Therefore, the charging gun can output charging power by combining the load condition and the charging demand information of the system. The power adjusting controller P _ JK is preferably connected with the power module and the terminal controller through a CAN bus respectively.
The power modules preferably adopt 8 groups (respectively, M1 to M8), the maximum output power of each power module is preferably 15KW × N or 20KW × N, N is an integer not less than 1, such as 1, 2, 3, and the like, and the corresponding maximum output power is 15 or 20KW, 30 or 40KW, 45 or 60KW, and the like. And, it is preferable to select a power module with an output voltage adjustable between DC150V and DC750V in the prior art, so as to be suitable for charging various electric vehicles. 8 power modules correspond 8 rifle (1 CDQ to 8CDQ respectively), 8 direct current bus relay (1KM to 8KM respectively) and 8 terminal controller (ZK 1 to ZK8 respectively), and the power regulation relay who connects between the power cord is 28 totally (1KM2 to 7KM8 respectively).
By taking the configuration of 8 power modules, and the maximum output power of each power module is 20KW as an example, the working principle of the embodiment of the present invention is explained as follows:
1. When each charging gun is idle, all power modules are in a standby state, and the direct current bus relay (1KM to 8KM) and the power automatic regulating relay (1KM2 to 7KM8) are in an off state.
2. When one charging gun (such as 1CDQ) is connected with the electric automobile, the terminal controller ZK1 receives power demand information sent by the electric automobile BMS, and the terminal controller ZK1 sends the demand information to the power regulation controller P _ JK; the power regulation controller P _ JK controls a corresponding direct current bus relay to be attracted according to the maximum capacity and the residual power of the current system, the charging gun 1CDQ is kept charged currently, meanwhile, whether the maximum output power of the power module M1 meets the power required by the vehicle is determined, if the maximum output power of the power module M1 meets the power required by the vehicle, when the charging requirement is smaller than 20KW, the power regulation controller P _ JK controls the power module to directly output charging voltage and current matched with the charging requirement information, the power regulation controller P _ JK does not perform any action, if the maximum output power of the power module P _ JK does not meet the charging requirement, when the charging requirement is larger than 20KW, the power regulation controller P _ JK switches any one or more of the power regulation relays 1KM2, 1KM3, 1KM4, 1KM5, 1KM6, 1KM7 or 1KM8, and calls other power modules until the current vehicle requirement is met.
3. If other charging guns (such as 2CDQ) are connected with the electric automobile in the charging process of the charging gun 1CDQ, power demand information sent by the electric automobile BMS is received, and the terminal controller ZK2 sends the demand information to the power regulation controller P _ JK; the power regulation controller P _ JK detects whether the current power module M2 is occupied by 1CDQ or not, if not, the power regulation controller P _ JK keeps charging the current charging gun 2CDQ according to the maximum capacity and the residual power of the current system, and simultaneously determines whether the maximum output power of the power module M2 meets the power required by the vehicle or not, if so, the power regulation controller P _ JK does not perform any action, if not, the power regulation controller P _ JK switches any of the 2KM3, the 2KM4, the 2KM5, the 2KM6, the 2KM7 or the 2KM8 when the charging requirement is more than 20KW so as to achieve the current vehicle requirement; if the power adjusting controller P _ JK is occupied, the power adjusting controller P _ JK adjusts the relay 1KM2 with which the current M2 power module is connected to be disconnected, and controls to call one of other unused power modules M3, M4, M5, M6, M7 or M8 to the charging gun 1CDQ, so that the vehicle requirement of the charging gun 1CDQ is maintained.
4. When all the power modules (M1-M8) are occupied and a charging gun (such as 8CDQ) is not used currently, when the charging gun 8CDQ is connected with the electric automobile, the terminal controller ZK8 receives power demand information sent by the electric automobile BMS, and the charging terminal ZK8 sends the demand information to the power regulation controller P _ JK; the power regulation controller P _ JK detects that the current power module M8 is occupied, and the power regulation controller P _ JK regulates the current power module M8 to distribute the power regulation relay connected with the charging gun to be disconnected, so that the power module M8 is kept to have 20KW of power for the charging gun 8CDQ to use, and all the charging guns can be used.
5. In the charging process that the power modules (M1-M8) are occupied, if the charging requirement of a charging gun is reduced, for example, the charging requirement of the charging gun 1CDQ is reduced from 60KW to 40KW, the power regulation controller P _ JK controls the corresponding power modules to quit working; at this time, if there are other charging guns failing to meet the charging requirement of the connected vehicle, the power regulation controller P _ JK supplies the withdrawn power module to the other charging guns for charging based on the principle of first-come-first-charge being satisfied preferentially, so as to regulate to each dynamic requirement charging gun and keep the maximum utilization of the whole system. When the charging gun starts charging again, the power regulation controller P _ JK automatically enables the power module to exit from the assigned charging gun, and the use of the free charging gun is kept.
