The temperature uniformity of the battery pack is improved obviously by using the flexible graphite. Meanwhile, the cascade cooling method can reduce the drastic temperature fluctuation and improve the temperature uniformity of the battery pack under non-equilibrium states.
A sub-optimally designed battery pack reaches higher temperature fast and does not maintain temperature homogeneity. According to the best design practices in the EV industry, the temperature range should be kept below 6 degrees for a vehicle to perform efficiently. Fig 1. Cell Temperature for Case I
However, the thermal performance of lithium-ion batteries is a major concern, as overheating can lead to safety hazards. This study aims to investigate the impact of structural parameters on the temperature field of battery packs, with a focus on, the width of wedge-shaped channels, inclination angles, and gaps between battery cells.
The results show that the battery pack has a good cooling and lightweight effect, and the maximum temperature difference of the battery cells could be kept below 5 °C. The temperature uniformity of the battery pack is improved obviously by using the flexible graphite.
The investigation focuses on the thermal characteristics in the process of the BTM, such as the equilibrium temperature, temperature variation rate, and temperature difference, etc. The results show that the battery pack has a good cooling and lightweight effect, and the maximum temperature difference of the battery cells could be kept below 5 °C.
External factors such as location, seasons and time of the year decide the ambient temperature conditions. Batteries do not perform well when it is too hot or too cold. Poor thermal management will affect the charging and discharging power, service life, cell balancing, capacity, and fast charging capability of the battery pack.
