Jan 29, 2018 Several years ago, Georgia offered a generous state-tax credit
for purchase of a zero-emission vehicle, and its sales of electric cars
boomed. When state politics interceded to kill that credit in 2015—and add a
new tax specifically on those same vehicles—the state became a case study on

We already knew that battery-powered and electric planes were in works.
Recently, an electric aircraft has successful completed its first flight in
Australia.
Electric cars and trucks are old news now, as the future is moving towards
larger electric vehicles (EV) such as airplanes. Aircraft manufacturer
Pipistrel manufactured a single-engine, two-seater electric airplane named
Pipistrel Alpha Electro. The test flight was conducted in Perth.
The electric plane runs on two lithium-ion batteries, similar to those used
in Tesla's EV. The batteries help function the plane for an hour along with
30 minutes of extra power in reserve. As for their entire lifetime, the
batteries can provide almost 1,000 total flying hours for the plane. The
plane can be fully charged within an hour with the help of a supercharger,
reported Futurism.
The company is working with a local startup Electro.Aero to bring the
electric planes for normal use. Being safer and easier to fly, founder of
Electro.Aero expressed, Electric propulsion is a lot simpler than a petrol
engine. Inside a petrol engine you have hundreds of moving parts.
Furthermore, the plane is also cheaper than the conventional ones. The
engine of the EV costs around AUD 3 an hour one tenth the cost of a fuel
engine. It requires 60kW of power to take off and only 20kW to cruise; it
does that all without creating any noise.
Pilot Robert Bodley said, It's more comfortable. The vibration is less, the
heating is less, it's a more stable aircraft as well.
By mid-January, local pilots will be start to train for flying the electric
plan, and registered pilots will be needed to complete a familiarization
flight before flying it independently. ABC News reported that the company
plans to build charging stations for electric panels to the solar array.
Also, in future, electric air-taxis will also be seen in skies carrying up
to five people.

Internal combustion engines have been around for about 140 years. In that time, we've become fully versed in all their nuances. We can chat with our pals about compression ratios and horsepower and valve timing. We know the advantages of displacement and the efficiency of turbos. Car meets quickly turn into oceans of popped hoods. Even the most cutting-edge engine tech in the latest hypercar is parsed out thoroughly in the automotive media. We know engines. We talk engines. We love engines. We don't love motors, though the electric ones, that is. You know, the ones that have been around for almost 250 years and were powering cars in the 1880s, until gasoline engines overtook them due to their range and speedy refueling. (One of the first alternating-current induction motor inventors: Nikola Tesla.) Our collective and virtually absolute lack of knowledge of what actually drives the wheels of all the new electric vehicles on the roads today is, indeed, puzzling. How bad is this problem? Most EV owners probably don't even know where the motors are in their cars, or how many there are, or what they look like. Making things worse: Technical information is scarce, and mostly found only in forums and niche technology sites. Consider, as well, the fact that our own Alex Roy just reviewed the brand-new Tesla Model 3, and in the course of 4,000 carefully-crafted words, didn't mention the motor once. Not that you could blame him: The Tesla Motors page on the Model 3, which includes a specs section, itself makes no mention whatsoever of the motor. Furthermore, the company's own application to the EPA last year for the car's Certificate of Conformity dedicated 250 words to describing the battery, but just 20 to the motor. (It's a 3-phase, 6-pole AC internal permanent-magnet motor producing 258 hp or 192 kW and 317 lb-ft of torque, in case you were wondering.) Similarly, Chevrolet's page on its new Bolt EV makes no reference to the motor except to say that the car has an electric drive unit. Even BMW a company that literally has "motor" for a middle name only deigns to reveal on its i3 product page that the motor is AC synchronous. Meanwhile, the engine in the base-model 3 Series a few clicks over is described as a 2.0-liter BMW TwinPower Turbo inline 4-cylinder, 16-valve 180-hp engine that combines a twin-scroll turbocharger with variable valve control (Double-VANOS and Valvetronic) and high-precision direct injection. That's before the site goes on to describe the engine's electronic throttle control, auto start-stop function, direct ignition system with knock control, electronically controlled engine cooling (map cooling), brake energy regeneration, and driving dynamics control with Eco Pro, Comfort, and Sport settings. Among reviewers, Roy is far from the only one to give the motor short shrift. Most EV reviews gloss over that key part of the tech, except to note its relative quiet, its torquey response, and its simplicity and long-term low maintenance requirements. Most of the space dedicated to the powertrain focuses instead on the battery how big, its construction and composition, where it sits, how much range it has, how many days it takes to fully charge, and so forth. But then, it's hard to blame people for not giving a damn. Most consumers hell, even car geeks don't possess the knowledge or vocabulary to authoritatively converse about electric motors, and on the surface, there would seem to be precious little indication that there's even anything meaningful to discuss about them. It's a lot harder to get excited about, say, the difference between permanent magnets and AC induction than it is between V-8s and twin-turbo sixes. The fact that carmakers and the media don't billboard motor innovation naturally leads the public to assume that there's nothing much going on there. Except...that's just not true.

