MobileBattery started with redefining the concept in order to achieve necessary features as fast and ultra-fast mobile recharging, convincing safety features, and the ability for streamlined mass production. The project started with the update on component level followed by systems integration. Now, we are in the phase of functional testing prior to user tests and scaling-up.
Components: A modular battery with a completely new design was developed. The battery modules use light-wight Li-ion-cell-bearing bodies with imminent safety features in order to reduce foot-print and overall weight without loosing outstanding safety features. The battery will be charged by a bi-directional on-board charger. DC fast charging is performed by a DC/DC inverter. Two main standards (CCS and CHAdeMO) are enabled covering most of the electric vehicle in the EU. We used innovative CATIA 3D Experience software to design all components, enable development accompanying validation, product life cycle management, and sharing with preferred suppliers and contract manufacturers.
System:
The prototype system integrated the modular batteries with the power electronic component on a trailer based platform. Components of chassis were produced for testing by innovative 3D printing and laser sintering. Mass production of chassis components will preferably be done by REM technology which is estimated to be the most economical production method. The prototype is under functional testing now.
Commercialization:
A shared e-fleet operator, a subsidiary of a renown German car manufacturer will test the prototypes in real environment. Test locations will be Berlin, Munich, or Copenhagen. Negotiations with other German car manufacturers are in progress. An investment readiness assessment was performed by a representative of the European Union. The final report highlighted excellent ratings, for example concerning the product readiness level. The investment readiness report leaded the way to improve market readiness of the overall system and fine-tuning the business model. Negotiations with VC and Corporate VC companies are under way. A memorandum of understanding was signed with a renowned Swiss infrastructure financing company with the aim to finance our investments as a charging infrastructure provider in the triple digit million Euro range.
