摘要： A rotor of a rotating electric machine includes a rotating shaft. A coolant flow path is formed in the rotating shaft. The coolant flow path includes a first flow path and a second flow path. The first flow path extends from one end part of the rotating shaft toward another end part along an axial direction of the rotating shaft. The second flow path extends toward the other end part of the rotating shaft on an outer circumferential side of the first flow path. The coolant flow path further includes a communication flow path. The first flow path and the second flow path communicate with each other via the communication flow path.

摘要： Provided is a charge control system capable of reducing costs for reuse of a battery module. The charge control system includes a charger, a plurality of IPUs, and a CAN bus, and each IPU includes a battery, a contactor, and a battery ECU. Based on operation information provided via the CAN bus, the battery ECU causes the contactor of one IPU from among the plurality of IPUs to provide power supply to the battery belonging to the one IPU and causes the contactor of a rest of the IPUs to disconnect power supply to the battery belonging to the rest of the IPUs, thereby performing control such that the charger charges the battery belonging to the one IPU without concurrently charging the battery belonging to the rest of the IPUs.

摘要： When the supply of DC power from a first power generation device to a first power supply circuit is cut off, a control device disconnects the first power generation device from the first power supply circuit and a connection circuit using a contactor device, thereafter connects the first power supply circuit and a second power supply circuit to each other, causes electric power to be supplied from a second power generation device to between the first power generation device and the contactor device via a precharge circuit, and determines whether or not a short circuit has occurred between the first power generation device and the contactor device.

摘要： The objective is to suppress the spread of noise without installing a dedicated noise suppression component around the connection parts of busbars. A busbar connection structure includes a connection part and a cover. The connection parts electrically connect a first busbar, which is connected to the circuit of the first device, and a second busbar, which is connected to the circuit of the second device. The cover is for preventing contamination, covering the area including the connection parts. The cover includes a conductive part as a region of a conductor, at least over a range including directly above the connection parts.

摘要： A solid state battery includes an electrode laminate including a first solid electrolyte layer, a positive electrode, and a second solid electrolyte layer sequentially laminated on a negative electrode. The positive electrode includes a positive electrode tab extending therefrom. One of the first solid electrolyte layer or the second solid electrolyte layer includes a porous substrate. One other of the first solid electrolyte layer or the second solid electrolyte layer does not include a porous substrate. When the electrode laminate is viewed from above, outer peripheral ends of the first solid electrolyte layer and the second solid electrolyte layer are located outside an outer peripheral end of the positive electrode, and the first solid electrolyte layer and the second solid electrolyte layer are bonded to each other in a region not opposed to the positive electrode and the positive electrode tab.
