Electric Car Etiquette

[RobertArthur]

@ Antonia, a clever question. Many studies around and hands-on experience. Batteries don't like (extreme) cold. They prefer moderate temperatures, around 20 degrees C. Too cold, too hot, they don't like it. Totally discharged lead-acid car batteries - only water inside - will freeze. This will not happen to li-ion batteries, but their performance goes down at low temperatures and will need a special charging technology. Interesting: the case of Norway, how to keep all those EVs moving in wintertime?

Renault considers introducing battery-swapping in its electric cars

But will you be happy to swap your brand-new battery for a clapped-out one someone else has abused?

I did make suggestions above to cover that possibility.

But presumably the car manufacturer will own the battery and would just be renting it to you? They'd guarantee a certain level of charge at each swap.

I've been renting a propane gas bottle for cooking for over 25 years and getting compatible refills. I wonder how long manufacturers would guarantee to provide a replacement battery?

My thinking was people would still want to charge at home, not being restricted to swapping at their local garage.

AC charging at home requires a lot of patience, even if there is a raccordement triphasé capable of delivering the necessary power, your puissance souscrite: an example, the Hyundai Kona.

According to ENEDIS: Dans 80 % des cas, la recharge se fait à domicile.

A crosscountry in the EU, and in Gallia interior, needs some careful route planning. A study by the EU: More charging stations but uneven deployment makes travel across the EU complicated.

Battery swapping: Renault is considering it, NIO (PRC) is building it already. Reading this morning's newspapers I discovered that I've been thinking about the feasability of this concept without checking the facts of avant-garde EV technologies.

A translation of one of these articles, about the NIO ET7: " The car tested has the 100 kWh battery pack. With that, you can theoretically get a driving range of 580 kilometres. During this test, it was over 400 kilometres. But what sets Nio apart from other manufacturers is its battery swap system. You can swap an empty battery pack for a new one filled with power within six minutes. To do so, however, you have to go to a special swap station."

NIO ET7 news: a bird's-eye view.

That doesn't fit in with the best ideas!

@ Nomoss, there are other problems as well, one of the German newspapers (Bild) just mentions the following:

" Politicians are betting on the energy revolution: e-cars and heat pumps are being promoted with subsidies. Sales are booming.
But now Klaus Müller (51), head of the Federal Network Agency, is warning: the green technologies could lead to power outages!
Müller told the "Frankfurter Allgemeine Sonntagszeitung": "If so many new heat pumps and charging stations continue to be installed, then local power outages in the distribution grid are to be feared if we don't act."

Economics Minister Robert Habeck (53, Greens) has tasked Müller with the power grid problem, the report says."

[niemeyjt]

Yes, closing power stations and then rolling out more and more electricity dependant projects was never a good idea.

Will anyone learn from Germany? Of course not.

[RobertArthur]

@ Niemeyjt, grid problems everywhere, new connections not possible anymore in several cities and regions, also in The Netherlands. Once upon a time - sixties, seventies - the infrastructure looked futureproof, these days are gone. You simply cannot transport more power over an already maxed out grid. It took more than a century to build this infrastructure, doubling or tripling the capacity within twenty years? It takes a lot of preparations and bureaucracy (ten years) before you can start construction work I'm afraid.

And certainly not yet the predicted x2 or x3 capacity as predicted for the 2030 - 2050 timeframe. I was ten, my father explained me one afternoon Ohm's law ( from Germany if I remember well...) fuses, resistors, batteries. Lessons learned and remembered.

The importance of basic principles and above all: don't be afraid of common sense. The last ten years I sometimes thought: Robert, you are talking to a brick wall. As soon as you dare to ask questions about the feasability of all these "everything electric" dreams you are considered to be a petrolhead, someone who doesn't like the green future, who wants to continue to destruct our planet. Or is afraid of electricity...That puts an end to discussion, you don't embrace our ideas, so you are our enemy.
