Energy on-board supply network operating method for commercial vehicle, involves conditioning voltages using non-linear elements such that charging unit charges energy storage for voltage rise by increased withdrawal of energy from network

摘要

The method involves detecting voltages (U1-U2) by measuring units (Hu1, Hu2) for controlling an output voltage and an output current of a charging unit. A charging current (Idcdc) is determined and produced for an energy storage e.g. battery, based on the detected voltages. The voltages are conditioned using non-linear elements (SL1-SL2) e.g. signal value limiters, such that the charging unit charges the storage for a voltage rise by increased withdrawal of energy from an energy on-board supply network and/or for a voltage drop by reduced withdrawal of the energy from the network. Independent claims are also included for the following: (1) a device for operating an energy on-board supply network for a motor vehicle (2) a computer program product comprising instructions for performing a method for operating an energy on-board supply network for a motor vehicle.
