Berkeley study finds self-driving electric taxi fleets in Manhattan would deliver significant cost and environmental benefits

Green Car Congress

Using models they built and data from more than 10 million taxi trips in New York City, they found that the cost of service provided by a fleet of shared automated electric vehicles (SAEVs) would be $0.29-$0.61 per revenue mile—an order of magnitude lower than the cost of service of present-day Manhattan taxis and $0.05–$0.08/mi

Ford’s Key Life Battery test for Li-ion batteries simulates 10 years, 150K miles in 10 months, under different conditions

Green Car Congress

Leveraging some 20 years of experience and data reaching back to its early work with hybrids and the Ranger EV, Ford has developed a battery model and life validation protocol it now uses to predict how lithium-ion batteries are likely to perform under 10 years and 150,000 miles of use (40-season equivalent key life tests). Taenaka, B.,

“Big data” analysis of Beijing taxi fleet suggests maximum electrification subsidy benefit from targeting medium-range plug-in hybrids

Green Car Congress

A pair of researchers at the University of Michigan have used “big data” mining techniques to evaluate the impact of adopting plug-in electric vehicles (PEVs) in the Beijing taxi fleet on life cycle greenhouse gas emissions based on the characterized individual travel patterns. one-driver taxi versus two-driver taxi).

Berkeley Lab analysis finds autonomous electric taxis could greatly reduce US LDV GHG emissions

Green Car Congress

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have found that the per-mile greenhouse gas emissions of an electric autonomous taxi in 2030 would be 63-82% lower than a projected 2030 hybrid vehicle driven as a privately owned car and 90% lower than a 2014 gasoline-powered private vehicle.

ALTe Developing Series Plug-in Hybrid Powertrains for Conversion and OEM Applications

Green Car Congress

ALTe already has Gen 1 proof-of-concept systems running in a Crown Vic taxi equipped with a 20 kWh Li-ion battery pack. Another benefit of targeting a conversion application such as the taxi fleet is that the vehicles are all out of warranty, Thomas noted.). Gen1 System installed in a Crown Vic. Click to enlarge.

Accenture study finds PEV rollouts challenged by cost of charging infrastructure and grid management

Green Car Congress

The large scale rollout of plug-in electric vehicles (PEVs) will be hindered unless investors stimulate demand, lower the cost of public charging infrastructure and manage the impact on the grid, according to a report published by Accenture. The consumer is the most important factor in determining which business models will succeed.

ZeroAvia unveils hydrogen fuel cell powertrain for aviation

Green Car Congress

ZeroAvia plans to start supplying its platform to commercial operators and aircraft manufacturers in 2022, initially targeting up to 500-mile regional flights in 10 to 20-seat fixed-wing aircraft. It will also be more economical than conventional turbine engines, or even the battery-based systems, on the total cost basis.
