Tesla network outage reveals challenges of connected vehicles

Recently Tesla had a network outage which caused a very small number of customers to be unable to authenticate payment at superchargers -- and thus be stranded unable to charge. Due to the larger outage, they could not put in a new credit card either. (The system lost their working cards, they did not have bad cards.)

While it seems only a few were affected, it shows the challenge of having anything critical depend on a network that might go down.

How the grid will handle all cars being electric

When California announced it will ban the sale of new gasoline cars in 2035, a lot of people wondered how the electric grid would handle all that new electrical demand.

The answer is (almost) "easy-peasy" thanks to solar being cheap if you have storage tech, and cars all have storage.

I outline why in a new Forbes.com article at The grid will handle it

Uber and Lyft will go all electric, but a lot has to change first

Uber, following Lyft, announced a big push towards electric rides, declaring all rides will be electric by 2030. That's a good goal, but as I outlined earlier, there are reasons your Uber is not usually electric today. They need to find ways for lower-income drivers to own electric cars and a place to charge them overnight, and also briefly during the day, and we have to wait for the cars to get cheap. I outline the issues in this new article on Forbes.com

A guide to camping road trips with a Tesla or other EV

With few other travel options available, everybody's taking road trips, and trying to avoid Covid in hotels, camping where they can. Here's a new article from the Forbes site on charging your car while staying at RV parks and other locations so you can tent it and get off the main roads on your trip.

Slower chargers (2KW and 50KW) might be better for EVs than 7KW and 250KW

In EV charging, there's a big contest to see who can be the fastest, with 250KW and 350KW chargers competing with Tesla's superchargers. But charge-really-fast is "gasoline" thinking and it's much more expensive. For the same money, for example, a corporate parking lot would be better served with 40 Level 1 (2KW) chargers and 4 Level 2 (7KW) than 15 Level 2. And a new generation of cheaper 50KW chargers in places we stop for an hour could make more sense than 250kw ones.

Top 17 surprises from a year of driving a Tesla EV

Before I bought an electric car, I knew it would be different and I was ready for it. Even so, here is my list of 17 things that I didn't quite expect, that I only realized after driving one for a while.

California regulations are no cause for panic but they show "gasoline thinking"

If you read stories that California just put in new regulations that will change all the per-minute chargers and Tesla superchargers, don't worry, the changes are not that big and don't apply to chargers for some time. But it is worth examining how the regulations, such as they are, exhibit 20th century "gasoline thinking" by imagining that the same rules that apply to gas pumps should apply to electric charging stations. See about it in my Forbes site article:

EV fast charging connector battles and standards wars might be OK

It's a common lament that because there are so many EV charging plugs (including the 4 fast-charging systems -- Tesla, Chademo, US-CCS and Euro-CCS) that we need a universal standard, so that we can get the goal everybody wants of being able to charge any car anywhere.

How to save a lot of money when installing electric vehicle charging in your home

Often when you attempt to install an EV charging station in an older home, you find that the old 100 amp service on your panel is not enough, and the electrician may quote a very large price to replace the panel and upgrade the service.

There are ways to avoid paying thousands of dollars by putting in a modestly smaller circuit, and you may find it charges you just fine. Here is a guide to how to get away with less than a 50 amp plug and save many thousands.

Battery, ICE, Hybrid: What About Temporary Mixes?

I was thinking about all the different variants of battery powered and hybrid cars, and thinking about the BMW i3 REX, which is a medium range PHEV that uses a small, cheap motorcycle engine to drive a generator. I think there might be two new types of semi-hybrid cars with this approach, so I wrote up a summary of all the types, and where the new modes fit it, particularly a plan to make cars with a receiver in which a temporary generator module can be placed.

Can An Electric Car World Handle Thanksgiving Travel?

If the world switches to mostly electric cars, how will they handle the charging on peak travel days like Thanksgiving? I wrote an article on some thoughts for that, and on evacuations as well.

EV Electric cost goes up 25%, nobody blinks, plus why your Uber isn't electric

Here are two recent articles on the economics of electric vehicles.

On Nov 1, PG&E, probably the most common power company for electric vehicle owners, raised the cost of their EV off-peak rate by about 25% in exchange for making the off-peak period last longer. Nobody even noticed, even though a 25% rise in gas prices would be a major calamity in the eyes of many. I look into that math and why nobody cared in:

Cities stuck in last mile, Stupid Cities, Scooters and the future of Hydrogen

Two articles this week from 3 conferences I attended.

First look at How Cities are Stuck in the "last mile" and other observations from a conferences on cities and new mobility. I examine how scooter companies are working with cities, and how self-driving car tech is mapping cities by keeping the infrastructure dumb.

Recharging in 10 minutes is less exciting than you think

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

Tesla battery guru and new super-lifetime cell

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.

How to pick which range of Tesla or other EV to buy

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:

A solar panel on an electric car is probably false green

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?
