Electricity supply for vehicles has electrical consumption measuring device for switching in linear supply for low consumption state and chopped supply for high consumption state

摘要

The system comprises a battery (1) and a device for measuring electricity consumption (5,7) on the vehicle electrical circuits (6,6'). For the high consumption state, a chopped supply (3) is switched (2) in to feed all the electrical circuits. When the vehicle is out of service and consumption is low a linear supply (4) is switched in to feed all circuits An Independent claim is also included for a method of switching between linear and chopped electricity supplies according to the size of the measured electrical consumption
