The Important Factors in Designing Low Temperature Resistant Battery Packs
One factor that is influential when designing a battery pack for operation at low temperatures is the duration of time the pack will need to operate for. As the table below demonstrates, the types of battery cells and heating technology we choose from differ between battery packs that need to operate for 4 hours or longer at a time versus battery packs that need to operate for short or intermittent periods of time.
| Low Temperature Environment Duration | Cell Options | Battery Pack Technology |
| More than 4 hours | Low temperature cell | Insulation and heat storage technology or heating pads |
| Intermittent or short periods of time | Low temperature cell or standard cell | Insulation and heat storage technology |
Other factors that influence the design, materials, and technology incorporated into each custom battery pack for low temperature include: the temperature range of the surrounding environment, space restrictions, performance requirements, and budgetary considerations.
Low Temperature Battery Pack FAQs
Can lithium batteries explode in cold temperatures?
If the battery’s operating temperature is lower than that of your lithium battery’s determined temperature range, yes, it can explode. This is because in extreme cold temperatures, the chemical reactions that take place in the battery become more active and lead to lithium precipitation, which damages the battery. When these battery packs are charged for a period of time in cold temperatures, it can cause fires or explosions. This is why it’s essential to opt for a special low temperature battery if you plan to operate your equipment in extreme cold temperatures.
How can CMB’s low temperature lithium batteries charge in cold weather?
CMB adopts heating film technology to boost the battery charger’s temperature to allow for safe and effective charging in cold environments.
Do cold temperatures reduce battery life?
Yes, when battery packs are operated in cold weather, it does reduce battery life. [Is this still true for CMB’s specially made low temperature batteries, or is the battery life protected because of the special features that low temp batteries offer?]
Do batteries do better in the cold or heat?
It is not good for lithium batteries to remain in cold or hot environments. At the ideal temperature of 25°C, the battery maintains a 100% performance rate. [Is this still true for CMB’s specially made low temperature batteries, or is the battery performance protected because of the special features that low temp batteries offer?]
How are CMB’s low temperature batteries kept warm in cold environments?
CMB’s specially designed low temperature lithium batteries use heating film technology to maintain an ideal battery temperature in cold environments.
