The model has been parameterized to work with two different types of flooded lead-acid batteries and then further improved to allow simulation of PV and wind current profiles as well as pauses. The adaptation to different battery types is achieved by using the data sheet information on float lifetime and nominal capacity lifetime.
While lithium-ion batteries have gained significant market share due to their higher efficiency and energy density, lead-acid batteries continue to be a strong competitor in certain markets. Lead-acid batteries are more affordable, easier to maintain, and have a proven track record in the energy storage sector.
In another study, Svoboda et al. classified lead–acid batteries into categories for lifetime considerations of the components of renewable systems and for analysing the properties and performance of these systems.
AGM batteries, in particular, are becoming the go-to choice for start-stop systems in vehicles, as they offer higher power output and shorter recharge times. Lead-acid batteries have undergone significant improvements in their overall performance.
My issue is that the ECU shuts itself down randomly (power and comm leds are off). This can only be reset by physical turning of with the button on the unit. I tried a smart relay to turn the power off.
