·Your expertise is appreciated. While tangential, what are your current views on the evolution of EVs? Do you see any breakthrough battery technologies on the near horizon?
Lithium batteries give you the energy density needed to make EVs practical, but they come with tighter thermal limits and require a lot of support systems—cooling, monitoring, and cell balancing across thousands of cells. That’s necessary because once you scale up to large packs, it’s less about whether a cell fails and more about preventing that failure from propagating.
Those failure modes, especially when they can lead to destructive outcomes, aren’t always fully considered in practical discussions, but they do place real constraints on how these systems are designed and used. The required support systems add weight, introduce additional energy overhead, and increase overall system complexity, all of which can work against efficiency to some degree.
It’s also worth noting this isn’t unique to EVs. Modern vehicles in general have become more complex—ICE vehicles included. They have more electronics, more systems, more features, and more weight than ever before. That all adds cost both upfront and over time, and it can work against efficiency as well.
So some of these tradeoffs—complexity, cost, and efficiency—are really part of a broader trend in vehicle design, not just something specific to electric vehicles.
Where EVs work really well is in predictable use cases—shorter, defined routes where you can charge overnight at a lower, less stressful rate. That’s why they make a lot of sense for delivery fleets, municipal vehicles, and similar applications.
Where things get harder is with variability. Personally owned vehicles don’t always follow a predictable pattern, and long-distance travel still favors liquid fuels simply because of energy density and quick refueling.
That’s also why I think hybrid systems are a very practical middle ground right now. You can take advantage of electric drive where it helps, without needing extremely large battery packs or depending entirely on charging infrastructure.
From an adoption standpoint, I do think trying to mandate EV use in every situation can create frustration and tends to highlight where the technology isn’t the best fit yet. That can actually slow broader acceptance rather than help it. It usually works better when a technology is adopted where it clearly performs well and expands from there.
So overall, the technology is solid and improving, but like any large battery system, it comes down to use case. It works very well in some applications, and less well in others.
