The charging cue system also includes an electronic control unit (ECU) that is communicatively coupled with the battery controller and the speaker system. The ECU includes data processing hardware that is configured with an audible cue application and memory hardware that stores charging parameters. The audible cue application includes an audible progress monitor that is configured as a function of the charging parameters and configured to project at least one cue at the speaker system in response to the battery data. ## Claims ### Claim 1 A charging cue system for a vehicle, the charging cue system comprising: a battery including a battery controller storing battery data; a charging port including a sensor, the sensor being configured to capture connection data at the charging port; a speaker system; and an electronic control unit (ECU) communicatively coupled with each of the battery controller, the charging port, and the speaker system, the ECU including data processing hardware configured with an audible cue application and memory hardware storing charging parameters based on the battery data and the connection data, the audible cue application (A) including an audible progress monitor having cue characteristics comprising at least one of volume, tone, pitch, and frequency and (B) configured to (i) alter one or more of the cue characteristics in response to one or more of the charging parameters and (ii) project distinct cues at the speaker system that correspond with at least two of a connection status, an authorization status, a charge status, a completion status, and an error status. ### Claim 2 (depends on 1) The charging cue system of claim 1, further including a proximity sensor coupled to a body of the vehicle and being configured to gather proximity data. ### Claim 3 (depends on 2) The charging cue system of claim 2, wherein the proximity sensor is communicatively coupled with the ECU and the audible cue application is configured to project the distinct cues in response to the proximity data and the connection status. ### Claim 4 (depends on 1) The charging cue system of claim 1, further including a user device in communication with the ECU and including a mobile wallet, the mobile wallet including the audible cue application. ### Claim 5 (depends on 4) The charging cue system of claim 4, wherein the charging parameters include a target charge level and the audible progress monitor is configured to issue the distinct cues in response to a charge status of the battery corresponding to the charge level. ### Claim 6 A charging cue system for a vehicle, the charging cue system comprising: a battery including a battery controller storing battery data; a speaker system; and an electronic control unit (ECU) communicatively coupled with the battery controller and the speaker system, the ECU including data processing hardware configured with an audible cue application and memory hardware storing charging parameters, the audible cue application (A) including an audible progress monitor having cue characteristics comprising at least one of volume, tone, pitch, and frequency and (B) configured to (i) alter one or more of the cue characteristics in response to one or more of the charging parameters and (ii) project distinct cues at the speaker system that correspond with at least two of a connection status, an authorization status, a charge status, a completion status, and an error status. ### Claim 7 (depends on 6) The charging cue system of claim 6, further including a proximity sensor coupled to a body of the vehicle and being configured to gather proximity data. ### Claim 8 (depends on 7) The charging cue system of claim 7, wherein the proximity sensor is communicatively coupled with the ECU and the audible cue application is configured to project the distinct cues in response to the proximity data and the connection status. ### Claim 9 (depends on 6) The charging cue system of claim 6, further including a user device in communication with the ECU and including a mobile wallet, the mobile wallet including the audible cue application. ### Claim 10 (depends on 9) The charging cue system of claim 9, wherein the charging parameters include a target charge level and the audible progress monitor is configured to issue the distinct cues in response to a charge status of the battery corresponding to the charge level. ### Claim 11 A computer-implemented method when executed by data processing hardware causes the data processing hardware to perform operations comprising: detecting, via a charging sensor, connection of a charger at a charging port of a vehicle; activating, via an electronic control unit (ECU), an audible cue application in response to the detected connection; executing, in response to the activated audible cue application, an audible progress monitor that includes cue characteristics comprising at least one of volume, tone, pitch, and frequency; receiving, at the ECU, battery data from a battery controller and connection data from the charging sensor; determining and storing, in memory hardware of the ECU, charging parameters based on the battery data and the connection data; issuing a connection cue of the executed audible progress monitor; monitoring, via the audible cue application, charging parameters of the vehicle; updating the audible progress monitor based on the charging parameters; and issuing a cue distinct from the connection cue and corresponding to at least one of an authorization status and a charge status. ### Claim 12 (depends on 11) The method of claim 11, wherein updating the audible progress monitor includes issuing at least one cue at one or more of a speaker system of the vehicle and a user device. ### Claim 13 (depends on 1) The charging cue system of claim 1, wherein, upon detection of an error in a connection between the vehicle and a charging station, the audible progress monitor is configured to issue a cue corresponding to the error status that is distinct from a cue corresponding to the connection status. ### Claim 14 (depends on 1) The charging cue system of claim 1, wherein the charging parameters include a target charge level of the battery that is less than a full charge. ### Claim 15 (depends on 1) The charging cue system of claim 1, wherein the speaker system includes at least one exterior speaker that is configured to project the distinct cues external to the vehicle. ### Claim 16 (depends on 6) The charging cue system of claim 6, wherein, upon detection of an error in a connection between the vehicle and a charging station, the audible progress monitor is configured to issue a cue corresponding to the error status that is distinct from a cue corresponding to the connection status. ### Claim 17 (depends on 6) The charging cue system of claim 6, wherein the charging parameters include a target charge level of the battery that is less than a full charge. ### Claim 18 (depends on 6) The charging cue system of claim 6, wherein the speaker system includes at least one exterior speaker that is configured to project the distinct cues external to the vehicle. ### Claim 19 (depends on 11) The method of claim 11, wherein updating the audible progress monitor includes altering at least one cue characteristic selected from volume, tone, pitch, and frequency in response to at least one of the charging parameters. ### Claim 20 (depends on 11) The method of claim 11, further comprising receiving, at the ECU, proximity data from a proximity sensor coupled to a body of the vehicle, wherein updating the audible progress monitor includes issuing at least one cue in response to the proximity data and the connection data.
