@Bordeaux Sc, taking a picture I didn’t realize this beauty was arriving behind me, I know pedestrians sometimes get scared when the silent car passes by, this was the first time the other way around!
@Brive-la-Gaillard Sc, in onde minute another S will arrive. That/one in the picture is a 60D (a software limited 75), no fog lamps package
@Châteauroux Sc, in the middle of nowhere, it’s there, but it’s a scare

Stress? What stress?!

Driving with family can be fun. Driving with family in the Model S can be funnier. Or slower. Specially if your wife stresses on the charge % and every single stop is the time to wait for a battery topped…

Stress? What stress?! No stress when the goal is the magic number 9, followed by a zero and the symbol %: 90%.

90% and unstressed happiness happens


History being made today. It seems so far away, when all spoke on the bright future to say “These are the cars for the future today”, and suddenly the future faded away, EVs crushed in pain, it was yesterday, when Volvo had the C30 EV, three hundred of them, Michelin had its own brilliant EV R&D, and for what? For nothing from all of them, hurey!

But today, history is being made today: the first Tesla Model 3 is being assembled in the factory pipeline today. The revolution is on its way.

The 3, the future is here, very soon on the roads, by the 28th, the day

Charging rate

As more people move into “EV mode”, the same questions popup on a regular basis. Several recurrent ones are:

  1. I have a 220 V circuit with 30 A, how much do I get to charge my car? It depends on the kW charger of your car. You want a bigger kW charger for more range/h charge. It does not give you more when you feed the car 22 kW if your car only accepts 3.7 kW or 7.4 kW! Your car is the limitation! It’s very sad when, with a 7.4 kW charger available nearby, we see a 3.7 or 7.4 kW car occupying a 22 kW charger, it’s such a huge waist!! Specially if the person arriving has a 22 kW charger in the car and all 22 kW chargers are busy for slow charging cars and the only thing available is a slow 7.4 kW charger… Sad.
  2. How can I know my charging rate? For a consumption of ~200 Wh / 100 km, multiply your kWatt by 5 and you have approximately your charge rate in km/h. Divide by 1.6 to get miles. For 110 V 12 A: 110 × 12 / 1000 × 5 / 1.6 = 4 mi/h. For 220 V 30 A you get 220 × 30 ÷ 1000 × 5 ÷ 1.6 = 20.6 mi/h. 230 V 16 A 3 phase (11 kW) normally gets you 55 km/h. 32 A 3 phase (22 kW) gets you ~110 km/h.
  3. Why do I get less than the arithmetic tells? If the circuit delivers less V when loaded (typical), your W decreases and the charge rate will stabilize with less km or mi per h charging rate. A circuit delivers as much A as it can, depending on the Quality of Service and on the quality of the wire of the installation. Also, if the plug where you connect your EVSE is far away from the main distribution, you might get lower V when loading with higher A, the wire’s resistance plays an important role. Sometimes it pays to be attentive and to move to a plug near to the main energy distribution board. I’ve seen differences between 8 to 11 kW just for moving to a plug near the supply board, due to shorter wiring between the different plugs to the power supply board.
  4. As always, YMMV.

The share paradigm

The private car makes no sence since it stays unused for long periods of time, with it’s owner paying a lot for using a little. So, the idea is the share system, where you use on the go, you don’t own it, you pay per use. Maintenance (whatever maintenance is needed), small repairs, tires air pressure, these details will be taken care of by someone, not you the user. Oh, there’s already something similar called renting?!

From this number crunching perspective, private houses make no sence: most of the time you are at work, you don’t use your (!) house, you should only pay per use, the hours you sleep in. The same goes for any other piece of hardware you now own: your PC (Personal Computer), your smart phone, your whatever…

This reminds me a boss that demonstrated that no 24 bit per pixel (bpp) colour video boards would be needed: at that time the max resolution was 768×1024 pixels, and he rightfully said “you only need 768 k colours, there’s no need for 24 bpp!”. That’s the static number crunching reasoning at work. He would not grasp or understand that at some point the access to the 16 M 24 bpp colours had to be done, even if just for a transient brief moment, to edit those colours, and it was absolutely mandatory to have the on board 24 bpp to free choose what colours the final edit would be.

