  • Publication number: 20240133056
    Abstract: A control unit is configured to communicate with a terminal owned by a power company. When a hydrogen generation request is received from the terminal, the control unit determines whether hydrogen is to be generated based on a state of a hydrogen generation device, and transmits a determination result to the terminal. When a power sale request is received from the terminal, the control unit determines whether power is to be sold based on a state of the hydrogen generation device, and transmits a determination result to the terminal.

  • Patent number: 11130454
    Abstract: A module driver or a master obtains the load IDs of the respective first loads connected to the downstream side of the module driver, recognizes the classification of areas, such as door, roof and floor areas, or a module according to the obtained load IDs, and allocates an appropriate driver ID to the module driver in each area. Each first load has a load ID. The load IDs are allocated to the respective second loads on the downstream side of the module driver on the basis of the allocated driver ID. The area or the module is recognized on the basis of the combination of the load IDs of the plurality of first loads, whereby malfunctions caused by erroneous assembling of the first loads are suppressed.

  • Patent number: 11034314
    Abstract: In a vehicular power supply system according to an embodiment, passage current of a power MOSFET of an IPD of a sub power distribution box monitored by a sub controller of the sub power distribution box is transmitted from the sub controller to a main controller of a main power distribution box. When energy storage amount of a load-based path calculated by integrating the passage current received by the main controller exceeds a predetermined value which is a overcurrent state, the main controller determines that the load-based path is in the overcurrent, and notifies the fact from the main controller to the sub controller. The sub controller switches the power MOSFET of the IPD of the load-based path set to the overcurrent by the notification to a non-conduction state to interrupt the energization of the load-based path.

  • Patent number: 10879799
    Abstract: A power transmission system is provided. In the power transmission system, a plurality of power supply voltages are switched alternately and periodically, and is sent from an upstream module unit toward a downstream control unit as one system of output voltage. In the downstream control unit, a plurality of voltages from the inputted voltage is separated and supplied to loads, and the voltage is monitored so as to determine switching timing. Further, the downstream control unit is equipped with capacitors for each system of voltages, and thereby the voltages are maintained even during a time period when no power is supplied from the upstream module unit. A low voltage required by a CPU of the downstream control unit is generated by a voltage regulator of the downstream control unit. The power loss that is caused in generating power to be consumed by low-voltage loads can be reduced.
