The invention relates to a cooling system in a fuel cell electric vehicle and a method of controlling the cooling system in the fuel cell electric vehicle. The first chamber is configured to contain a relatively hot fluid. The second chamber is configured to contain a relatively cold fluid. A cooling power/fan power ratio of the positive displacement device at the heat exchanger is monitored, and thermal energy transfer between the coolant and the chamber is controlled based on the ratio. When the ratio is above a predetermined value or a range of predetermined values, then thermal energy from the first chamber is provided to the coolant in the coolant circuit and transferred into the heat exchanger, after which a portion of the thermal energy of the cooled coolant exiting the heat exchanger is provided to and stored in the second chamber. When the ratio is below a predetermined value or range of predetermined values, the stored cold thermal energy is released from the second chamber. The invention also relates to a method of controlling a cooling system.

    本发明涉及燃料电池电动车辆中的冷却系统和控制燃料电池电动车辆中的冷却系统的方法。第一室被配置成容纳相对热的流体。第二室被配置成容纳相对冷的流体。监测热交换器处的正排量装置的冷却功率/风扇功率的比率,并且基于所述比率来控制冷却剂和所述室之间的热能传递。当比率高于预定值或预定值范围时,则来自第一室的热能被提供给冷却剂回路中的冷却剂并被传送到热交换器中,在此之后,离开热交换器的冷却的冷却剂的热能的一部分被提供到第二室并存储在第二室中。当所述比率低于预定值或预定值范围时,存储的冷的热能从第二室释放。本发明还涉及控制冷却系统的方法。
