Specific embodiment, the present invention will be described in further detail.It should be appreciated that the specific implementation described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
It is the functional block diagram of the energy-storage system 100 of offer in the embodiment of the present invention referring again to Fig. 1.The energy storage system
System 100 includes multiple battery packs 10, multiple auxiliary reclays 20 and auxiliary reclay control system 30.Specifically, it is described many
Individual battery pack 10 is used to provide electric energy.Described each battery pack 10 includes some cells.The multiple auxiliary reclay 20
Corresponded with the multiple battery pack 10, and be respectively used to disconnection and the closure of the corresponding battery pack 10 of control.
The auxiliary reclay control system 30 includes multiple acquisition modules 310, multiple from control module 320 and a main control module
330.Wherein, the multiple acquisition module 310 is corresponded with the multiple battery pack 10.It is the multiple from control module 320 with
The multiple acquisition module 310 is corresponded.It is to be appreciated that above-mentioned each functional module can be stored in form of software programs
In memory, or the hardware with specific function, for example, burning has the chip of particular software application.
Above-mentioned each functional module is described in detail with reference to Fig. 2.
As shown in Fig. 2 it is the flow chart of feed method in the embodiment of the present invention.It should be noted that, side of the invention
Method is not limited to the order of following step, and in other embodiment, the method for the present invention can only include step as described below
A portion, or part steps therein can be deleted.
Step S01, the multiple acquisition module 310 is respectively used to the state letter of the corresponding battery pack 10 of collection
Cease and send to corresponding from control module 320.
Specifically, after the energy-storage system initial power-on, it is corresponding that the multiple acquisition module 310 starts collection
The status information of the battery pack 10, and the status information of the battery pack 10 that will be collected passes through CAN (Controller
Area Network, controller local area network) bus send to described in corresponding from control module 320.In present embodiment
In, the status information of each battery pack 10 includes voltage, electric current and the temperature of some cells.
Step S02, the multiple shape being respectively used to from control module 320 according to the corresponding described battery pack 10 for receiving
State information judges whether the corresponding battery pack 10 meets closure condition.If the battery pack 10 meets closure condition,
Then enter step S03；If the battery pack 10 is unsatisfactory for closure condition, continue to judge.It is to be appreciated that working as the battery pack
(there is electric leakage hidden danger) when 10 insulation values are too low, be then unsatisfactory for closure condition.
Step S03, it is described each be additionally operable to send request close command to the main control module 330 from control module 320.
Specifically, institute each from control 320 points of module by CAN by request close command send to the master control mould
Block 330.
Step S04, the main control module 330 is used to detect the voltage platform state of the energy-storage system 100, and according to institute
State the current voltage status of energy-storage system 100 send at random close command to sent request close command from control module 320.
Specifically, for example, the main control module 330 is currently received the request closure sent from control module 320 described in 10
Instruction, but according to the voltage status of current system, 5 battery packs can only be closed, and now, the main control module 330 is sent out at random
Send close command to 5 therein from control module.
Step S05, it is described to be additionally operable to receive the close command from control module 320, and controlled according to the close command
Its corresponding described auxiliary reclay 20 is closed.
Step S06, the main control module 330 is additionally operable to judge to have sent the described from control module 320 of request close command
Whether the corresponding auxiliary reclay 20 has closed.If having sent the described from control module 320 institute of request close command
The corresponding auxiliary reclay 20 has been closed, then stop continuing to send close command, and flow terminates；If having sent request to close
The auxiliary reclay 20 corresponding to control module 320 of instruction is closed without all closing, then into step S04, directly
Closed to all auxiliary reclays 20 and completed.
Auxiliary reclay control system 30 provided by the present invention and method, the main control module 330 pass through detecting system
The state of voltage platform, that is, by judging that the ability to bear of Current Voltage of load and circuit is asked to close to have sent at random
Ask close command it is described from control module 320 corresponding to the auxiliary reclay 20, and then cause when the multiple centre after
When electrical equipment 20 is closed at, it is to avoid load or circuit because are burnt out by the impact of instantaneous pressure, it is ensured that the energy storage system
The safely and effectively operation of system 100.
The present invention is not restricted to described in specification and implementation method, therefore for the personnel of familiar field
