In, the magnitude of voltage of two signal output part outputs per paths is obtained using CSC, it is then, defeated according to two signal output parts
The difference of the magnitude of voltage for going out obtains the magnitude of voltage of the passage.
Hereinafter, illustrate by taking the voltage of the battery core simulated by the passage 1 in the battery simulation system shown in Fig. 3 as an example.
The magnitude of voltage of the battery core simulated for passage 1, two wires that CSC1 can pass through in C1 distinguish the two of 1 two ends of Acquisition channel
The magnitude of voltage exported by individual signal output part, if the magnitude of voltage of two signal output part outputs of the passage for getting 1 is respectively
V0 and V1, then the magnitude of voltage of the battery core simulated by passage 1 be V1-V0.Thus, the principle of battery core voltage is gathered using difference,

Row is illustrated.
For example, if BCS needs the set of cells of simulation to be made up of 8*N battery core, the S2 in Fig. 3 and S2 ' can be closed,
It is N-1 that the number of CSC1 can be the number of 1, CSC2, and specifically, 1～passage of passage 8 is used alone by CSC1, CSC1 collections
The fluctuation of the magnitude of voltage for arriving is less, can serve as balanced test, and 9～passage of passage 16 is multiplexed by remaining N-1 CSC.Such as
This so that CSC with normal work, and can rationally apply all passages in BCS, as N number of CSC is arranged at the difference of BCS
Side, the distance in the embodiment of the present invention apart from a BCS farthest CSC and BCS are greatly shortened compared to prior art, because
This, the partial pressure of resistance is used also to be weakened, and the fluctuation of the magnitude of voltage that the CSC is collected reduces, the stability of data compared to
Prior art is highly improved, it is to avoid as electric resistance partial pressure effect apart from BCS farthest CSC occurs in prior art
Gathered data inaccurate situation, and then, it is to avoid situation in a balanced way is opened in opening by mistake for thus causing.
Or, and for example, if BCS needs the set of cells of simulation to be made up of 12*N battery core, can by the S1 in Fig. 3,
S6 and S6 ' closures, the number of CSC1 can be N-1 for the number of 1, CSC2, and specifically, 1～passage of passage 4 is individually made by CSC1
With the fluctuation of the magnitude of voltage that CSC1 is collected is less, can serve as balanced test, and 5～passage of passage 12 is common by N number of CSC
With 13～passage of passage 16 is used by remaining N-1 CSC.So so that all CSC with normal work, and can rationally be applied
All passages in BCS, as N number of CSC is arranged at the not homonymy of BCS, apart from farthest one of BCS in the embodiment of the present invention
The distance of CSC and BCS is greatly shortened compared to prior art, therefore, the partial pressure of resistance is used also to be weakened, the CSC
The fluctuation of the magnitude of voltage for collecting reduces, the stability of data is highly improved compared to prior art, it is to avoid existing skill
Due to the inaccurate situation of gathered data that this occurs apart from the electric resistance partial pressure effect of BCS farthest CSC in art, and then, it is to avoid
Thus situation in a balanced way is opened in opening by mistake for causing.
Or, and for example, if BCS needs the set of cells of simulation to be made up of 12*N+9*I battery core, can be by Fig. 3
S1 and S6 closures, the number of CSC1 can be N-1 for the number of 1, CSC2, and specifically, 1～passage of passage 4 is individually made by CSC1
With the fluctuation of the magnitude of voltage that CSC1 is collected is less, can serve as balanced test, and 5～passage of passage 12 is N+I CSC institute
Share, 13～passage of passage 16 is used by remaining N+I-1 CSC.So so that all CSC can be with normal work, and rationally
The all passages in BCS are applied, it is as N number of CSC is arranged at the not homonymy of BCS, farthest apart from BCS in the embodiment of the present invention
The distance of one CSC and BCS is greatly shortened compared to prior art, therefore, the partial pressure of resistance is used also to be weakened, should
The fluctuation of the magnitude of voltage that CSC is collected reduces, the stability of its data is highly improved compared to prior art, it is to avoid existing
There is the inaccurate situation of gathered data occurred apart from electric resistance partial pressure effect of BCS farthest CSC due to this in technology, and then,
Avoid opening by mistake of thus causing and open situation in a balanced way.
A technical scheme in this utility model has the advantages that：
1), in the embodiment of the present invention, N number of battery monitoring unit is arranged on into the not homonymy of battery simulation device, thus, being directed to
The not homonymy with other CSC, distance in the embodiment of the present invention can be arranged on apart from a farthest CSC of BCS in prior art
The distance of a BCS farthest CSC and BCS is greatly shortened compared to prior art, therefore, the partial pressure of resistance is used also to be obtained
To weaken, the fluctuation of the magnitude of voltage that the CSC is collected reduces, and the stability of its data obtains larger carrying compared to prior art
Rise, it is to avoid as this is larger apart from the gathered data fluctuation that the electric resistance partial pressure effect of BCS farthest CSC occurs in prior art
Situation, and then, it is to avoid when CSC carries out equalization operation according to the BCS data for collecting, caused due to data fluctuations and opened by mistake
Open situation in a balanced way.
