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.

摘要： A power supply system includes a first energy storage, a second energy storage, a power transmission circuit, and circuitry. The circuitry acquires a request supply amount, a request output amount, and failure detection information. The circuitry controls the power transmission circuit in accordance with the at least one of the request supply amount and the request output amount such that a ratio of an amount of electric power supplied from or to the first energy storage and an amount of electric power supplied from or to the second energy storage is to be a first ratio in a normal operating. The circuitry controls the power transmission circuit in accordance with the at least one of the request supply amount and the request output amount such that the ratio is to be a second ratio which is different from the first ration in a partial failure state.

摘要： A drive system includes a first energy storage, a second energy storage, a voltage transformer, a drive apparatus, a detector, and circuitry. The first energy storage outputs a first voltage. The second energy storage outputs a second voltage different from the first voltage. The voltage transformer transforms at least one of the first voltage and the second voltage. The drive apparatus is driven with power supplied from at least one of the first energy storage and the second energy storage. The detector detects a fault in at least one of the first energy storage and the second energy storage. The circuitry is configured to control the voltage transformer in a first control mode or in a second control mode.

摘要： A drive system includes a first energy storage, a second energy storage, a driver, and a controller. The first energy storage is charged and discharged. A first amount of heat is generated by charging and discharging the first energy storage. The second energy storage is charged and discharged. The second amount of heat is generated by charging and discharging the second energy storage and is smaller than the first amount of heat. The driver generates driving power to move an electrically powered vehicle with electric power supplied from at least one of the first energy storage and the second energy storage. The controller controls temperature of the first energy storage and temperature of the second energy storage with a coolant flowing inside the electrically powered vehicle. The first energy storage is cooled by the coolant before the second energy storage is cooled by the coolant.

摘要： A motor is to be driven with power supplied from at least one of a first energy storage and a second energy storage. The booster is to boost a first voltage output from the first energy storage such that the first voltage and a second voltage output from the second energy storage satisfy a first condition, a second condition, and a third condition. In the first condition, the second voltage does not exceed a withstand voltage limit of the motor. In the second condition, the second voltage is lower than or equal to a maximum boosted value to which the booster boosts the first voltage with a maximum boosting ratio. In the third condition, the second voltage is higher than or equal to a minimum boosted value to which the booster boosts the first voltage with a minimum boosting ratio.
