A control apparatus for a vehicle determines whether to perform either a first control or a second control. In the first control, power is transferred between a power supply facility outside a vehicle and a power storage apparatus during stopping of the vehicle. In the second control, power is transferred between a rotating electric machine and the power storage apparatus through an inverter during traveling of the vehicle. In the first control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a first limit value. In the second control, the apparatus performs control of the inverter to set the controlled variable to be equal to or less than a second limit value. The apparatus sets either the first or second limit values to a value suppressing a decrease in a maximum dischargeable power of the power storage apparatus.

Control apparatus for vehicle

A battery management device is configured to set a limited measurement range that limits a range for measuring a voltage of each of a plurality of batteries for a vehicle. The battery management device is configured to measure the voltage of each of the plurality of batteries within the limited measurement range.

Battery management device and battery device

A battery management system includes a monitoring device and a controller. The monitoring device is arranged in a housing accommodating a battery. The monitoring device monitors the battery and acquires battery monitoring information that includes information indicating a state of the battery. The controller performs wireless communication with the monitoring device and executes a predetermined process based on the battery monitoring information. The monitoring device holds imperfect information that is battery monitoring information indicating failure of data transmission/reception between the monitoring device and the controller. The monitoring device retransmits information corresponding to the imperfect information from next time the battery monitoring information is transmitted.

System and method for battery management

A battery management system includes a monitoring device and a controller. The monitoring device is arranged in a housing accommodating a battery, monitors the battery and acquires battery monitoring information that includes information indicating a state of the battery. The controller performs wireless communication with the monitoring device and execute a predetermined process based on the battery monitoring information. The controller transmits a request for battery monitoring information to the monitoring device. The monitoring device transmits the battery monitoring information to the controller in response to the request. The controller determines whether missing of the battery monitoring information has occurred based on a correlation between the battery monitoring information acquired from the monitoring device via wireless communication and relationship information held by the controller related to the battery monitoring information.
