The most beautiful story about EV's (old but gold): The world's largest electric vehicle does not need to be charged. And thats not all, it even returns 77 megawatt hours back to the grid every year. The world's largest electric vehicle on wheels is the new eDumper dump truck. Due to the special area of application and local conditions, this electric vehicle does not have to be charged on the power grid and even feeds around 77 megawatt hours into the power grid every year. Illnau (Switzerland). The electric transformation not only affects electric cars, but also various other vehicles such as ships and airplanes. But other means of transport, such as dump trucks, can also be powered electrically - as the eDumper from Switzerland impressively demonstrates. The dump truck, which weighs around 110 tons (fully loaded), runs purely electrically and helps save around 130 tons of CO2 or over 50,000 liters of diesel every year. In a quarry in Biel, Switzerland, the eDumper transports around 60 tons of lime and marl rock from the higher mining area to a lower transport system with each trip. The eDumper is electrically powered for empty travel uphill. When going downhill, the lithium batteries recharge by recuperating the braking energy and thus generate more than enough charging current for the return journey. Due to the 13 percent gradient, the eDumper can only reach its destination when fully loaded by braking. The eDumper produces around 200 kWh around 20 times a day, which, after deducting the drive energy required by the vehicle and the operation of the cooling systems and hydraulic pumps, which should not be underestimated, results in an annual surplus of around 77 megawatt hours, which is fed into the public power grid.
