Multi-Moby and Bitron Electronics cooperation
Multi-Moby is an ambitious project part of the European Commission's Horizon 2020 program, aiming at quickly finalizing the results of a cluster of European projects addressing the development of technology for safe, efficient and affordable urban electric vehicles.
To achieve the ambitious Multi-Moby targets, a consortium was founded, involving leading industrial and R&D organisations in several disciplines, such as semiconductors, vision systems, artificial intelligence, ICT systems, vehicle design and simulation, batteries, power electronics, low- and mid-voltage powertrains, charging systems and vehicle management.
A fleet of multi-passenger and multi-purpose commercial vans will be manufactured assuring:
- Best-in-class safety for occupants and Vulnerable Road Users (VRUs) protection as required by the M1/N1 regulations
- Driving automation capabilities by adopting the most extensively tested sensing and computing platforms, with the addition of low-cost scanning and night vision functionalities
- High efficiency 48V and 100V powertrains adopting the most advanced power semiconductor technologies, including Si, SiC and GaN
- Robust battery packs based on hybrid cells with specific energy close to 200 Wh/kg at pack level
- On-board charger integrating a DCxxV-DC12V converter optimized for the two voltages of interest
- Advanced Electric Electronic (EE) architecture with secure procedures for remote updates and upgrades of the firmware and predictive maintenance, by applying advanced artificial intelligence (AI) methodologies
- Application of low-cost, flexible, agile and lean manufacturing through a low-investment micro factory concept
- Competitive price positioning with respect to existing and forthcoming fully electric urban passenger and commercial vehicles.
Bitron Electronics, specialised in designing and manufacturing of electronic systems and devices, as active part of the consortium, is developing a Wall box solution with single-phase AC input (230Vac) and output voltage programmable starting from a minimum value of 48V, as required from the project.
To maximize the power conversion efficiency new Infineon SIC Mosfet devices have been used. This system is also able to deliver output voltages up to 500Vdc, at limited output current. The charging standard is CCS2, according to the European Standards.
