A blood reservoir being capable of reducing damage to blood stored therein. In the apparatus, information recorded in an information storage medium is read. A detection cutout is formed in the packaging body, for receiving insertion of a sheet remainder counter. The contact holes of the drain are provided with plugs of refractory material to avoid spiking between the metal and silicon. The at least one controller may request that a battery charger of another vehicle draw a specified current, and may establish a battery charging schedule with the another vehicle for the battery charger if, after issuing the request, the at least one controller detects a drop in voltage on the power distribution circuit. Reliability of the device is thereby improved.
