Embodiment Construction
[0013] Such as image 3 As shown, the present invention connects N rectifier modules at the three-phase input end, has M output charging ports, M≥2, and a group of two-way controllable Electronic switch device, the output of each rectifier module can be connected to different output charging ports through a bidirectional controllable electronic switch. It is also possible to connect several rectifier modules in parallel as one module. The main control, display and communication unit modules are respectively connected to each rectification module and the output control switching unit module, and the output control switching unit module is connected to the bidirectionally controllable electronic switch device.
[0014] The output of each rectifier module can be connected to different output charging ports through a controllable electronic switch. The rectifier module switching can be switched according to the charging current of the battery being charged. It can be switched acc...

The invention discloses a battery charger capable of charging multiple electric vehicles and a charging method of the battery charger capable of charging multiple electric vehicles. A pair of bi-directional controlled electronic switches is connected between an input anode of each rectification module and an output cathode of each rectification module and a pair of output charging ports. When any one of charging ports is provided with the electric vehicle which needs charging, battery information of the electric vehicle is obtained, the rectification modules start, a main control unit controls the number of the starting rectification modules according to the size of current which each rectification module can output. When the output voltage is almost equal to the voltage of a battery of the electric vehicle, the electric vehicle is charged. When the charging electric quantity gradually increases, the main control unit gradually closes all rectification modules according to the size of the current, and charging is finished. Use rate of each rectification module is improved, a requirement of quick charge is satisfied, and the service life of the battery is improved.
Description
technical field [0001] The invention relates to a charger for charging an electric vehicle. Background technique [0002] At present, the electric vehicle industry is on the rise, and the electric vehicle chargers equipped with it are also developed. However, due to the impact of high price, low battery reliability, and long charging time, it can only be used in a small area. The charging facilities for electric vehicles It is also impossible to carry out large-scale layout, so the range of activities of electric vehicles is greatly limited. It is necessary to increase the large-scale layout of charging facilities in order to promote the large-scale development of electric vehicles. The large-scale layout of charging facilities is also affected by the high investment in charging facilities, the scarcity and high cost of land in urban centers, the lack of large-scale construction of charging stations, the lack of electric vehicles, and the long charging time that affects the ...
