>The real proposition is in the city - where you dare not leave anything that >the punks down the street can steal.< ] And people thought I was over cautious. Actually it is wise for drivers to be careful to not give an opportunity for someone to disable their plugin from charging. The last thing a driver needs is to come back and find their L1 EVSE has been stolen, or their cord swiped, or to come into an EV spot to find the EVSE has been attacked by vandals. In my early-early days of pushing the envelope, before there was such a huge amount of public EVSE to tap into, I would find outlets, & the older-generation EVSE damaged. I would have to plan to have enough range left in my pack when I arrived at a known charging site to still make it to the alternate site if I found it damaged. How often did this happen? Often enough to be a driver hardship: show up and the EVSE is down because of malicious human behavior. A long time ago, there were two AVCON EVSE installed behind a Walmart in the northern Sacramento area. The site was so convenient, that I planed to use it again on the following 320+ mile trip from Silicon Valley to Sacramento and back. But on the following trip, I found the AVCON EVSE had been attacked (it looked like kids took a metal bat to it). One of the couplers was busted wide open, and the other was damaged. I was able to trick the later into giving me a charge, but I avoided that site in the future as no one was fixing these EVSE (those were pre- Fed Gov. funding of public EVSE). Here is a pic of a TAL 2000 with a broken spi handle: http://www.recargo.com/system/site_photos/1491/big/userUpload.jpg http://www.evchargernews.com/photos/93023_2b.jpg The design of the TAL has the paddle out front where any big van or truck can come into the space and purposely bash into it. Here is a J1772 coupler that has been busted up: http://www.plugincars.com/why-baltimores-vandalized-charging-stations-have-taken-too-long-fix-127614.html http://www.plugincars.com/sites/default/files/WaterStChargePoint02%20copy.jpg Recently after the BBC TopGear fiasco of them purposely try to deceivingly show the Tesla did not have the range, another TG episode mentioned: http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-BBC-s-TG-Won-t-10-year-old-boys-just-go-around-unplugging-EVs-td4364660.html “I was wondering,” May mused, “when, in the future when we’re all driving electric cars, as they all tell us we will, the cities are full of these charging points, won’t 10-year-old boys just go around unplugging cars, because that’s what we would have done when I was 10.” I have had this happen to me. Which had me learn to make it a habit to go back and check on my charge every half hour to ensure my cord(s) were still in place and my S10 Blazer EV still charging. This repeated effort seemed a bit nuts to everyone else, but its what you had to do when you really-really need a charge when out in the middle of nowhere. So, its a fact that humans do bad things, and so bad things are going to happen to our beloved public EVSE. But is the inductive EVSE really 'that' vandal proof? The original newswire in the thread (above) as about Nissan's inductive efforts, see: http://www.nissan-global.com/EN/TECHNOLOGY/OVERVIEW/wcs.html http://www.nissan-global.com/EN/TECHNOLOGY/OVERVIEW/charging.html http://www.nissan-global.com/JP/TECHNOLOGY/FILES/2010/07/f4c4d5aceaf480.jpg http://www.popularmechanics.com/cars/alternative-fuel/electric/2014-infiniti-ev-to-debut-wireless-inductive-charging-system http://www.popularmechanics.com/cm/popularmechanics/images/wp/Inductive-Charging-1111-mdn.jpg And the poster referenced to: http://qualcommhalo.com/index.php/technology.html?id=36#technology http://qualcommhalo.com/images/articles/technology-architecture-1.png There is also the following to know about: http://inhabitat.com/evatran-now-accepting-pre-orders-for-plugless-power-wireless-ev-charging-system/ http://assets.inhabitat.com/wp-content/blogs.dir/1/files/2011/12/plugless-power-4-537x365.jpg The whole idea of having an EVSE that does not need a human to connect it (other than to drive the vehicle into the space correctly, and that make be automatically taken care of in the future with robotic-self-driving plugins) seems more vandal-proof. OK it all seems straight forward, but what if a local yayhoo takes a ran-over-flattened can http://image.shutterstock.com/display_pic_with_logo/1325/1325,1206898877,3/stock-photo-flattened-and-cubed-metal-and-aluminum-cans-awaiting-transport-to-the-recycling-plant-image-can-be-10928440.jpg and sticks it to the top surface with their chewing gum? The metal would disrupt, stop, or slow the magnetic transfer of power to the plugin, right? How much of a difference would there be if the can were aluminum or steel/bi-metal? Would the entire surface have to be covered to have an impact? Looking at the Nissan inductive unit on the ground (above URLs), wiring that is feeding the unit is exposed. Vandals could easily damage those. To be a good selling point, inductive EVSE should to be designed to deter vandals. Anyone have any views on this? {brucedp.150m.com} ... http://www.urbandictionary.com/define.php?term=yayhoo -- http://www.fastmail.fm - A no graphics, no pop-ups email service _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
