Maybe not. An EVSE requires an AC cable and data cable. An intelligent outlet would still require the same two cables. In addition, a specialty intelligent outlet would cost $100 - $200 (guesstimate). However, the high cost is the installation cost and maintenance cost. These costs are 2 to 4 times the cost of an EVSE and sometimes more when installed in an existing structure. High installation and maintenance cost are a problem with developing an EV charging infrastructure. One gas fueling station with multiple pumps can service 1000s of vehicles. In addition, the gas station can have a convenience store that makes money and can paid for its land use. A single EVSE that has a usage rate of 50% or less with no other associated services is a money losing device. Thousands of EVSEs scattered through out a city is a maintenance nightmare for the system owner. In addition, it is a security nightmare. Scammers put devices on gas pumps to grab credit card numbers and these pumps are at a manned location.
The answer is to charge at home with a NEMA outlet or install induction charging stations. However, for induction charging to work efficiently, you need higher frequency chargers. Remember the EV1 induction charging paddle. The system operated at 400 HZ. It was 100% safe. Drop the paddle is a pool of water and everything was OK. ________________________________ From: EV <[email protected]> on behalf of brucedp5 via EV <[email protected]> Sent: Saturday, November 5, 2016 6:00 PM To: [email protected] Subject: [EVDL] Cheap L2 charging in parking places: Bolt EV's In Production Peri sez: >cheaper than providing L2 charging in parking places< As it stands, it is not cheap to install a j1772 EVSE at each parking spot. What is currently cheap to implement, is to install a NEMA 6-20 outlet at each of several parking spots like: https://images-na.ssl-images-amazon.com/images/I/41lMtMF8U-L._AC_UL160_SR160,160_.jpg using a weather tight outdoor enclosure (like): http://www.pplmotorhomes.com/parts/rv-power-cords/weatherproof-male-receptacle.jpg But the problem with that is those outlets would be dumb, meaning they would be 'on' providing 208-240VAC 16A to any load plugged into them. That would not be what the host would want, as they would like to data-log who is plugging in (to bill them the kWh's used), know how long the plugin was plugged in, and know which plugins are jockeying around to use a EV charging space (so they would know if they need to install more outlets, etc.). In other words, the host wants to know what is going on and who to bill, same as they can do with the current more costly j1772 EVSE (i.e.: coulomb/chargepoint EVSE, or its EVSE competitors that offer such data logging, etc. *Business Opportunity Alert Now, if there was a smart (power box) product available off the shelf, that would not provide power until it knew the ID of the plugin (a unique ID for each plugin), that is plugging in to an outlet (something liken to the plugin wifi or bluetooth handshaking/being-interrogated). Perhaps the plugin's vin could be encrypted and sent so the host would know who to bill according to who owns the plugin (as in billing the owner's address). If a different driver abusively unplugged the 1st driver to not have to wait for the 1st to finish charging, the billing would know to stop the charges to the 1st, and bill the 2nd for their use, etc. Software could easily allow the owner at that complex to setup an account, so the driver could manage their plugin use (specify max power as they have a 200+mi EV, or only charge at L1 since they have a pih or do not need much of a charge, etc.). But (as far as I know), right now, there is no plugin vehicle ID method in place that could be sent along the unpowered AC line to said (power box) product. Use of that box would make L2 charging a whole lot cheaper for the host to install, implement, and possibly, and lot cheaper to use existing available power (would not need to spend money to add more AC power lines/breaker-boxes, etc.). Meaning, use of said (above proposed) product with another product already available (see): http://electric-vehicle-discussion-list.413529.n4.nabble.com/EverCharge-makes-smart-use-of-limited-AC-power-to-charge-multiple-EVs-tp4684072.html Electric Vehicle Discussion List - EverCharge makes smart use of limited AC power to charge multiple EVs<http://electric-vehicle-discussion-list.413529.n4.nabble.com/EverCharge-makes-smart-use-of-limited-AC-power-to-charge-multiple-EVs-tp4684072.html> electric-vehicle-discussion-list.413529.n4.nabble.com EverCharge makes smart use of limited AC power to charge multiple EVs. https://www.fastcoexist.com/3064354/this-startup-makes-it-easier-to-charge-electric-cars-in-apartment-buildings This Startup... EverCharge makes smart use of limited AC power to charge multiple EVs Oct 14 2016 The above product would be useful to older apartments, condos and townhome complexes that were not built-out/designed with EVSE in mind. That smart power use box would allow the power not used by plugins drawing less charging power (at the end of their charge), to increase the shared AC power going to other plugins (smart use of limited AC power: those plugins charging at L1 could be bumped up to charge at L2-3kW, etc.). Sadly (as far as I know), there is no plugin vehicle ID method that would do the above, so that makes my idea just another item to be added to the EV-driver's wish-list (another of brucedp's pipe-dreams?). I would hope those automaker-reps lurking (reading our posts) would take note of the idea, and run with it, as it can only help future plug drivers: easier to send who is plugging in and where, etc. Imagine some steals a plugin, drives it to any EVSE, and as soon as they plug it in, its ID is 'made'(known) as to where it is, etc. For EVLN EV-newswire posts use: http://evdl.org/evln/ EVDL EV News Archive - Electric Vehicle Discussion List<http://evdl.org/evln/> evdl.org EVLN - EV News Archive Edited by Bruce {EVangel} Parmenter: EVLN: home | help | archive | news | privacy policy | terms of service {brucedp.0catch.com} -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Bolt-EV-s-In-Production-tp4684295p4684310.html Electric Vehicle Discussion List - Bolt EV's In Production<http://electric-vehicle-discussion-list.413529.n4.nabble.com/Bolt-EV-s-In-Production-tp4684295p4684310.html> electric-vehicle-discussion-list.413529.n4.nabble.com Bolt EV's In Production.
