| Popis: | Excellent temperature characteristics of space Li-ion batteries can effectively improve the on-orbit operation to reduce the temperature fluctuation range and improve reliability. This paper adopts the hardware-in-the-loop approach, which organically combines simulation and experiment. This method not only effectively tests the thermal management system of the space batteries, but also simulates the characteristics of the system in real-time, and saves the high experimental cost. From the experiment, it is found that when the temperature of the inlet working fluid rises, the surface temperature rises significantly, and the maximum temperature difference is 4.9 °C. The steady-state settling time of the surface temperature also increases. When the flow rate of the inlet working fluid rises, the surface temperature decreases significantly, the maximum temperature difference is 3.9 °C, and the steady-state establishment time of the surface temperature extremely shortens. With the thermal load rise, the battery surface temperature increases obviously, the maximum temperature difference becomes 3.9°C, and the steady-state settling time of the surface temperature becomes longer. When the cycle remains the same and the charge/discharge times are dissimilar, the longer the discharge time, the faster the surface temperature rises, with a maximum increase of 34%. |
