Title:
ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2019054726
Kind Code:
A
Abstract:
To achieve solution and reduction of various problems (particularly, problems concerning a price, a weight, a charging time, a service life) relating to a high-capacity secondary battery as a largest task for popularization of an electric vehicle.SOLUTION: A high-capacity secondary battery, which has an electric power accumulation capacity which is necessary and sufficient for energy saving travel (equivalent to travel at a constant speed travel fuel consumption) which covers an average travel distance of one day, is mounted on an electric vehicle, and charging to the high-capacity secondary battery is performed, in principal, by normal charging during a parking period at a place of a home of an EV owner or the like at which long time parking is possible. During travelling, a travel possible distance (in energy saving travel) by residual electric power and a residual distance between a current place and a destination are periodically specified and compared, and at a suitable point of time after the point of time when it is proved that a deficiency occurs in residual distance travel to the destination by the residual electric power, access to a charging station, which exists in the middle of a route to the destination, is performed thereby charging electric power of a minimum necessary amount.SELECTED DRAWING: None
