The present disclosure provides a method and system for determining a pure electric available power and a vehicle, the method being applied to a vehicle including a fuel cell, the vehicle further including a battery pack and a motor, the fuel cell and the battery pack being electrically connected to the motor, wherein the method includes: monitoring a current travelling state of the vehicle and a current on-off state of the fuel cell; acquiring a maximum peak power outputted by the motor, a maximum output power of the battery pack and a starting-up power of the fuel cell; and according to the current travelling state, the current on-off state of the fuel cell, the maximum peak power, the maximum output power and the starting-up power, determining the pure electric available power.

Pure electric available power determination method and system, and vehicle

The present disclosure relates to the field of vehicle technology and provides an energy recovery control method, a system, and a vehicle. The method is applied in a vehicle, and the vehicle comprises a drive motor and a battery electrically connected to the drive motor; a first energy recovery torque curve with respect to the drive motor is pre-configured in the vehicle, and the first energy recovery torque curve is used to indicate a correspondence relationship between vehicle speed and energy recovery torque of the drive motor. The present disclosure performs reduction on a first energy recovery torque curve by means of utilizing a reduction ratio, allowing energy recovery in accordance with a relatively low torque strength when a usable charge power of the battery is unable to satisfy a preset power requirement corresponding to the first energy recovery torque curve.
