1. A battery backup system for use with vehicle telematics electronics, comprising:
- a phone module configured for operation by the vehicle telematics electronics;
a battery module configured to provide power to the phone module; and
a circuit configured to determine that backup power is needed and to cause the battery module to provide the backup power to the phone module for initiating a transmission via the phone module without providing operating power to the vehicle telematics electronics,wherein the battery module provides a low voltage output that meets a minimum power requirement of the phone module and does not meet a minimum power requirement of the vehicle telematics electronics,and wherein the circuit determines that backup power is needed in response to;
(a) a determination of a loss of primary power, and(b) at least one of a collision detect signal, an airbag deployment signal, or an automatic collision notification signal.

Abstract
A battery backup system for use with vehicle telematics electronics includes a phone module configured for operation by the vehicle telematics electronics. The system further includes a battery module configured to provide power to the phone module and a circuit configured to determine that backup power is needed. The circuit causes the battery module to provide the backup power to the phone module for completing a transmission via the phone module. The battery module can provide the backup power to the phone module without providing operating power to the vehicle telematics electronics.

11. A method for providing battery backup power to a phone module in a vehicle having telematics electronics that are normally powered by a vehicle power system, comprising:
-
determining that an ignition status is on; determining that backup power is needed at a backup circuit; and using the backup circuit to cause a battery backup module to provide backup power to the phone module for initiating a transmission via the phone module based on the determination that the ignition status is on and that backup power is needed at the backup circuit without providing operating power to the vehicle telematics electronics, wherein determining that backup power is needed includes; (a) determining a loss of primary power, and (b) determining that at least one of a collision detect signal, an airbag deployment signal, or an automatic collision notification signal has been received. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A battery backup system for use with vehicle telematics electronics, comprising:
-
a phone module configured for operation by the vehicle telematics electronics; a battery module configured to provide power to the phone module; a location system for determining a location of a vehicle, wherein the location system is configured to provide location data to the phone module; a circuit configured to determine that backup power is needed; and means for causing the battery module to provide backup power to the phone module in response to the determination that backup power is needed, the backup power for providing operating power to the phone module without providing operating power to the vehicle telematics electronics, wherein the phone module is configured to periodically store the location data from the location system in a location memory of the phone module, and wherein the circuit determines that backup power is needed in response to; (a) a determination of a loss of primary power, and (b) at least one of a collision detect signal, an airbag deployment signal, or an automatic collision notification signal. - View Dependent Claims (20)
