  "textContent": "To improve power efficiency while suppressing complication of a component structure in execution of an equalization process between a plurality of cells connected in series, power supply system (1) is provided. In power supply system (1), control circuit (50) performs active balancing between a plurality of cells (E1 to E5, E6 o E 10, E11 to E 15) included in each of a plurality of series cell groups (M1 to M3), using a plurality of active cell balancing circuits (14, 24, 34), and performs passive balancing between the plurality of series cell groups (M1 to M3). Voltage detection circuit (13, 23, 33) connected to a series cell group being undergoing the passive balancing and consuming power is supplied with power from first power supply circuit (11, 21, 31). Voltage detection circuit (13, 23, 33) connected to series cell group (M1 to M3) being undergoing active cell balancing by active cell balancing circuit (14, 24, 34) is supplied with power from second power supply circuit (12, 22, 32) higher in efficiency than first power supply circuit (11, 21, 31).",
