Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
Material selection and preparation Considering the operation temperature range of lead-acid batteries (−10 to 40 °C), 40 # semi refined paraffin wax is selected as the phase change matrix, with phase change temperature of 39.6 °C and latent heat of 238.4 J/g.
It is well known that all lead-acid batteries will have a shorter life when operated at a higher temperature. This is the case no matter what type lead-acid battery it is and no matter who manufacturers them. The effect can be described as the ARRHENIUS EQUATION.
Only at very high ambient air humidity (above 70%), water from outside the battery can be absorbed by the hygroscopic sulfuric acid. In summary, the internal temperature of any lead-acid battery (flooded and AGM) should not exceed 60 °C for extended time periods frequently to limit vaporization. 2.1. External and internal heating of the battery
Battery capacity is affected by ambient temperature. Capacity is maintained in warmer temperatures, but cycle life is reduced. Cooler ambient temperatures will reduce battery capacity, but cycle life is improved. Note: Cycle life loss of ~50% is expected for every 10˚C over 25˚C (77˚F)
Thermal management of lead-acid batteries includes heat dissipation at high-temperature conditions (similar to other batteries) and thermal insulation at low-temperature conditions due to significant performance deterioration.
