The invention provides an energy conversion device, a cooperative control method and device, a storage medium and a vehicle. The cooperative control method comprises the steps of obtaining first heating power according to target charging and discharging power, and obtaining target quadrature-axis current and target direct-axis current according to the relation between the first heating power and the target heating power; calculating a first duty ratio of each phase of bridge arm in a PWM rectifier according to the target quadrature-axis current, the target direct-axis current, the target charging and discharging current, the sampling current value on each phase of coil and the position of a motor rotor, and calculating the duty ratio of a bridge arm connected with an inductor in a reversible PWM rectifier according to the target charging and discharging current and the inductance current sampling value; and obtaining the duty ratio of each phase of bridge arm, and controlling the PWM rectifier according to the duty ratio, so that the current output by an external battery or power supply equipment flows through a motor coil to generate heat, and meanwhile, two or three of a chargingand discharging process, a heating process and a torque output process cooperatively work.
