E-mobility faces two major challenges that are directly linked: the lack of infrastructure and the range of electric-powered vehicles. The ICC (Inductive Charge Inverter) charging system developed by Stercom offers a solution for both aspects through inductive fast charging. "ICI shows its potential especially in public transport. Buses usually travel the same routes in cities, passing central hubs. These locations are ideal for a kind of inductive pit stop, "explains Robert Sterff, Managing Director of Stercom Power Solutions. As soon as a bus has approached one of the stops with an integrated ICI system, the battery is partially charged with up to 22 kW in a fast process.
Fast charging through interaction of ICI and supercaps
The installation of several of these charging stations along the bus line creates the necessary infrastructure, which in turn solves the problem of reach. The possibility of continuous partial charge at the stops, the size and range of the battery is no longer crucial, but the ability to fast charge. "The fast partial charge at the stops is only possible through the use of high-performance batteries. Frequently, supercaps are used for this, which load themselves up again in 15 minutes, say at the last stop, "says Sterff. The reduction in battery size also ensures less loss due to the lower heat generation, more space for the payload and so finally for a better cost / benefit ratio. The size of the battery also acts through the smaller mass to be accelerated energy-saving and environmentally friendly.
Larger air gap between coils possible
The system developed by Stercom Power Solutions enables very efficient energy transfer even over large air gaps of up to 20 cm thanks to state-of-the-art silicon carbide circuit breakers and optimized coil control. So, in addition to buses, for example, high-legged SUVs can be loaded without lowering the secondary coil in the vehicle extra. The new, more powerful ICI system features automatic coverage detection, enabling easier and faster positioning of the vehicle above the charging station as a prerequisite for optimal fast charging.
