Vacanze elettriche 2022

Percorso un po’ tortuoso quest’anno, anche per il ritardo di 1 settimana nella partenza e vari appuntamenti con famiglia ed amici.

Le mie previsioni:
  • Percorrenza: 3.500km (viaggio A/R) + 1.500km (escursioni) = 5.000km totali
  • Durata viaggio A/R: direi che il minimo teorico sono 39 ore di guida + 8 ore per rifornimenti = 47 ore tutto compreso
  • Consumo: viaggio A/R = 550kWh, totale 800kWh
  • Spesa rifornimento totale: €312 (spesa presunta gasolio: € 475)

Ci vediamo al ritorno coi consuntivi.

Consuntivo e cosa ho imparato

Il viaggio si è svolto secondo il percorso previsto, con l’unica eccezione della tappa di risalita verso Assisi che abbiamo fatto sulla costa adriatica. Questi i dati principali:

  • Percorrenza: 3.772km (viaggio A/R) + 1.778km (escursioni) = 5.550km totali
  • Durata: non ho tenuto un diario così dettagliato, ma a spanne il viaggio A/R è durato circa 70 ore
  • Consumo: 873kWh totali
  • Spesa rifornimento totale: €285 (presunta a gasolio: €629); questo conferma la convenienza ANCHE per chi non può caricare a casa, attraverso un abbonamento flat.
  • La differenza tra consumi registrati dal computer di bordo e i consumi pagati alle stazioni (perdite di ricarica) è stata circa del 14%; è piuttosto alto, considerato che la maggior parte dei rifornimenti è stato effettuato nell’intervallo 20-80%, ma potrebbe essere dipeso anche dalle temperature molto elevate.
  • Il consumo (comprese le perdite di ricarica) è stato un buon 6,35 km/kWh, corrispondente a 406km di autonomia; nelle vacanze 2021 e 2020 i consumi erano stati un 15% più alti.
  • La Puglia è infrastrutturata con il programma Puglia Area Network: le stazioni SEMBRANO di Enel, ma non sono in circolarità, dunque non è possibile ricaricare con tessere di altri operatori.
  • Ho trovato parecchie stazioni dotate dell’ormai obsoleta presa 3A, inutilizzabile a meno di avere il carichino con la spina apposita.
  • A Policoro la stazione era geolocalizzata male e solo grazie ad un abitante della zona sono riuscito a trovarla; speriamo che la mia segnalazione al call center sia stata presa in carico.

Considerazioni finali

  1. Ho già avuto modo di mettere in guardia me stesso contro un’eccessiva disinvoltura nell’utilizzo fino all’ultimo elettrone: per due volte sono arrivato al rifornimento con meno del 3% (2kWh) di batteria, il che è davvero un rischio che dovrebbe essere corso solo quando si è assolutamente certi della disponibilità e del funzionamento della stazione di ricarica di destinazione.
  2. E’ facile dimenticarsi che non tutte le stazioni visibili su PCC sono attivabili con l’abbonamento flat di BeCharge; per l’anno prossimo la scelta ideale sono un mix di flat anziché una sola come ho fatto quest’anno.
  3. Nonostante abbia telefonato apposta per verificare al call center di BeCharge, la nuova flat parte SOLO dopo la scadenza temporale della prima: non se ne possono fare due nello stesso mese (anche se mi avevano detto di sì).
  4. Il roaming non si estende ai Call Center: in sostanza ciascuno da remoto può operare solo sulle proprie stazioni, il che riporta alla cautela di cui al punto #2.
  5. La peculiarità tutta pugliese di stazioni Enel installate da e-Distribuzione ma non in circolarità non merita alcun commento, ma solo di essere corretta; in mancanza, #2.
  6. Le formule di abbonamento sembra che siano state scritte dagli stessi intelligentoni che scrivono i contratti telefonici o energ… no, aspe’….!

