CHARGE SOUND SYSTEM : System Description


SYSTEM DIAGRAM







SYSTEM DESCRIPTION

- The charge sound system is a function that notifies of the charge connector status and the charge acceptance status.
- The charge sound system operates when the power switch is OFF.
- The charge sound system consists of the following 2 types and operates through a link with the charging status indicator.
- Plug-in detection sound.
- Charge acceptance sound.

PLUG-IN DETECTION SOUND

- The plug-in detection sound notifies that the charge connector is engaged normally.
- During quick charge, the plug-in detection sound does not operate.
Operation Description
- The VCM outputs the charge pulse signal to the VSP control unit.
- The VSP control unit determines the plug-in detection sound using the charge pulse signal (2 pulses) from the VCM.
- When the VSP control unit inputs the charge pulse signal (2 pulses), the VSP speaker signal is outputs to the VSP speaker.
Operation Condition
The plug-in detection sound operates when all of the following conditions are met.






CHARGE ACCEPTANCE SOUND

The charge acceptance sound notifies that the charge is accepted.
Operation Description
- The VCM outputs the charge pulse signal to the VSP control unit.
- The VSP control unit determines the charge acceptance sound using the charge pulse signal (3 pulses) from the VCM.
- When the VSP control unit inputs the charge pulse signal (3 pulses), the VSP speaker signal is output to the
VSP speaker.
Operation Condition
The charge acceptance sound operates when all of the following conditions are met.





Signal Path
- The VSP control unit uses the signal shown below to judge the plug-in detection sound function and charge acceptance sound function, and it activates the plug-in detection sound and charge acceptance sound.





- When the VSP control unit judges that the plug-in detection sound and charge acceptance sound are necessary, it outputs the signal shown below.
