Zero Fuel Airplane, powered by Kokam battery

On July 26, 2016, the groundbreaking solar-powered aricraft, Solar Impulse 2 successfully completed the final leg of its trip. This project, which took off on March 9th, 2015, involved flying around the world, landing in 17 cities and recording a total distance of 43,041km using only free, clean solar energy. The Solar Impulse 2 relied on four 38.5 kWh systems comprised of Kokam Ultra High Energy NMC batteries to power the zero fuel solar airplane.

The battery system used for the Solar Impulse2, powered by Kokam’s UHE NMC technology, featured high energy density and efficiency along with the ability to operate over a wide range of temperatures, different levels of humidity and endure high pressure conditions. These factors led the Solar Impulse team to select Kokam’s NMC battery technology for both the first version of the Solar Impulse1 and the second project.

The project originated when Bertrand Piccard started researching a way to fly without harming the environment, after realizing that his hot air balloon required 3.5 tons of fuel to fly. With the help of Andr? Borschberg in its creation, the second pilot, today the 1.6 ton Solar Impulse is flying around the world, powered only by solar power.

Carrying 17,000 of high performance solar cells on top of its wings together with Kokam’s energy dense lithium ion batteries, the plane can fly not only during the day but also during the night without a single drop of fuel. Kokam’s batteries are proven to be not only highly efficient, but also lightweight and safe.

The Solar Impulse completed its first flight in 2009. In 2010, it became the world’s first solar panel powered aircraft to be flown at night with a pilot on board. When it took off at 7a.m. from Switzerland and successfully landed at 9 a.m. the next day, it set a record that day. It was the longest flight made by an aircraft powered solely by solar panels and Kokam’s lithium ion batteries.
