摘要： A system and method for controlling a low-voltage DC-DC converter (LDC) voltage of a hybrid vehicle are provided. The LDC voltage is optimally adjusted based on which driving mode the vehicle enters, thereby improving fuel efficiency. The method includes determining whether the hybrid vehicle is driven in a regenerative braking mode and whether a value of a state of charge (SOC) of an auxiliary battery is equal to or greater than a first critical value set as a value when charging of the auxiliary battery is unnecessary during the driving in the regenerative braking mode. When the value of the SOC of the auxiliary battery is equal to or greater than the predetermined first critical value, the driving mode is switched from the regenerative braking mode to an electric vehicle (EV) mode, and to variably adjust an LDC target voltage in the EV mode.

摘要： A power distribution method and system for a fuel cell vehicle is provided. The method includes deducing an amount of moisture in a stack of a fuel cell, when a supply amount of air of the stack of the fuel cell is decreased and determining a state of the fuel cell based on the amount of moisture. Additionally, the method includes deducing allowance power of a regenerative braking of a driving motor using maximum power of the regenerative braking of an air compressor and chargeable power of a high voltage battery based on the determined state. The regenerative braking of the driving motor is then adjusted to prevent actual power of the regenerative braking of the driving motor from exceeding the allowance power of the regenerative braking.

摘要： A power supply system includes a fuel cell, a power storage device, a first voltage adjusting device, a second voltage adjusting device, and a controller. The controller is to control the first voltage adjusting device and the second voltage adjusting device. The controller is to switch the second voltage adjusting device from a direct coupling state to a voltage adjusting state in a case where a first absolute value of a first difference between a secondary voltage of the second voltage adjusting device applied across a load and a fuel cell voltage is less than a predetermined allowable voltage value or in a case where a second absolute value of a second difference between a fuel cell current being to flow from the fuel cell into the first voltage adjusting device and a target current value of the fuel cell current exceeds a predetermined allowable current value.

摘要： A vehicle includes an electric power storage, an electric power generator, a rotating electric machine, and circuitry. The rotating electric machine is driven with electric power stored in the electric power storage and/or generated by the electric power generator to move the vehicle. The circuitry is configured to calculate target driving force for rotating electric machine, to detect surplus electric power which is generated due to a response delay of the electric power generator upon decreasing an amount of electric power generated by the electric power generator when the target driving force decreases, and to drive the rotating electric machine, when detecting the surplus electric power, with a phase current different from a maximum efficiency phase current with which an electric current value or electric power loss of the rotating electric machine is smallest so that the rotating electric machine consumes the surplus electric power.
