ENERGY-EFFICIENT ELECTRICAL POWER DISTRIBUTION IN MAINS-CONNECTED BATTERY MACHINE

An electrical power distribution system is disclosed. A line converter is connectable to a mains power source and an on-board battery. An electronic control system is configured to control the line converter. A first sensor arrangement is configured to measure electric current into or out of the battery. A second sensor arrangement is configured to determine a current battery voltage. The electronic control system is arranged to receive a charge/discharge power request and control the line converter to regulate the line converter output voltage using a voltage reference obtained from a setpoint electric current into or out of the battery and the measured electric current into or out of the battery, where the setpoint electric current into or out of the battery is derived as a quota of the charge/discharge power request and the determined current battery voltage.
