Title:
A SYSTEM FOR CHARGING BATTERY OF AT LEAST ONE ELECTRICAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2016/000221
Kind Code:
A1
Abstract:
It provides a system for charging a battery of at least one electric vehicle, comprising: a first converter, being adapted for supplying a first DC voltage; at least one transformer; at least one second converter, each of which is coupled to an output of the respective one of the at least one transformer for supplying a second DC voltage; and a first controller; wherein: an output of the first converter is arranged to be connected with output of the respective one of the second converters in series so that supplying a combination of the first DC voltage and the second DC voltage as charging voltage respectively for the electrical vehicle batteries; and the first controller is adapted for controlling the second converter in consideration of measurement of charging current to the electrical vehicle battery to which it supplies the charging voltage thereby adjusting the second DC voltage in response to the electrical vehicle battery. By having the electrical vehicle battery charging system, the total number of the electrical vehicle battery that can be charged at the same time has correlation with the number of the second converter
