Interesting that most of the batteries tested in this study were LiFePO4 chemistry, even though they were all categorized as Li-ion. I'm not a chemist, so I can't say if that's inaccurate or not.Toxic gases :I'll stick to LiFePO4 :-)
I agree that boating is an inherently risky activity, as is life. Risks should be understood as best we can, and choices made based on that understanding. I chose to build my small (1.2kW) pack using LiFePO4 to replace a lead acid battery that was destroyed in a capsize. I designed the new pack with the possibility of another capsize in mind.
A few thoughts came to mind after reading this study:
- there was a local incident where a PHEV accidentally rolled down the boat ramp into the ocean. It was only after being pulled from the ocean that the vehicle's battery overheated and caught fire. Maybe electric boats should be designed to allow their engine compartments to be flooded as a last resort to control battery fires? Food for thought.
- I'm aware of several boats have burned locally in the last few years. None of these were electric boats. This is not a new risk, just a new form of an old risk.
- yes, there are risks to electric propulsion, but I have really enjoy the benefits on my boat
