Claim:
1. A storage battery apparatus, comprising: a chassis including an inhaling port and a discharging port; a battery module that is a structural body constructed by electrically connecting a plurality of batteries, the battery module being arranged in the chassis; a fluid device programmed to introduce a cooling medium for cooling the plurality of batteries into the chassis and to discharge the cooling medium, after having cooled the plurality of batteries, from the chassis; a plurality of temperature detectors including a first temperature detector programmed to detect the temperature of the cooling medium introduced into the chassis, a second temperature detector programmed to detect the temperature of the cooling medium discharged from the chassis, and a third temperature detector programmed to detect the temperature of at least one of the batteries and the battery module; and a control unit programmed to receive electric signals output from the plurality of temperature detectors, the control unit including: a temperature detection unit programmed to detect, on the basis of the electric signals output from the plurality of temperature detectors, the temperature of the cooling medium introduced into the chassis, the temperature of the cooling medium discharged from the chassis, and the temperature of at least one of the batteries and the battery module, and a fluid-device-operation control unit programmed to control the operation of the fluid device on the basis of the temperatures detected with the temperature detection unit, wherein the inhaling port and discharging port are separately disposed on both sides of the battery module, wherein the plurality of temperature detectors are disposed at least at the inhaling port and discharging port of the chassis, wherein the control unit is programmed to diagnose if the plurality of temperature detectors and the fluid device are abnormal or not on the basis of a comparison between the temperatures detected with the temperature detection unit and the plurality of temperatures including the temperature of the cooling medium introduced into the chassis, the temperature of the cooling medium discharged from the chassis, and the temperature of at least one of the batteries and the battery module, and wherein when the fluid device is in operation, the control unit is programmed to diagnose that:
