Abstract: A controller comprises a DCM and a processor. The DCM sends a battery pack ID to a battery information server, and receives from the battery information server a charging/discharging parameter conforming to a battery pack corresponding to the battery pack ID. The processor uses the received charging/discharging parameter to control charging and discharging the battery pack.

Abstract: A battery information server (controller) includes a processor (first processor) that obtains position information of an electrically powered vehicle (vehicle) and battery information based on a battery pack ID (information) of a battery pack (battery) mounted on the electrically powered vehicle. The battery information server includes a communication unit and a processor (third processor) that determines whether or not the battery pack is in conformity with battery laws and regulations in a country (area) corresponding to the position information, based on information on the battery laws and regulations set in advance for each country and the battery information. When the battery pack is determined as not being in conformity with the battery laws and regulations, the communication unit transmits a result of determination by the processor to the electrically powered vehicle.

Abstract: An on-vehicle emergency notification device that performs notification processing when an emergency event of a vehicle occurs, using a power accumulated in a battery mounted on the vehicle, includes: a voice communication unit that performs voice communication with a notification center via a voice call when the emergency event occurs; and an image sending unit that wirelessly sends images around the vehicle to the notification center when the emergency event occurs. After the emergency event occurs, a wireless sending of images by the image sending unit is inhibited if a battery power level of the battery becomes lower than a predetermined value.

Abstract: An emergency notification device performs emergency notification to send an emergency notification to a notification center when an urgent event is generated on a vehicle, and test notification to diagnose whether the emergency notification can be performed, through a notification button that is a part of one user interface. This device has a normal mode in which emergency notification can be performed, and a test mode in which test notification can be performed, through an operation of the notification button, as well as a transit mode in which transition from the normal mode to the test mode can be performed with a predetermined vehicle operation in the normal mode as a trigger. The emergency notification device performs informing processing, which differs from mode to mode, through indicators and that are another part of the one user interface.
