Abstract

A battery cell balance circuit includes an AC/DC converter (300), a plurality of battery cells (Cell 1-Cell m, Cell 1-Cell 6), a plurality of switches (S<1A>-S<mB>, S<1>-S<m+1>, RL1-RL6), an isolated DC/DC converter (400), a circuit switch (S<C>), and a control unit (500). The AC/DC converter (300) receives an AC power (V<AC>). The battery cells (Cell 1-Cell m, Cell 1-Cell 6) are connected in series to form a battery link (L<CELL>). Each switch (S<1A>-S<mB>, S<1>-S<m+1>, RL1-RL6) is correspondingly connected to one battery cell (Cell 1-Cell m, Cell 1-Cell 6). The isolated DC/DC converter (400) is coupled to the switches (S<1A>-S<mB>, S<1>-S<m+1>, RL1-RL6) and coupled to the battery link (L<CELL>) in series. The circuit switch (Sc) is coupled between the AC/DC converter (300), the isolated DC/DC converter (400), and the plurality of switches (S<1A>-S<mB>, S<1>-S<m+1>, RL1-RL6). The control unit (500) provides a plurality of control signals (SRL1-SRL6, S1c-S7c, S<CC>) to correspondingly control the plurality of switches (S<1A>-S<mB>, S<1>-S<m+1>, RL1-RL6) and the circuit switch (Sc).
