The invention provides a fuel cell bus energy management control method. The method comprises the steps: enabling a vehicle control unit to determine first request fuel cell system output power according to the SOC of a power cell; determining the output power of a second request fuel cell system according to the SOC of the power cell and the vehicle speed; determining the output power of a thirdrequest fuel cell system according to the required power of the whole vehicle; taking the maximum value of the output power of the first request fuel cell system, the output power of the second request fuel cell system and the output power of the third request fuel cell system as the output power of the final request fuel cell system; and finally, enabling the vehicle control unit to send the final requested output power of the fuel cell system to a fuel cell system controller, and enabling the fuel cell system controller to control the fuel cell system to correspondingly execute the operation. The method is simple and feasible, the SOC change interval of the power battery can be reduced, the bus energy requirement is met, and the service life of the power battery is prolonged.
本发明提供了一种燃料电池公交车能量管理控制方法,整车控制器根据动力电池SOC的大小确定第一请求燃料电池系统输出功率;根据动力电池SOC和车速的大小确定第二请求燃料电池系统输出功率;根据整车需求功率的大小确定第三请求燃料电池系统输出功率,取第一请求燃料电池系统输出功率、第二请求燃料电池系统输出功率和第三请求燃料电池系统输出功率中的最大值作为最终请求燃料电池系统输出功率,最后整车控制器将最终请求燃料电池系统输出功率发送至燃料电池系统控制器,燃料电池系统控制器控制燃料电池系统相应执行。本发明简单可行,可降低动力电池SOC变化区间,满足公交车能量需求并延长动力电池使用寿命。