Green hydrogen! The answer to all your energy needs!
Great! Let’s have it!
There you go!
Blimey, this is bloody expensive!
Well, this technology is early stage, we’ll need lots of research to improve electrolyzers and to scale up efficiencies
Gotcha, here is some public billions to do all that. How long is it going to take?
Can’t really say, these are super-scientific challenges nobody ever tackled, but in the meanwhile…
…in the meanwhile?
You can have Blue Hydrogen, almost as good as Green, made from Methane but with Carbon Capture
Sounds good, bring it on!
Here you go!
My goodness, this is almost as expensive as Green!
I know. Also this is leading edge technology which needs Research…
Here is some more public billions to fund Carbon Capture research
But costs will go down also because the captured CO2 is a valuable material
That’s great! You mean someone would pay to use the CO2 we capture? To do what?
Well, essentially to extract more oil. We pump it into an oil well that’s running out to squeeze more from it.
But that does not sound so attractive, what do we do with more oil?
We burn it, like we do with nearly all the oil we use
Let’s say we capture, 1ton of CO2, and how much oil we pull out?
About 4 barrels…
…which, once burned, produces how much CO2?
1.7 tons
But that’s MORE than the CO2 we started with! I don’t think this is such a great idea. Let’s go back to Blue Hydrogen which is almost as expensive as Green.
I know. In the meanwhile…
…in the meanwhile?
You can stick to Black Hydrogen from Methane steam reforming, cheap and plentiful…
…and emission-wise worse than the Methane it started from.
I know, but, hey, we can’t destroy the economy, can we?
And what about all these public billions I could have spent installing renewables?
Sorry, you know, research doesn’t always pan out.

A new problem to my car’s High-Voltage battery


July 11th (Sunday): this morning I wasn’t able to start the car whose dashboard showed the alarm you can see below. I therefore called Road Assistance because the Kona blocked my driveway and I could not exit with any other car; the car was taken to a deposit and delivered tomorrow to the authorized Hyundai service point (Autorino in Cava Manara, the closest to my house).

July 12th at 9AM I call to get information and to arrange a replacement car: the call center promises to have someone call me back a.s.a.p., but that never happens. I call again at 2PM and then at 4:15PM with identical results (i.e. nobody calls me back) so I have no idea what happened to my car. This behaviour mirrors exactly previous contacts I had with said service point. i.e. they never call you back.

As for the problem itself, it had happened identical in early April, while I was in Mantova on a work trip. The car was taken to the local Hyundai service point (Gruppo Ferrari) where it remained for nine days after which I got it back with the assurance that “the problem was fixed” an optimistic assessment which, as it turns out, was not justified.

PROBLEMS

  • My first problem is the unbelievable rudeness of the personnel at Autotorino which, despite my three calls only decided to call me this morning after I filed a formal complaint for poor service in writing.
  • The second problem are the many technical issues of this car. On top of the two I described, I had another three service stops due – I think – to a malfunctioning 12V battery, and I say “I think” because nobody was able to explain what the issue was or what they did to fix it. I think you will agree that for a two-years old car this is NOT acceptable.
  • The third problem is that this car is essential for my job: I travel a lot (one of the reasons I chose an electric car): a replacement car is a partial remedy, given it costs me a lot more to operate, and only if the issue happens when at home. In the episode of Mantova I had to waste a half-day to go get the car when it was fixed, but if that happens when I am in Napoli? Or next month (assuming I get it back by then) when on vacation in Sicily? Do you genuinely expect me to travel 3.000 kilometers to get it back?
  • The fourth problem is the fact that I am a long-time arthritis sufferer; my driving licence requires I drive only cars with automatic gearboxes; since it is impossible for me to speak with the service point, I cannot make them aware of this essential requirement.

CONCLUSIONS

I have read media reporting about a recall for the replacement of the HV battery for problems that seem similar to the ones I have, and I wonder if this behaviour isn’t simply a delaying tactic yo avoid performing such an expensive replacement under warranty. It would certainly help if Hyundai or its service points were a bit more forthcoming in explaining to its paying customers what’s wrong and how it’s going to be fixed.

