The police department in Geneva, Switzerland, will be the first law
enforcement agency to use the BMW i3 as a police car.
The BMW i3 Police Car will replace next month the BMW X3 Authority Vehicle.
With a population of less than 200,000 people and an area of 5.93 km2 (6.15
sq mi), Geneva is the perfect small city to use the megacity – see what I
did here? – as a highly efficient police vehicle.
Without a doubt, other European cities will follow so the BMW i3 might have
a new use for itself.
The i3's electric drive-train generates output of 125 kW/170 hp and peak
torque of 250 Newton meters, which is immediately available from a standing
start. The BMW i3 sprints from 0 to 60 km/h in 3.7 seconds and from 0 to 100
km/h in 7.2 seconds. Its top speed is limited to 150 km/h for efficiency
reasons.
The US EPA says the i3 has a range of 81 miles with a combined MPGe of 124
(138 MPGe City, 111 MPGe Highway).

[EVDL] EVLN: Tesla-D ?Dual-Motor AWD Model-S?
Musk teaser tweeted Tesla 'D' and something else on 10/9 http://www.pocket-lint.com/news/131243-tesla-has-an-event-next-week-at-hawthorne-airport-here-s-what-it-might-show-off Tesla has an event next week at Hawthorne Airport: Here's what it might show off By Elyse Betters [20141003] [image http://cdn.pocket-lint.com/r/s/628x/assets/images/phpwzb3vc.png (both tweets) video http://www.youtube.com/watch?v=EJmhpgW0Dmc (Autonomous EVs) ] Tesla has an event next week at Hawthorne Airport: Here's what it might show off Electric car maker Tesla is getting ready to introduce two new...things. The company is holding event on 9 October - at an airport of all places. It is expected to show off the D and something else. Seriously. If you're curious about all the showmanship and mystery, keep reading. Pocket-lint has rounded up the rumours and speculation, in an attempt to uncover what the D and that something else might be. What is Tesla? Tesla - technically referred to as Tesla Motors - is a US-based public company that makes and sells electric cars. The car maker's first vehicle was the Tesla Roadster all-electric sports car, followed by the Model S sedan. Tesla in 2012 also unveiled another electric vehicle, called Tesla Model X, with plans to launch the crossover in small numbers by end of 2014. And finally, Tesla is developing a third-generation car, due out after Model X, called Model 3. It was originally codenamed Model E. Elon Musk, the founder and CEO of Tesla Motors, said he had planned to name the next-generation electric car Model E so that Tesla's three car models - including the Model S sedan and Model X crossover - would spell out “SEX. Ford killed that idea however when it threatened to sue Tesla over the Model E trademark. When did Tesla first tease the D? Musk tweeted on 1 October about Tesla's plans to announce new things on 9 October. The tweet included an image of a dark-coloured vehicle parked inside a shadowed garage, with the garage door showing the letter D. Musk's tweet with the image stated: About time to unveil the D and something else. His followers of course translated the tweet into a sexual joke of sorts, which forced Musk to tweet the following just a few hours later: I love the Internet. Comments had me literally ROFL. No, it wasn't intentional. Glad I didn't mention the other letter! Nevertheless, Musk teased that Tesla had two things to unveil. But he didn't say where. Where is Tesla unveiling the D? Tesla Motors sent invites to a press event on 9 October near Los Angeles, presumably to unveil the D that Musk tweeted about the evening before. The event is being held at Hawthorne Airport. And so the question now is: what is Tesla unveiling and why is it using an airport as an event space? While we can't yet speculate about why Tesla chose Hawthorne Airport, we can tell you what Tesla might show off. Keep reading to learn more. What is the D? The D is rumoured to be a new vehicle in Tesla's lineup. The D could stand for a dual-motor, all-wheel-drive version of the Model S. The Verge spotted in a Tesla forum a picture of an unknown Tesla with the model tag “Model S P85D (as seen below). Tesla already makes the P85 performance version of the Model S, so it is not far-fetched to think the D might be another upgrade. The D could also stand for Driver Assistance. Tesla's recent software updates, as noted by Electrek's Seth Weintraub, have included land departure and speed assist features, which might signal that Tesla is embracing automation. That said, Musk told CNNMoney on 2 October that Tesla will unveil self-driving cars in 2015. Google and other companies have been developing autonomous vehicle technology for years, but Musk claimed Tesla already developed a mostly-autonomous car. He said next year's Tesla car will likely be 90 per cent capable of autopilot... like so 90 percent of your miles can be on auto. During the interview, Musk did not specify whether the self-driving Tesla car is the D or if it is the other mystery product he's planning to unveil. What is the something else? Going back to self-driving cars for a moment, it is possible that Tesla could unveil a dual-motor AWD Model D as well as show off its early efforts at self-driving technology. The phrase something else presumably implies a less significant product or maybe even something that's not yet finished. Like an autonomous car. Reports have also speculated Tesla could unveil something totally different, such as an electric motorcycle. The Street, for instance, quoted a senior analyst at Kelley Blue Book who predicted Tesla might unveil a truck or van at its 9 October event. Keep in mind none of these rumours or predictions have been confirmed by Tesla. We just have to wait and see what the car maker does next.

