The current trend in the loop where charging control circuit control charge-discharge modules.When charge switch circuit is in blocking During state, place loop is off-state;When charge switch circuit is in the conduction state, place loop due to charging direction The effect of the one-way conduction circuit of one-way conduction, loop current direction can only be the direction charged to charge-discharge modules.Therefore work as When charge switch circuit in the presence of the loop where the charge-discharge modules of at least two parallel connections is conducting state, it is to avoid two The possibility of the mutual discharge and recharge of charge-discharge modules, so as to allow at least two groups charge-discharge modules to there is capacity volume variance and voltage difference It is different, will not mutually discharge and recharge.
Also include main control module, be connected with voltage monitoring module and charge switch circuit respectively.Main control module is received The detection voltage of voltage detection module, and control the conducting and blocking of charge switch circuit.The main control module can be one Individual total main control module, receives the detection voltage of each voltage detection module, and conducting to each charge switch circuit and Blocking is controlled.The main control module can also have multiple, loop one master of correspondence where each charge-discharge modules Control module.
The charge-discharge modules include charge-discharge battery;The charge-discharge battery is physical battery and/or chemical cell.Institute State charge-discharge modules including but not limited to physical battery or chemical cell.
The physical battery is ultracapacitor and/or flying wheel battery.Described physical battery includes but is not limited to super electricity Container and/or flying wheel battery.
The chemical cell is one or more in lead-acid accumulator, lithium ion battery, Ni-MH battery and sodium-sulphur battery Combination.Described chemical cell includes but is not limited to lead-acid accumulator, lithium ion battery, Ni-MH battery and sodium-sulphur battery.
