Re: [EVDL] Lithium Battery Testing
I have the ev power moduals also . just HV/ LV make it hard to know whats going on . I'd use water heater elements or dryer elements for the draining/ testing . then use the volt meter when the LV comes and watch the red/green lights . my 24 cell scooter has gbs cells, so I got "cell log 8 s" with the logging and can ride download. I can also set it to alarm at semi LV . all gets down to time n money . ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
Re: [EVDL] hub motor for 20" wheels
Just realized you're looking for a 36V solution and the Currie setup is for 24V. Go to http://evdeals.com/Currie%20Kit.htm and see their similar kit and options. Theirs is 24V too, but call Scott at 508-695-3717. I'm guessing some of his motor options could be run at 36V just fine, and you'll need to overspeed it anyway to get that tiny 20" rear wheel up to 20-25 mph. It's a good bet that Scott will know if that's feasible. The main advantages with this approach are that you keep your original wheel and there's less weight added to it. Not a small concern for a bike with a suspended rear wheel. Understand if you do this it will ride harsher just because of the added weight on the wheel.

Re: [EVDL] Breakers in Reverse?
Yes, there are control circuits on the load terminals. The line side is connected directly to the line contact of the internal switch. The load contact has a overload circuit that connects to a overload relay similar to the overload relays that are use in magnetic starter. In some circuit breaker, the load side terminals may be connected to other optional circuits for shunt control, remote control of the breaker and operational indicator of the breaker. We wire the positive and negative to the breaker from the power source or line side and the output to the loads on the load terminal. Be sure to use a circuit breaker rated for DC. Some breakers are rated for AC and DC.

Cor van de Water via EV wrote: I believe that Lee responded to a similar question a while back that there are some breakers, where a circuit is connected to the load side of the breaker so if it trips then it is no longer powered but put it in reverse and it remains powered and might overload. I forget what type of circuit was on the load side of those breakers, it might be a coil. Yes; a GFCI breaker is a common example. The GFCI circuitry is powered from the load side of the breaker, so it is automatically switched off when the breaker trips. Some breakers have "trip" coils that get energized to force it to rapidly trip when some threshold current, rate-of-rise in current, arc detection, or other event occurs. These circuits are likewise powered from the load side, so they get turned off automatically when the breaker trips. The other reason that polarity can matter on a DC breaker is that there can be arc-suppression components that depend on knowing the polarity. For instance, blow-out magnets that push the arc in a "safe" direction when the current flows from line to load. If the current flow is backwards, the arc gets pushed the "wrong" way, where it can damage other parts inside the breaker. As an example, I have a Heinemann 160vdc breaker. It has a screened arc port, and you can clearly see the blowout magnets on each side of the contact. When it opens a current from line to load, the magnets blow the arc OUT the screened port. If it opened with a current from load to line, the arc would be blown INTO the guts of the breaker, where they could do a lot of damage. You really have to contact the manufacturer of the breaker and ask THEM for a definitive answer on the particular make/model you are using. -- A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away. -- Antoine de Saint Exupery -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

Re: [EVDL] Which one china lifepo4 60 Ah?
Why NMC/LMO/LCO over LFP on OEM EVs? Due the cell cost. LFP base patents are still valid for few years while others are free game. Sometimes I feel they also wanted to make shitty solutions to prove EVs are no-go. You just got to love how Tesla is wiping floor with those arrogant a*#%¥£es. :) When comparing Chinese LFP providers it's good to remember the original developer of this tech. Nearly all prismatic cell manufacturers are originally TS license factories. TS provided tech to all of them. Then many of the factories (couple dozen) have taken their own path. Many of them have not continued to buy raw materials from TS and have started their own development. Many buy LFP from other vendors who build very different LFP. Cells may perform better and give more power but we are after calendar life. We've proven 10 years on the road on customer cars (with super good BMS made by yours truly and MetricMind Victor). Also TS has mastered the water based slurrying over a decade and only now others have started to adopt it. The GigaFactory solvent recuperation process is another way to find cost efficiency but it takes space and requires more investment. TS water slurry coaters fit 8x more production capacity in the same space and no VOC! There is also now a major change coming to the production process which may (if successful) 30-fold the producion speed. TS aims to have the best cost efficiency so there is no excuse for anyone not to go for EVs. The inventor of TS is an EV geek just like us. Also very nice and warm hearted person. He always tries to do the best to serve us but due the good will too many exploit it and there is just so much one man can do. It's not his or his products fault if cells go smokey with no BMS. We have been looking vast amount of solutions how to integrate BMS to the cell and there are now few very good options we will test extensively out. It would also be benefical to have formation data on the chip so it's easier to see how the rest of the formation is completed after installation. Yes. It takes several hundred cycles to 'build' so it matters quite alot how you use cells when you pull them out from the box. Other manufacturers cycle more and age the cell longer. TS let's you decide how you do it. Your BMS will in most cases do it for you. Never go without BMS. Also never use s€&@t for BMS either. Use good and well tested ones. If you have still working TS cells in the pack replace the broken ones with new similar cells and add good BMS.

