Some related projects from the internet: Reference designs<\/a> My daily commute is 8 miles one way, reaching a max speed of 55mph (usually only for 3 miles and only in the morning going to work \u2013 never in the evening – ATL traffic!)<\/p>\n\n\n\n Minimum system performance is a range of = 16 miles (round trip to work) reaching a top speed of 55mph for about 30-40% of time. Daily recharge option.<\/p>\n\n\n\n Ideally would like to be able to make a round trip to the airport. ATL international is 40 miles door to door from my house, most of the way is freeway at 55-65mph. The ideal would be able to make the trip there and back (80 mile round trip), but an option could be talk to some of the off site parking lot folks and see if a recharge option could be found. Would definitely be good promotional opportunities here…<\/p>\n\n\n\n Target design range = 80 miles spending 70%-80% between 55-65 mph.<\/p>\n\n\n\n This design would require significant power and capacity to achieve and the question about the aerodynamics of a VW bus becomes serious consideration.<\/p>\n\n\n\n An intermediate design (using recharging at airport parking lot) would reduce the design to 40 mile range spending 70-80% at 55-65 mph \u2013 much easy to achieve and similar to existing designs and builds found on the internet.<\/p>\n\n\n\n Starting the design considerations with this in mind will plan on specify components with good ranges above our initial application to allow growth in to hopefully the ideal design if not achievable in the first phase.<\/p>\n\n\n\n Design changed driven by failing Lead Batteries (old) and exploded controller (Logisystems apparently are not as good as they claim)<\/p>\n\n\n\n My daily commute is now 20 miles, with easy recharging options at the office. However strongly prefer to charge at home (cheaper) – existing design should cover this.<\/p>\n\n\n\n After several years of on\/off work, deciding to re-invest in solving the poor lithium performance. Aim is to replace battery pack as cleanly as possible (and BMS) targeting 80-90 mile range.<\/p>\n\n\n\n Based on existing projects<\/p>\n\n\n\n Refinements after discussion with David<\/p>\n\n\n\n Based on the battery selection, here is first on road implementation<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Project design Research Some related projects from the internet: Reference designsModeling: EV calc model 2008 Original goal My daily commute is 8 miles one way, reaching a max speed of 55mph (usually only for 3 miles and only in the morning going to work \u2013 never in the evening – ATL traffic!)
