An apparatus for equalising the charging of series connected battery cells (E1..n),
a plurality of controlling modules (MOD1..n) connected to the electrodes of the cells, each of the modules having an inverter (PL1..n) connected to the cell terminals (P1..n,N1..n); a rectifier (BR1..n); a controlling terminal (A1..n) which connects the AC side of the inverter with the rectifier;
and a switch element (SW1..n) to connect or disconnect between at least one of the cell terminals (P1..n) and an output terminal of the rectifier (BR1..n),
a capacitor (C1..n-1) is connected between the controlling terminals (A1..n) of the adjacent controlling modules (MOD1..n), the inverter (PL1..n) in any one of the controlling modules is operated to discharge the cell modules (E1..n) connected thereto,
meanwhile the switch elements (SW1..n) in other controlling modules are closed so that DC voltages output from the rectifier circuits are applied to the cell modules connected thereto. |
