The charge control system includes at least a battery temperature control device, a cooling device, a heating device, and an integrated control device. The battery control device detects SOC of a battery. Based on the detected SOC, the integrated control device switches between a first charging mode in which the battery is charged at a substantially constant current and a second charging mode in which the battery is charged at a substantially constant voltage. In the second charging mode, the battery temperature control device performs rapid cooling control to control the cooling device such that it has a cooling capacity in the second charging mode higher than a cooling capacity in the first charging mode. Thus, the battery temperature is appropriately controlled to increase a cruising distance even when the electric vehicle is run immediately after completion of charging.
