Problems solved by technology
The traditional temperature control method is to use PID to control the cooling fan. This method has the problems of large temperature fluctuations of the fuel cell stack and long adjustment time, which is not conducive to the normal performance of the fuel cell stack. During the PID adjustment process, short-term high temperature or even Can threaten the performance and life of the fuel cell system

The invention discloses a cooling fan control method of a fuel cell thermal management system, through precise control of the power of the fan in the fuel cell thermal management system, the thermal balance of the fuel cell system can be quickly realized, so that the fuel cell stack can work at the optimum set temperature In this interval, not only can the performance of the fuel cell system be optimized, but also the service life of the fuel cell stack can be extended.
Description
A kind of fuel cell thermal management system cooling fan control method technical field [0001] The present invention relates to a method for controlling a cooling fan of a fuel cell thermal management system. Background technique Temperature is a key parameter that affects the performance of fuel cell systems, and a reasonable thermal management system can ensure that fuel The stability of the temperature of the battery system under steady-state and dynamic load changes can improve the performance of the fuel cell system and prolong the life of the fuel cell. life. The traditional temperature control method is to use PID to control the cooling fan, this method has the temperature fluctuation of the fuel cell stack The problems of large size, long adjustment time, and unfavorable performance of the normal working performance of the fuel cell stack, may occur during the PID adjustment process. Short-term high temperatures can even threaten the performance and life of...
