Abstract

 
Battery pack is the main energy storage element, and directly affects the performance of electric vehicle. This paper selects the forced air cooling of horizontal battery pack as the study object, and researches the heat dissipation performance of different operating conditions with FLEUNT software. Results indicate that: according to the four kinds of transient state conditions and steady state condition, the temperature rising of horizontal battery pack is significantly higher than the temperature difference; when the electric vehicle beginning to decrease speed, the curve of temperature rising and temperature difference rise, it shows that the internal heat continuously rising up, so even the electric vehicle beginning to decrease speed, the fan must work. Then the reference basis for heat flow field characteristic analysis of horizontal battery pack is offered.
