Vehicle exchange guidance device and vehicle exchange guidance method

摘要

PROBLEM TO BE SOLVED: To guide vehicle exchange of battery for prolonging life of the battery when a plurality of vehicles having electric motors driven by the battery as driving sources are operated.SOLUTION: Vehicle use history data of respective vehicles Cr for business use are collected to detect predicted life of the battery (step S12), and a vehicle whose predicted life of the battery is shorter than a target life is an exchange vehicle Cc which needs life prolongation, and a vehicle whose predicted life of the battery is longer is a vehicle Cn which does not need life prolongation. For each of the exchange vehicle Cc which needs life prolongation, the vehicle Cn which does not need life prolongation whose predicted life at the time of exchange after the battery is exchanged is longer than the target life is identified as an exchangeable vehicle (steps S20 to S32). With respect to combinations of the exchange vehicle Cc which needs life prolongation and the exchangeable vehicle, a combination in which average value of predicted life of all the vehicles Cr for business use after exchange becomes the longest when the respective combinations are adopted is identified, and this is presented as a vehicle exchange pattern (steps S40, S42).
