Electric car ‘eVe’ is powered by a Li-ion battery pack, max speed 140 km/h (87 mph), range is 800 km (500 mi)

Sunswift is a team of engineering students from the University of New South Wales who designed and built a car that holds the Guinness World Record for the fastest solar-powered vehicle. The team hopes that its newest electric car, eVe, will break a 20-year-old electric vehicle record for the highest average speed over a 500 km (310 mi) distance

Electric Car Specifications

eVe is powered by a Li-ion battery pack, an enormous bank of off-the-shelf laptop computer batteries, that drives a pair of custom designed motors with a staggering 97% efficiency. The motors were designed by the Australian national science agency, CSIRO. A solar array consisting of high efficiency flexible thin-film silicon PV cells provides up to 800 Watts of power on a sunny day. Regenerative braking replenishes the batteries, recovering up to 80% of the braking energy.

The car is capable of traveling 140 km/h (87 mph). Driving at highway speeds, eVe uses the equivalent power of a four-slice kitchen toaster. Its range is 800 km (500 mi) using the battery pack supplemented by the solar panels, and 500 km (310 mi) on battery power only.
