Method of providing battery replacement service and apparatus for performing the method
A method of providing a battery replacement service and an apparatus for performing the method can include collecting, by a battery data collection unit, data about a battery, collecting, by an electric vehicle data collection unit, data about an electric vehicle, determining, by a battery replacement target determination unit, a target battery to be replaced among batteries, determining, by a battery replacement timing determination unit, a replacement timing of the target battery, determining, by a battery replacement place determination unit, a replacement place of the target battery and providing, by a battery replacement service providing unit, a replacement service for the target battery.
1 . A method comprising:
via a processor of a computing device:
collecting battery state data of a battery in an electric vehicle,
collecting electric vehicle data of the electric vehicle, the electric vehicle data including data regarding route information of the electric vehicle,
performing a battery diagnostic test on the battery via:
executing a current capacity-based determination unit to measure a current capacity of the battery using current integration during charging and discharging of the battery to determine a first state of health (SoH) of the battery based on the current capacity, and
executing an internal resistance-based determination unit to determine an internal resistance of the battery based on a terminal current generated in the battery during driving of the electric vehicle to determine a second SoH of the battery based on the internal resistance,
determining a residual battery value of the battery based on the first battery value and a second battery value, the first battery value determined based on the first SoH and the second SoH and the second battery value determined based on the electric vehicle data comprising vehicle identification data, charging history data, battery usage environment data, and vehicle driving data,
determining at least one replacement timing of the battery based on the battery state data,
determining at least one replacement place of the target battery,
providing a plurality of sets of battery replacement recommendations to a user, at least one set of the plurality of sets recommending the at least one replacement timing and the at least one replacement place of the target battery to the user, at least one of the sets of the plurality of sets being based on routine travel times on a route the user routinely travels in the electric vehicle, and
receiving a selection of the battery replacement recommendation from the user among the plurality of sets of recommendations;
replacing the battery with a fully charged battery at the at least one replacement place using a replacement service for a second-type battery using a change in an initial battery value based on the residual battery value.
2 . The method of claim 1 , wherein the first SoH represents information on a charge amount maintained as compared to an initial charge amount of the battery.
3 . The method of claim 1 , wherein the second SoH is determined based on a battery equivalent circuit model.
4 . The method of claim 3 , wherein the internal resistance is estimated using a relationship between a terminal current and a terminal voltage during generation of a discharge current during driving of the electric vehicle.
5 . The method of claim 4 , wherein:
the first battery value is based on a final SoH determined using the first SoH and the second SoH,
the final SoH is determined by assigning different weights to the first SoH and the second SoH.
6 . The method of claim 1 , wherein the electric vehicle data including data regarding a destination to which the electric vehicle intends to move, a speed of the electric vehicle, and a driving environment of the electric vehicle.
7 . The method of claim 6 , wherein the step of replacing the battery includes providing a first-type battery replacement service and a second-type battery replacement service, the first-type battery replacement service being a replacement service for a first-type battery in which a user's initial battery value is not considered and the second-type battery replacement service is a replacement service for the second-type battery.
