Periodic Reporting for period 1 - MobileBattery (Mobile Energy System for recharging, energy buffering and long-distance travelling)

Reporting period: 2015-04-01 to 2016-03-31

Summary of the context and overall objectives of the project

Objective of this business innovation project is providing market readiness for our Mobile Energy Systems (MES). BVB INNOVATE has developed totally new mobile energy sources in co-operation with Fraunhofer Institutes, and universities. They are able to deliver clean electric energy to a broad variety of grid, off-grid and mobile applications. Technically, these Mobile Energy Systems are powerful 85 kWh Li-ion batteries ‘on wheels’. MES batteries can be charged with clean energies from rooftop photovoltaic installations, as well as from wind power or combined heat and power plants or from the grid. Main use-cases are:

1. Mobile recharging – ‘Charging as a Service’: The Nomad provides solutions for all following challenges in today’s electric mobility world due to the possibility of mobile recharging. Many companies offer zero emission vehicles to their employees. A huge penetration of electric vehicles in a company fleet provokes challenges in energy distribution and management. Expensive grid extension and strict charging rules need to be followed for enabling the mobility of every battery electric vehicle (BEV) user. Furthermore car sharing operators with electric vehicles as offered by renowned car manufacturers are asking for a solution to rapidly charge stranded e-vehicles. Other interested users are towing services. So far empty cars are transferred to charging stations where they need to linger for the time of recharging. Our solution rapidly recharges the battery so that the driver can continue their trip.

2. Home and mobile energy – ‘Destination and Home Charging’: Every car park operator, e-car driver or owner of a home (with a rooftop PV installation) can make efficient use of the Mobile Energy System: While “parked”, the MES battery will serve the function of intelligent safe back-up power for the estate/home, with additional “smart home” functionality. Airport operators, companies, car park operators and private persons showed interest and will partially test Nomads during the project phase. Private persons can additionally attach to the Nomad to their battery-powered electric vehicle (BEV) for a long weekend trip. An 85 kWh mobile battery is capable of taking a small electric car up to 400 kilometres.

3. Autobahn rental – ‘Charging While Driving’: We will offer MES batteries for rental at major arterial roads across the country. Owners of e-cars will have the option of renting rather than buying range-extending power packages. If a Munich-based e-car driver decides to go to Berlin, he will ‘hook up’ an battery at an Autobahn station just outside Munich, drop it off at a station outside Berlin, and then have the freedom and ‘lightness’ of a small car in the target city.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

For achieving the aim of producing prototypes a process has been set up which were kicked-off by drawing sketches and preliminary designs of the Nomad. After choosing the final design some renderings have been produced and the design has been protected. In a later stage, the technical drawing with all relevant details was developed in a very close cooperation with the designer. Last step is the production of the prototypes.

Sketches
Sketches were drawn by Lorenzo Cordella, design student from Politecnico di Milano. Sketches cover essential considerations such as surface design, size of the inner volume, colours, functions, etc. Different designs have been assessed and chosen in collaboration between designer and management team.

Rendering
Different renderings have been produced for obtaining a view as close as possible to the perception produced by the real world scene. Those renderings were published on the homepage and were included into the set of presentations, which are regularly presented to potential customers, investors and experts in the field of electric mobility.

Design protection
The unique design of the Nomad will be one of the core IP that will be commercialized by Nomadic Power. This is why the filing of the design protection was one of the first tasks after completing the design study in July 2015.

CAD model
In Autumn 2015 a design engineer joined the team and translated the design into a technical drawing with all relevant specifications such as layout of the undercarriage and chassis. The technical drawing also contains all electric connections and charging standards such as CHAdeMO, CCS, Typ2, Schuko and CCE.

CAD model rendering
The rendered CAD model looks quite realistic as all technical details can be seen on the picture. The CAD development has been done in a very close collaboration with the designer, as a design oriented transfer was desired.

Prototype
The very first prototype is produced with additive technologies by laser sintering. Further chassis will preferably be done with silicone moulding technology which is estimated to be the most economical production method. The first prototype is expected to be finalized in April 2016.

Battery development and system integration
A modular battery was designed and developed. The battery modules will be manufactured and aggregated to lithium ion battery. The battery will be charged by a bi-directional on-board charger. DC fast charging will be performed by DC/DC inverter.Two main standards (CCS and CHAdeMO) will be enabled covering most of the electric vehicle in the EU.

Commercialization
Besides the technological development substantial financing progres has been made. Negotiations are currently underway with venture capitalists, financing banks, and other institutions. 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 finetuning of the business model. As a result, first agreements with customers could be closed. One shared e-fleet operator, a subsidery of a renown German car manufacturer will test the prototypes in real environment. Test locations will be Berlin, Munich, and Copenhagen.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

Broad press coverage could be achieved, e.g. featured in FORTUNE, a renowned US American business journal.
The importance of everywhere charging was clearly highlighted in the article. Nomads will be able to recharge electric cars everywhere without the need of fixed grid infrastructure. Recharging of distributed e-car fleets was identified as an important first use case. Charging as a service will play a predominant role in our business model in the near future.
Nomadic Power will build up its role as an enabler for distributed shared e-car fleets. Everywhere fast charging will be crucial for the profitability for such business models and for the overall adoption of shared mobility concepts.
