Monday briefing: EVs, electromobility infrastructure, more e-bikes and a research round-up

fort_carson_ev_chargingMore on the US military’s smart microgrid experiments at Charged EVs: bi-directional fast-chargers (giving energy storage capability) are now operational to support a fleet of electric trucks at Fort Carson, Colorado (pictured).

  • EVs should be delinked from the CAFE (corporate average fuel economy) regulations; this, in combination with controlled (off-peak) charging and implementing standards for supply of renewable electricity, gives the optimum scenario for reductions in greenhouse gas emissions and energy use, say researchers from Georgia Tech who modelled six possible EV market-share scenarios. Handy rundown at Green Car Congress; for academic reference, it’s Environmental Science & Technology (July 2013); Dong Gu Choi, Frank Kreikebaum, Valerie M. Thomas, and Deepak Divan (2013) Coordinated EV Adoption: Double-Digit Reductions in Emissions and Fuel Use for $40/Vehicle-Year. Interesting point about decoupling EVs (including, in this study, PHEVs) from CAFE, which would preclude manufacturers offering a tiny handful of ‘compliance cars’ to bring down their overall average, thus forcing them to make greater improvements in their mainstream ICE ranges.
  • Electric in Orlando: Enterprise is launching a fleet of 15 Nissan Leafs in the Florida tourist town. Customers can charge for free, with points located at hotels, convention centres, theme parks and on-street; apparently, there are about 300 public charging points in the greater Orlando area. Full story at Detroit News.
  • South America’s largest all-electric taxi fleet is in Bogota, Columbia. According to BYD, supplier of the city’s 45 e6 taxis, anyway; press release posted here at Autoblog Green.  The city has abolished import duty on all-electric private cars, buses, trucks and taxis, and reduced duty on hybrid or CNG buses and trucks from 15% to 5%.
  • The Range Rover Evoque_e is to get a three-speed axial flow transmission developed by Drive System Design/YASA Motors; this is said to be super-light and compact, and to reduce energy consumption by 10-15% compared to a single-speeder. More at Green Car Congress.
  • Nissan has started work on a new electric truck, the e-NT400 (based on the Cabstar plus Leaf powertrain). It’s said to have a range of 87 miles and is scheduled for launch next year (Green Car Congress).
  • More e-bike news: Electra (maker of retro-look urban cruiser bicycles) is now offering electric pedal-assist models. Nice story, complete with pic of requisite tattooed, bearded ageing hipster (the post-fixie target market?), at Treehugger, which also has news on Bay Area BikeShare (Boris bikes, San Fran style) and  relaunch of Copenhagen’s GoBike, the former with reference to ‘last mile’ transport.
  • Brazil’s set to be a new EV hotspot, according to research from Frost & Sullivan, which claims that 70% of the country’s car-market could be plug-in hybrids and EVs by 2020 (via Charged EVs).
  • Could car ownership go the way of the landline phone (i.e. near-obsolete)? A look at car-sharing and incorporation of the car into an integrated system from the Rocky Mountain Institute blog.
