Power Trading is a pioneer for open and distributed software architectures, because a standardised set of Information is used to manage all relevant forms of energy within a vehicle. The communication of the price-power functions shall be made through a bus-structure, e.g. CAN. Power trading does not require one specific bus. Most architecture concepts will be supported. By increasing the complexity of energy management, which will be defined by the number of enhancement modules, the amount of data to be transmitted will increase. To transmit these data, some bytes excluding header are required. These data have to be sent with a frequency between 10 and 2 Hz. All otherdata need much lower frequency. However, the battery module requires a separate protocol. The advantage of open software and standardised interfaces is that the energy manager has not to be redeveloped, in case one component in the car will be changed or additionally installed. Even different optimisation strategies may be implemented easily. The presented concept of power trading provides optimised control over the electrical power supply by managing via CAN-bus the sophisticated interaction between the vehicle's main control units in a standardised way. The power-trader is a flexible and precious tool to achieve reduced emissions and fuel consumption with improved driveability and comfort with even increasing reliability. With the proposed BEM-system Siemens VDO ensures mobility. Our scaleable functionality and modular design fits all market requirements. The development efforts for power trading will lead to a completely new concept for supplying electrical power and will lead towards a total vehicle energy management. Although further improvements are necessary, the concepts described here will have an enormous positive influence on the introduction of new functions, auxiliary power units and x-by-wire- technologies in future vehicles.
