Concrete, the technical solution of the utility model specific features is as follows: with reference to Fig. 4 to Fig. 6, for 3 charging terminals:
1. constant power district: constant power district is for meeting the minimum number module needed for the basic charge function of charging terminal, and the DC bus of the corresponding charging terminal of its fixing access, the module in this region does not possess power dynamic assignment function.In embodiment, 1MK1 ~ m, 2MK1 ~ m, 3MK1 ~ m connect DC bus corresponding to 1#, 2#, 3# charging terminal 1, DC bus 2, DC bus 3 respectively.Wherein, the constant power district module number that different terminals is corresponding can not be identical.For corresponding 2 the constant power district 15kW charging modules of three terminals.
2. dynamic power district: dynamic power district is the major part realizing power dynamic assignment, the module in this region by dynamic assignment array switching on DC bus corresponding to different terminals, to realize the dynamic assignment of power.Configure 6 15kW charging modules altogether for dynamic power district, be designated as DMK-1 ~ DMK6 respectively.
3. dynamic assignment array: this part forms primarily of controllable switching device is by the actuator of dynamic power district module switching to the corresponding DC bus of different terminals.High-voltage DC contactor selected by gate-controlled switch device in this example, the every platform charging module in dynamic power district configures 6 D.C. contactors respectively, charging module is exported (+) and drops into DC bus 1 (+), DC bus 2 (+), DC bus 3 (+) respectively, charging module is exported (-) and drops into DC bus 1 (-), DC bus 2 (-), DC bus 3 (-) respectively, drop into two contactor synchronization actions of same section of DC bus (+), (-).
4. matrix controller: its Main Function is the charging module quantity of the demand receiving charging terminal, and control dynamic assignment array by the module switching of requirement on DC bus corresponding to this charging terminal, and this module switching of locking is simultaneously to the function of other DC buss.Primarily of the control unit such as DSP, single-chip microcomputer or PLC composition, by RS485, CAN communication bus and charging terminal communication, and by the D.C. contactor of relay tip control dynamic assignment array deciliter.
5. charging terminal: the interface being charging heap and electric automobile interaction, it receives the charge requirement value that electric automobile sends, and the charging module quantity needed for calculating, notice matrix controller carries out power division, and according to electric automobile demand dynamic conditioning actual output voltage, electric current.In this example, charging terminal is made up of charge controller, man-machine interface, measure and control device, charging inlet etc., and it carries out digital communication with electric automobile, matrix controller, charging module respectively.
In addition, in the embodiment shown in this Fig. 4 to Fig. 6, charging terminal quantity is 3, and corresponding DC bus is 3.The constant power district charging module quantity that every station terminal is corresponding is 2, and dynamic power district module number is 6, and separate unit charging module rated power is 15kW.
When each charging terminal is in idle condition, all charging modules are in holding state, each high-voltage DC contactor in dynamic assignment array is all in off-state, i.e. " all charging modules in dynamic power district all disconnect with each DC bus ", when 2# charging terminal is connected with electric automobile, when the charge power requirements received is 84kW (or voltage, current value), charging terminal is 4 (aggregate demand charging module number is 6) by calculating the charging module quantity that need drop into this section of DC bus again, and is issued to matrix controller.Matrix controller controls 1KM2 (+), 2KM2 (+) in dynamic assignment array automatically, 3KM2 (+), 4KM2 (+) put into DC bus 2 (+), 1KM2 (-), 2KM2 (-) in control dynamic assignment array, 3KM2 (-), 4KM2 (-) put into DC bus 2 (-), and synchronously by the communication bus of module communication line switching to correspondence;
2# charging terminal is by real-time reception electric automobile demand information, and the output power value automatically adjusting each charging module on this section of DC bus is 14kW (or electric current and voltage value), and adjusts it according to the actual output feedack value detected; As electric automobile requirements is adjusted to 78kW, each module output power limit will be automatically 13kW by charging terminal.In charging process as electric automobile requirements be increased to 98kW time, it is 1 that terminal will recalculate required increase module number, and notify matrix controller, 5KM2 (+) in control dynamic assignment array and 5KM2 (-) puts into DC bus 2 (+) and DC bus 2 (-) respectively, and each module power output is adjusted to 14kW by charging terminal.When charging electric vehicle requirements reduces in like manner.
If in the process of 2# charging terminal charging, 3# charging terminal is connected with electric automobile, starts charging.If the charge requirement value that electric automobile sends is 24kW, then matrix controller is without any need for action, and directly utilize two charging modules in constant power district for its charging, it is 12kW that 3# charging terminal controls every platform module power output.If when charging electric vehicle requirements is 33kW, by above-mentioned steps, 6KM3 (+) and 6KM3 (-) is dropped into DC bus 3 (+) and DC bus 3 (-) respectively, 3# charging terminal is 11kW by automatically adjusting each charging module output power value.If when fruit charging electric vehicle requirements is 56kW, because all modules in dynamic power district are assigned, matrix controller is by no longer action, and 3# charging terminal is 15kW by automatically adjusting each charging module power output.As in 3# charging process, 2# charging terminal has charging module to exit, and matrix controller will notify 3# charging terminal, and 3# charging terminal will recalculate and need drop into module number again, and notice matrix controller controls corresponding module and drops into.
After the charging of 2# charging terminal terminates, all charging modules in dynamic power district dropping into this section of DC bus exit by 2# charging terminal notice matrix controller.Now, corresponding in dynamic assignment array gate-controlled switch is off state.Other-end in like manner.
Fig. 1 to Fig. 2 also show the charging method of a kind of dynamic assignment power in the utility model, the method can provide different capacity automatically according to the actual needs of dissimilar electric automobile from dynamic power district, thus both met the charging electric vehicle demand of different stored energy capacitance, different rate of charge, conversion efficiency and the utilance of charging device can be improved again further.
As shown in Figure 1, the charging method of this dynamic assignment power comprises the steps:
S10, each charging terminal to be connected with corresponding electric automobile;
S20, charging terminal receive the charge power demand of electric automobile, and the module gross power in constant power district corresponding with charging terminal for charge power demand are compared;
If S30 charge power demand exceedes the module gross power in constant power district, charging terminal calculates the charging module quantity that need drop into this section of DC bus again, and is issued to matrix controller;
The charging module of requirement in dynamic power district, by required charging module quantity, drops on corresponding DC bus by S40, matrix controller, and synchronously by the communication bus of module communication line switching to correspondence.
As shown in Figure 2, in certain embodiments, the charging method of this dynamic assignment power also can comprise the steps:
S10, each charging terminal to be connected with corresponding electric automobile;
S20, charging terminal receive the charge power demand of electric automobile, and the module gross power in constant power district corresponding with charging terminal for charge power demand are compared;
