And now Electrify America decides to join the Tesla charging plug club

Yesterday Chargepoint, operator of some 48,000 Level 2 charging plugs across the US, said that it plans to join the Tesla charging plug club (blog article).  Now, today, Electrify America (“EA”) has announced it will do the same.

One reason that the EA announcement is of interest is that EA operates mostly fast DC chargers (as distinguished from Chargepoint which operates mostly mere Level-2 chargers).  EA is the second-biggest provider of fast DC chargers in North America, after Tesla.

Two more domino clicks

We now have two more domino clicks with the by now seemingly inevitable shift in North America to Tesla-style charging plugs. As difficult as one might find it to believe, there is a company in the US that operates more charging stations than Tesla (48,000 charging ports compared with a mere 27,000 or so charging ports from Tesla).  And that company, which until now has used J-plugs for its charging stations, has just announced that it will migrate to Tesla-style plugs.  That the first of today’s domino clicks.

And the Society of Automotive Engineers (“SAE”), the standards-setting body for automobiles in North America, has announced that it will commence a standards-setting process for Tesla-style charging plugs. That’s a second domino click. Continue reading “Two more domino clicks”

The Osborne Effect and Tesla supercharging

Four car makers (Ford, General Motors (blog article), Rivian (blog article), and now Volvo (blog article)) have announced that starting about a year from now, their newly manufactured EVs will have a charging port that permits charging at Tesla supercharging stations.  This will doubtless trigger the Osborne Effect (Wikipedia article):

The Osborne effect is a social phenomenon of customers canceling or deferring orders for the current, soon-to-be-obsolete product as an unexpected drawback of a company’s announcing a future product prematurely.

The term alludes to the Osborne Computer Corporation, whose second product did not become available until more than a year after it was announced. The company’s subsequent bankruptcy was widely blamed on reduced sales after the announcement.

Rivian – the next domino click for the Tesla standard

A few weeks ago, Ford and Tesla announced Ford’s plans to start using Tesla-type charging ports on its newly manufactured vehicles (blog article).  Shortly thereafter, General Motors and Tesla made a similar announcement.  This prompted me to predict a series of domino clicks as other car makers announce similar plans.  And indeed we now have another domino click — Rivian.  Continue reading “Rivian – the next domino click for the Tesla standard”

Lots of Chargepoint Home Flex chargers have lost their green halo

Update on June 19, 2022:  As of a couple of days ago, my two Chargepoint Home Flex chargers have quietly started showing their green halo again, and the left-side LED for wifi is again a steady green light.  I believe this is due to the Chargepoint company somehow repairing its broken cloud.

There are something like a quarter million Chargepoint Home Flex chargers (photo above right) in service across the US.  When the charger is happy, the halo around the charging plug is green such as you see in this photo.  But in recent weeks, the halo has been white, for a substantial fraction of the Chargepoint Home Flex chargers that are in service across the US.  What does this change of the color of the halo mean?  Continue reading “Lots of Chargepoint Home Flex chargers have lost their green halo”

GM follows Ford in partnering with Tesla supercharger network

The world is filled with “network effects” (Wikipedia article).  Network effects are typically positive, resulting in a given user deriving more value from a product as more users join the same network.  If more and more users purchase VHS videocassette players, this prompts more film distributors to publish movies in VHS format.  This in turn prompts more users to purchase VHS videocassette players, and so on, leading perhaps to the demise of the Betamax format for videocassettes.  Today’s announcement that General Motors has agreed to partner with the Tesla supercharging network in the US comes on the heels of Ford’s announcement a couple of weeks ago that it had agreed to partner with the Tesla supercharging network in the US.  What factors probably contributed to these recent developments?  What does this mean for the future of the non-Tesla standards for EV chargers in the US?  Continue reading “GM follows Ford in partnering with Tesla supercharger network”

Where the smart drivers go to charge

(Updated to include fun fact about the color of the charging plug.) 

Let’s suppose you are driving along Interstate 70 and you decide to exit at Silverthorne, Colorado to do some Tesla supercharging.  There is a first supercharging station two minutes off the exit, having 12 kiosks, and there is a second supercharging station six minutes off the exit, with a mere 8 kiosks.  Which one should you go to for charging your car?  Continue reading “Where the smart drivers go to charge”
