Problems solved by technology

In particular, the current electric vehicles generally supplement the energy supply by charging at charging stations, but due to the limited number of charging stations, it is not very convenient to charge electric vehicles, which brings inconvenience to the use of electric vehicles.
[0003] In addition, due to the impact of the driving conditions or usage habits of the electric vehicle, the battery manager will have certain errors in the calculation of the mileage of the electric vehicle, so the battery may be insufficient or exhausted before reaching the destination, causing the electric vehicle Impossible to move, thereby causing trouble and inconvenience to the user

Abstract

The invention provides a system for mutual charging of electric vehicles. The system comprises a first electric vehicle, a second electric vehicle and a charging connector, and each of the first electric vehicle and the second electric vehicle comprises a power battery, a battery manager, an energy conversion control device and a charging and discharging socket, wherein the energy conversion control device comprises a three-level bidirectional DC / AC module, a charging and discharging control module and a controller module. The charging connector is connected between the first electric vehicle and the second electric vehicle. When the first electric vehicle enters a discharging mode, the second electric vehicle enters a second charging mode, so that the first electric vehicle can charge the second electric vehicle by the charging connector. By the system for mutually charging the electric vehicles, mutual charging of the electric vehicles is realized. In addition, by the aid of the three-level control, DC-DC modules are reduced, high-power charging is realized, charging efficiency is high and charging time is short. The invention further provides the charging connector.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a mutual charging system for electric vehicles and a charging connector. Background technique [0002] With the development of science and technology, environmentally friendly and energy-saving electric vehicles are playing the role of replacing fuel vehicles. However, the popularization of electric vehicles still faces some problems. In particular, current electric vehicles generally supplement energy supply by charging at charging stations, but due to the limited number of charging stations, it is not very convenient to charge electric vehicles, thereby causing inconvenience to the use of electric vehicles. [0003] In addition, due to the impact of the driving conditions or usage habits of the electric vehicle, the battery manager will have certain errors in the calculation of the mileage of the electric vehicle, so the battery may be insufficient or exhausted before...
