Bosch and partners develop a charging system for the cars of the future

Electric cars will soon be something like smartphones - their battery systems will become external batteries for electrical grids. Quite practical, if only not for the annoying charging cables. Both rain and thunder - the driver must connect the electric car to the charging station with a cable. But that is about to change: Bosch, in its role as project coordinator for BiLawE, is conducting research with the Fraunhofer Institute and GreenIng GmbH & Co. KG is an innovative concept for inductive charging of vehicles, i.e. without physical contact - through the magnetic field when the vehicle is parked at the charging station.

New technology will make electric vehicles even greener and electric grids more sustainable. One of the challenges they face is that energy from renewable sources such as wind, sun and water is subject to natural fluctuations. In this regard, the consortium, joined in the state-funded research project BiLawE, is developing an inductive charging system to create an intelligent structure for the continuous use of renewable energy sources.

Their solution is based on batteries for two-way electric vehicles - the batteries use a powerful smart charging system to store energy, but they can return that energy back to the grid if needed. If strong sun or wind generates peaks of energy, electricity will temporarily accumulate in car batteries. With high clouds and no wind, the energy will be returned to the grid to cover the needs. “For the system to work, electric vehicles need to be plugged in as often and as long as possible. This, in turn, requires a permanent infrastructure - special induction charging stations connected to national and regional power grids, as well as isolated networks supplying only limited areas, ”explains Philip Schumann, project physicist at the Bosch Research Center in Renningen. near Stuttgart.

Wireless charging while parking

The advantage of the induction system is wireless charging. Since no jumper cables are used, cars can be plugged into the mains more often, and bi-directional charging stations can unload and stabilize it even when electric vehicles are in motion. Thus, the project aims to create a concept for the production of components for charging systems as well as a business model for various network services related to energy recovery.

Strong partners

The BiLawE research project (German for two-way economical inductive charging systems in the grid) has received funding of 2,4 million euros from the German Federal Ministry for Economic Affairs and Energy under the ELEKTRO POWER II program and is supported by the leading German southwest cluster Electromobility. In addition to the coordinator Robert Bosch GmbH, the project partners are Fraunhofer Institute for Solar Energy Systems ISE, Fraunhofer Institute for Industrial Engineering IAO and GreenIng GmbH & Co. KG. The project was launched at the beginning of the year and is designed for three years.

The German Southwest Electromobility Cluster is one of the most important regional organizations in the field of electromobility. The aim of the cluster is to stimulate the industrialization of e-mobility in Germany and to make the German state of Baden-Württemberg a powerful supplier of electric drive solutions. The organization brings together leading corporations, small and medium-sized companies and research institutions in a development network in four innovative areas: automobiles, energy, information and communications technology and manufacturing.
