Method for managing electrical supply network of e.g. electric car, involves determining charge state of house battery, and modifying voltage setpoint of output of voltage converter according to charge state of battery

摘要

The method involves initializing a managing process (E1) when a voltage converter does not supply current into a circuit. A charge state of a house battery i.e. lithium-ion battery, is determined (E1-1). A voltage setpoint of an output of the converter is modified (E1-2) according to the charge state of the battery. The converter is started-up (E2-1) with application of the voltage setpoint such that output voltage of the converter at the output is equal to or represents the voltage setpoint. The battery is charged (E2-2) by the converter during an operation (E2) the converter. The voltage converter is designed as a direct-current (DC)/DC voltage converter. Independent claims are also included for the following: (1) an arrangement for managing an electrical supply network of a car (2) a car (3) a data recording medium comprising a set of instructions for performing a method for managing an electrical supply network of a car (4) a computer program comprising a set of instructions for performing a method for managing an electrical supply network of a car.
