The invention discloses a motor waste heat utilization method and device, a storage medium and a vehicle. The method comprises the steps that after the vehicle is powered on and started and an air conditioner heating function is started, a preset clock is triggered to start timing based on the outlet water temperature of a motor; the charge state and the battery temperature of the battery in a preset time period are obtained; determining the discharge capacity of the battery based on the charge state and the battery temperature; under the condition that the discharging capacity of the battery is sufficient, the air conditioner heat pump is controlled to absorb motor waste heat for heating; and under the condition that the discharging capacity of the battery is insufficient, the battery loop is controlled to absorb waste heat of the motor to heat the battery, so that the temperature of the battery is increased. According to the method, the discharge capacity of the battery is determined based on the charge state and the battery temperature of the battery, so that the motor waste heat utilization mode is reasonably selected according to the discharge capacity, the battery can keep sufficient discharge capacity in the low charge state and low-temperature environment, motor waste heat can be used for heating, and the economic benefit of battery energy consumption is improved.
