Electric automobile charge scheduling method and charge scheduling device

Abstract

This electric automobile charge scheduling method uses a plurality of connected station management devices which manage charging equipment arranged in a charging station and an vehicle-mounted information device, and comprises the steps of: ascertaining the present location of an electric automobile, using a station management network which connects a plurality of station management devices which manage charging stations' charging infrastructure and a vehicle-mounted information device; acquiring information including the locations of candidate charging stations which are candidates for carrying out a charge on the basis of the present location and information including waiting time of the candidate charging infrastructure and the price of the charge; displaying the candidate charging stations; selecting and setting the candidate charging station with which carrying out the charge is desired; and scheduling the candidate charging station on the basis of the setting. It is thus possible to increase usability, allowing charge scheduling which takes a user's decisions and preferences into account, as well as eliminate actual risks of batteries having insufficient remaining capacity and the emotional concerns therewith, and improve system response time and operational reliability by distributing processing load on the system side and the vehicle side.

Description

technical field [0001] The present invention relates to a charging reservation method and a charging reservation device when charging an on-vehicle battery of an electric vehicle by using a charging device installed in a charging station. Background technique [0002] In recent years, electric vehicles have gradually become popular, and the development of charging equipment for charging vehicle-mounted batteries has been gradually expanded, and the deployment of public charging stations has been promoted. However, at this stage, compared with engine vehicles that use gasoline or diesel, LNG (liquefied natural gas: liquefied natural gas) as fuel, electric vehicles can travel a shorter distance, and compared with gasoline stations (gas stations), charging Station facilities are few in number. Therefore, when driving an electric vehicle for a long distance, it is necessary to know the charging stations that can be charged in advance or know the charging stations that can be ch...

Problems solved by technology

In addition, when driving an electric car on a road for the first time or in a traffic jam, many users feel uneasy about the remaining battery power.

Moreover, since the charging time of the battery is long compared with the refueling time of gasoline, how the passenger (driver) spends the charging period is also a problem.
