Abstract
A drive device includes a first energy storage, a second energy storage, a voltage converter, a driver, and circuitry. The first energy storage has a first power weight density and a first energy weight density. The second energy storage has a second power weight density higher than the first power weight density and a second energy weight density lower than the first weight density. The voltage converter converts a voltage output from the second energy storage. The driver is driven with power supplied from at least one of the first energy storage and the second energy storage. The circuitry is configured to interrupt current from the driver or from the second energy storage to the first energy storage. The circuitry is configured to control the voltage converter.
