The application discloses a sliding energy recovery method. The method comprises the steps that in the running process of an electric vehicle, whether the electric vehicle meets the triggering condition of sliding energy recovery or not is judged; whether the power battery is allowed to be charged or not is determined when the electric vehicle meets the triggering condition of sliding energy recovery; when the power battery is allowed to be charged, a contactor is controlled to be connected with the power battery so as to convert sliding kinetic energy of the electric vehicle into electric energy to be stored in the power battery; and when the power battery is not allowed to be charged, the contactor is controlled to be disconnected with the power battery, one of a front motor and a rear motor is controlled to enter an energy recovery mode to recover energy, and the other one of the front motor and the rear motor is subjected to flux weakening treatment to consume energy recovered by the front motor or the rear motor. The application further discloses a sliding energy recovery system, an electric vehicle and a computer readable storage medium, and when the electric vehicle triggersthe sliding energy recovery condition, the electric vehicle can recover sliding energy to charge a battery or supply power to a power consumption device.
Description
technical field [0001] The present application relates to the technical field of coasting energy recovery, and more specifically, to a coasting energy recovery method, a coasting energy recovery system, an electric vehicle, and a computer-readable storage medium. Background technique [0002] Due to its own hardware structure, energy consumption and cruising range requirements, electric vehicles are usually designed with the function of coasting energy recovery. When the coasting energy recovery function is activated, the electric vehicle converts the kinetic energy of the vehicle sliding into electrical energy through the motor and stores it in the power battery, so as to effectively reduce energy consumption and increase the cruising range of the vehicle. However, when the state of charge of the current power battery is higher than a certain threshold, continuing to convert the kinetic energy of the vehicle sliding into electrical energy and store it in the power battery m...