http://www.kansascity.com/news/business/article2363510.html Electric truck maker in Riverside revs up By STEVE EVERLY 09/30/2014 [image http://www.kansascity.com/news/business/26mmz9/picture2363509/alternates/FREE_768/OrangeEV%20al%20091814%200123f.jpg Mike Saxton (from left), Wayne Mathisen and Kurt Neutgens, all with Orange EV, conferred near one of their electric trucks at the company’s headquarters in Riverside. Orange’s trucks are former diesel models retrofitted with electric motors.ALLISON LONG/The Kansas City Star ] Kurt Neutgens worked 17 years at Ford Motor Co., including time as engineering manager for Ford’s F-150 pickup truck, but his dream was to someday develop an electric vehicle. So when Ford offered buyouts in 2006, he jumped at the opportunity. He went on to create in his garage an electric-powered Mustang, only to discover that the car was too expensive to make a business out of it. But now he believes things have fallen into place. Recently standing outside the offices of Orange EV in Riverside, a company he co-founded, Neutgens greeted potential customers who wanted to test drive the company’s electric truck. And he’s more convinced than ever that electric vehicles have a big future. “To me it’s the end game when it comes to transportation,” said Neutgens, who is president and chief technology officer of the company. Kansas City, of course, has a much higher-profile electric truck maker, Smith Electric Vehicles. But Neutgens’ company means Smith isn’t the only game in town. Smith Electric got more than $30 million in federal grants and plenty of publicity before it suspended production late last year. Its future is unclear as it seeks more funds. Orange EV has been operating more quietly since starting in 2012. It didn’t tap federal grants and moved carefully to build a prototype and test it. Now, it’s seeking buyers. Its first product is an electric terminal truck, built to pull loads of freight around places such as railroad yards and distribution centers. Orange EV completely refurbishes older terminal trucks, including a coat of new paint. The diesel engines are replaced with the motors, batteries and other components needed to make the vehicles electric-powered. “Essentially, we’re a manufacturer of industrial strength vehicles,” said Mike Saxton, Orange EV’s chief commercial officer. The vehicle has been getting some good reviews. A two-week demonstration at the BNSF intermodal freight facility in Gardner had the truck pulling 80,000-pound loads with enough power for 10 or more hours of work without a recharge. “We needed to see if Orange EV’s all-electric terminal truck could do the job and get through a shift on a single charge,” said Ron Teague, a senior vice president at ITS Technologies and Logistics, which runs the facility. “They’ve convinced our team.” The next hurdle for Orange EV is getting orders. The company has been in talks with ITS and other potential customers. It’s also holding events for test drives in Riverside. It can be a tough sell. Fleet managers often flinch at the higher up-front price for an electric truck, even if fuel savings and less maintenance make the trucks a good bet over the long term. They’re also pretty cautious when considering something new. A good market for terminal trucks is the Port of Los Angeles, which has about 4,000 trucks. About a quarter of them are alternative-fuel, but they run on natural gas. The rest are diesel-fueled, although with cleaner-burning engines than were once available. A few electric trucks have been used there in a trial, and they are viewed as having a lot of potential. But no decision has been made on whether to make a larger deployment. “They have made great strides in six to seven years,” said Phillip Sanfield, a spokesman for the port. But Orange EV believes the time is right, especially in locations such as distribution centers and rail yards. Wayne Mathisen has been a manager at Sprint, Embarq and CenturyLink in jobs ranging from financial management to leading a team that oversaw a fleet of 10,000 vehicles. He studied the prospects for Orange EV and decided to be a co-founder. He’s now the company’s CEO. “I fell in love with the plan,” he said. Mathisen said eventually the company could could build new and different types of trucks. But for now the focus is on refurbished terminal trucks, which can make a convincing economic case. Terminal trucks are used intensively, so the fuel savings mount more quickly. He declined to disclose the truck’s purchase price but said fuel savings along with the lower maintenance costs provide a payback of four to six years. The payback is even lower if the purchaser takes advantage of government incentives that will reduce the price of the truck. Those incentives vary across the country. Chicago has especially good incentives that could bring an Orange EV down to the price of a diesel truck. “We’re optimistic we’ll get our first customer this

