Abstract

The present invention provides a driving device, a conveying device, an electrical installation device, and a control method optimal for cooling a system including a plurality of electric storage devices with different heat generation values. The drive device includes: a first accumulator; a second accumulator that generates less heat by charging and discharging than the first accumulator; One side is driven by the electric power obtained to output the power of the electric vehicle; and the control unit controls the temperature of the first storage battery and the second storage battery through the cooling medium flowing inside the electric vehicle. The first electric storage device and the second electric storage device are arranged inside the electric vehicle so as to be cooled by the cooling medium in order of the first electric storage device and the second electric storage device.

Description

technical field [0001] The present invention relates to a drive device, conveying equipment, and control method including a plurality of electric storage devices with different characteristics. Background technique [0002] Patent Document 1 describes a vehicle equipped with a fuel cell power supply system. The vehicle includes: a fuel cell; an electric storage unit composed of a capacitor connected to the fuel cell and a rechargeable battery; an electric motor serving as a power source of the vehicle connected to an output portion of the fuel cell and the electric storage unit; and an electric motor provided between the output portion and the electric storage unit. The PDU (Power Drive Unit) between the electric motors, in which the constituent items of the power system including the fuel cell, the power storage unit, and the PDU, is arranged so that the upper limit temperature and the heat generation value can be reduced to Cool in large order. The upper limit temperatur...
