Abstract: A controller for a hybrid vehicle performs charging control when a shift range of the hybrid vehicle is a first range, and does not perform the charging control when the shift range of the hybrid vehicle is a second range, the charging control being control of charging a power storage device with electric power generated by a generator driven by an engine. The controller records diagnosis information when an SOC of the power storage device is equal to or lower than a first threshold value and the shift range of the hybrid vehicle is the first range, and does not record the diagnosis information when the SOC of the power storage device is equal to or lower than the first threshold value and the shift range of the hybrid vehicle is the second range.

Abstract: A vehicle capable of running by using dynamic power of a motor includes: a battery to perform input/output of electric power for the motor; a fuse to be connected in series with the battery and to melt when an electric current exceeding a permissible value flows; and a control apparatus to restrict magnitude of the input/output electric power of the battery to less than an upper limit electric power. The control apparatus calculates a degradation level of the fuse such that degradation proceeds whenever temperature of the fuse exceeds a threshold temperature, and reduces the upper limit electric power when the degradation level of the fuse exceeds a target degradation level. The target degradation level is a value that is lower than a limit degradation level corresponding to a degradation level when the degradation of the fuse reaches a limit and that becomes higher as mileage of the vehicle increases.

Abstract: The present teaching provides a power supply system capable of appropriately performing replacement or repairing of a component of a module where a problem occurs without stopping the entire operation, in a case where the problem occurs in of the module in a plurality of modules. The power supply system includes a plurality of sweep modules, a problem detector, an indicator, and a controller. Each sweep module includes a battery module and an electric power circuit module. The problem detector detects a problem for each sweep module. The indicator indicates a sweep module in which a problem is detected. In a case where a problem is detected in the sweep module (S4: YES), the controller causes the indicator to indicate a failure sweep module in which the problem is detected (S5). The controller disconnects the failure sweep module from a main line, and continues sweep control (SG through S8).

Abstract: A power supply system includes a main line, a plurality of sweep modules, and a control unit. Each sweep module includes a battery module and a power circuit module. The power circuit module switches between connection and disconnection between the battery module and the main line. The control unit executes sweep control for sequentially switching the battery modules which are to be connected to the main line. The control unit maintains connection of a refreshing module which is to be subjected to refreshing charging/discharging to the main line while sweep control is being executed in a state in which the refreshing module is excluded in at least one of outputting of electric power to the outside and inputting of electric power from the outside.
