Abstract

A standby energy source system for electric vehicles consists of a gasoline generator set, a transfer switch and a DC (direct current) output device, wherein the DC output device is a charger or a transformation and rectifier-filter circuit. The standby energy source system can provide an auxiliary power supply for the electric vehicles. The standby energy source system can drive the electric vehicles by directly charging a power battery through the charger, or by generating a low-voltage DC power (15 V to 30 V) through the transformation and rectifier-filter circuit, and directly supplying the power to a motor system through a controller. Therefore, the provision of the standby energy source system is one of the effective ways to solve the problem that the electric vehicle cannot run during driving due to low battery capacity.

Description

technical field [0001] The invention relates to an energy system of an electric vehicle, in particular to an internal combustion generator set as an auxiliary energy system of the electric vehicle. Background technique [0002] The patent with the application number 200520010521.1 and the utility model name "a gasoline generator set" discloses a gasoline generator set with AC and DC output functions. Including engine, stator and rotor, air filter, muffler, fuel tank and control panel, the fuel tank is supported on the rear bracket of the stator and rotor through the support plate, and the DC socket, rectifier bridge and DC overcurrent protection are installed on the support plate device. The gasoline generator set solves the crowded situation of the electrical components on the control panel, so that the electrical components on the control panel can be arranged reasonably, which is conducive to the heat dissipation of the electrical components, and eliminates the existence...
