The milestone of accomplishing the unthinkable electric 1978 Ferrari 308 GTS
— and, as it turns out, fastest — was made possible by the Californian based
company Electric GT, according to the news reported by CNN.
The Electric Ferrari created by Eric Hutchison is 10 seconds faster than the
original gas version.
“I really was dying to know how this 308 compared to a stock 308,” says
conversion specialist Hutchison of Electric GT.
Italian GP: Hamilton delights in spoiling Ferrari party
“We had a professional driver drive both cars in a timed environment on the
same track — about a mile and a half — and the professional driver did that
lap in 1:26 with a gas Ferrari.”
“The electric car absolutely decimated the gas car,” he said.
“Watching the professional driver off the line, the electric car left like a
25-foot burn out as he was just gripping for traction.”
The electric Ferrari is 10 seconds faster than the original gas version
It cost him $10,000 to buy from a junkyard after being destroyed in an
engine fire.

According to Hutchison the opportunity for speed was what made the car a
perfect vehicle to transform.
“The Ferrari makes a great candidate for conversion because when you’re
converting the car to electric you’re adding power, you’re doubling the
power, you’re doubling the torque,” he said.
“This car was meant for speed. It might not have been engineered for this
much speed, but it handles it really well. This car actually goes so much
better and it feels natural with this amount of power in it.”

https://www.eurekalert.org/pub_releases/2018-04/uarl-arr041718.php Army research rejuvenates older zinc batteries 17-Apr-2018 U.S. Army Research Laboratory [image / Artwork by Eric Proctor https://media.eurekalert.org/multimedia_prod/pub/web/168210_web.jpg An artist's conception of a zinc ion that has been fully surrounded by anions in the super-concentrated electrolyte is trying to break out of the binding and deposit on zinc metal surface in a controlled and smooth manner ] ADELPHI, MD. -- Army scientists, with a team of researchers from the University of Maryland and the National Institute of Standards and Technology, have created a water-based zinc battery that is simultaneously powerful, rechargeable and intrinsically safe. The high-impact journal Nature Materials published a peer-reviewed paper based on this ground-breaking research April 16. In prior achievements, these scientists invented a new class of water-based electrolytes that can work under extreme electrochemical conditions that ordinary water cannot, and have successfully applied it on different lithium-ion chemistries. In this work, they adapted the electrolyte to a battery chemistry much cheaper than lithium: Zinc, and they demonstrated that an aqueous battery can satisfy the multi-facet goals of high energy, high safety and low cost simultaneously. The world's very first battery used zinc as anode in 1799. In the following two centuries, many zinc-based batteries were commercialized, some of which are still on market. These batteries used to provide safe and reliable energy, although at moderate energy density, to satisfy our daily needs, but their presence in our lives has significantly shrunken since the emergence of lithium-ion batteries 28 years ago. Besides energy density, a major reason for the diminishing role of zinc batteries is the poor reversibility of the zinc chemistry in aqueous electrolytes. Non-rechargeable batteries already created significant amount of landfill, imposing serious environmental burden on industrialized societies. "On the other hand, with increasing presence of lithium-ion batteries in our lives, from portable electronics to electric vehicles, their safety raises more public concerns, from Tesla car fires to the global grounding of the entire Boeing 787 fleet," explained Dr. Kang Xu, who is an ARL fellow and team leader, and co-corresponding authors of this paper. "The safety hazard of lithium-ion batteries are rooted in the highly flammable and toxic non-aqueous electrolytes used therein. The batteries of aqueous nature thus become attractive, if they can be made rechargeable with high energy densities. Zinc is a natural candidate." The researchers said the new aqueous zinc battery could eventually be used not just in consumer electronics, but also in extreme conditions to improve the performance of safety-critical vehicles such as those used in aerospace, military and deep-ocean environments. As an example of the aqueous zinc battery's power and safety, Fei Wang, a jointly appointed postdoctoral associate at UMD's Clark School and ARL, and first author of the paper, cites the numerous battery fire incidents in cell phones, laptops and electric cars highlighted in recent media coverage. The new aqueous zinc battery presented in this work could be the answer to the call for safe battery chemistry while still maintaining the comparable or even higher energy densities of conventional lithium-ion batteries. "Water-based batteries could be crucial to preventing fires in electronics, but their energy storage and capacity have been limited -- until now. For the first time, we have a battery that could compete with the lithium-ion batteries in energy density, but without the risk of explosion or fire," Wang said. This highly concentrated aqueous zinc battery also overcomes other disadvantages of conventional zinc batteries, such as the capacity to endure only limited recharging cycles, dendrite (tree-like structures of crystals) growth during usage and recharging, and sustained water consumption, resulting in the need to regularly replenishing the batteries' electrolyte with water. "Existing zinc batteries are safe and relatively inexpensive to produce, but they aren't perfect due to poor cycle life and low energy density. We overcome these challenges by using a water-in-salt electrolyte," says Chunsheng Wang, UMD professor of chemical and biomolecular engineering and corresponding author of the paper. The research team says this battery technology advance lays the groundwork for further research, and they are hopeful for possible future commercialization. "The significant discovery made in this work has touched the core problem of aqueous zinc batteries, and could impact other aqueous or non-aqueous multivalence cation chemistries that face similar challenges, such as magnesium and aluminum batteries", Xu said. "A much more difficult challenge is, of course, the reversibility of lithium metal,

