From the successful conversion of a Porsche 914
into a battery electric vehicle
), MIT's Electric Vehicle Team
are now working on the conversion of a Mercury Milan Hybrid
into a quick-charging BEV. Instead of the typical 10 to 12 hours
for a full charge, the MIT team is looking at an 11 minute charge-time
for their BEV, dubbed "elEVen
," and they're blogging in detail about their progress
The Porsche conversion cost $60,000 plus labor for a two-seater that goes from zero to 100 km/h (~62 mph) in 23 seconds, whereas the BEV Milan conversion has a goal of < 9 seconds from zero to 60 mph and a price tag of $200,000 (but much of the materials were donated and the Electric Vehicle Team isn't paid). The batteries alone take under half of the total cost, at about $80,000, but this cost should go down as the market for lithium iron magnesium-phosphate batteries increases.
The amazing charge time requires 350 kilowatts, available through a direct connection to MIT's power plant. Though this kind of power isn't available on a residential level, the dilema of rapid charging stations and vehicles was seen as "a chicken or the egg scenario," with the MIT team showing the feasibility from the vehicle side.
