Abstract
A battery monitoring device attached to a vehicle battery includes a battery voltage sensor, motion sensor, location determination module, memory device, wireless modem, and controller. The battery voltage sensor senses the voltage level of the vehicle battery, the motion sensor senses movement of the battery monitoring device, and the location determination module determines the location of the battery monitoring device. The memory device stores a unique identification number associated with the battery monitoring device. Upon detection of an event as indicated by the battery voltage signal or the motion signal or the location information, the wireless modem transmits an alert message that includes the unique identification number and information regarding the event. The components of the device may be encapsulated in a potting compound within a cavity on the battery housing, or they may be enclosed in a housing that is separable from the battery housing.
