Between collecting system and battery modules, to be convenient for changing.
Battery analog module includes DC voltage divider circuit and multiple data acquisition interfaces, DC voltage divider circuit include multiple
The total voltage of access is divided into decile monomer voltage by voltage node, DC voltage divider circuit, and voltage node and monomer voltage are one by one
It is corresponding.Data acquisition interface is corresponded with voltage node, and each data acquisition interface passes through a switch and corresponding voltage section
Point series connection, each switch composition variable connector selection circuit.Acquisition module connects each data acquisition interface respectively.
In this way, by controlling each on off state in variable connector selection circuit, simulated battery group can be controlled in groups
String number controls the collected sampled voltage of acquisition module, sampled voltage is the integral multiple of monomer voltage, specifically, sampling electricity
Press the product for monomer voltage and closure switch quantity.In present embodiment, by for controlling the monomer voltage effectively acquired
Number, can be adjusted the total voltage value of acquisition, ensure the flexibility of simulated battery group.In present embodiment, data acquisition connects
Fuse is in series between mouth and switch, each fuse forms fuse protection circuit.It is each to be conducive to protection for the color index of Shanghai bourse of fuse
The safety of monomer voltage Acquisition Circuit.
In present embodiment, the total voltage size of DC voltage divider circuit access is adjusted.Specifically, in DC voltage divider circuit
Access the adjustable DC power supply for exporting total voltage.In this way, the size of each monomer voltage can be adjusted further, expand simulation electricity
The simulation context of pond group
In present embodiment, acquisition module uses BMS acquisition systems.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