It is fairly evident that the product you sold me was defective since the start and I am very close to defer the whole matter to a lawyer to obtain a replacement or a full refund, including damages and time lost.

UPDATES

July 14th: this morning I get a call from service workshop who asks two questions whose answer was in the letter I had sent (see above) and promises to have me recalled to figure out the issue of the replacement car. Obviously no one calls and therefore at 3PM I pay a physical visit to the workshop where they offer the most unlikely excuses for their rudeness in not calling me back and say that:

  • they are investigating, no diagnosis is yet possible.
  • the decision about the replacement car is up to Hyundai Motor Company Italy. I make clear that in a week I am due to depart for my already-paid-for holiday, that they have “investigated” for three days already, and that when the same exact problem happened in Mantova two months ago, the replacement car was issued in no time at all; I also remind them that my driving licence requires an auto gearbox car.
  • they have no clue about what happened in Mantova: apparently the information system doesn’t log the maintenance episodes by VIN number across the service network. I suggest not to perform again the same software updates performed in Mantova.

July 14th: in the evening service calls again stating that the Call Center “is about to call me” to sort out the replacement car issue, but I get no call.

July 15th: in the evening I get the call from the Call Center. I go through the list of my (simple) requirements: I live in Pavia, I can only drive cars with auto transmission; I then state upon request my drivetrain preferences: electric, plug-in hybrid, hybrid, petrol, diesel in that order.

July 16th: the ability to listen to its Customers is without question one of the best characteristics of Hyundai Motor Company Italy. Upon receiving the SMS announcing my car is ready I go to the rental company where I find…. a diesel car with manual transmission! Since I was going apeshit, and sensing he could be the innocent target of my wrath, the rental employee manages to find a car with auto transmission (but still diesel).

Carnival fritters

by Mirella Facchin

This recipe comes from the mom of my friend Alessandra. This is a traditional Carnival sweet (yes, we’re a wee bit early) well-known everywhere in Italy, albeit with different names depending on the region: “Chiacchiere” (=chit-chat) “Bugie” (=lies), “Cenci” (=rags), plus others which are meaningless also in Italian like “Frappe” “Crostoli” or “Galani”.

Health hypocrisy generated the monster of an oven version which in our family is tantamount to blasphemy, so I won’t spend any more time on it. Having said that, the eggs will make sure the dough absorbs very little oil, so after a minute or two of cooling, the fritters will be surprisingly dry.

Ingredients (serves 8-10)

  • 100g butter
  • 2 large tablespoons of sugar
  • 500g “00” flour (finely ground flour, if you don’t know what I am talking about, read this)
  • 2 whole eggs + 2 yolks
  • 2 tablespoons of whole milk
  • 4 tablespoons of rum
  • grated zest of 2 lemons

Melt the butter, add sugar and milk and a pinch of salt. Make a flour volcano and place this mix in its center, followed by the eggs, rum and lemon zest. Knead the dough thoroughly (at least 20 minutes, if available use a kneading machine) then let it rest 20 minutes before you roll it into layers “so thin you can see through”.

Rolling the dough is best done with a pasta machine like this one, working progressively through the rollers steps all the way to the last one (don’t cheat, though, only one step at a time !)

Cut the dough into sheets of 20×10 cm with two halfway cuts in the middle of each.

Heat peanut oil in a large frying pan to 170/180 °C and fry each sheet individually for no more than 30 seconds (see video), then put it to cool on kitchen paper.

Sprinkle generously with powdered sugar before serving, but eat carefully: they’re so thin they break easily!

Autentica?

Gira in rete questa foto, attribuita ad una persona che vive sulle mura della Città Alta di Bergamo: si vedono le luci della Città Bassa e, sullo sfondo, la skyline di Milano, visibile grazie all’aria resa limpida dall’assenza di traffico.

La Città Alta di Bergamo dista in linea d’aria da piazza Gae Aulenti a Milano circa 45,3km e la mia impressione è che da quella distanza Milano sembri un po’ troppo “grande”.

