Control circuit uses MUC controllers 21, the I/O port with the input of door 22 and AC relay 23 and MCU controllers
Connection, the output end of optical coupling isolation circuit 27 are connected with MCU controller inputs.AC relay 23 is using twin coil control magnetic
Freeze mode relay, the closed and disconnected of magnetic freeze mode relay by closure high level pulse and disconnect high level pulse control respectively
System, logic control circuit is simple, the reliability of strengthening system；Over-current signal is only used as the disconnection of the control relay of MCU controllers 21
The enable signal of signal, logic control is disconnected without directly participating in relay, be also not involved in the closure control of relay, this can be with
The interference free performance of strengthening system；Even if the unexpected power down of control system, the relay in closure state are still remained closed, disappeared
Except the situation that belt current disconnects, and relay line bag need not be powered for a long time, reduce power consumption, extend service life.
MCU controllers are communicated by RS485 and charging pile master controller, and reception charging pile main frame is opened shut-off relay and referred to
Order and the voltage x current value of corresponding charging power modules, when there is logic error, fault message is transmitted to charging pile main frame.This reality
The dial-up address switch 29 that the control circuit of example also includes being connected with MCU controllers 21 is applied, dial-up address switch 29 is used for work(
The address distribution corresponding with the address of charging power modules 1 of rate distribution board 2.
The present invention replaces D.C. contactor using AC relay 23, to realize power dividing function.Add in circuit
Protection circuit is disconnected, when the electric current of AC relay 23 is more than given threshold, AC relay 23 can not disconnect；Only work as stream
When crossing the electric current of AC relay 23 and being less than the threshold value, AC relay 23 could respond open command, so as to avoid exchange after
Electrical equipment disconnects in belt current and produces big electric arc, influences the life-span of relay and needs MCU controllers and charging pile main-machine communication,
The voltage x current value that charging pile main frame opens the instruction of shut-off relay and corresponding charging power modules is received, logic error occurs
When, transmit fault message to main frame.
As shown in figure 1, the corresponding one piece of power distribution board of each charging power modules, by address toggle switch by power
Distribute the address of board and the address of charging power modules to correspond, all power distribution boards are by RS485 buses with filling
The master controller of electric stake is connected, by sending instructions under master controller, meanwhile, the MCU controllers 21 of power distribution board be also required to
The master controller of charging pile sends status signal, controls charging gun to charge by controlling the break-make of D.C. contactor.
As shown in Fig. 2 the master controller of charging pile can learn the voltage of each charging power modules 1 by CAN communication
Current information, and these information are sent respectively to corresponding power distribution board 2.Meanwhile every piece of card of power distribution plate 2 can
Over-current state signal is collected, when the over-current state collected is low level, and corresponding power module 1 is in charged state,
Then there is voltage x current output, be considered as normal charging condition, now the normal work of AC relay 1；When the power module 1 collected
In charged state, there is voltage x current output, and when electric current is over-current state, then it represents that protection circuit has showed failure, now work(
It is closure state that MCU controllers 21 in rate distribution board 2, which control AC relay 23, and uploads fault-signal, makes main control
Plate gives corresponding charging power modules 1 to send shutdown command, after the shutdown of corresponding power module, could disconnect AC relay；If
Charging power modules 1 are closed, but over-current state is low, then protection circuit breaks down, and should upload fault-signal.
MCU controllers 21 close control logic：Main frame to each piece of power distribution board send AC relay closure with
Open command, when the instruction requirement received is closed at two group relays, or a group relay is also not turned off, and is received
The instruction of another group relay is closed, close command should not be performed, and mistake is reported to master board.MCU closes control logic
Flow chart is as shown in Figure 3.
MCU disconnects logic control：If corresponding power module is in charged state, charging power modules have voltage x current defeated
Go out, and electric current is more than protective current threshold value, but the over-current state signal inputted is false, expression flows through current divider electric current and is less than protection
Current threshold, then illustrate that failure occur in signal conditioning circuit or comparison circuit, can not now disconnect relay, and upload event
Hinder signal, allow master board to send shutdown command to corresponding power module, after the shutdown of corresponding power module, relay could be disconnected
Device.It is as shown in Figure 4 that MCU disconnects control logic flow chart.
AC relay 23 closes protection philosophy：As shown in Fig. 2 four group relays add MUX 24 so that four
Group relay can only at most have 1 group of closure, can so ensure in more cars while when charging, will not between car and the battery of car
Connect, ensure electrical isolation.When AC relay 23 is in closure charged state, the electric current for flowing through AC relay 23 will be logical
Current sampling resistor in overprotection circuit is converted into voltage, by protection circuit output overcurrent protection signal.Work as sample rate current
During more than current threshold, overcurrent protection output is high level, represents in guard mode is disconnected, after light-coupled isolation, shields
Signal is 0, will shield the disconnection control signal of all AC relays 23, now, if MCU controllers 21 are interfered, provides
The disconnection control signal of mistake, due to the presence of shielded signal, the mistake that AC relay 23 does not respond to MCU controllers 21 is broken
Instruction is opened, so can guarantee that AC relay 23 will not disconnect in the case of high current, ensures that AC relay 23 is safe and reliable
Work.When sample rate current is less than current threshold, overcurrent protection signal is in guard mode, the signal do not pass through light-coupled isolation
Afterwards, be sent in MUC controllers 21, the disconnection of AC relay 23 is controlled by MCU controllers 21, when MCU controllers 21 by
When interference provides open command, AC relay 23 disconnects, and due to being that low current disconnects, will not produce danger to AC relay 23
Evil.In the present embodiment, the circuit current sampling resistor of selection can not be too big, because needing to flow through big charging electricity when charging normal
Stream, resistance too conference cause power consumption too big；Impedance simultaneously again can not be too small, otherwise for low current rotection thresholds, sampling
Voltage can be very small, and this input offset voltage to amplifier requires too high.When control system accident power-off, and charger is normal
Work and do not have enough time shutting down, while pipette tips heavy DC contactor also do not have enough time disconnect when, the relay of closure
Due to magnetic retention performance, it can be kept closed, guarantee is not in the situation that high current disconnects.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
