ZEC-Bike project: "Zero-emission Cargo Bike for Smart Cities"

Within the ZEC-Bike project, a smart — meaning connected and digitalized — and purely electric emission-free cargo bike concept (L1E class) was developed for use in cities and a prototype was built. In order to determine requirements and possible applications, a business model analysis was carried out in the application areas of sharing, delivery services, depots, factory transport, and package delivery/couriers.

Beside the vehicle design, the project’s technical focus was on two other topics: Firstly, an efficient and fast-charging battery was developed and implemented, based on a new battery cooling system that is suitable for two-wheelers. Secondly, an all-wheel-driven powertrain was integrated and — based on this — both a safety and efficiency-oriented operating strategy for the cargo bike as well as associated assistance functions were developed and implemented. The project of the research partners was supported by the companies EMB Elektromaschinenbau GmbH, Mittelbiberach, and VARTA Microbattery GmbH, Ellwangen, that were involved as subcontractors.