Ho allora cercato in rete qualche webcam puntata sulla stessa zona, ma il problema è che mutando la prospettiva la skyline diventa molto diversa; ne ho però trovata una collocata a Baggio (zona ovest di Milano), cioè in una direzione grosso modo opposta a quella da cui è presa questa foto, ma ad una distanza molto minore (solo 8 km); l’ho rovesciata per renderla sostanzialmente sovrapponibile a questa e ho aggiunto qualche didascalia:

Ebbene la separazione tra i grattacieli Allianz e Unicredit in questa immagine (presa da 8 km di distanza) è equivalente all’altezza apparente della Torre Isozaki (Allianz) stessa, mentre nell’immagine da Bergamo (presa a 45 km di distanza) è circa 5 volte l’altezza della torre.

Sono dunque portato a ritenere che l’immagine “da Bergamo” sia in realtà un falso.

Terza puntata

Questo post è la terza puntata (qui il riassunto delle puntate precedenti) delle mie disavventure con la batteria dei servizi della mia Kona EV 64kWh della quale sono peraltro molto soddisfatto.

In particolare, visto che sia Hyundai che l’officina non sembrano sapere che pesci prendere, ho deciso di cercare di capire cosa non ci sia da solo.

Ho dunque acquistato un data logger collegandolo in parallelo sui morsetti della batteria 12V; il vantaggio rispetto alla pinza amperometrica è che posso misurare e registrare la tensione della batteria senza aprire l’auto o il cofano e dunque in condizioni di perfetta quiete.

Ho precedentemente riferito di aver rilevato circa 4A in uscita dalla vettura spenta. Un successivo test mi ha permesso di verificare che dopo circa 25′ questa corrente scende a zero: la mia ipotesi dunque è che si tratti di sensori vari che vanno in quiete completa solo dopo questo intervallo di tempo.

Per farla breve, questi sono i risultati dei miei test. Tutte le ricariche sono state fatte arrivando al limite impostato sull’auto (100% per AC e 80% per DC) perché l’inconveniente si presenta solo quando la ricarica si interrompe e l’auto va (o meglio, dovrebbe) andare in stato di quiete.

Carica su wallbox domestica S&H Wally 7,4kW

Da grafico si vede chiaramente che la ricarica viene completata alle 2:27 e in quell’istante la tensione della batteria dei servizi scende bruscamente da 13,1V (valore che caratterizza tutta la fase di ricarica) a 12,5V per poi scendere costantemente nelle circa 6,5 ore successive fino a 11,9V (circa -1,8mV al minuto). A quel punto accendo l’auto e tutto torna normale.

Carica su caricatore centellinare Hyundai 12A

La carica termina alle 3:49 con la batteria dei servizi è a 13,1V; a fine ricarica il “gradino” è quasi inesistente (12,9V) e dopo 5 ore la tensione è ancora 12,8V; dunque la perdita di tensione è praticamente impercettibile: circa 0,3mV al minuto.

Carica su stazione Fast DC 45kW

La carica finisce alle 17:37; al termine la batteria dei servizi si porta a 12.9V e lì resta, senza “gradini” né erosione alcuna (addirittura guadagna qualche decina di mV) finché non rimetto in moto intorno alle 19:00.

Carica su stazione AC 7,4kW

Questo test è stato effettuato su una stazione Fast DC, collegando però l’auto alla presa Tipo2 in AC. Questa potrebbe erogare 43kW, ma l’OBC dell’auto ne accetta solo 7,4 ed in effetti questa è proprio la potenza a cui ricarico.

La carica finisce alle 18:05 con un brevissimo transitorio con la tensione che scende da 13,1V a 12,77 per poi riportarsi nei 10 minuti successivi a 13,1V dove resta fino al riavvio alle 19:13.

Conclusioni

Da questi test sembra evidente che l’inconveniente si presenta solo quando carico dalla wallbox di casa: l’erosione della tensione è però lenta e perché la batteria scenda sotto la tensione minima di accensione (che non so quale sia) sono necessarie almeno 8-10 ore di sosta dopo che è finita la ricarica.

