that use solar energy alone as a supplementary energy source or recover braking energy alone. [0003] And the main shortcoming of above-mentioned scheme is exactly can frequently charge and discharge to main power su...
