Parasitic loads on a vehicular battery are evaluated based on an estimated reduction in the state of charge of the battery over the course of an engine-off state.

Telematics-based method and system of battery parasitic load validation for a vehicle fleet

A telematics method comprising the steps of: using a device in a vehicle, obtaining data including at least location and at least one device parameter during a time period between vehicle assembly and delivery to a retail customer; transmitting the data to a remote station for processing; conditionally communicating an alert for the vehicle responsive to the device parameter; and conditionally communicating, response to the device parameter and additional device parameters from additional vehicles, an alert for at least one of (a) a vehicle assembly plant, (b) a vehicle dealer, (c) a vehicle distribution center and (d) a vehicle logistical support center.
