1. A method for determining a pure electric available power, the method being applied to a vehicle comprising a fuel cell, the vehicle further comprising a battery pack and a motor, the fuel cell and the battery pack being electrically connected to the motor, wherein the method comprises:
by one or more processors, monitoring a current travelling state of the vehicle and a current on-off state of the fuel cell;
by one or more processors, 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, wherein the starting-up power refers to a minimum output power of the fuel cell when driving the motor by using the fuel cell has a higher efficiency than an efficiency of driving the motor by using the battery pack, and the current travelling state comprises a current gear state of the vehicle and a current on-off state of an energy-recovery function; and
by one or more processors, 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 and displaying the pure electric available power in a dashboard;
the step of, 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 comprises:
when the current gear state of the vehicle is a non-travelling gear state, and/or the energy-recovery function is in an on-state, and/or the fuel cell is in an on-state, determining the pure electric available power to be 0; and
when the current gear state of the vehicle is a travelling gear state, the energy-recovery function is in an off-state, and the fuel cell is in an off-state, according to a smallest value among the maximum peak power, the maximum output power and the starting-up power, determining the pure electric available power.
