Lots of folks were forwarding a story about a battery lab at Penn State that has shown a battery that can be recharged in 10 minutes. This is good (and many other labs and companies have demonstrated other ways to do that. But my key reaction is that those who think it's a huge deal are still thinking of electric cars like gasoline cars that you fill up at filing stations. They aren't. With a recent EV, not on a road trip, you charge only at home while you sleep, which takes zero time. Fast charging is not of value there. An article about this can be found in
Environmental issues, energy and electric cars
Tesla's "battery guru" from Halifax, NS released a paper on some new battery cells they have been testing in his lab and getting 6,000 cycles from 0 to 100% on. That's a lot better than today's cells which offer 2000 cycles from 20% to 80% if you are lucky. This could be very big for electric cars, grid storage and it is suggested even robotaxis -- but their needs turn out to be more straightforward than originally thought. But it does bring down the cost.
A big question for most EV buyers is how much range they need. It depends on your commute, your driving area and how much you want to take long road trips, and where you want to take them, but most people will be pretty happy with the 200-250 mile range cars that are starting to come out. But do you want to pay extra for more than 300 miles of range and get that long range Tesla?
Here's an article where I outline how to make that decision:
Hyundai has put a solar panel on an electric car. Turns out that's "false green" and may end up using a lot of the solar energy to cool down the car after you park it in the sun. What do the economics on solar panels in cars look like?
Another Tesla car crash, allegedly on autopilot, teaches us something about how well (or not well) Tesla is doing with its claimed ability to use its fleet of cars to quickly learn to identify unusual obstacles and situations. Here, a Tesla on autopilot crashes into a tow truck sticking out into the right lane (injuring the Tesla driver.) The driver says it was on Autopilot but that he was distracted for a few seconds.
Tesla advertised that the Model 3 is the safest car ever based on NHTSA's tests. NHTSA wrote them a letter saying, "stop saying that, you can't compare these scores across different weight classes."
Here's some analysis of who is right and why Tesla wins in the end at NHTSA and Tesla spar over safety claims
RV parks already have the infrastructure for charging electric vehicles on road trips. They just need somewhere decent for the road trippers to sleep and they can exploit a whole new market. Some already rent little cabins. If they add glamping tents they can serve customers at a low cost and could quickly fill out the many gaps in the EV trip network. In my new Forbes site article, I outline the things they could do, and give some advice to drivers too.
I've written about how to make Tesla Supercharging work, you try to have a meal while doing that. Here's a proposal to make that work much better: Be able to order food from participating restaurants while on the way to the charger, and have it all timed perfectly to either:
Evidence mounts that sea level rise can't be avoided now, absent some miracle of geoengineering, and maybe not even with that. Even if you're one of those who insists human pollution isn't the cause, the planet is getting warmer, the ice sheets are melting at extreme rates.
When you buy an electric car, you can often choose among various battery sizes. The larger your battery, the more range you have -- and you may get some extra performance -- and the longer your pack lasts, but the extra capacity is very expensive and adds weight to the car. The truth is, most people only need the extra capacity of a long range car when doing road trips. A modest 150 to 200 mile range car is sufficient for driving around a town, depending on the town.
There have been ten different prices changes to Tesla Model 3s since I got mine just over 4 months ago. While one expects electric computerized vehicles to go down in price over time, most buyers didn't count on anything like this, and people who rushed out to buy "before the price goes up" are not happy.
This month we took an electric car road trip in the California desert to see the flowers. The idea of a road trip in the desert with an electric car would have been crazy not too long ago. Now it's becoming possible, soon it will be easy, but there's still lots to learn.
