Re: [EVDL] 18650 cell level fuse wire
The open air fuses of Tesla packs eliminate the sort of creepage failure that Justin has recounted.where aerosol deposits from the vaporizing of the fuse leave traces for further arcing and leakage.

First hydrogen is not a zero emissions fuel so I'm calling it as I see it.

Still better with but if you charge from two J1772 and have big charging amps with a small pack it can be done. To add to that it's a good emergency charging solution.

Re: [EVDL] Using EV to demo emergency power
Just to be clear, you were doing only 120vac? That is, half the outlets in the building were dead? He turned off and tagged out the circuit breaker, not the panel breaker, so ONLY the lights and outlets on that particular circuit were energized by the inverter. (All other circuits were powered by the grid.) I agree that a simple "tag out" without some type of physical lock/interlock isn't something you want to do long term, but as he was on-site and presumably monitoring the circuit/system/panel it doesn't seem too dangerous. (Unless he used a suicide cable that somebody could unplug from the outlet and touch the ends while it was still powered by the inverterI was also concerned when he said he had moved the outlet circuit to the same breaker as the light circuit, which made me suspect he had a double-tap off of that breaker, which is also a No-No.) Jay ___ 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] Curtis 1231C value
I've seen them on Ebay in the 800$ range so that price doesn't seem unreasonable (but that might just be yours.) If I needed a controller NOW to replace the one in my truck, I might pay $800, but would feel better about the 600-700 range. (But then again, I might spend $1300 to upgrade to a more powerful controller that wouldn't die like the last Curtis ;>) This is the one I have currently have my eye on if I need a replacement: https://www.evwest.com/catalog/product_info.php?cPath=1_id=451 http://www.zeva.com.au/index.php?product=120 The main value to the Curtis that it is a drop in / bolt on replacement for the unit that I currently have, so I wouldn't have to add a water cooling loop, etc..the down side is that they are old technology, and modern controllers are more robust and offer better power and more configuration options in the same sized package. To buy a hot spare just to keep on hand I would pay $250-350 now. So I guess it depends upon if you are waiting for a motivated buyer, or if you want to sell it within 30 days.

Most fuses *are* a piece of wire of adequate size. :-) The trick is in the choice of wire, and in how it is packaged. The choice of wire is important. Normal wire sizes aren't that precise; the variation in cross-sectional area is around %5. Then, due to high high metal prices, vendors tend to "cheat" (since they know consumers won't measure it). It's not uncommon to find cheap wire that is 2 or 3 sizes smaller than the package claims. The purity of the metal is also important. Copper is not a good choice. Tiny amounts of impurities in copper cause a huge change in its resistance. Copper also work-hardens; its resistance increases as a result of flexing. When held near its melting point for long periods (like a fuse that doesn't quite blow), it crystalizes and develops stress cracks that significantly alter its resistance. Silver is a better choice for fuse wire. The packaging is important. Just like food, if you don't package it correctly, it will go bad before you can use it. A wire in open air is subject to being cooled by moving air, heated by surrounding parts, corroded so its diameter shrinks, and even mechanically stressed if its ends can move (like a wire between cells that move as they expand and contract). The ends of the wire matter as well; they can act as a "heat sink" to pull heat away from the center, so it takes more current to melt it. So proper fuses are packaged to create a controlled environment around it. -- The belief that there is only one truth, and that oneself is in possession of it, is the root of all evil in the world.

[EVDL] Utility encouraging WiFi-connected EVSE 2control grid-load
https://www.austinmonitor.com/stories/2019/01/austin-energy-tries-to-encourage-austinites-to-buy-electric-cars/ Austin Energy tries to encourage Austinites to buy electric cars January 18, 2019 Jack Craver [image / austinenergy.com https://www.austinmonitor.com/wp-content/uploads/2018/10/Austin-Energy-Electric-Drive-1.jpg (Bolt EV @L3 EVSE) ] Last week, the city of Austin was awarded a coveted $2.5 million grant from a foundation funded by former New York Mayor Michael Bloomberg to pursue a number of environmental initiatives focused on energy efficiency and green transportation. While the Transportation Department will be using part of the grant to zero in on getting people out of their cars, Austin Energy is leading an effort to get the vast majority of Austinites who do drive to opt for electric vehicles. At a Monday meeting of the Electric Utility Commission, Austin Energy staff and members of the commission discussed the challenge of getting drivers to go electric. One of the big problems: car dealerships. “Salesmen don’t like to sell these things because they don’t make any money and the dealer doesn’t either,” explained Commissioner Michael Osborne, who is also chair of the board of the Texas Electric Transportation Resources Alliance, an advocacy group. The problem, said Osborne, is that electric vehicles don’t require nearly as much maintenance and rarely need major repairs. Since dealerships make much of their money servicing the vehicles they’ve sold, they’re not as motivated to sell electric cars. Thus, dealers tend to offer their sales reps less generous commissions for electric vehicles. There are roughly 6,800 electric vehicles in Austin. That puts the city above average, said Karl Popham, manager of electric vehicles and emerging technologies for Austin Energy. The electric car market nevertheless remains decidedly niche, mostly occupied by those who are passionate enough about the technology to seek out an electric vehicle on their own. Rarely, however, does a consumer go to a car lot to browse and end up leaving with a new electric vehicle. Popham said he has heard “horrendous” stories from people trying to buy electric cars. They often receive inaccurate information about the mileage that the cars can get per charge or the federal and state tax credits available for electric vehicle purchases. Over the next two years, Popham’s team will reach out to dealerships to provide education on the vehicles in hopes of boosting electric vehicle sales. “With the right educational tools and messaging in place, we commit to complete training and outreach to 100 percent of regional car dealerships that show strong demand for electric vehicles by December 2020,” said the work plan that the city submitted for the Bloomberg grant. “With assistance from the Climate Challenge and enhanced dealership education for electric vehicles, we think the Austin region will have over 10,000 electric vehicles on the road by 2020.” This new effort supplements existing initiatives that Austin Energy has put in place to facilitate EV adoption. The utility already has more than 650 charging stations around its service area. Drivers get unlimited access for only $4.17 a month. While many EV owners plug their cars into ordinary electric outlets in their garages, AE offers rebates that cover 50 percent of the cost of purchasing and installing a 240 volt charging station, which charges the cars faster. The maximum rebate for a normal station is $900, but the utility offers an even bigger rebate ($1,200) for Wi-Fi-connected stations. The goal with connected charging stations, explained Debbie Kimberly, who is in charge of the utility’s energy efficiency programs, is to allow AE to reduce the charge during peak demand (usually between 4 and 6 p.m.). Thousands of AE customers are already enrolled in a similar program that allows the utility to adjust their thermostats to reduce energy consumption during peak demand. The grant does not provide the city cash but rather $2.5 million “in a technical support package that may include things like a full-time adviser to work on the development and implementation of our projects, outreach support, data analysis and technical support, stakeholder engagement strategy and facilitation,” explained Amy Petri, a spokesperson for the city’s Office of Sustainability.
