Interesting article. Would really like to hear some feedback from some great minds. Mainsail? Lithium-Hybrid
Wouldn't a fuse on the lead acid battery blow before a thermal runaway occured?The article fails to delve into what happens when the lead acid battery fails internally, and they do. A large LFP bank has enough energy to cause a thermal runaway event in an LA battery that has lost a cell.
I was wondering the same thing. The AGM should have an MRBF fuse connected directly to it that is rated for just a bit more than the max charging current. wouldn't any current leading to a thermal runaway be greater than that and trip the fuse?Wouldn't a fuse on the lead acid battery blow before a thermal runaway occurred?
The load currents a likely to be much higher than max charging current... Think windlass or electric winch.rated for just a bit more than the max charging current.
If I am understanding the hybrid system correctly, the LFP battery is designed to take the vast majority of the load demands. The AGM will only come into play when the LFP has been dropped to below 13.0V and taken off line by the BMS. The LFP would have a seperate fuse rated for the max loading.The load currents a likely to be much higher than max charging current... Think windlass or electric winch.
