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
By reducing the gap between the battery and the plastic support, this not only saves the space in the battery pack, but also improves the uniformity of heat dissipation and reduces the temperature rise of the battery pack. The test results show that the maximum temperature difference of the pack is 3 °C, and the maximum temperature is 36.7 °C.
It can be seen from Fig. 2 a that the maximum temperature of the battery pack is 40.1 °C, the minimum temperature is 30.5 °C, and the maximum temperature difference is 9.6 °C.
At very low temperatures, that battery degrades faster than it should. Hence, it is crucial to maintain the homogeneity of the temperature distribution within a battery pack. While the trend of fast charging is catching up, batteries touch considerably high temperatures during the charging process.
Performance at Low Temperatures In cold temperatures, like below 15°C (59°F), lithium batteries experience reduced performance. Chemical reactions within the battery slow down, causing decreased power output. Shorter battery life and diminished capacity result from these conditions.
High temperatures (above 60°C or 140°F) can speed up battery aging and pose safety risks. Extreme temperatures shorten battery lifespan and reduce efficiency. Controlled environments and thermal management systems help maintain safe battery temperatures.
