DRIVE APPARATUS AND TRANSPORTER

摘要

A drive apparatus includes a first power storage, a second power storage, an electric motor, a voltage booster, an electric device. The second power storage is superior to the first power storage in energy to weight density and is inferior to the first power storage in output to weight density. The electric motor is to be driven with power supplied from at least one of the first power storage and the second power storage. The voltage booster is to boost a voltage output from the first power storage. The voltage booster includes a switch to electrically connect or disconnect the first power storage to at least one of the electric motor and the second power storage. The electric device is provided between the first power storage and the voltage booster. The voltage output from the second power storage is higher than a guaranteed operating voltage of the electric device.

主权项

1. A drive apparatus comprising:
a first power storage unit; a second power storage unit that is superior to the first power storage unit in energy to weight density, and inferior to the first power storage unit in output to weight density; a voltage step-up section that steps up an output voltage of the first power storage unit; an electric motor that is driven by power obtained from at least one out of the first power storage unit and the second power storage unit; and an electrical unit that is connected between the first power storage unit and the voltage step-up section, wherein the voltage step-up section includes a switching element that opens or closes a current path between the first power storage unit, and either the electric motor or the second power storage unit; and a voltage of the second power storage unit is higher than a guaranteed operating voltage of the electrical unit.