]
What’s the buzz about electric? In LRO’s June 2014 Steve Hoare leads the
charge to find out.
What's the story?
The news that there was an electric Land Rover in the USA immediately made
me think someone had spotted a development mule vehicle from Land Rover’s
current line up. Imagine my surprise when I find out that the vehicle is
actually this 1951 Series I 80in!
The previous owner, Bill Moore, found the 80-inch in New Mexico, where it
appears to have spent most of its life. It was complete but tired, including
the 1.6-litre petrol engine. Bill’s goal was to give the Land Rover a
sympathetic restoration. After a year, the Series I was ready for a new
lease of life – then everything changed. Bill’s wife insisted that he needed
to cull some of his Land Rover collection, so he decided to donate the 80in
as the grand prize in an auction for the sustainable energy group on
Nantucket Island. In addition, the scope of the project had changed – it was
to become a fully electric vehicle.
The engine was removed and put to one side, leaving the engine mounts in
position. All the components for the Series I were already available off the
shelf from EV America. The only special item required was to design and
manufacture an adaptor to bolt the electric motor to the four-speed manual
Land rover gearbox.
The 12-volt DC motor, a Warp 9 was bolted to the existing engine mounts and
the special adaptor allowed the new powerplant to be bolted to the original
main gearbox. Twelve 6V 255 amp batteries were called into service to drive
the new motor and provide drivable performance and reasonable range, located
throughout the vehicle to spread the weight.
On a full charge travelling at a reasonable speed you can expect to drive
for around 50 to 60 miles, or three to four hours. The range can be quite
easy to extend – just add more batteries!
Our favourite bit?
If you step on the throttle pedal enough, it can throw you back, reminding
me of when a plane takes off. With the low-end acceleration of a jackrabbit,
the confidence builds and I yearn to unleash the power and blow the doors
off a supercharged Range Rover, and so quietly that the driver hardly
realises what is happening!
The whole ride is super-smooth and super-quiet. There’s no rumbling engine,
no fumes and no noise. The only evidence of mechanical motion was the main
gearbox gears meshing together and the occasional creak from the leaf
springs.
And the verdict from LRO writer Steve Hoare?
‘Sitting in the driver’s seat I’ve no idea how this vehicle will feel on the
road. Will I miss the rumble of the exhaust and the throbbing or valve
clatter vibrations of a reciprocating engine? What about the smell of
incompletely burned hydrocarbons and exhaust fumes percolating into the
back?
With the ‘ignition’ on and battery indicator showing maximum bars I press
the accelerator pedal. This is so much nicer than a gas-guzzler. This is
awesome! I step on the throttle, or maybe I should say, step on the
electricity, and a smile immediately lights up my face. The quick and
powerful, yet quiet acceleration is stunning.’

we must admit that Tesla has been a quite a mover and shaker for the
EV-cause which has helped turn the public's view of plugins around in a
positive direction.
Therefore during my afk stint (absence), I ask a few to monitor this
announcement and post what is released to the evdl so that we can know
what it is all about as well as a historical record on the several evdl
archives for the public to find and use.
Usually automakers make the announcement in an EST time frame, but don't
be fooled into being the first out-the-gate with what you find. I have
found that it is usually better to follow the announcements (the
newswires will be flooded with this topic for a while) for a few hours,
and pick the ones that have the most useful information, rather than the
first one to come out that usually are full of opinion and less actual
info.

Tesla has an event next week at Hawthorne Airport: Here's what it might

Electric car maker Tesla is getting ready to introduce two new...things.
The company is holding event on 9 October - at an airport of all places.
It
is expected to show off the D and something else. Seriously. If you're
curious about all the showmanship and mystery, keep reading.
Pocket-lint has rounded up the rumours and speculation, in an attempt to
uncover what the D and that something else might be.
What is Tesla?
Tesla - technically referred to as Tesla Motors - is a US-based public
company that makes and sells electric cars.
The car maker's first vehicle was the Tesla Roadster all-electric sports
car, followed by the Model S sedan. Tesla in 2012 also unveiled another

originally codenamed Model E.
Elon Musk, the founder and CEO of Tesla Motors, said he had planned to
name
the next-generation electric car Model E so that Tesla's three car

Ford killed that idea however when it threatened to sue Tesla over the

When did Tesla first tease the D?
Musk tweeted on 1 October about Tesla's plans to announce new things on 9
October. The tweet included an image of a dark-coloured vehicle parked