For the unused house during the day, you could devise a system where someone else would use your house while you are at work not using it. I can’t remember any business that could benefit from using parts of the house rented by the hour. Can you think of something?! No, thank you!

Call me old fashion, I want my car to seat still, wating for me, for me to edit whatever color I want any time of the day, evening or night in my car’s paint system!

24 bpp is mandatory, as is 24/7 access – but that’s me, YMMV

The present, the future, today

Yesterday I went to listen to a talk by Prof. Maria Helena Braga on high density new architecture batteries. Her work is remarkable – let me use some adjectives here: it’s mind blowingly good, Google her, you will be amazed -, and it’s highly promising in terms of (real world) fast charging super batteries: the time to market it’s not today, it will take time, but from yesterday talk one REALLY wishes that industry steps to bring the technology to real life applications could be shorter, faster! We need those batteries ASAP!

On the other side, I was amazed to listen to some Portuguese high authorities, speaking while introducing Braga’s talk, and later speaking again while introducing the Q&A period after Braga’s talk: a total of 6 Portuguese authorities spoke, I never saw so many people talking to present a guest’s talk… And listening to these authorities a strange thing happened to me: I was feeling I didn’t exist since what I do on a daily basis, from their words, was not possible! I heard “electric cars have no usable range”, “they take too much time to charge”, “the electric motors use rare earth materials”, “there’s no viable way to store electricity for off peak use” …

Power pack? Power wall? Model S? Model X? Model 3? And the other car manufacturers that, because of Tesla, started to present real solutions, not excuses, for new affordable electric cars? Where do these 6 people live? The Model 3 alone has now more than 600 thousand reservation holders waiting for their electric car. For an electric car with no range, that’s an awfl amount of people (600000!) mistakingly wanting an electric car!

I went to Braga’s talk driving a car that has +400 km of range on a charge, I can charge it with 400 V 300 A 120 kW and add +250 km to the range in less than 25 minutes, I drove +43000 km in a year and went to London, Brussels, Le Mans, and back, on electricity only, with as much hassle as driving any other car, actually with less expense, less frustration and much more enjoyment, no pollution, no noise. Three days ago a new record was set on a Tesla P100D: 901 km driven on a charge. The motors are purely three phase, no rare earth materials. I have friends (unfortunately not myself yet) that do have their houses with solar panels & batteries off the grid, it works, I’ve seen it, it’s not a dream and it’s economically viable.

Thank you so much to Prof Braga for that presentation. Thank you to the organizers that made possible this brilliant talk, a great step in the right direction.

But listening to the other words I was feeling from the future arriving to some past, not the present today.

Listening to Braga’s talk I felt our future is arriving today.

Time will tell

Spain has been high on Supercharger installs! It is common to see 5 points in the works, even in places very near to where Superchargers already exist. Wouldn’t it be nice to see some of those installs be placed further West? I clearly see an invisible barrier in the advancement of the Superchargers towards the West… Too bad we are in the far side of that … West.

West, the final frontier, where the land meets the sea…
And here we are, yet no Superchargers for us to see…

Congrats to the Spanish people, one more Supercharger location (with 10 charging stalls) already online and working, installed in a record time, and – surprise – so very near to another already existing Supercharging infrastructure!

cone: building site; red: installed; blue: permit asked; green: my personal markings for new Supercharger locations, based on digging the Web and Tesla published info over time; see how Granada, Manzanares and Tordesillas (near Valladolid) nailed previous green markings; and you have to love Girona and Barcelona, so few Supercharger stalls that one saddens for their bad luck.
