Specific embodiment
Below in conjunction with attached drawing, the technical solution of the utility model is further described, but the utility model and unlimited
In these embodiments.
The present embodiment proposes a kind of battery pack that can be switched in series and parallel, and the change for passing through the connecting terminal mode of connection of transmitting electricity is real
Existing battery pack is connected in series or in parallel, to realize different current or voltage output.
In conjunction with Fig. 1, which includes at least two battery packs 1, connector 2 and several are positive and negative with battery pack 1
The transmission of electricity terminal 3 that pole connects one to one, the connector 2 include several transmission of electricity connecting terminals 4, the transmission of electricity connecting terminal
4 one end is detachably connected with the transmission of electricity one-to-one correspondence of terminal 3, and the other end for connecting terminal 4 of transmitting electricity realizes battery pack 1 by wiring
Be connected in series or in parallel.
In the present embodiment, which further includes that the signal output end of several and battery pack 1 connects one to one

Son 5 is corresponded and is detachably connected, and the other end of signal terminal 6 is connect by wiring with electrical equipment.Signal terminal 5 wraps
The second collet 51 is included, one end of second collet 51 and signal terminal 6 is detachably connected.
Signal terminal 5 is separately connected the signal output end of battery pack 1, the signal that battery pack 1 exports by signal terminal 5,
Signal terminal 6 is connect with electrical equipment, and electrical equipment carries out the operation such as storing to the signal of 1 output end of battery pack.
This implementation is illustrated by taking two battery packs as an example in conjunction with Fig. 2-3.The battery pack include the first battery pack 11,
Second battery pack 12, the first battery pack 1 include anode A+, cathode A-, and the second battery pack 2 includes anode B+, cathode B-, and first is defeated
The transmission of electricity of electric terminal 31, second terminal 32, the third transmission of electricity transmission of electricity terminal 34 of terminal the 33, the 4th are connect with B-, A-, B+, A+ respectively, the
The one transmission of electricity transmission of electricity of connecting terminal 41, second connecting terminal 42, the third transmission of electricity transmission of electricity connecting terminal 44 of connecting terminal the 43, the 4th are distinguished
It is correspondingly connected with the first transmission of electricity transmission of electricity of terminal 31, second terminal 32, the third transmission of electricity transmission of electricity terminal 34 of terminal the 33, the 4th.When first
