Regular Operating Temperature of Lithium-ion Batteries
2022-03-10
The environment in which a lithium-ion battery pack is used is also important to its life cycle. One very important factor is the ambient temperature. Too low or too high ambient temperature will affect the life cycle of lithium-ion batteries.
Conventional lithium-ion battery operating temperature: -20℃~60℃, but generally below 0℃, the performance of lithium-ion battery will be reduced, and the discharge capacity will be reduced accordingly. Therefore, the operating temperature of lithium-ion batteries to play the full performance is usually 0~40℃ (the temperature of lithium-ion batteries required by some special environments is different).
The charge/discharge cycle of lithium-ion batteries at high temperatures is unstable. Prolonged high temperature or connection to the power supply tends to cause the battery to expand. At the same time, the resistance of charge transfer of the battery increases and the dynamic performance of ion transfer decreases. And the charging performance is also significantly reduced by increasing the constant voltage charging time at low temperature. Equipment using Li-ion batteries may be subject to conditions such as vibration, shock and collision during transportation or normal operation. Some lithium-ion batteries are charged and discharged while communicating with the system and receiving data information at a certain frequency.
There are many factors that affect the life cycle of a lithium-ion battery pack. Lithium-ion batteries are being used more and more extensively and the demand for lithium-ion batteries has become more demanding in terms of quantity and quality. Life cycle directly affects the service life and quality of lithium-ion batteries, so it is necessary for manufacturers to study the factors that affect it.
