The invention relates to the technical field of batteries, in particular to a new energy automobile discharging method, device and system. The method comprises the steps of responding to charging connection between a new energy automobile and target equipment, and obtaining initial resistance information of the target equipment in a preset time period; performing filtering processing on the initial resistance information based on a Kalman filtering algorithm to obtain a target resistance value; performing matching verification on the target equipment based on the target resistance value; if the matching verification is passed, acquiring first battery parameter information of the power battery and second battery parameter information of the target equipment, and judging whether the power battery can charge the target equipment or not based on the first battery parameter information and the second battery parameter information; if yes, generating a target discharge parameter based on a preset particle swarm optimization algorithm; and controlling the power battery to charge the target equipment based on the target discharge parameter. The method can reduce the energy loss in the discharge process.
