Commented On: Boeing 787 Battery Safety Updates: What Changes Were Made?


Green Car Reports 0 Views 10 comments
They never did find the smoking gun or "root cause" and their changes won't help at all. We did figure out what happened and it is a trivial fix. But we can't find anyone to listen. A lot of pressure to get back in the air with this fix as it is $50 million a week while down.

Kind of amazing. Very simple fix. They overlooked something VERY basic to these batteries.

Commented On: Despite Pollution, China Still Isn't Committed To Electric Cars


Green Car Reports 0 Views 9 comments
I rear the Chinese reluctance is a bit more mundane than all of that.
They are HUGE in electric bicycles and electric scooters. But electric cars are really not making it.

It is not the electricity. Not the range. And not the price of the cars.

It's the garage. Very few Chinese live in a house with a garage. Miles and miles of high rises with apartments.

You can take an electric bicycle or scooter in the elevator with you and up to your apartment. You can charge there and it won't be stolen.

What do you do with an electric car?

Commented On: Electric-Car Efficiency: Forget MPGe, It Should Be Miles/kWh


Green Car Reports 0 Views 43 comments
First, it can't be MPKwh. That's because it is not Kwh. It's kWh. The W is capitalized after the originator of the figure of measurement - Watt.

So MPKWhor MpkWh or MPKWH but not MPKwh.

Second, there is nothing non-linear about it and it is an easy conversion.

MPGe/33.7 IS MPKWH - there being by the EPA definition 33.7 kWh per gallon as pointed out.

We don't actually find MPKWHr particularly useful. We like Watt hours per Mile. And so if you have 95 MPGe = 95/33.7 or 2.82 miles per kWh. This works out to 355 Wh/M.

This is fun because 10x Wh per mile roughly give you to the weight of the car.
355 Wh/M = 3550 lb car. If it is a HEAVIER car, it is quite efficient. If lighter, not so efficient.

Commented On: Tesla CEO Elon Musk Offers Help To Boeing On Battery Problems

Anthony:

You may have reported it. But the chemistry is NOT different than that used in electric cars. In fact, it is almost identical to the chemistry used in the NCR18650A and B cells from Panasonic that are used in the TEsla Model S.

Indeed the cells, and the chemistry, do not appear to be the problem. Once again, a well intended "battery management system" appears to be the culprit.

I think they would do well to use Musk's packs from the SpaceX. They undoubtedly already have FAA approval. That's the problem for Boeing. It's not finding a battery that WORKS so much as getting one APPROVED. particularly at this point.

So what happened to the MiniCooper E cars? What did they do with them after they were turned in?

Commented On: Electric-Car Conversions: Do They Really Stand A Chance?

I "got it" just fine. I think you kind of missed the clue. The DIY custom e-car thing is exploding - right now. The OEM thing actually IS a little bit of a setback. That is because they are FAILING so broadly. That gives all e-cars the black eye. They built the wrong car for the wrong buyers.

You will be further surprised to learn, that over half of our viewers that ARE building cars, already have a Leaf or a Volt or a Tesla. You see, the low hanging fruit the OEM's DID sell to are the SAME guys that have been intensely interested in electric cars all along.

There is a clueless element here - and it encompasses most of the OEM's, and apparently yourself as well.

We're doing great. We wish THEY would do great too.

Then you have two scenarios to pick from Antony. Either I'm just blissfully oblivious, or they don't pose ANY problems from the big name competition.

All they can cause is further demand for vehicles. They've been making cars for 130 years, and we still have a very active custom car industry worldwide - complete with huge trade shows, thousands of vendors, and millions of participants.

But your world causes you to get a little ahead of yourself. The OEM cars are entirely press releases. They virtually don't HAVE any cars.

The Leaf and the Volt are abject total marketing failures by ANY reasonable measure. Far too much of a price premium.

The Ford and iMiev are just coming online in numbers approaching the DOZENS. What problems?

Commented On: Is Tesla 'Bricking' Story Just An Angry Owner's Warranty Claim?

I'm with Max on this one. Leave it unplugged and TOTAL the car? That's crazy and it will cause a huge backlash against electric vehicles if it even becomes a RARE problem.

Tesla needs to sit down on this one, eat the $40K and come up with some way to disconnect that pack if it reaches a low point.

Commented On: Bricking A Tesla Roadster Battery: Today's Electric Car Meme

Actually, it's likely a problem with all electric cars. IT is very difficult to create them without some parasitic loads on them. And even tiny loads can drain down the pack if parked for weeks or months. Tesla is somewhat hampered in that it DOES tend to be a toy car, used infrequently anyway and often by the wealthy who have lots of cars. So this is a very real issue I would think.

We have a simple switch to disable the pack entirely if the car is to be parked for long periods. But we would have to remember to do so and or know it was going to be parked for long periods. Left to its own devices, it would indeed drain the pack and destroy it. And they are indeed expensive.

Commented On: U.S. Sales Of The Nissan Leaf Electric Car Now Over 10,000


Green Car Reports 0 Views 7 comments
I'm sorry. A target of 10,000 vehicles. The Nissan target for 2011 was much heralded in their own press releases in 2010. It was 150,000 units for the year. Not 10,000.

This was revised toward the end of the year 2011, a year later, to the 10,000 number.
