S19 is switched for 9 totally；2nd string (the second trunk access 2) has S21-S29 totally 9 switches；3rd string (the 3rd trunk access 3) has
S31-S39 totally 9 switch, outermost two controlled switch of every trunk access connect respectively the trunk access positive terminal and
Negative pole end.The anode and cathode of each battery unit pass through one of a branch controlled switch and corresponding trunk access respectively
Controlled switch is in parallel, such as battery core B is opened by branch controlled switch S1B+ and branch controlled switch S1B- and the first trunk access
It is in parallel to close S12.Namely one end of battery core B positive terminal connecting valves S1B+, one end of negative pole end connecting valve S1B-, S1B+'s is another
One end connects one end that S12 is switched in the first trunk access, and the other end of S1B-, which connects, switchs the another of S12 in the first trunk access
One end；Battery core B is in parallel by branch controlled switch S2B+ and branch controlled switch S2B- and the second trunk channel selector S22.
That is one end of battery core B positive terminals connecting valve S2B+, one end of negative pole end connecting valve S2B-, the other end connection second of S2B+

It crosses branch controlled switch S3B+ and branch controlled switch S3B- and the 3rd trunk channel selector S32 is in parallel.Namely battery core B positive terminals
One end of connecting valve S3B+, one end of negative pole end connecting valve S3B-, the other end of S3B+ connects to be opened in the 3rd trunk access
One end of S32 is closed, the other end of S3B- connects the other end that S32 is switched in the second trunk access.The battery unit (battery core B) and
All branch controlled switch being connected with its both ends form a battery unit branch.Other battery units (battery core A, battery core C
Deng) it is similar with battery core B with the connection mode of the switch in each trunk access, and battery core A, battery core C etc. respectively and with its both ends phase

Both ends connection all branches controlled switch all disconnect, and be closed S12, S22, S32, you can realize battery core B is not accessed it is any
One trunk access.Other battery cores can also be realized by similar fashion and are not connected with any one trunk access.
Design in this way, any one electricity being connected by branch controlled switch with a certain trunk access controlled switch
Pool unit can be arbitrarily moved in the trunk access.
Battery core move mode can be concluded as follows：The branch that battery core is first connected to the trunk access at original place is controlled
Switch disconnects, and the corresponding trunk access controlled switch that branch controlled switch in the trunk access is connected is closed；By purpose
The trunk access controlled switch being connected in trunk access with the battery core disconnects, by battery core and the purpose trunk access to be moved to

The negative pole end of output terminal and the trunk access connects one end of another channel selecting controlled switch, channel selecting choosing
The other end for selecting controlled switch is connected to the cathode output end of corresponding destination channel.If the destination channel of a trunk access has
It is multiple, then structure just now is just repeated, it is cathode output end in the positive terminal of trunk access, negative pole end and destination channel, negative
Pole output terminal increases a channel selecting controlled switch respectively, it is possible to realize that the access that the trunk access can be selective is multiple
Destination channel.As special case, if a certain trunk access is fixed to access a destination channel (the trunk access 1 in such as Fig. 9),
So, the positive terminal of the trunk access and negative pole end there is no need to by channel selecting controlled switch and can directly and passage
Output terminal is connected.
Multichannel energy-storage units described above, which assemble circuits structure, can realize more flexible multi-channel structure,
Such as the selection by docking number of batteries, cell voltage into trunk access, can realize each passage voltage it is identical or
It is different.Such as by 4.9V, three battery series connections of 5.1V, 5V enter in the first trunk access 1, by 5V, three batteries of 5V, 5V
It accesses in the second trunk access 2, and by 4.9V, two battery series connections of 5V enter in the 3rd trunk access, make the electricity of the 3rd 5V
Pond is off, and the number of batteries of three trunk accesses is identical or different at this time, the positive terminal and negative pole end shown it
Between voltage it is also identical or different, be 15V, 15V, 9.4V respectively, voltage is identical or approximate trunk access can pass through parallel connection
Mode connect into identical passage.For example, select controlled switch can be by trunk access 1 and trunk access by control passage
2 access passages 1, and trunk access 3 is accessed into passage 2.It thereby realizes different passages and exports different voltage and power, and
And number of battery cells therein and topological structure are also different.
