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.
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
Furthermore, ambient and internal temperatures affect the electrochemical reactions inside the battery cell. Therefore, LIBs have a normal operating temperature range without severe heat generation.
(Source) Though the optimal temperature for usage is around 20-25C (depending on what source you trust), which is probably why Vantage gives you a warning. Realistically you will never get a battery to be below ambient temperature, and having it sit just 4 degrees above ambient is quite good.
LIBs as a complicated electrochemical energy storage system will produce a lot of heat during the operating process, especially on high rate charge/discharge processes [17, 18]. In Zhang’s study, the temperature of a NMC battery will exceed 75 °C at a 3 °C discharging rate without any treatment (ambient temperature is 25 °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.
