In the past, when I've looked at such things, they were about as expensive as buying an EV, and tended to offer far shorter range and no regenerative braking.

Missing regen braking doesn’t even make sense, that can’t be THAT hard to implement in a controller

[-] bluGill@kbin.social 8 points 11 months ago

Depends on what motor they use. Some get weird. The people I know who coverted a car didn't try for regen because their surplus motor was wound in a way that makes regen really tricky, and you don't want to get this wrong.

[-] skyspydude1@lemmy.world 8 points 11 months ago

It's an extremely tricky thing to get right, blending regen and normal braking. It's going to be unique to each car, and getting it wrong makes the brakes feel absolutely awful.

for 15k€, a minimum of specs need to be guaranteed.

[-] Semi-Hemi-Demigod@kbin.social 14 points 11 months ago

I am highly skeptical but willing to be convinced. How do they handle mechanical throttle linkages and emissions ECUs? Does it go through you’re existing transmission and drivetrain?

"We take out the combustion engine and we have a frame which uses the old points of the engine," Timo Walden, project manager at e-Revolt and one of the company’s first investors, explained. "And so we can easily swap only the engine with the new frame and the components. And that's why we are much faster than an individual solution. So, the frame here is a big part of our fastness". The company says it usually takes on average around a day to complete the process, which includes stripping the old engine block out of the car and replacing it with its patented battery technology and engine frame, as well as the full digitalisation of the vehicle. Costing between €12,000 and €15,000 to complete the job, the price point may give some reassurance to many consumers who currently can’t stretch their budgets to buy a new EV.

Article too vague in that regard, but it seems such cars are allowed to transit on german roads, so assumingly they are safe to drive.

Wait. The battery AND the motor is only where the ICE was? What’s the range than? 40km?

[-] derphurr@lemmy.world 8 points 11 months ago

Pretty easy on modern front wheel drive only engines. The skeptical part is brakes, HVAC, alternator etc rely on combustion engine. So it's possible to fit Prius type hvac, not sure what you would do about rear braking, transmission interlock, security system, radiator core, a/c core....

You could keep factory brakes and some cars already have electric brake pumps, etc. Maybe fit electric vacuum boost.

[-] bluGill@kbin.social 4 points 11 months ago

Diesel engines don't generate vacuum so there are a.number of options off the shelf.

[-] Semi-Hemi-Demigod@kbin.social 4 points 11 months ago

Yeah, I forgot about all the systems that still use vacuum for power, too.

While i don’t know what their doing specifically, normally you replace the throttle petal and now pointless transmission entirely, and just make up new custom length driveshaft so your not at risk of mesing up anything safty critical.

The new EV components go on their own canbus network, and if they keep the dash they probably have a microcontroller playing translator between the two networks.

Costing between €12,000 and €15,000

It's honestly shocking to me that it's that cheap

[-] Addition@sh.itjust.works 8 points 11 months ago

I see they're dumping the engine but I wonder how they're handling the transmission. I bet it's probably a manual only conversion.

EV conversion has been a thing for a while, albeit not at this scale, and my understanding is that automatic transmissions just turn to sand against the torque of a singular big EV motor. That's why most dedicated EVs don't have transmissions at all in favor of wheel specific motors and SSR gears.

[-] iraq_lobster@slrpnk.net 8 points 11 months ago

someone needs to debunk the technicalities behind their 'conversion'. for 15k€ you would still get a second hand EV in good condition

[-] FartsWithAnAccent@kbin.social 6 points 11 months ago

Manual EV? I'm OK with that!

[-] Mojojojo1993@lemmy.world 5 points 11 months ago

Fantastic idea.

We should be using what we already have. Would love love love to convert everything to ev.

I've got a 2003 Golf. Could it be converted? Probably however 15k is about 5x what I paid for it. So unless they bring the price down considerably most will just buy new models. If you can remove the frame and drop the chassis onto an electric frame and keep costs down. That might be the way to go. Solid state batteries should also make a huge difference. I need 250 -350km minimum for it to make sense. Make it cheaper and force government to subsidize it.

Zero point making 8 billion people scrap their old cars and buy evs. Just pointless

[-] AlexWIWA@lemmy.ml 3 points 11 months ago

Hmm, tempted to do this to my old car.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
