The realm of innovation reached new heights as a solar-driven electric vehicle achieved an unprecedented feat: conquering the towering heights of the planet’s loftiest volcano. Spearheaded by the Swiss team, Peak Evolution, in collaboration with Austria’s Gebrüder Weiss transport company, this historic endeavor unfolded at the apex of Chile’s Ojos del Salado, an astonishing 6,500 meters above sea level.
Unveiling the Expedition:
The journey of this groundbreaking odyssey began with the electric truck, entirely powered by solar energy, making its way from Switzerland to Chile via Rotterdam, traversing maritime cargo routes. Starting its expedition in the Atacama region, the vehicle geared up for the ambitious ascent from the Maricunga Salt Lake, nestled at an altitude of 3,400 meters (11,155 feet).
Revolutionizing Energy Sources:
Distinct from conventional fuel sources, the expedition vehicle was crafted from the adaptable Aebi VT450 transporter. Propelled by twin 120 kW electric motors and fortified by a 300 V nominal EcoVolta lithium-ion battery with a 90 kWh capacity, it showcased an impressive range of 200 km (124 miles).
Solar Integration at Its Zenith:
The crux of this unparalleled journey lay in the truck’s integration of solar capabilities. Leveraging power from four rooftop solar panels and an additional 16 panels dispersed on the ground, the vehicle generated a combined peak power of 370 W with a striking 22.5% cell efficiency. A robust charging infrastructure facilitated the transfer of solar energy back to the vehicle, supported by five solar charge controllers and a fail-safe DC-coupled charging system.
Conquering Environmental Adversities:
Navigating the formidable terrain of the world’s highest volcano, the solar electric truck, accompanied by a seasoned team of three mountaineers, faced relentless environmental trials. Patrik Koller, CEO, and developer at Peak Evolution, celebrated the triumph as the culmination of four years of dedicated training, emphasizing the team’s unyielding determination in the face of extreme challenges.
