The present invention provides a start control system of a vehicle, including: an electronic control unit (ECU), a starter, an air conditioner, and a starting power supply. The starting power supply includes a starting battery and a battery management system (BMS). At a low-temperature environment, when receiving an ignition request signal sent by the ECU, the BMS detects the temperature of the starting battery. When the temperature is less than a preset threshold, the starting battery is connected to the air conditioner for a preset time, so that the starting battery effectively raises the temperature of the starting battery by means of discharging at a high current temporarily. The start control system of a vehicle improves an ignition capability of a vehicle in a low-temperature environment, extends a temperature range and an area of using the vehicle, and improves competitiveness of the vehicle. The present invention further provides a vehicle having the start control system of a vehicle.