Arkady Fiedler, the prominent Polish explorer, who in February, attempted
the first ever Electric Vehicle (EV) expedition across Africa, recently
berthed in Nigeria.
Using the first generation Nissan LEAF, the explorer began his trip in South
Africa, Cape Town, through West Africa.
A statement by the media consultant to the company said that the expedition
chosen vehicle ... Nissan LEAF ... powered by a 30kwh battery with a range
of 250 kilometres.
Travelling with Albert Wojtowcicz,a photographer, the vehicle had covered
over 8,000 kilometres, in a period of two months.
Addressing local media at the Stallion NMN showroom in Lagos, Fiedler said,
apart from being the first ever electric vehicle expedition across the
African continent, the trip aimed to build awareness of electric mobility
and new cleaner technologies in Africa, Poland and the world at large.
The voyage, according to him, also sought to change peoples’ perception of
the world and human choices with particular emphasis on the impact of
transport on the environment, Fiedler said.
He emphasized that the choice of the electric Nissan LEAF model was not by
impulse, but because of the quality of the brand.
“Caring for our environment, homes and families starts with us. This journey
is proof that something apparently impossible can be achieved with the
appropriate attitude and determination.
“When it came to considering which kind of electric car I would drive across
Africa, we took into account several brands, featuring similar
specifications, but this particular model was favoured. It has been a proven
model since 2010 and just in January 2018, the Nissan-Renault Alliance
announced the delivery of the 300,000th Nissan LEAF car sold worldwide.”
Besides being the world’s first 100 per cent electric, zero-emission car
designed for the mass market, its advanced powertrain provides a totally new
driving experience, with smooth, responsive acceleration with stable
handling and quietness. The first generation Nissan LEAF was named Green Car
of the Year in 2011.
Also reiterating that the initiative was conceived over time, Arkady said
the expedition was entirely his idea.
Fiedler however, decried the inadequacy of infrastructure such as charging
facilities in the course of the journey, which he said was the only
limitation to the attainment of a complete transition to EVs in Africa.
“While it is rather seamless to get electric sockets to fill the battery in
Europe, we have to rely on people to assist us in charging the car battery
without which the expedition wouldn’t have been successful,” Fiedler said.
Amit Sharma, Stallion NMN Head of sales and marketing, who received the duo
of Arkady and Albert in Lagos, said the company was proud to receive the
team.
He said the expedition was first of such with electric vehicle across the
continent.
Launched in December 2010 in Japan and the United States, the Nissan LEAF
first made its debut in Europe and other markets in 2011.
It has ever since continued to win numerous international accolades,
including the prestigious 2011 European Car of the Year, 2011 World Car of
the Year and 2011/12 Car-of- the-Year Japan awards among others.

An "unmanned" electric tricycle suddenly broke into a mobile phone retail
store in Taixing, Jiangsu Province, on April 22, Knews reported.
The tricycle stopped when it crashed into the store's counter. No one could
be seen behind the wheel, baffling witnesses, until the fluffy head of a
naughty dog appeared from the cabin.
The tricycle belonged to the fruit store next to the mobile phone shop,
where a staffer forgot to turn the vehicle off before heading inside.
That's when the naughty dog climbed into the tricycle to play, accidentally
stepping on the pedal and causing the vehicle to crash into the phone store.
Police are still investigating the incident.

