Abstract

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.