[EVDL] EVLN: EVTripping.com app enhances an EV road trip experience
[ref http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-EVTripping-com-app-enhances-a-Tesla-road-trip-experience-td4683301.html ] http://www.teslarati.com/evtripping-app-tesla-roadtrip-planning/# ‘EVTripping’ launches app to enhance the Tesla road trip planning experience August 9, 2016 Rob M. Planning a road trip with the Model S and Model X is as easy as plugging in a destination address through the vehicle’s onboard Nav, getting in the car, and then going. At least that’s what Tesla’s Trip Planner aims to do, but the truth of the matter is, it falls short on some areas that I find critical when planning for a long distance all electric road trip. Having gone through a busy summer of traveling, with one Tesla road trip taking me as far as Boston to South Florida, and another trip to Alaska – though this one I flew to, I’ve had time to think about additional features that I myself would like to have access to when planning for an EV trip. I figured that if these are features I felt a need for, there certainly has to be other folks within the Tesla community sharing the same sentiment. So I decided to build it. EVTripping.com North to Alaska! Picture of Denali, the highest mountain peak in North America EXISTING EV PLANNING TOOLS Let’s start by highlighting some of the popular services out there: PlugShare, Teslarati’s Interactice Supercharger Map, OpenChargeMap, and the popular EVTripPlanner. Each service has its own specific purpose, and they all provide a wealth of information for trip planning. But still I wished I can somehow combine features from each service into one app, but also add to it with additional features. I’ve compiled a wish list of features that I hope to address with EVTripping. At present time no app or service that I know of, outside of the existing Tesla navigation system, is able to predict charge times needed for charging stops. Tesla does it but they tend to be overly optimistic about how much charge time is needed. (EVTripPlanner has since added more realistic charge times which is very helpful) We need to be able to see true elapsed time for the trip in order to better predict where one will be at any given time It would be nice to be able to see points of interest along the journey such as destinations for food. Being able to export the trip planning details in digital form or print it out as a PDF would be a nice to have. Weather is a variable that can change along your journey. This should be reflected when planning for a Tesla road trip. CREATION OF EVTRIPPING I’m proud to announce that less than 6 months after I conceived the idea for a new online trip planner EVTripping.com was born. If you want to learn more about the sequence of events that led to the launch of EVTripping.com, follow along and check out the timeline which describes everything that’s being worked on. Response to the site has been overwhelmingly positive despite very limited coverage so far. We’ve added over 200 registered users in less than a week and routed almost a quarter million miles on the production site. I’ll speak of the site in terms of “we” and “our” because, while I’m the chief cook and bottle washer for the site, I see this as a project for and by the community. Many of you are already helping by filing bug reports, suggesting feature requests and sharing ideas. We’ve been busy this first week of launch. We’ve fixed buds, added international support, adjusted time based on a user’s geography, built multi-language support, added foreign character support, and continue to refine the routing intelligence. Early users of the app have been super helpful and supportive so I’d like to thank each and every one of them. FREE TESLA MONITORING I’ve written an open-source tool before that allows me to take control of my Tesla while also monitoring my SolarCity production. EVTripping adds much of the same functionality when it comes to notifications. The app will monitor your Tesla and remind you when it’s time to rotate your tires, how much you’re driving, the efficiency you’re getting, and more. Not plugged in I’m focussed on building the tools I need for my Tesla lifestyle and will share them with the community along the way. THE FUTURE We’re not done yet with EVTripping. I call this stage the “minimum viable product”. Where we go from here will depend on you and others within the EV community. Though I have plenty of product level ideas, we can decide on these together. One of my big dreams for the site is to add support for other EVs beyond Tesla. I’m defining an EV as an electric vehicle capable of taking a road trip using Superchargers, CHAdeMO, CCS, etc, versus one that you can take trips in, but have to plug in for many hours each time you stop. There’s no shortage of media outlets covering Tesla, and fantastic podcasts like Ride the Lightning and Talking Tesla, but my focus since I began writing was to talk about the lifestyle component of owning, and
[EVDL] If you build it, will they charge? Utilities' cautious plans to spur electric vehicle adoption
% Utilities' deep-pockets are actually rate-payer funded, the utility people making these decisions do not drive Electric, nor do they involve EV drivers in the decision process. There is nothing more wasteful than an EVSE installed in a location drivers do not want to go, or its use-fee too high so they do not use it. EVSE installations should be designed to be dynamic: to be able to shift/relocated-to where it is needed. % http://www.utilitydive.com/news/if-you-build-it-will-they-charge-utilities-cautious-in-plans-to-spur-elec/423982/ If you build it, will they charge?