[EVDL] DC-DC oddities continued
Well, just had the battery checked out, and it tests good for both cranking and voltage. This probably means that the little digital voltmeter I have hooked to the system is getter VERY confused. Combine this with the Tach Sensor no longer working reliably, and I do suspect a LOT more electrical noise than there used to be. Likely caused by my exploding contactor event - which ran an enormous current pulse through the Zilla motor loop. Zilla still works - but I'm wondering if some the input capacitors may have gotten damaged? I'm going to do some work so I can hook up one of my Fluke DVM's and be able to see the display while driving. Also switch it between AC and DC to help see how much noise there is on the line. -- Try my Sensible Email package! https://sourceforge.net/projects/sensibleemail/ ___ 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)

I worked on Gizmos many moons ago, and as I recall they had D&D 6.7" series motors, and Alltrax controllers. Many moons ago, I discovered a burned brush and guessed that it was due to low rpm, high current use by the previous owner. That is quite likely. The Gizmo was geared too low, so hill-climbing and demanding fast low-speed accelleration was hard on the brushes and controller. The guy that owned the Gizmos I worked on had a pile of burned-up motors and controllers. Adding a blower to cool the motor helped a lot. More recently, the Gizmo has been sitting idle. Perhaps someone can tell me why it feels as though it is cogging at low speed, even though it didn't use to do that. At higher speeds, the jitter and jumping goes away, but the low speed regime is from zero to about 20 mph and is painful to experience. I've been told from one of the Gizmo group denizens that when/if I fix the jitter, it would be wise to take a spin every two weeks or so to keep the jitters away. Would the commutator oxide over non-use and cause this problem? Because I retained the previous motor with the burned brush, I figured I'd get it checked out, repaired or rebuilt as required, but it's nigh impossible to find a motor repair facility in this area. One of the more recently recommended shops now has a sign that says something along the lines of "I'll be here if I feel like it. Call me to see if I'm here. If I'm not here and I feel like working, I'll call you back." He didn't call back. Through the shop window, I saw a sign that stated he does not work on electric vehicle motors, although I think I could have slipped the ES-10C by as something else. If the brush is all that burned, the commutator can be resurfaced and new brushes installed to resurrect the motor. This is not difficult work. I have the address in NY from which I ordered the current motor, but the shipping would be brutal. Where are you located? Are there any motor repair places listed in a city near you? Any place that works on golf carts, fork lifts, and industrial motors can rebuild your motor. Is it practical to expect to be able to dismantle the spare motor, replace the brushes and then what? If the commutator is straight and true (no bent or warped bars), you basically put the armature in a lathe, and take off just enough copper to clean up and smooth the surface again. Assemble the motor with new brushes and brush springs. Run the motor on the bench for several hours at low voltage to break it in. Do I need to examine and/or replace the bearings on which the shaft operates? Bearings generally last "forever". If they do need replacement, you need a press or gear puller. Again, that's not difficult to find. In summary (whew!), is the spare motor fixable by a handy tinkerer? I'd say it's worth a try. It's worthless if it's broken. How much worse can it be? ;-) Is the in-place motor problem something that is easily identified and as easily resolved? I can't tell. Maybe someone put the wrong motor and controller in it. -- I look for what needs to be done. After all, that's how the universe designs itself. -- R.

I have a Gizmo EV which uses a 10" Sepex motor. Many moons ago, I discovered a burned brush and guessed that it was due to low rpm, high current use by the previous owner. The motor was replaced with a rebuild version shipped from NY state to FL state at not insignificant expense. More recently, the Gizmo has been sitting idle. Perhaps someone can tell me why it feels as though it is cogging at low speed, even though it didn't use to do that.

I have the address in NY from which I ordered the current motor, but the shipping would be brutal. I like to think I'm handy, although physically falling apart as of late. After all, I was able to pull one motor and put in the other, but that was in healthier days. I can enlist some stronger hands for the hard stuff, should I solve the smaller problems. Is it practical to expect to be able to dismantle the spare motor, replace the brushes and then what? Do I need to examine and/or replace the bearings on which the shaft operates? Is there a task within the grasp of a mere mortal that must be performed on the commutator and/or windings? Of course, if all of the above is possible to accomplish by a tinkerer, that leaves the jittery motor in question. Once it is out, I'd like to have it operational without the jitter. The motor is in a position impossible to observe the brushes for sparking, as it has a ducted shroud at the brush location with forced air cooling. That, along with a lower gear ratio, should be providing improved air flow. This particular vehicle has a reputation for insufficient airflow. I had installed temperature sensors at the exit vents and discovered that in the heat of the summer, it stayed under 150°F, which I expect is well within safe limits.

