Device for determining cost-optimized charging of electric car based on navigation data, has charge determining device determining required charging of battery of car to reach destination based on battery charge state and navigation data

摘要

#CMT# #/CMT# The device has a battery (1) including a charge state output device for outputting charge state of the battery. A navigation system (2) includes an energy calculating device (22) for calculating energy requirements of an electric vehicle i.e. car, based on navigation data. An energy management system (3) includes a charge determining device (31) to determine required charging of the battery of the electric car to reach a target destination based on the charge state of the battery and the navigation data. #CMT# : #/CMT# An independent claim is also included for a method for determining cost-optimized charging of an electric vehicle based on navigation data. #CMT#USE : #/CMT# Device for determining cost-optimized charging of an electric vehicle i.e. electric car, based on navigation data. Can also be used for a hybrid car. #CMT#ADVANTAGE : #/CMT# The charge determining device determines the required charging of the battery of the electric car to reach the target destination based on the charge state of the battery and the navigation data, thus avoiding frequent complete charging of the battery, and hence improving the life of the battery while saving the cost of charging the battery. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of a device for determining cost-optimized charging of an electric car based on navigation data. 1 : Battery 2 : Navigation system 3 : Energy management system 22 : Energy calculating device 31 : Charge determining device.
