I lifted this graphic out of a very detailed analysis of the VW ID.3. The takeaway here is how important aerodynamics still are, especially compared with battery losses.

Not only are EV drivetrains less complex but they are more modular at subassembly level than ICE. We already see that batteries are being replaced as entire assemblies, same applies to the motor, gearbox, on-board charger and inverter, the only other essential components. These are literally...

Most EVs will charge at 7.4 kW on that, others less. It's absolutely massive for being hardly anything more than a GFI and place to hang the cable. AC "destination" chargers are fine for locations where you're staying overnight but outside a shop it's hardly worth the effort of plugging in...

Probably what it needed the most, not that I've ever seen one, lol! GM needs to stay competitive in this compact segment and there's nothing wrong with the engineering of the Bolt in my view (thanks to Weber Auto's teardown videos). Hyundai/Kia are continuing with facelifts of the similar-sized...

Each cell still only sees a low voltage, typically in the range of 3.15 to 4.15 V.

It is a good test and note that the reference time is that of an essentially-gasoline powered car. The best performers are either 800V cars or Teslas with their very effective battery cooling allowing fast charging rates. But even EVs in the lower half of the range remain fully relevant when...

I think it's only common with Type 2 AC charging, meaning almost everywhere outside of N.A. The 'charger' (EVSE) is referred to as "untethered" with a maximum of 32A per phase. It's less expensive to install this type and there's no cable to maintain. Many EVs come with the required cable to...

Correction, CCS Combo can now do 500 A. So, 500 x 800 = 400 kW. We’re just about there already.

The CCS Combo connector can only support 200 amps and that is the limitation 800 V gets around. At least for now ...

No, of course it doesn't. We're seeing a journalist trying to be an engineer. The safety present in EV charging systems is already much better than many if not all other electrical systems a person might encounter maliciously or otherwise. The battery potential in an EV is entirely isolated...

No only that but the reference to 380V leaves me puzzled. Does the author not understand the concept of power conversion? 800 V architecture makes sense as a standard just because of the cost savings in the vehicle and the potential of faster charging within the CCS connector current limits.

Even though the screen said 83 mph it also appeared to be frozen. He didn't pass the truck all that quickly. But he certainly was calm about the whole situation, all credit to him. It seemed like the charge port opened or indicated that it was open and that put the system into some kind of...

Yes, the gist of what I was trying to imply is that the brake booster may be a completely self-contained system running off 12V. It sounds like other CAN-based controls were frozen. The screen seen in the video doesn't seem to be updating with traffic. Right, my Kona EV can do much the same but...

One day at work in 1982 I was called over to look at some 6" dia white metal journal bearings that had just been removed from a fairly large hydraulic dynamometer that was undergoing a QA test. They spin-test the dyno in reverse because the drag due to the air inside would require more...

That dog has not only finished hunting but has gone back home already. Your lack of understanding doesn't change the facts. But I'll concede that EVs won't ever fix your worsening extreme weather and droughts. That's yours to own.

I understand Tesla brakes are relatively simple, just an electrically-powered booster as a substitute for vacuum. Not at all like the complex blended regen/hydraulic systems that every other EV has, as best as I'm aware. The latter allows the EV to be driven like a normal car (with a normal...

The driver seemed legit in the video interview. Talk about a "corner case," software wise. I'm sure Tesla will figure it out. Exactly what came to my mind since I once lived near the I-52 in San Diego. The driver had held the brakes down and they were found to be completely burnt out.

Yes, Bjorn Nyland got a test ride in a Kia EV6 GT which he measured does 0-100km/h in 3.5 seconds and 100-200 km/h in 9.3. And it can regen-brake momentarily to 350kW.

Perhaps study the reasons behind that?

I'm just stunned that Hyundai were are to come up with such a cool design that stands out from everything else.
