TEMPERATURE RAISING DEVICE

A temperature raising device includes a parallel circuit including a capacitor connected in parallel to a battery that is a temperature raising target, and an alternating current (AC) generation circuit connected to the parallel circuit. When capacitance of the capacitor is denoted by C, an inductance component of the battery is denoted by L, and a resistance component of the battery is denoted by R, C satisfies Inequality () and an angular frequency ω of the AC generation circuit satisfies Eq. (2).
