BOmobil

A vehicle project mobilises entrepreneurism in electromobility and creates new, innovative jobs in Bochum.

BOmobil is the name of the working prototype for a small delivery van developed by the University of Applied Sciences Bochum with Composite Impulse, Delphi, Scienlab and TÜV NORD, and funded through the competition ElektroMobil.NRW. The concept is driven by the demands for future regional transport of small- and middle-enterprises. The BOmobil is proof that electromobility and attractive design are not mutually exclusive.

Technologically, the prototype is a radical move away from traditional automobile concepts. A central motor has been eschewed in favour of hub motors in order to create the room necessary for a new conception of the vehicle’s interior and create the basics for everyday electromobility: seating for two, room for a standard box pallet, top speed of 130 km/h and a range of over 150 kilometres. The entirety of the drivetrain components are accommodated on the so-called “skateboard”, the load-bearing structure made of lightweight aluminium profiles riveted and glued together. This design provides the high-strength structure necessary for the crash-safety of a delivery van but also allows for flexible design variants. The battery, the traction inverter and the motors are arranged “organically” to one another, creating short wiring lengths and a low centre of gravity and the proprietary hub motors provide torque where it is needed; the smaller powertrain leaves more room for cargo. The battery uses lithium iron phosphate technology and the relatively narrow temperature range it needs to operate is provided by the vehicle’s thermal management. For this reason, choosing the proper isolating materials for the body and windows is of vital importance in order to substantially reduce the need for active cooling or heating, in comparison with conventional vehicles. The body is made of ABS and fibre reinforced plastic, which have structural as well as thermal and acoustic insulation properties. While conventional vehicles use single-pane safety and laminated glass for the windows, the BOmobil uses plastic windows whenever possible. In order to reduce costs, the chassis uses standard components from the OPEL Zafira.

After a period of inactivity around the BOmobil, there has been growing interest to produce the vehicle abroad.
