Charge Disruption Monitoring and Notification System
First Claim
1. A method of notifying a party when operation of a battery pack charging system for an electric vehicle is disrupted, the method comprising the steps of:
- detecting initiation of a connection between said electric vehicle and a battery pack charging source, wherein said battery pack charging source is external to said electric vehicle;
monitoring operation of said battery pack charging system, wherein said step of monitoring operation of said battery pack charging system is performed after said connection between said electric vehicle and said battery pack charging source is detected;
issuing a command to a notification system to send a notification message to said party, wherein said step of issuing said command is performed by a system controller, and wherein said step of issuing said command is performed if a disruption in said operation of said battery pack charging system is detected;
evaluating a set of notification instructions stored in a memory coupled to said notification system upon receipt of said command to send said notification message; and
transmitting said notification message in accordance with said set of notification instructions upon receipt of said command to send said notification message.

Abstract
A system and method for notifying a designated party when an electric vehicle charging operation is unexpectedly disrupted is provided. The system monitors the connection between the electric vehicle and the external battery pack charging source, issues a command to a notification system to send a notification message to the designated party when an interruption is detected, and then issues the notification message in accordance with a set of notification instructions. The notification instructions may include one or more criteria for determining whether the disruption is authorized, thus not requiring the transmittal of the notification message. Criteria for accepting the change in battery pack charging status as authorized includes user/device proximity to the vehicle, achievement of a target battery pack SOC, and location of the vehicle within a safe zone.

28. A notification system for use with an electric vehicle, comprising:
-
an electric vehicle charging system coupleable to a power source, wherein said power source is external to said electric vehicle, and wherein said power source provides charging power for a battery pack mounted within said electric vehicle, said battery pack providing power for at least one drive train motor; a power source monitor mounted within said electric vehicle and configured to monitor a battery pack charging status, wherein said monitor detects when said power source is coupled to said electric vehicle charging system; a system controller coupled to said power source monitor, said system controller configured to receive a first status signal from said power source monitor when said power source is coupled to said electric vehicle charging system and to receive a second status signal from said power source monitor when a disruption in operation of said electric vehicle charging system power source is detected, wherein said system controller is configured to issue a notification command upon detection of a change in said battery pack charging status as evidenced by receipt of said second status signal after receipt of said first status signal, and wherein said system controller is configured to issue said notification command in accordance with a set of notification instructions; and a notification system coupled to said system controller, wherein said notification system is configured to transmit a notification message to a party externally located from said electric vehicle upon receipt of said notification command issued by said system controller. - View Dependent Claims (29, 30, 31)
