Re: [EVDL] Nikola Motor sues Tesla over design patent violation
Sounds like "and if you can't win, sue them." I put the pics of the two trucks next to each other and can't see much similarities other than that they both have wheels, sweeping windshields and streamlined face, but just about every new designed vehicle rendering has the same. -Original Message- From: EV [mailto:ev-boun...@lists.evdl.org] On Behalf Of Marco Gaxiola via EV Sent: Wednesday, May 02, 2018 7:12 PM To: Electric Vehicle Discussion List Cc: Marco Gaxiola Subject: [EVDL] Nikola Motor sues Tesla over design patent violation https://www.electrive.com/2018/05/02/nikola-motor-sues-tesla-over-alleged-design-patent-violation/ Nikola Motor has filed a lawsuit against Tesla claiming the Semi electric truck to be “substantially” similar to Nikola Motor’s own design of a fuel cell electric semi truck.

I can't speak to their infringment claims, but I will say that I wish I had $100 for every EV startup in the last 40 years that talked up big glitzy plans to build an expensive factory in some out of the way place. I've seen it happen over and over again, largely thanks to Bruce's diligent pursuit of these stories. Here's the way it usually goes. The company gets a bargain-priced option on a chunk of land. They make glowing promises of skilled high-wage jobs Real Soon Now. The state and county governments offer them tax abatements, and sometimes even build expensive taxpayer-financed infrastructure for them. The target date for groundbreaking comes, but ... oops, there's a little hitch. The financing isn't all lined up, or something. Whatever. The date gets pushed out a few months, then a year, then two, then three. The land the company optioned sits empty. More years go by. The slick website hasn't been updated and they've long since quit posting on social media. Nobody answers the phone. The newspaper sends a reporter to knock on their office door, but it's silent, abandoned, dark and dusty. The reporter writes a "whatever happened to" story anyway. And then it's all forgotten, even the incentives paid for by taxpayers, and the city and county and state move on to some other entrepreneur's vague promise to spend his investors' money hiring a few locals. Will these guys be an exception? I hope so. We could use more competition in the EV business. I'm not thrilled with the fuel cell idea, I don't have much respect for companies whose main product is lawsuits, and the name "Nikola" strikes me as a dumb idea. But I wish them success in building and sellng EVs.

Note: when public EVSE is installed in his area, those EVSE may not work
with his zivan charger. Zivan chargers do not have a high power factor
correction (like a PFC-40), thus can have AC current spikes which some
public EVSE detect and shut off (the charge will begin OK, but after several
minutes and you have walked away, the EVSE turns off the supply of AC power
to the Zivan= frustrating). %

% Hazem's Sartell-MN neighbor Lee Hart might know of a MN person that could help with any future EV repairs/issues. Changing a pack is a good opportunity for modifications/additions. Like adding battery plate warmers and or pack insulation. https://www.google.com/search?q=car+battery+heater https://www.google.com/search?q=auto+battery+heater According to Lee's (dated) post: https://www.mail-archive.com/ev@lists.evdl.org/msg19192.html battery heating pads Lee Hart via EV Tue, 03 Jan 2017 He likes using an electric blanket keep his pack warm. Which would mean two $30 120VAC blankets for both front & rear packs: https://www.google.com/search?q=electric+blanket=shop=p_ord:p I'll assume Hazem hasn't changed a pack before. This 1st time pack change will take at least two days (do not be in a hurry, do it right), so be sure to have alternate transport (go to work, run to the store, etc.). It is important to do your prepitory homework ahead of time. On paper, map out both the front and rear battery packs, noting the battery orientation + & - terminal positions), and map the battery cable routing. I also like to number each cable: after each cables removal and cleaning, I use a permanent marker to label each one so they go back to the same position, Cleaning the cables and the racks they sit in is important. You not only can note/document wear-n-tear, but also the cleaning neutralizes acid buildup/corrosion. The 1st time I changed my Solar Electric conversion (my former S10 Blazer http://brucedp.tripod.com/blazer/ ) I did the above: documentation, used a windex-type glass cleaner & paper wipes, a bottle of rubbing/isopropyl alcohol, and had a voltmeter by-the-ready. You should have a voltmeter. Walmart has them for ~$10 https://www.walmart.com/ip/Neiko-40508-830B-Digital-Multimeter-AC-DC-Resistance-Current/197985834 This also a good time to check the health of the 12V auxiliary battery (if it is 9yrsold, then its time to replace it too https://www.solar-electric.com/repoba12vo95.html ), and verify the voltage output of the DC to DC & 12V charger are set correctly. In the past I thought setting the 12V charge voltage to finish at 14.4V was correct. Since then, I have found 13.8 to 14V is best for me (it seems to be more gentle on the 12V deep-cycle aux battery). After recording your finishing pack and aux battery voltages, disconnect the chargers from the AC power, and turn/pull the red emergency switch to off. Use the mild-alkaline glass cleaner to clean the surfaces of the batteries before removal (I used a ~$10 battery lifter strap the battery source supplied http://www.ezred.com/wp-content/uploads/2013/10/BK560.jpg - do not use the lifter type that lifts using the posts= very bad https://d26maze4pb6to3.cloudfront.net/8413/6363/7683/CarryStrap.jpg https://www.google.com/search?q=car+battery+lifter+strap ), and later use the glass cleaner as a first pass to clean the cables (the cables will need a second cleaning using the alcohol to remove the glass cleaner residue). After the batteries are removed, use the glass cleaner to clean the racks before the new batteries go in. If you find corrosion, then those areas will need a cleaning/scrubbing using a baking soda +water solution to neutralize that area, then several passes of water rinsing, and then the glass cleaner to remove the dried baking soda powder residue. Battery cable's terminals (I assume yours are the automotive post type https://www.zoro.com/quickcable-straight-terminal-20-ga-orange-pos-4020-525-001p/i/G7499782/ should be cleaned with alcohol, and checked for corrosion both on the terminal/lug and lug-bolt/nut, but also for any corrosion that has creeped up into the cable's crimped lug end. After several years of pack changes, the cables solar-electric made were tired, and I had to learn how to make new ones by cutting 00 cable to length, striping back & putting noalox on the ends https://www.google.com/search?q=noalox and then using a crimping tool putting new terminal/lugs on. Hazem may not need to replace his cables at this time, but he should clean the ends well. After the pack has been replaced, and after a couple of weeks of driving & the terminal/lug bolt tightness re-checked (driving vibration loosens them) ... at the very end of all of that, then you apply an anti-corrosion grease coating on outside metal terminal/lug surfaces (do not use the cheapie spray on type, it does not last) https://www.google.com/search?q=battery+corrosion+grease+coating Charging @work If I did my web search correct, Hazem has two locations he visits/works at.

