Abstract

The present disclosure is a system and method for charging a high voltage battery of a hybrid automotive vehicle which contemporaneously provides a user with a visual display of diagnostic hybrid system information, including but not limited to, battery data and state of charge data through a user interface located internal a cabin of the vehicle. In other exemplary embodiments, the user interface is operable for providing the visual display while also providing access to other features of the vehicle to the user.

Claims

providing a plurality of operating modules operable for charging the high voltage battery and displaying battery diagnostic data to the user, said plurality of operating modules comprising a carrier sub-system electronically connected to a hybrid sub-system;

initiating a jump assist operation upon an attempt to start the vehicle;

determining whether the state of charge of the high voltage battery is greater than a defined minimum value, if the vehicle fails to start;

notifying the user that a charging function is required by displaying a message on an interface device;

initiating a charging function to charge the high voltage battery to a state of charge greater than the defined minimum value, if the state of charge is determined to be insufficient;

determining if the high voltage battery has been sufficiently charged;

notifying the user that the charging function is complete, if the state of charge is greater than the defined minimum value; and

terminating the jump assist operation,

wherein the state of charge is a ratio of the remaining capacity of the high voltage battery to the capacity of the high voltage battery in its fully charged state.

2. The method of claim 1, further comprising the steps of requiring the user to insert a key into the vehicle'"'"'s ignition and turning the key to a valid calibration position prior to determining the state of charge of the high voltage battery.

3. The method of claim 1, further comprising the step of periodically updating to the charging status of the high voltage battery by visually displaying charging status messages on the interface device, if the charging function is initiated.

4. The method of claim 1, further comprising the step of providing access to the user to vehicle devices and features during the charging function.

5. The method of claim 1, further comprising the step of requiring the user to connect an external energy source to the high voltage battery, if the state of charge is not greater than the defined minimum value.

6. The method of claim 5, further comprising the step of requiring the user to connect the external energy source to the high voltage battery in a defined time.

7. The method of claim 5, further comprising the step of aborting the charging function, if the external energy source is disconnected prior to the state of charge defined minimum value being reached.

8. The method of claim 7, further comprising the step of displaying a message to the user that the charging function was aborted.

9. The method of claim 8, further comprising the step of aborting the charging function, if the external energy source is not connected in the defined time.

10. The method of claim 9, further comprising the step of displaying a message to the user that the charging function was aborted.

11. The method of claim 4, wherein the vehicle devices and features are selected from the group consisting of an audio system, an air conditioning system, a heating system, a navigational system or a telephone system.

12. A user interface system for charging a high voltage battery of a hybrid vehicle and displaying hybrid system information to a user, comprising:
