A device for mutual charging of electric vehicles

Abstract

The invention relates to the technical field of electric automobile charging, in particular to an electric automobile inter-charging device. The electric automobile inter-charging device comprises an electric automobile A and an electric automobile B, and the electric automobile A and the electric automobile B each comprise a battery connected with a BMS and a charging connection determination C; the electric automobile inter-charging device further comprises a charging conversion device A, a charging conversion device B and a charging connecting device. The charging conversion device A and the charging conversion device B each comprise a charging-discharging main circuit, a signal sampling module, a controller, an IGBT driving module, a CAN module, a charging connection determination D, a human-computer interface, a low-voltage auxiliary power source and a power source module; the charging connecting device comprises a vehicle socket A, a vehicle socket B, a vehicle plug A and a vehicle plug B, wherein the vehicle socket A and the vehicle socket B are arranged on the electric automobile A and the electric automobile B respectively, and the vehicle plug A and the vehicle plug B are arranged on the charging conversion device A and the charging conversion device B respectively. According to the device, each driving vehicle serves as a movable power source, a vehicle-vehicle power supplying device is achieved in a direct-current-alternating-current-power-source-conversion mode, and electric automobiles can be rapidly and conveniently charged in the driving process.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to a device for mutual charging of electric vehicles. Background technique [0002] With the depletion of petrochemical resources and the intensification of global air pollution, the number of automobiles is increasing day by day, which poses severe challenges to traditional internal combustion engine vehicles. Especially in China, where the economy is developing at a high speed, oil consumption and imports continue to rise, which has created unprecedented pressure on the development of the automobile industry, which consumes a lot of fuel. With the development of the times, electric vehicles are more and more likely to replace traditional cars. As a new generation of transportation, electric vehicles have incomparable advantages in terms of energy saving, emission reduction and pollution reduction. However, with the rapid increase in the number of el...

Problems solved by technology

[0003] Traditional charging methods are generally divided into two types: one is to build a large number of charging piles to provide power for cars. As of 2015, there are more than 11,000 charging piles that have been built or are under construction in Wuhan alone. The distribution is uneven, the search time is too long, and the charging is slow. The other is to install a charger under the road to charge the driving car. Although the problem of long search time is solved, the construction cost is relatively high. There are only a few cities in China such as Guangzhou for pilot projects

Therefore, there will be an embarrassing situation in which the battery power of the electric vehicle user is insufficient or even exhausted on the road and cannot move, which brings great inconvenience to the user of the electric vehicle, and also limits the promotion of the electric vehicle to a certain extent.
