A recent study detailed ways in which EV charging could cost more than gasoline. But in reality it generally costs much less
A trip on "The Loneliest Road in America" followed by the backroads of southern Utah s State Route 12 tests the limits of road tripping in an EV far from fast chargers
Not long after several automakers agreed to switch to using Tesla s NACS charging plug and to have their customers charge at the Tesla Supercharger network, 7 major au...
Right after Ford switched to NACS, GM has joined the party. With the top 3 US EV makers on NACS and CCS left with the foreign makers (and Stellantis which just started doing EVs) CCS is dead. Except for $7B in government subsidies. They ruined the CCS charging network, but maybe if they think about it, we can find a way to get this money to doing things the superior way Tesla did it without subsidies.
Ford Motor company has announced that starting next year, Fords will get access to Tesla's supercharger network via an adapter, and later, new Fords will be made with the Tesla NACS built in.
New rules greatly increase the time until solar panels pay for their cost, making it more important to store the power in batteries or cars, and even sell to neighbors.
Austin, TX, April 1 2023 - Tesla announced today that it's new low-cost car, known as the Model 2, will not come standard with a steering wheel or pedals. That's not because it will only work with Tesla's "Full Self Driving" system, but rather because they have been made virtual, through AI and the interior camera used for driver monitoring.
Tesla’s “Investor Day” caused much disappointment — even tanking Tesla stock — because there was no big announcement as expected, notably of their new low-cost, next generation vehicle. However, they actually let out a number of important details abut the vehicle, most of what you need to know — other than when you will be able to buy it. I calculate the list price of the new car will be around $26,000 -- under $14,000 with rebates in some states.

Tesla has done their investor day. No big announcements but tons of detail. About 20 minutes after it ends (it's still going at 4:50pm) Mario Herger and I will do a live post-show stream looking at highlights of the program.
Tesla has tested some new Superchargers that will allow non-Teslas to use them. These stalls have the built in CCS adapter known as the "Magic Dock" but otherwise have the same short charging cord common to Tesla Superchargers — a cord that can’t readily reach the charging ports on many non-Tesla cars. We may see some fights.

Rental car companies are starting to rent EVs, which is great for many rentals. But Hertz and Avis/Budget have a fat fee if you don't return it recharged, and on some rentals that can be a real burden as you can't just "stop by the gas station for 5 minutes on the way to the airport." Though if your hotel has charging, it's even easier to refill than a gas car.
So I examine what all the rental companies do and what the fee means and how they charge the cars in this Forbes.com article.
An annoying paper argues that self-driving cars will use huge amounts of compute and thus have a giant carbon footprint. The boring way that it's wrong is that the compute load will not grow as they suggest.
The more interesting way that it's wrong is that self-driving EVs will draw most of their power from no-emission generation sources like solar and nuclear, even if they do use a lot of power.
Here's a digest of some of my recent postings on Forbes.com
A filing suggests Tesla may be putting a radar back in their cars, but this time a high resolution radar, which is a bit like the LIDAR they swore was a crutch. It would be a good idea.
Generally it doesn't make sense (and isn't that green) to have off-grid solar compared to grid-tied solar. However, a new company sells a self-contained solar EV charging station for parking lots which they claim is cheaper than on-grid, because you can just get it delivered in one day with no permits, planning, wiring or construction.
It's true that all those factors are now the biggest element of charging and solar installations.
Thanksgiving is back baby. In 2019 a storm caused lines at some EV chargers. Will it repeat this year, and how do you handle the peak demand for long distance road travel?
Read some pre-holiday thoughts at How will EVs handle the Thanksgiving crunch?
Two stories today:
France will require all parking lots with over 80 spaces to put in solar panels. That's huge, and means the power will be generated right where cars are charging in the morning -- no grid distribution needed.
France Mandates Solar Panels On Most Parking Lots; A Great Marriage With The EV
In a short interview snippet, Karpathy, who recently stepped down from being director of AI for Tesla, explains their reasoning for taking out radar, ultrasonics, and never using LIDAR or detailed maps.
"The best part is no part" is Elon's philosophy, and it's a valid one, if you are an automaker who wants to lower costs. But is it the right philosophy if you want to be first on the road with a safe robocar?
A press release from Electrify America, the largest non-Tesla charging network, revealed that their average stall is used slightly more than once a day.
I explore what that might be and what it means, with questions about how much people road trip in non-Teslas and the issues with poor reliability of these stations. And I point out ways to improve that reliability, including failing operational at the risk of giving out some free electricity.
Tesla is conducting a vote among owners on where to put new Superchargers. This will identify popular locations, but popularity may not be the only metric to use to decide where fast charging goes. Tesla paved the way by creating chargers not to use in your home town, but so that you would feel confident you could take your EV on long road trips -- something not possible before. The best choices may be small and rural, where people only go rarely, but where they want to feel they could go if they wanted.
