The control end of individual logical gate is all connected with battery controller, battery controller control leading over the ground of each logical gate
Lead to or cut-off, thus control the duty of each lithium battery BTn.
In being embodied as of the present invention, described gate circuit Qn specifically uses the gate circuit being made up of two field effect transistor
Qn, field effect transistor gate pole is that the logical gate being connected with battery controller controls end, and the model that gate circuit Qn specifically uses is
8205；Described diode Dn is connected between negative pole and the ground of lithium battery BTn, and the model that described diode Dn specifically uses is
SS34。
As example of the present invention, for the application of most of M-BUS wired remote-transmission instrument, n takes
Value is 4, say, that constituted complete lithium battery group by lithium battery BT1 to lithium battery BT4, the control end of four-way switch gate circuit
Being connected with battery controller, battery controller controls lithium battery BT1 to lithium battery BT4 the most in turn by four-way switch gate circuit
Work, meanwhile, voltage detection module the output voltage of the n-th lithium battery BTn under detecting constantly the most in working order.
