German carmakers support a modular connector system for EV charging
In a statement, the brands said that a globally integrated standard is necessary to ensure that customers always have direct and easy access to the energy grid, independent of vehicle brand and supplier of electric energy.
The statement said: 'Comparable to the standard established for gasoline dispensers and compatible filler necks, a common, worldwide used charging connector and the appropriate data interface are an important milestone on the journey to a ubiquitous e-mobility. This is the only way customers receive the opportunity along the lines of the existing gas station network to “refuel” energy for their cars everywhere without additional adapters. Therefore, the setup of a functioning infrastructure is an essential requirement for the customer-friendly individual mobility of the future.'
The company development directors said that they have decided to conceptualise a modular connector system made from two parts: the core of the connector system has been submitted for standardization under the designation IEC 62196-2 Type 2 for single- up to three-phase charging with alternating current (AC). An extension for direct current (DC) is currently being developed.
The modular connector system would be suitable for all standard charging scenarios, from single-phase charging at a regular domestic socket outlet to three-phase charging at private and public vehicle charging stations.
The carmakers added that the safety of the system is guaranteed even in case of dirt and adverse weather conditions. A mechanical locking mechanism effectively prevents unintentional interruption of the charging process.
Audi, BMW, Daimler, Porsche and Volkswagen are already working on the next steps of standardisation and added that they are actively looking for a dialog with other OEMs, utility providers and network operators.
