Funded entirely through donations, ENDURANCE took 4 months to build. The composite chassis is made from PVC pipe. It uses standard bicycle wheels and brakes. An E-bike brushless DC motor powered by three 12-volt, 18 AH SLA batteries is rated at less than 1 horsepower. It also features regenerative braking, cruise control, and reverse.
The total assembled weight is 110 pounds without the driver.
PERFORMANCE:
Endurance traveled 24 miles on 702 watt-hours of electricity (39 volts x 18 ampere hours)
702 watt hours divided by 24 miles = 29.25 watt-hours per mile
33,560 watt hours of electricity= 1 gallon of gasoline
702 watt-hours divided by 33,560 watt-hours = 2.09 % of a gallon
At today's prices of $3.20, 2.09 % of a gallon of gasoline = 6.7 cents to travel 24 miles
24 miles (or 2.09) x 47.85 (the remaining 97.91% of the gallon of gasoline) = 1148.4 MPGe
Top Speed: 18 MPH
Cost-per-mile: less than 1 penny (.29 cents)
Educational Standards Addressed:
RIDE Applied Learning Standards 1-6
ISTE-S: 1a-c, 4a-c
Common Core RST.9-10.3: Follow precisely a complex, multistep procedure to carry out
experiments, taking measurements or performing technical
tasks.
Next Gen HS-PS3- Energy: Design, build and refine a device that works within given
constraints to convert one form of energy into another form.
Great STEM projects are borne from great ideas and motivated, creative students.
The Electric Vehicle Lab (formally at Tiverton High School) a unique engineering experience in which students brainstorm, research and build radical, working Renewable Energy prototypes and projects.