Avista Utilities will spend $3 million to install, own, and operate 272 grid-integrated electric vehicle (EV) chargers at about 200 residential, workplace, and public charging sites in its Eastern Washington state service territory. The utility's intent is to understand and prepare for managing the impacts of a higher EV charging load on its system. The state of Washington had over 16,000 EVs at the end of 2015 and the Washington State Electric Vehicle Action Plan targets 50,000 plug-in vehicles by 2020, according to Avista Utilities Manager of Electric Transportation Rendall Farley. The state currently has 1,544 public charging outlets, and it doesn’t take a mathematician to divide 50,000 by 1,544 and get chaos. That is an exaggeration of the imbalance, of course, because the number of chargers will grow with the adoption of EVs. But it is emblematic of a potential national imbalance between cars with plugs and spots to charge. The U.S. has 482,217 EVs, according to Plug-in America, and there are 14,040 public charging stations and 35,006 charging outlets, according to the U.S. Department of Energy. Considering a level 2 charger’s 10 to 20 miles of range per hour of charging rate, 35,000 chargers for more than 482,200 cars is not a formula for convenience. And, while small pilots like Avista’s are emerging, the imbalance may be growing. “Largely funded by DOE and state programs, there was a significant EV infrastructure build-up between 2011 and 2014, GTM Research Senior Analyst Ravi Manghani told Utility Dive, "but in recent months EV sales have outstripped infrastructure growth." To address the imbalance, the White House just announced a plan to make up to $4.5 billion in loan guarantees available to accelerate EV growth. A key goal of the plan is to stimulate public-private-utility partnerships that will drive more deployment of charging infrastructure. The Department of Energy also has a strategic partnership with the Edison Electric Institute, the trade group for investor-owned utilities, to expand EV adoption. Despite that, many utilities say they face the problem of whether to build out EV charging infrastructure now, betting on later adoption, or to wait for consumer demand to pick up, and risk slowing EV growth and being froze out of the charging market. Though the Avista pilot's numbers are small, its structure may point the way toward some larger strategies to solve the national EV imbalance. DC Fast Charging stations can be too expensive for private vendors to install at public locations, opening an opportunity to deploy utility capital. The utility charger scene Utilities would seem to have the deep pockets to support large charger infrastructure builds and they could benefit from the increased load, but they have been hampered by regulatory constraints. “This is a tricky market for utilities,” said GTM Research Analyst Timotej Gavrilovic. In California, which leads the country in EV adoption, regulators scaled back Southern California Edison’s $22 million Charge Ready pilot and San Diego Gas and Electric’s $45 million Power Your Drive program in final approvals. Pacific Gas and Electric proposed the most ambitious U.S. utility charger installation program, has twice had it scaled back by regulators, and is still awaiting a final ruling. The Los Angeles Department of Water and Power faces a mandate requiring electrification of 80% the city’s fleet vehicles by 2025. At present, it is focusing on its own fleet, providing technical and other kinds of support for other City Departments, and “exploring new technologies,” according to Spokesperson Amanda
Re: [EVDL] Breakers in Reverse?
I believe that Lee responded to a similar question a while back that there are some breakers, where a circuit is connected to the load side of the breaker so if it trips then it is no longer powered but put it in reverse and it remains powered and might overload. I forget what type of circuit was on the load side of those breakers, it might be a coil.
