The field of fast charging is diverse. Many solutions use dedicated additional costly components for each charging type.  To push the E-Mobility market, a new system for charging is proposed comprising of E-Machine, Inverter and Boost DC/DC converter with a minimum of additional components. The new Bidirectional Charge- and Traction-System (BCTS) is capable for traction and all kinds of conductive charging with reduced system costs.  The authors have developed a cost efficient solution for E-Mobility targeting all kinds of conductive charging. It solves the chicken-and-egg problem of investment for fast charging electronics by reusing existing electronics in the car. It makes the charging station as simple as possible, which is AC charging. Furthermore all conductive charging interfaces can be used when the BCTS is installed. In this paper the authors have discussed the system architecture, the use cases and the needs and the current development status of the involved components.
