A restart determination device 4 includes a voltage value acquisition unit 44 that acquires a first voltage value between terminals of an energy storage device during an idling stop for stopping idling of an engine, a current value acquisition unit 45 that acquires a value of a current flowing through the energy storage device during the idling stop, a calculation unit 49 that calculates an internal resistance value of the energy storage device during the idling stop, based on the first voltage value, the current value, and a no-load voltage value, and a determination unit 51 that determines whether or not a restart of the engine is possible based on the internal resistance value and an operating voltage value of a starter motor of the engine.
