A hybrid energy storage system for an elevator car includes a converter disposed on the elevator car and receives power from a power source and provides a first DC voltage to a first DC bus and a second DC voltage to a second DC bus, a first energy storage device connected to the converter receives the first DC voltage on the first DC bus, and a second energy storage device connected to the converter receives the second DC voltage on the second DC bus. The system also includes a first load connected to the first DC bus and a second DC bus, and a second load connected to the second DC bus. Power is provided from the first energy storage device to the first load under a first selected condition and power is supplied from the second energy storage device to the first load under second selected condition.
