Temperature effect on batteries

Last Updated: Feb 27, 2018 11:45AM MST

How do I account for the impact of cold temperatures on batteries for stand-alone solar systems?

 

Effect of internal temperature on your battery can be modeled using the Advanced Storage Module (ASM) in HOMER Pro. Two types of temperature curves determine how it impacts your battery's performance.

1) Temperature (C) vs Capacity (% of nominal)
2) Temperature (C) vs Lifetime (years)

Here is an article from our online help manual that provides more information about modeling the thermal characteristics of the battery in the ASM module.
