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
To keep batteries warm, especially in cold temperatures, several methods can be employed, ranging from passive to active solutions. Simple and effective passive solutions include insulation, battery blankets, and heated enclosures.
The ideal battery temperature for maximizing lifespan and usable capacity is between 15 °C to 35 °C. However, the temperature where the battery can provide most energy is around 45 °C. University research of a single cell shows the impact of temperature on available capacity of a battery in more detail.
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.
It goes without saying that battery pack thermal management is a critical functional aspect. The operating temperature of a battery plays a crucial role in its lifespan and performance, so it is wise to keep the temperature within the right range.
Simple and effective passive solutions include insulation, battery blankets, and heated enclosures. Insulating materials, such as foam or specially designed battery blankets, help to reduce heat loss and maintain a stable temperature by creating a barrier around the battery.
