Abstract
A telematics device having a voltage drop detector and a switchable voltage monitor is provided. The voltage drop detector detects a drop in the battery voltage characteristic of cranking and notifies a controller. In response, the controller switches on the switchable voltage monitor for obtaining the battery voltage. The telematics device may be used in vehicles or other equipment powered by engines.
