[0042] like figure 1 As shown, the present invention, a parallel battery cluster topology integrating circulating current suppression and state-of-charge equalization circuits, includes a plurality of voltage sources connected in series with the parallel battery clusters. The total number of the voltage sources is n, the first voltage source U 1 , the second voltage source U 2 , ..., the nth voltage source U n The positive terminals of the first battery cluster B are 1 , the second battery cluster B 2 , ..., nth battery cluster B n connected to the negative terminal of the first voltage source U 1 , the second voltage source U 2 , ..., the nth voltage source U n The negative terminals of the batteries are connected together to form the negative terminals of the parallel battery clusters, and the output current of the corresponding battery clusters can be controlled by controlling the polarity and voltage of the voltage source, thereby controlling the energy flow between...