Re: [EVDL] Question: EV with a 110v outlet with 2KW power rating?
I used to have a 30 ft 6AWG extension cord to bring the stove outlet to the driveway. Only once was it needed to give a guy a charge that had the Saturn with ACPropulsion drive that could charge at up to 80A, so I asked him to crank it up to 50A and within the hour the 12kW charge rate caused his batttery to hit max voltage and start tapering while my house circuit was cold as stone, so everything worked as designed. I believe it was the first time he cranked it up to that high level, normally he stayed below 40A. one fender was humming from the 60Hz magnetic field in one motor winding. In preparation of more electric loads and solar, I have brought a 50A circuit from my service panel to a load center in the garage, so it is now much easier to add stuff like for example a 50A charging outlet or a circuit for a solar inverter.

I think no power is provided. (That's fairly standard at farmers' markets in Los Angeles, something I'd like to change.) I think this event will be in a public park. In any case, I was told we would need a generator just for the bounce house, so I'm trying to find a replacement to power just that one thing. > If there is a solar setup, even if it does not produce the required 1kW, > can you have the panels charge (a set of) batteries that run the inverter > to power the bounce house blower? > That would send a powerful message of having fun on solar power, even if > not *all* the power is coming from the sun at that time - as long as you > can supplement the power that is needed, > no point in "ruined fun because the sun dd not shine".

Indeed. Status: - Nichicon confirms they don't have a US model of the portable cademo -> 110v unit yet. - I'm talking with the guy who put solar on my roof; he also offers batteries now (I gather Tesla PowerWall 2 and Sonnen Eco). I have no idea if it's practical or wise to try to use one of those for this application, but I could imagine lugging one of them over charged, and using a panel or three during the day -- to show power going in, if nothing else. Anyway, even if it's not, we could put up a solar panel in front of the gas generator :-) - Dan ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

Re: [EVDL] Question: EV with a 110v outlet with 2KW power rating?
Dan, For the use with your 2013 Leaf, you would either - need to stay below ~80A from the 12V battery, so below 1kW - tap into the high voltage yourself - find an affordable CHAdeMO inverter, which seems to be an oxymoron as even the plug is excessively pricey - or find an external power supply that you transport with the Leaf. My earlier reply was taking as given your request to power the 1 - 2kW blower from an inverter (I suggested to use a cheap used UPS for this) and augmenting the UPS battery with the Leaf's aux battery and DC/DC converter continuous 80A charging. Another alternative is to avoid the (often horribly inefficient) AC solutions and find an efficient DC powered blower so you can stay well below the 80A at 12V and power it directly from the Leaf's aux battery. Even though it is relatively easy to access the Leaf's HV battery pack voltage and power the internal contactors from external 12V, I would not recommend this solution as it risks disabling your Leaf, besides obvious risks in dealing with HVDC. My previous EV truck had a 120V battery pack, for which I bought a cheap used UPS that came without batteries in the external battery cases, so all I needed to do was to wire its cord to my pack via the breaker that I also removed from the battery case and I could plug the UPS inverter into my EV pack for up to 3kVA of power. For the power at this green event, what is provided to other activities? If it is possible to run an extension cord then that is much greener than building a dedicated solution. If there is a solar setup, even if it does not produce the required 1kW, can you have the panels charge (a set of) batteries that run the inverter to power the bounce house blower? That would send a powerful message of having fun on solar power, even if not *all* the power is coming from the sun at that time - as long as you can supplement the power that is needed, no point in "ruined fun because the sun dd not shine". So, make sure that the additional energy needed (from your EV or from batteries charged and swapped out of needed) can support the power drawn for the bounce house during the whole period of the event. Success!

Hi all. question for the EV connoiseurs out there: I have a 2013 Nissan Leaf with a ChaDeMo port. Are there any portable V2G units that can plug in and provide 2KW of power? Alternately, are there any other EVs that support such a thing? I saw such a thing at a Nissan booth at a recent event. http://www.nichicon.co.jp/english/eco/pdfs/2012e_02.pdf but it didn't look like it was aimed at mobile use. And evidently they have a new system which would meet my needs: http://www.nichicon-us.com/english/product_news/new173.html but it's only available in Japan for now. The application is a bounce house at a green fair; evidently those need 2KW during inflation, and 1KW during operation ( see http://partytime-rentals.com/learning-center/bounce-house-power-requirem ents/ ).
