The invention discloses a direct-current V2V electric vehicle charging and discharging device and method. The device comprises a direct-current discharging connector connected with a direct-current discharging vehicle, V2V conversion equipment and a direct-current charging conversion connector connected with a direct-current charging vehicle. The direct-current discharging connector comprises a CC1 resistor detection circuit, a CC2 resistor detection circuit, a DC + / DC-loop, an A + / A-loop, an S+ / S-loop, a resistor R2, a resistor R3 and a resistor R4. The V2V conversion equipment comprises a V2V controller, and a DC / DC converter for step-up / step-down, a resistor R1 and a resistor R1', and by adopting the technical scheme, direct current charging and discharging between any two electric vehicles can be carried out by monitoring data parameters of the charging and discharging vehicles and adjusting step-up / step-down; during direct-current charging and discharging, step-up / step-down are regulated and controlled, so that the influence of battery parameters of the storage battery is avoided.
Description
technical field [0001] The invention relates to the technical field of charging and discharging of new energy vehicles, in particular to a DC V2V electric vehicle charging and discharging device and method thereof. Background technique [0002] As an outstanding representative of new energy, electric vehicles have the advantages of environmental protection and energy saving, and are replacing traditional fuel vehicles. [0003] At present, in order to meet the charging and discharging needs of electric vehicles, electric vehicles currently have AC vehicle-to-vehicle charging and discharging functions, but there are relatively few applications for DC vehicle-to-vehicle charging and discharging. The vehicle-to-vehicle charging and discharging solution has been widely used in the field of electric vehicles. The current DC V2V device in the market is a cable with a charging gun head connected to each end. One end of the gun head is connected to the charging vehicle, and the othe...
