Battery backup systems and methods for vehicle phone systems

摘要

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.

主权项

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.