In capo a S&H dunque capire cosa causi l’inconveniente.

In capo a Hyundai capire perché la funzione salvabatteria non intervenga a rimediare.

Why the Senate audition is NOT good news for Facebook

Screenshot 2018-04-11 11.24.15.png

By many accounts, mr. Zuckerberg’s Senate hearing yesterday was a roaring success: stock’s up and Senators appeared NOT to understand what Facebook does or how the Internet works. From a media standpoint

the Zuck 1 – U.S. Senate 0.

But that’s nothing new: lawmakers (not just American) rarely understand what’s happening at the bleeding edge of innovation. In truth, very few people do, and this explains why these very few people are obscenely rich and powerful.

This happened before: U.S. lawmakers did not understand the railways, did not understand mainframe computers, did not understand the Personal Computer – but seeing the immense fortunes amassed by people or companies like Cornelius Vanderbilt, IBM or Microsoft they clumsily tried to rein them in. In my time, both IBM and Microsoft ended up being hamstrung by their stormy relationship with the DoJ and while neither company was “made poor” (in fact they still rank among the world’s largest and most successful corporations) their world dominance streak was chopped.

The stock market witnessed Zuckerberg’s superiority in the hearing and bid the share price up, but IMHO they will soon realize that what they hailed as a victory is indeed a damning episode for Facebook: expect the emergence of a powerful legal compliance department which will dictate what can or cannot be done. Expect long and costly wranglings with the DoJ as U.S. (and European) lawmakers hammer down on its dominance, fueled by competitors’ lobbyists.

It was an old adage that “IBM was run by lawyers” and not many people may have noticed Microsoft’s current President is a Bradford L. Smith whom I have met and worked with when he was one of their senior lawyers.

Expect now EU Commission hearings (compounded by the well-known taxation ongoing issue, and maybe others.

Far from positive for the company, yesterday started a major, irreversible modification of the way Facebook does business.

Case studies from History (1)

I am looking forward to a very intense fall traveling schedule which will take me to Mumbai, Istanbul and Cairo in the space of a few weeks.

I will start with the last one, because I will be covering a whole new topic which I never discussed before in a public occasion, and that is

Propaganda vs. True Public Engagement

How is Propaganda different from True Public Engagement?

Is one leading to the other, or are the two opposed? And, has this changed with the advent of Digital, which removed all barriers to access making each individual a potential, if temporary, news channel?

More importantly, perhaps, did the transition to Digital usher an era of more authentic Communications, where people talk to people directly and information is free to travel across the world?

My impression is that after a very short period of under-evaluation, Propaganda has learned its digital ropes quite well, if nothing else because Propaganda has money and it can afford the best consultants.

One of the largest contracts I led was the Digital campaign for the 2009 European Elections: the Party that was our client won, even though with age I stopped claiming merit for that victory. Barack Obama is widely credited to have won especially the 2008 election thanks to masterful use of Social Media; across Europe, new euro-skeptic parties thrive on digital-only communications.

The Goebbels of our time have demonstrated they are as good at manipulating public opinion as they were in the ‘40s because Digital and Social Media are a channel like any other: they are not un-stoppable, they can be (and are) monitored. If anything, for this purpose they are better suited than most channels, because all that goes through them is already in machine-digestible form: as a matter of fact, some of the most advanced Artificial Intelligence applications are classified and used in military grade surveillance.

Moreover, both sides of any dispute have become so good at storytelling that very often it is quite difficult to figure out who are the Good Guys. I presume we can all think of contemporary geo-political scenarios that fit this description.

When I look at the world we all live in, alongside glorious examples of citizen journalism I see evidence of digital tools being very effectively used to recruit and indoctrinate distraught youngsters to become terrorist chrysalises, ready to blossom into the next Breivik or Abdeslam.

So I started looking at the past, where I found two stories that I believe are of relevance, as they show how in the past crises not dissimilar from the ones facing us right now have been addressed using two of the fundamentals of Communications: Messages and Reputation.

You can call these Case Studies from History.
