Degradation of materials is one of the most critical aging mechanisms affecting the performance of lithium batteries. Among the various approaches to investigate battery aging, phase-field modelling (PFM) has emerged as a widely used numerical method for simulating the evolution of the phase interface as a function of space and time during material phase transition process.
Learn MoreThe battery heating process is also included in the battery thermal management system. The best battery heating design must meet two goals: heating the battery in the shortest time possible and maintaining the temperature uniformity of the battery.
The strategy aims to strike a good balance between rapid heating of the battery at low temperatures and minimizing damage to the battery's lifespan without the need for an additional power source.
The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
Optimal control of ambient temperature may thus be achieved through a thorough examination of the synergy angle. Conversely, the initial temperature rise within the battery pack impedes the heat dissipation performance of the external flow field battery box.
The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance. The temperature uniformity is poor due to the narrow space, and the temperature of the water heating the battery is also decreased with the increase of the distance the water flows through .
The effects of different time durations are also examined. The results show that the proposed battery heating strategy can heat the tested battery from -20 °C to above 0 °C in less than 5 minutes without incurring negative impact on battery health and a small current duration is beneficial to reducing the heating time.