[EVDL] Design News: "Build It and They Will Come" Doesn’t Apply to EVs
An OpEd The real culprit in the emissions debate continues to be consumer apathy. https://www.designnews.com/electronics-test/op-ed-build-it-and-they-will-come-doesn-t-apply-evs/99265535458645 - Op-Ed: "Build It and They Will Come" Doesn’t Apply to EVs The real culprit in the emissions debate continues to be consumer apathy. By: Charles Murray Electronics & Test Automotive April 27, 2018 The Trump Administration’s rollback of emission regulations may be the auto industry’s raging debate of the moment, but the economic forces underlying it are as old as the electric car itself. If, by now, electric vehicles were selling the way they were supposed to, Barack Obama’s 2009 mandate would look like pure genius. And Donald Trump wouldn’t need to talk rollbacks. You won’t hear that, of course, in any of the mountain of newspaper editorials urging automakers to ignore the EPA’s new direction (here and here and here). Most of the editorialists contend that the automakers want the regulations. And they quote them as saying so. “We continue to support increasing car standards through 2025 and we have not asked for a rollback,” Ford Motor Co. is quoted as saying in numerous articles. “Regardless of the standards, we remain committed to improving fuel economy, reducing emissions, and an all-electric future,” General Motors says. Strange, then, that the Alliance of Automobile Manufacturers, which represents Ford, General Motors, Toyota, Volkswagen, and eight more of the world’s biggest automakers, takes such a contrary stance. On the day of the EPA’s announcement, the Alliance called it “the right decision.” “We appreciate that the Administration is working to find a way to both increase fuel economy standards and keep new vehicles affordable to more Americans,” the Alliance wrote in a press release. To know what automakers are really thinking, it’s best to examine some of the federal documentation. In the Mid-Term Evaluation Final Determination, commenters referred to “flagging consumer demand” for electric vehicles. The group Global Automakers—which includes such members as Honda, Nissan, Kia, Hyundai, and Toyota—referred to a “misalignment between the increasing stringency of the standards and the decreasing demand for fuel efficiency.” The looming 54.5 mpg goal The crux of the argument lies in the estimates of what it will take to reach the 54.5 mpg target. Under the Obama Administration, government regulators estimated that manufacturers could hit the 2025 targets with fleets that included 3% hybrids and 4% plug-ins. Automakers argued they would need about five times that many. Even Nissan, which bravely rolled out the Leaf EV in 2011, has challenged the government numbers. In a comment, Nissan wrote, “Higher penetration of advanced technology vehicles than originally estimated by EPA and NHTSA is needed to achieve GHG (greenhouse gas) and CAFE (corporate average fuel economy) goals.” The thought of building 35% electric strikes terror in the hearts of automakers—especially now. In 2017, approximately 1% of the vehicles sold in the US were plug-ins. About half of those were pure electric. Building a high percentage of electrics and then having them sit unsold is, understandably, a nightmare for manufacturers. GM plans to roll out 20 new electric vehicles by 2023. (Image source: General Motors) None of this, of course, is taken into account when editorialists weigh in. Absent from the newspaper discussions is any mention of cost-benefit analysis. How, for example, does a 54.5-mpg mandate differ from, say, a 40-mpg mandate in tons of atmospheric CO2 emitted? Does 54.5 differ from 40-mpg in the effect on vehicle cost for the average consumer? Or from 45 mpg? We’re not told that. In truth, most such editorial conclusions are reached on the basis of a simple premise: Gasoline, dirty; electricity, clean. By logical extension then, any and all proposals would seem eligible to solve the problem—75 mpg, 100 mpg, or even a sweeping all-electric mandate. But what automakers really want right now is help from the government in selling electrified cars. They like the $7,500 federal tax credit. And they like state support. As Nissan writes, “Continued governmental efforts to expand the EV market are, thus, essential to complement the efforts already in place by EV industry leaders such as Nissan.” What they don’t want is a mandate to mass produce cars that consumers still find too costly. And, yes, cost matters hugely in this discussion. A case in point: A recent Chicago Tribune review praised the Tesla Model 3, while acknowledging that it cost $51,500, as tested. Fair enough. But would the average American (household income of $59,000 a year) choose that Model 3 over a Honda Accord, Toyota Camry, or Chevy Malibu that cost $25,000? Even if you removed the frills, applied the tax credit, and changed the differential to $7,000, would they
