Strategy for controlling rotating speed of high-pressure fan by fuel cell controller

The invention belongs to the technical field of electric vehicle refrigeration, and discloses a strategy for controlling the rotating speed of a high-pressure fan through a fuel cell controller, and the rotating speed of the high-pressure fan is calculated and controlled through the fuel cell controller according to the angle of whether a cab and/or a fuel cell have the refrigeration requirement or not. The rotating speed of the high-pressure fan can be accurately controlled according to the starting state or the non-starting state of the fuel cell, and therefore the requirement for cab refrigeration is met. And meanwhile, the starting frequency of the fuel cell can be effectively reduced. 本发明属于电车制冷技术领域，公开了一种燃料电池控制器控制高压风扇转速的策略，通过驾驶室和/或燃料电池是否有制冷需求的角度利用燃料电池控制器对高压风扇的转速进行计算和控制。本发明根据燃料电池处于启动或者未启动状态，都能精准的控制高压风扇转速，从而达到驾驶室制冷的需求。同时可以有效的减少燃料电池的启动频率。
