It shown in the accompanying drawing 2 workflow diagram of a kind of embodiment of the utility model.The course of work of this embodiment comprises:
Step S201: the network load judging unit reads network load information;
The network load judging unit reads network load information; The monitoring network load changes for guaranteeing that the grid balance sound and stable operation is most important: because power supply level remained unchanged in the regular period; When electricity consumption level surpasses power supply capacity; Instrument possibly occur burning, damage grid equipment, the equivalent risk that trips unusually, the battery capacity of electric vehicle is huge, will increase above-mentioned risk greatly in case a plurality of rechargeable batteries are charged simultaneously; When electricity consumption level significantly was lower than power supply capacity, because electric energy can't global storage, unnecessary electric energy can not effectively utilize, and caused waste, in case a plurality of rechargeable batteries of charging stop charging simultaneously, electricity consumption level will descend rapidly, and utilization rate of electrical decreases.
Step S202: judge whether this network load reaches pre-set threshold value, if, then send corresponding early warning signal to the charging master control system, get into step S202; If, then do not return step S201;
As stated, consider that the charging master control system charges normal in the process rechargeable battery through charhing unit from the angle of power grid security, efficient operation; Provide the load level of the electrical network of electric energy can not be low excessively to charhing unit, must be on preset minimum threshold values, can not be too high; Must establish under the threshold values at maximum prefetch, even according to actual needs, the pre-set threshold value of a plurality of gradients can be arranged; The corresponding a kind of early warning signal of each threshold values if the network load level reaches some pre-set threshold value, then sends corresponding early warning signal to the charging master control system; Regulate the charge condition of a plurality of charhing units by master control system, to adapt to the needs of network load stable operation; Corresponding relation between early warning signal and the pre-set threshold value can be provided with according to the statistics of historical charge condition, is provided with after also can taking into full account the actual conditions of rechargeable battery self electric energy number; In the practical application, to the battery of the electric vehicle of charging station or charging pile charging some electric energy still, the electric weight that needs during charging is less, at this moment can turn down corresponding pre-set threshold value.
Step S203: the charging master control system obtains charging load overall control information according to said early warning signal inquiry preset charged load overall control table; So that use this charging load overall control information to generate power allocation information, and this power allocation information passed to corresponding charhing unit respectively according to preset rules; Said preset charged load overall control table is preserved said early warning signal and charging load overall control information, and said early warning signal is corresponding one by one with charging load overall control information;
Preset charged load overall control table can be set charging load overall control information according to the historical charge condition of this charging system, and these information are corresponding with early warning signal; After the charging master control system receives early warning signal; Promptly inquire about this preset charged load overall control table load overall control information of being charged accordingly; This charging load overall control information is the total amount of the charge power of all charhing units of linking to each other with the charging master control system; If early warning signal is " limit for height " type early warning signal, represent that then the charge power summation of all charhing units can not surpass above-mentioned total amount; If early warning signal is " limitting low " type early warning signal, represent that then the charge power summation of all charhing units can not be lower than above-mentioned total amount; The charging master control system obtains after the charging load overall control information according to this information according to preset rules production power division table, and the power information of distributing is sent corresponding charhing unit;
Step S204: after charhing unit receives said power information, this power allocation information is modulated, and the power information after will modulating passes to vehicle-mounted charging device;
