A hybrid energy storage system for an elevator car includes a converter (684a, 684b, 684c) disposed on the elevator car (670) and receives power from a power source (661) and provides a first DC voltage to a first DC bus (675a) and a second DC voltage to a second DC bus, a first energy storage device (674) connected to the converter (684a, 684b, 684c) receives the first DC voltage on the first DC bus (675a), and a second energy storage device (672) connected to the converter (684a, 684b, 684c) receives the second DC voltage on the second DC bus. The system also includes a first load (690) connected to the first DC bus (675a) and a second DC bus (677a), and a second load (690) connected to the second DC bus (677a). Power is provided from the first energy storage device (674) to the first load (690) under a first selected condition and power is supplied from the second energy storage device (672) to the first load (690) under a second selected condition.
