Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Making a prototype electric car is actually surprisingly simple for what it is, the problem is adding all the required active and passive security systems and passing the safety inspection for selling in the EU, not to say the usual about supply chain, manufacturing, etc, which will probably be quite difficult given this goes against every automotive company's interests.
A simple, repairable EV would be my dream car but unfortunately I don't see it happening soon in Europe.

Well, it's probably not coming out of the US, Russia, or China sooner.
My Nissan Leaf is currently bricked because a charging station sent the wrong communication messages (or the right messages in the wrong order, still don't know exactly what happened).
The car thinks there is a cable still plugged in (when there isn't), so it won't go into drive. It also won't recognise a new cable being plugged in, so it won't charge. It doesn't think there is a charging session ongoing, so there is no way to stop it. There are no fault codes and no errors. The car is behaving perfectly normally except that it won't start.
Nissan has no idea what the problem is. Multiple experts has tried with success to find anything wrong. It's been 3 months and the best option so far is to start replacing modules (for more than the value of the car) until we accidentally replace the correct module.
The vast majority of the problems we're having is caused by a lack of information and communication from Nissan. They don't provide circuit diagrams, or diagnostic manuals, and they don't even permit people to buy the diagnostic tools they use.
An open source, repairable car would be really nice about now.
shit like this is exactly why I won't buy a newer car, even an economical option like the Leaf
I want simplicity and reliability and repairability. these incredibly complex modern vehicles don't have that
and it's not like I'll be buying them ten years down the road when there are no options left - I will find something that meets my criteria, and I will pay more for it. black box cars do not make good used vehicles, and they will be priced accordingly by knowledgeable buyers
It's sounds bizarre to me that this couldn't be resolved by rebooting.
Then again, how do you reboot a car exactly? It's not "off" even when the car is not started I suppose.
You perform a battery reset of the low voltage system. Disconnect HV system, disconnect the 12V battery (or batteries) then short the positive and negative battery cables together for about half an hour. Then reattach 12V battery, and then turn HV system back on. Forces all the computer modules (normally about 30-50 modules in a modern car) to reboot from their base programming. Have to do this several times a week, often fixes weird electrical issues.
then short the positive and negative battery cables together for about half an hour.
Uh, on the pcb side, to discharge condensers & co. Not on the battery side.
I've tried disconnecting the 12V battery. I believe the technicians have tried disconnecting the 12V and HV batteries at the same time. All factory reset buttons have been pressed. We've tried plugging in a CHAdeMO and type 1 cable at the same time.
I'm also very surprised that something like this could be software related and persist across power failures/reboots.
The shotgun approach to repair is a tried and trued method of wasting money.
Or making money. Depends on which end you are on.
If they have zero ability to debug the fuckers with multiple of them bricked then this is good information for all of us.
Nissan is clearly too stupid to buy from.
The main reason I am not buying into electric vehicles is the state of reliability and repairability and the immense black box which those vehicles are nowadays. What I would like to see is pretty much exactly that prototype as a commercially available and street legal product. Where everything can be modified and improved or repaired by anyone. Just like in the "good old days"...
Sounds like you're not buying ANY vehicles nowadays
Modern ICE cars aren't really any different in that regard.
It's absolutely absurd that that isn't the norm.
Across all industries. Look at a company like Framework, there's no reason everything can't be made like this.
We have customers that can’t figure out how to turn their headlights on, or fill the washer fluid. “Repair yourself” needs to be a pretty low bar.
Not really - being easy to repair also means that its easier for shops to repair, which is becoming a problem lately as companies are purposefully making it harder to service EV's outside of their designated facilities.
Good point.
I worked a summer in a garage. I lost count of the number of "strange noise like something rolling around the truck" orders, resolved by removing the thing rolling around the trunk. I was 17, amazed these people had jobs and money to buy cars.
SlateEV is self-repairable. It's one of those things super popular on Reddit, but no one in the real world knows which end of a screwdriver to hold.
Yup. We get cars towed in because they ran out of gas.
Ok, but what is "no information" supposed to mean? Why does it not say "empty"?
It did show empty. It has a normal gas gauge, plus underneath the gauge, it shows the mileage till absolutely empty. When you hit 0 km remaining, it will switch to three dashes, indicating you are absolutely, completely empty, as in out of gas typically in less than a km. The gauge was reading empty, and underneath was showing the three dashes. That is what the customer interpreted as “no information”.
People like that are why I support public transit and walkable cities.
Cars are appliances to them, and since they’re most of the car market most cars suck.
By getting people off the road who don’t want to be there the demands of the car market will change and maybe we’ll have cool cars again.
Plus we can increase driving license and maintenance requirements so that people know to stay in the right lane and don’t have parts falling off their cars.
And since we need fewer roads we can build them better and maybe, in some places, we can have no speed limits.

Most of the world has annual safety inspections. Not North America.
We have annual inspections in my state and I still got a lug nut chucked into my windshield.
Where in North America are there no inspections? I can’t renew my registration without the car going through inspection and I assumed inspections were required everywhere.
Kentucky...
Most places in North America. Most places here in Canada only have inspections when the vehicle changes owners. In Quebec, the inspection is only done when you buy a car from a dealer or used car garage, does not apply on private sales. Some seriously sketchy cars in Quebec.

Ontario. And no visible licence validation either. Doug Ford put all the drunks and uninsured losers back on roads.
California has inspections never.
I’ve never had to get a vehicle inspected in Wisconsin as far as I can recall. There are some areas that do emissions testing but that’s about it.
I once had a car where you couldn't change a frickin' lightbulb without dismantling half the motor. Nowadays "repair yourself" really has a very low bar.
The driver’s side lightbulb on my wife’s Kia Soul is largely blocked by internal components. I found some instructions explaining how to remove the front bumper for access. Fortunately some guy on YouTube made a video showing a better way. Need to make some marks on parts so you can line them up properly when putting it back but with some tight contortions it was possible and only took a couple minutes.
A lot of modern car headlights are LED which you shouldn't need to change like old bulbs. At least not often.

I would buy it. :)
Story: I drive a Mitsubishi electric car of generation 0 (MIEV). They have a typical error: a high voltage comparator on the motor controller breaks, stopping the car. The fix involves 1 resistor, and works (you just need dwarves with titanium hands to reach the correct part in less than a whole day). The resistor costs cents. Authorized representatives propose swapping in a 5000 euro motor controller (the remaining value of the car is about 1000 euros).
Easy maintenance is an absolute requirement. Otherwise expensive cars become junk.
The should create a system of interchangeable parts! A breakthrough
Are there plans to produce ARIA commercially? (All i saw in the article is about the prototype) Looks like a DIY Honda CR-Z, in a good way.
There was a cool Sono Sion project, a smallish boxy EV that comes with a repair manual, solar panels for topping off the battery, and power-sharing mechanic to power another EV or a home. But they either ran out of money or could not set up manufacturing.
