Abstract

The invention discloses a hydrogen-electricity hybrid fuel cell bus energy management control method. The hydrogen-electricity hybrid fuel cell bus energy management control method comprises the following steps that vehicle pedal opening data and a SOC value of a power cell are collected; required power of a vehicle drive motor is calculated according to the collected data; a fuel cell power pointis determined according to the required power of the vehicle drive motor, a fuel cell polarization curve and the SOC value of the power cell; start and stop control over the fuel cell is determined according to the SOC value of the power cell; output power of the fuel cell is controlled according to the determined fuel cell power point; and on the basis of ensuring the vehicle drive required power, energy margin of the SOC of the power cell is maintained to the greatest extent, meanwhile, the fuel cell is enabled to work in an area with the optimal efficiency, and it is ensured in a balance interval of the SOC of the power cell, the service life of the fuel cell is prolonged on the basis of meeting the vehicle power performance.

Description

technical field [0001] The present disclosure relates to related technical fields, and specifically relates to an energy management control method and system for a hydrogen-electric hybrid fuel cell bus. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] A fuel cell is a device that directly converts chemical energy into electrical energy through electrode reflection. It has the advantages of diverse fuels, no pollution, low noise, safety, reliability, and easy maintenance, and the energy conversion rate is higher in actual use. Therefore, fuel cells are considered to be the best energy source to replace traditional engines. As a clean energy source, fuel cells have attracted widespread attention. Fuel cell vehicles emerged under such a background. [0004] Hydrogen-electric hybrid fuel cell bus, as a fuel cell powered vehicle, represent...
