Electrical supply system for motor vehicle, has battery charging ultra cap by direct current-direct current converter before start of vehicle on high stress than rated stress, where stress level of electrical system is determined

摘要

#CMT# #/CMT# The system has a battery (4) separated by a circuit unit during start process of an electrical system (B). The battery charges an ultra cap (2) by a direct current (DC)-DC converter (3) before start of a vehicle on a high stress than a rated stress. A stress level of the electrical system is determined during recuperation of stress produced from an electrical generator (G) and/or recuperation brakes. The electrical system stress is equal to an output stress of the generator after the recuperation process and in normal operation. #CMT#USE : #/CMT# Electrical supply system for a motor vehicle. #CMT#ADVANTAGE : #/CMT# The electrical supply system is designed without large changes with good starting ability and charging of the battery with fewer losses and recuperation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of an electrical supply system.'(Drawing includes non-English language text)' B : Electrical system G : Electrical generator 2 : Ultra cap 3 : Direct current-direct current converter 4 : Battery.