His followers of course translated the tweet into a sexual joke of sorts,

Tesla Motors sent invites to a press event on 9 October near Los Angeles,

Two things jump out at me. First, I'm thoroughly sold that right now is the time for large heavy-duty fleets to switch to electric. They're the ones with the long-term budgeting; municipalities, for example, pick bus models by building spreadsheets with five-, ten-, and twenty-year total-lifecycle costs. Something that costs twice as much to acquire but costs half as much over five years is going to win out unless it's actually unable to do the job. And big vehicles are going to need lots of big batteries, which will do absolute wonders for driving the whole economy of scale thing. They're still going to be looking for the best energy-to-everything-else ratios; shaving 1000 pounds off a pack for a ten-ton vehicle is going to be as important as shaving 100 pounds off a one-ton vehicle, and same with volume and price and anything else. The vehicles are just going to have ten times as many batteries -- which, in turn, means that every single big vehicle purchase is going to create as much demand from the battery manufacturers as ten econoboxes. An entire fleet of 100 big vehicles is as significant, therefore, as a thousand econoboxes -- quite the economic force multiplier! The other thing that struck me was that offhand remark about an electric-powered Mustang. The day that the first Mustang EV rolls off the Detroit (or wherever) assembly line is the day that we can be certain that there is no more future in petroleum-powered passenger vehicles save as novelties. Anybody want to take any bets on when that'll happen? I'm thinking probably a decade at least, but probably not much more than that. Cheers, b -- next part -- A non-text attachment was scrubbed...

People who love their farms, care about the farm animals and protect the soil for future generations have been replaced with large agribusiness farms and Contained Animal Feeding Operations (CAFO). The loss of the personal touch of the dedicated farmer at the expense of fossil fuel based methods of growing crops and animals has increased yields while damaging land, waterways and lives... The average US farm worker has a life expectancy of just 49 years. -- Pat Murphy Jan Steinman, EcoReality Co-op ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)

Re: [EVDL] DC-DC Cooling
Wow. I had no idea. Don't suppose you could run your brakes and steering from mechanical pumps coupled to your drive motor? That would be more efficient, and save you a bit of range. That's what I plan to do in the conversion I'm working on. I agree with others that the parallel Vicor modules may be fighting with each other. Are they adjustable? If so, you could sum them via a Schottky isolator, but it will drop about 0.2 volt, which you'd probably want to adjust out. If you can't find Schottky isolators, you could sum the outputs via small resistors. 5 milliohms would drop only 0.2 volts at 40 amps, and would balance the load on the modules. Or you may want to can the parallel module concept, and use a single converter rated for the amperage you need. That's the most expensive option, but the other options all require more effort.

Risk Assessment in the hands of centralized corruptible agencies is no protection for consumers as the disease and health epidemic in the U.S. linked to over processed, industrial foods shows.

[EVDL] DC-DC Cooling
On Mon Oct 06 16:21:01 PDT 2014 ev@lists.evdl.org said: I think I'm going to have to figure out how to water cool my DC-DC. I built this one using 4 Vicor 20A bricks to get a 80A capable unit. It all fits on the back of a 6 square 2 thick heatsink with a 6 fan on it. I'm noticing that when I'm running 40A continuous load, the output starts becoming erratic. Ther fan on the heatsink doesn't seem to be enough when I'm drawing a lot of 12V power. (blower, lights, brakes, etc..) I found at least part of the problem. The bolt on the common 12v ground had come loose. this meant that EVERYTHING had a flakey ground connection, as that is where the battery, accessories, dc-dc, are all tied together. I've also found a bad connection on my 12V Ammeter, so that is part of the reason it was jumping around. Still need to do more testing, as I was noticing that the voltage drop across the fuse on 1 of the 4 Vicor bricks was MUCH higher than the others. (like .5V vs .1v) Fuse didn't blow though. -- Tigers prowl and Dragons soar in my dreams... ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)

Ah, I think you pointed out the issue: the brake vacuum pump. Here is what I suggest: get a hand-held IR temperature measurement device, and then while everything is running (include the vacuum pump) check for heat on the modules. Also, measure the total current when everything is running. I looked at a lot of Vicor bricks, and they are good up until you get near 90% max - then they heat up. Good luck!

That would be more efficient, and save you a bit of range. That's what I plan to do in the conversion I'm working on. Somehow, I doubt that running the brake vacuum pump continuosly, when it's not needed, is more efficient. As for the Power Steering pump, generally you need the most power from that when you are moving the slowest. Mechanical ones are always pumping fluid, and just letting it flow back into the reservoir. Hardly efficient. The 12V one only draws a few amps when idling. I agree with others that the parallel Vicor modules may be fighting with each other. Are they adjustable? If so, you could sum them via a Schottky isolator, but it will drop about 0.2 volt, which you'd probably want to adjust out. Already doing that. Actually, I'm seeing a bigger voltage drop across the 30A fuse on each module than I am across the diodes. -- Tigers prowl and Dragons soar in my dreams... ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
