Average energy consumption and instantaneous energy consumption display methods and devices of fuel cell automobile

Abstract

The invention relates to average energy consumption and instantaneous energy consumption display methods and devices of a fuel cell automobile. The average energy consumption display method comprisesthe following steps: calculating the current average energy consumption of the automobile under different working conditions, and displaying the average energy consumption and the unit corresponding to the average energy consumption, wherein the corresponding working conditions when the current average energy consumption of the automobile is calculated include a pure electric working condition that a fuel cell is not started and a hybrid power working condition that the fuel cell is started. According to the average energy consumption and instantaneous energy consumption display methods and devices of the fuel cell automobile, the accurate data of the energy consumption of the automobile are calculated and displayed according to the working conditions that the fuel cell does not start pureelectric power and the fuel cell starts hybrid power, so that a driver can know the energy consumption conditions of the automobile under different working conditions in real time, thereby helping the driver to optimize driving habits and realizing energy-saving driving.

Description

technical field [0001] The invention relates to a method and device for displaying average energy consumption and instantaneous energy consumption of a fuel cell vehicle, belonging to the technical field of fuel cell vehicles. Background technique [0002] The fuel cell system can convert hydrogen energy into electric energy, and at the same time achieve the environmental protection effect of zero emission or even negative emission. It is a new force in the field of new energy buses. The fuel cell bus adopts a hybrid power system, and its operating conditions are divided into pure electric power mode and electric-electric hybrid power mode in which the fuel cell engine is started. [0003] At present, some traditional vehicles, new energy pure electric vehicles and some hybrid vehicles can provide the driver with the average energy consumption and instantaneous energy consumption data under the current driving state and operating habits through the instrument, and the driver...
