EXHAUST GAS ENERGY RECOVERY DEVICE

An exhaust gas energy recovery device includes a power generation device driven by a turbine configured to rotate by an exhaust gas, a switching element connected to the power generation device, a first terminal connected to the power generation device via the switching element and for being connected to a first power storage device, and a second terminal connected to the power generation device and for being connected to a second power storage device, in which a terminal voltage of the first power storage device is lower than a terminal voltage of the second power storage device, and the switching element switches a destination to be charged by the power generation device to either the first power storage device or the second power storage device on the basis of magnitude of a direct current voltage output from the power generation device.
