Mahle, Siemens to Jointly Develop Wireless EV Charging

Two technology giants sign a declaration of intent to team up in developing wireless charging systems for electric vehicles.

Mahle and Siemens plan to jointly develop and test complete infrastructure and automotive engineering systems. One area of focus will be promoting technological standards for inductive charging technology.

Mahle says it has reinforced its development activities in the field of wireless charging in recent years, including two projects funded by the German Federal Ministry for Economic Affairs and Climate Action. One project aims to develop a cross-manufacturer inductive charging system for vehicles. In the second project, a standardized measurement method for the electromagnetic compatibility of inductive systems is being developed.

The technology group already is on the market with its chargeBIG cable charging system. It claims this charging management system can be integrated into existing infrastructure at low cost and without lengthy conversions. The system is designed for areas where EVs are parked for extended periods of time, for example in company parking lots, at airports or in the underground parking ramps of large residential complexes.

Harald Straky, vice president for global development at Mahle in the area of mechatronics and electronics, says: “We are very pleased to have found a strong partner in Siemens in order to make major advances in inductive charging. The combined experience of both companies gives us a clear competitive advantage.”

Stefan Perras, head of predevelopment and innovation for charging infrastructure at Siemens, adds: “Wireless charging of electric vehicles is emerging as a major market for the future. In addition to making life considerably easier for drivers, who no longer have to fiddle with cables and connectors, it is a crucial requirement for the autonomous mobility of tomorrow. The transfer efficiency of wireless, inductive charging is comparable to plug-in systems.”
