The output voltage of n-th lithium battery BTn under in working order, is connected one between the negative pole of each lithium battery BTn and ground connection
The individual logical gate being collectively formed with gate circuit Qn by diode Dn, the control end of each logical gate is all controlled with battery
Device connects, and is controlled the on or off over the ground of each logical gate by battery controller, thus controlling each lithium battery BTn's
Working condition.
And, described gate circuit Qn specifically using the gate circuit Qn being made up of two FETs, make by FET gate pole
It is the logical gate control end being connected with battery controller, described diode Dn is connected to negative pole and the ground of lithium battery BTn
Between.
And, the concrete model 8205 adopting of described gate circuit Qn, the concrete model adopting of described diode Dn

Road, the control end of each logical gate is all connected with battery controller, controls each logical gate by battery controller
On or off over the ground, thus control the working condition of each lithium battery BTn.
In of the present utility model being embodied as, described gate circuit Qn is specifically using the door electricity being made up of two FETs
Road Qn, FET gate pole is the logical gate control end being connected with battery controller, the concrete model adopting of gate circuit Qn
For 8205；Described diode Dn is connected between negative pole and the ground of lithium battery BTn, the concrete model adopting of described diode Dn
SS34.
As an instantiation of the present utility model, for the application of most of M-BUS wired remote-transmission instrument, n
Value be 4 that is to say, that complete lithium battery group, the control of four-way switch gate circuit are constituted by lithium battery BT1 to lithium battery BT4
End processed is connected with battery controller, and battery controller controls lithium battery BT1 to lithium battery BT4 successively by four-way switch gate circuit
Take turns to operate, meanwhile, by voltage detection module constantly detect just in working order under n-th lithium battery BTn output voltage.
