Charging cue system for a vehicle

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.

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.
