Cleantron developed a groundbreaking battery system that can facilitate the transport energy transition. Electric Driving is ‘in’, but in many Cities the charging infrastructure can never be expanded sufficiently to offer access to all future users. This impedes the further advance of (light) electric vehicles. An existing remedy, the interchangeable battery, causes vehicle performance restrictions that makes it suitable only for e-bikes and e-scooters. Cleantron has developed the technology that allow the necessary increase of as well Capacity (range) as Power (acceleration & speed). This makes it typically very suitable for Urban Mobility (compact cars and motorcycles).
