Embodiment Construction
[0017] Such as image 3 As shown, the system of the present invention has N rectifier modules and M output charging ports, and both N and M are two or more. The rectifier modules are divided into two categories, which are called fixed groups and switching groups. The modules in each group do not have to be placed together, and can be flexibly placed according to system requirements. The output of the fixed group of modules is connected to each output charging port separately, without a switch in the middle, and the number of modules connected to each output charging port is not necessarily the same. There is a group of two-way controllable electronic switch devices between the output positive and negative poles of each module of the switching group (several modules can also be connected in parallel as one module) and each output charging port. The main control, display and communication unit modules are respectively connected to each module and the output control switching ...

The invention discloses a one-machine-and-multiple-charging electrombile charging system and method which are used for electrombile charging. The one-machine-and-multiple-charging electrombile charging system and method are characterized in that a rectifying module is divided into a fixing group and a switching group, wherein the output end of each module of the fixing group is respectively connected with each output charging port, and a group of bidirectional controllable electronic switches is connected between the positive pole and the negative pole of the output end of each module of the switching group and each output charging port; the number of opened modules of the switching group is simultaneously controlled by a master control unit according to the size of the current capable of being output by each module; and when output voltage of the opened modules rises to be nearly equal to the battery voltage of an electrombile, the output controllable electronic switches of the opened modules of the switching group are simultaneously turned on, and the modules of the fixing group and the modules of the switching group are all connected with a battery to be charged. According to the one-machine-and-multiple-charging electrombile charging system and method, the utilization ratio of the modules is greatly improved, fast charging can be achieved, and requirements of customers for the charging time can be met; and simultaneously the electrombile battery can be charged in customization mode according to requirements of the customers or a battery management system (BMS), and battery service life can be prolonged.
Description
technical field [0001] The invention relates to a charging system for charging electric vehicles. 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 affe...
