Electric car update. (See also post 3.)
Summary as may be too long for some: I have been north of Vallenar and south of Concepcion with EV recently; all fine, chargers work fine.
I have now used the Copec fast chargers 35 times in total. It was fine 33 times and there were 2 times the charger didn´t work: with no solution/fix from the staff when this happened. The real solution is to always stop with enough range to get to the plan B charger. That´s why I have been stopping about every 100km even though the battery is often 50%-60% full when I stop to charge.
My car´s range averages 240km (even on the motorway) but varies with conditions. This assumes 100km/h on the motorway however, not higher speeds.
A good thing about an EV is you can charge anywhere there is an electric socket. I have also charged successfully at 4-5 different people´s houses by passing a cable through a window.
Slow charging is at 1.5kW with my car so it can take 20 hours to charge from 0% to 100% (!) so slow charges are not for a full charge unless overnight. At a 50KW Copec fast charger it takes minutes to charge.
I have done two long road trips from the RM recently. One in August to Saltos de Itata and Laja and Concepcion; and another one in September to Vallenar and the flowering desert.
Going north, the last fast charger is at La Serena, so I charged in a hotel in Vallenar (Puerto de Vega) that had a courtyard private parking and they reserved me a space next to the socket. From there it was possible to do a 200km circuit seeing the flowering desert and return to the hotel.
The longest gap between charging points on the network is 145km between Los Vilos and Socos. On the way up I left Los Vilos with 93% and got to Socos with 29%, driving at 90km/h average to save energy. On the way back I left Socos with 93% and arrived at Los Vilos with only 13% which was a surprise - implies 183km total range, compared to the usual 240km. I think the winds in that section were an issue (those of you who have driven it might recollect it is full of wind turbines), but the variations of range under various conditions are something to keep an eye on.
From La Serena to Vallenar is 200km so I just drove at 80km/h rather than 100km/h with the air con off to be absolutely sure of making it. It used 87% of the battery on the way there (uphill) and 76% on the way back (downhill). On the way there I pulled off at La Higuera and plugged it at a store on the town plaza for a few hours just to make sure.
Hills just aren´t a big problem because you use double or more on the uphill but no net energy on downhills due to the regen braking. At one stage I went 32km downhill and at the end the amount of energy in the battery was the same! Driving north there are monster hills but I am still getting 250km effective range at 100km/h with air con/heating off or low.
North of Los Vilos is adventurous but Los Vilos to Temuco is not. Going south is more relaxing as the chargers are closer together. I got all the way to beyond Chillan without ever going below 48% battery level. And that was only with the Copec network. There are two other networks on that route - Shell and Enel X that I haven´t even tried yet.

Amazingly, in all the 35 times I´ve been to fast chargers (the majority this year), I´ve never had to wait for another car to finish (although I do deliberately avoid the very busiest days). Only two times was there anyone else there and both times they were just leaving, both were vans/small trucks. One time a taxi pulled up just as I was leaving. I´ve never seen a private car at any of them. It´s usually completely quiet. Electric car sales have not even reached the 1% level yet, very slow growth.
Both the 1198km return trip to the south and the 1745km return trip to the south cost me 39,000 pesos in electricity. The reason the shorter trip was the same cost as the longer trip was because on the shorter trip I generously offered a hotel 10,000 for an overnight charge (far more than the value of the actual electricity) whereas on the longer trip the hotel in Vallenar didn´t charge me for 3 days of charging. Most of the cost was at Copec, which is charging 250 pesos/kWh. When charging from home at normal electricity cost you can travel over 1000km for more like 20,000 pesos!
The journey from the south RM to La Serena took 8.5 hours including all the time stopped at chargers. The same journey is possible in a petrol car in 6.5 hours including one stop for a meal and to fill up the tank.