[EVDL] Design News: Power Out Of Thin Air: Wireless Charging of Elecrtic Buses Proves Its Worth
https://www.designnews.com/electronics-test/power-out-thin-air/153947192358622 - Power Out Of Thin Air Wireless charging of electric buses proves its worth By: Kevin Clemens Electronics & TestBattery/Energy Storage, Sustainability, Automotive, Automotive and Mobility May 01, 2018 One of the ongoing debates about the general acceptance of electric vehicles (EVs) is the need for wireless charging. Proponents of such systems point to the ability to park over a pad embedded in a parking spot and pick up 20-30 miles of range while grocery shopping. They say that this so-called "opportunity charging" helps to reduce range anxiety, making EVs more attractive. If you put the same charging pad in your garage, you simply park over it at night and the car automatically adds the electricity needed for the next day’s commute. The convenience of wireless charging comes with a price tag, however. Wireless charging adds a need for costly equipment both in the home garage and onboard an already expensive electric vehicle. Current owners of EVs find that remembering to plug in their charger at night is a small price to pay for never having to stop at a gas station. They always have a full “tank” in the morning. Wireless charging an EV works in a similar way to wirelessly charging a cell phone. Electricity is transferred from the coil in the charger on the ground to a coil located on the bottom of the vehicle through induction. It is important that the coils are parallel and closely aligned to one another. The air gap between the coils is also critical (4-6 inches is typical). If everything lines up properly, charging efficiencies for inductive charging can be as high as 85-90 percent. One application where wireless charging can show real advantages is with heavy vehicles—and most particularly city buses. A Pennsylvania company, Momentum Dynamics, has just announced the commissioning of a 200-kilowatt wireless charging system for a bus fleet in Wenatchee, Washington. The system is operational on a BYD K95 electric bus operated by Link Transit. The 200-kilowatt charger adds enough energy to the bus battery during a five minute stop to allow it to complete another route cycle. The charging system is embedded into the pavement at a Link Transit transfer station stop. Each time the BYD bus parks over the charger, its battery is automatically recharged. “The simplicity along with the seamless charging allows Link Transit to operate all of our urban service routes continuously without the need for midday charging,” said Todd Daniel, Technology Manager for Link in a press release. “Link is planning to expand this technology for our longer rural routes in the near future, which will assist in the agency’s goal of 100% fleet electrification,” he added. The technology involved has proven to be quite adaptable. “On this BYD bus, the distance between the charging coil mounted flush with the cement and the vehicle coil is approximately 7 inches,” Ben Cohen, vice president of engineering for Momentum, told Design News. That distance is typical for low-floor municipal buses, but can vary up to a distance of 12 inches on other types of vehicles. Cohen reported that the overall charging efficiency is 92%. Almost all of those losses were from the power electronics—virtually no losses were coming from the wireless power transfer. The cost of the Momentum Dynamics wireless equipment is similar to the cost of equipment on the vehicle used for fast DC charging. Cohen told Design News that those costs are dramatically affected by product volume. The company is also working on a larger 300-kilowatt wireless charger that should be available in 2019. By next year, Momentum also plans to have rolled out wireless charging to several other bus lines in the US and Europe. Senior Editor Kevin Clemens has been writing about energy, automotive, and transportation topics for more than 30 years. He has masters degrees in Materials Engineering and Environmental Education and a doctorate degree in Mechanical Engineering, specializing in aerodynamics. He has set several world land speed records on electric motorcycles that he built in his workshop. - Len Moskowitz ___ 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)
