Embodiment 1

[0035] An embodiment of the present invention provides a charging power supply for electric vehicles, see figure 1 , the charging power source includes:

[0036] Two DC output modules 1 and 2 are respectively connected to the output terminal VOUT of the power supply, and are used to output a DC power supply for external power supply; and,

[0037] A switch module 3 is connected to the two DC output modules 1, 2 and the power supply output terminal VOUT respectively, and is used to switch the two DC output modules 1, 2 on or off according to the type of the electric vehicle. 2, so that the two DC output modules 1, 2 can charge the electric vehicle through the corresponding connection relationship.

[0038] It should be noted that the two DC output modules 1 and 2 respectively output DC power. According to the type of electric vehicle, the switch module 3 connected to the two DC output modules 1 and 2 switches the two DC outputs by turning on or off. The modules 1 and 2 are co...

Embodiment 2

[0063] An embodiment of the present invention provides a method for charging an electric vehicle using the charging power source in the above embodiment, see figure 2 ,include:

[0064] S1. Obtain the type of electric vehicle;

[0065] S2. According to the type of the electric vehicle, switch the connection relationship between the two DC output modules, so that the two DC output modules charge the electric vehicle through the corresponding connection relationship.

[0066] It should be noted that when the type of electric vehicle is a minibus or a car, the control switch module is turned on, and the connection relationship between the two DC output modules is switched to parallel connection, so that the DC power output by the two DC output modules is connected in parallel to The electric vehicle is charged; when the type of the electric vehicle is a bus, the control switch module is turned off, and the connection relationship between the two DC output modules is switched to...

Abstract

The invention discloses a charging power supply of an electric vehicle and a charging method of the electric vehicle. The charging power supply comprises two direct current output modules and a switch module, wherein the two direct current output modules are connected with a power output end and used for outputting direct current to supply power externally, and the switch module is connected with the two direct current output modules and the power output end and used for switching the connection relation between the two direct current output modules through connection or disconnection, so that the two direct current output modules can supply power externally according to different connection relations. The application range of the electric vehicle can be broadened, and the charging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a charging power supply for electric vehicles and a charging method for electric vehicles. Background technique [0002] Existing GM electric vehicles include buses, minibuses and sedans. Among them, the voltage of the power battery of a bus is generally around 600V, while the voltage of the power battery of a minibus and a car is generally around 400V. Therefore, there are currently two types of charging power sources on the market: those used for fast charging of minibuses and cars Charging system with low voltage output, generally the output voltage of this system is 450-200V, its output current is constant, and the maximum power is output only at the highest output voltage, and the output power is small at low voltage; it meets the needs of the bus. The high-voltage output charging system used for charging generally has an output voltage of 750-350V, and the output cu...
