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.
The batteries have an operating range of -18°C to 55°C, but are recommended to discharge at 20±2°C. Under the optimal temperature conditions and with a 10Ω load, the battery is expected to reach its cutoff voltage defined at 0.9V in 480 minutes. Figure 2 shows the manufacturer's schematic diagram of discharge under these conditions.
Increased Internal Resistance: High temperatures can lead to an increase in the internal resistance of a battery. Internal resistance refers to the opposition to the flow of current within the battery. Increased resistance results in higher energy losses, reduced runtime, and decreased efficiency. 5.
The most significant increase of battery’s temperature is observed in the Lithium ion rechargeable battery. The effects of the temperature increase were strong enough that the adhesive holding the plastic wrapper to the battery begins to melt.
Self-Discharge: High temperatures can accelerate the self-discharge rate of batteries. Self-discharge occurs even when the battery is not in use, and is typically caused by internal chemical reactions. At high temperatures, these reactions occur at a faster rate, leading to a quicker depletion of the battery’s stored charge. 2.
Notably this influence depends on the battery type. For alkaline batteries, lower temperature results in the sooner occurrence of the sharp drop; for lithium primary batteries, on the other hand, lower temperature postpones the occurrence of sharp drop; for nickel-metal hydride batteries, the influence is not significant.
