At over 4700 lb Tesla is hardly the benchmark for efficiency. My 2260 lb ev 5 1/2 year average energy use is 216 Wh/mile from the wall, with about 50% travel on highways at 55 - 65 mph. Charger efficiency, measured several times, is 0.91, so that's about 197 Wh/mile or 5.1 miles/kWh excluding charger losses.
What I've read also says that hub wheels are a problem for higher speed vehicles due to unsprung weight, but I've no experience with them. A range of 186 miles for my vehicle would require about a 46 kWh pack, assuming 20% DoD, and not too much increase in vehicle weight due to this larger pack size - so higher specific energy cells than the 103 kWh/kg it presently has. This vehicle is supposed to be lighter than mine, but still likely will need significantly larger than 24kWh pack for 186 miles. I expect like others gone before it will not be completed, but there is always some hope. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Re-EVLN-Open-Source-Street-Legal-affordable-long-range-EV-4the-masses-tp4675590p4675605.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ 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)
