Abstract:

A compact battery monitoring system for monitoring a vehicle battery in a vehicle having an engine is described. The compact battery monitoring system may comprise a housing, a processor positioned within the housing, one or more sensors operatively coupled with said processor, a data port, a wireless data transceiver, and rechargeable lithium ion battery. The data port may be configured to removeably couple with a second data port positioned outside the housing to provide an electrical connection between the one or more sensors and the vehicle battery, wherein said processor is configured to monitor a parameter of the vehicle battery using said one or more sensors, yielding a monitored battery parameter. The wireless data transceiver within the housing is configured to wirelessly communicate the monitored battery parameter to a remotely situated, portable user device using, for example, ultra high frequency radio waves. A display device may be positioned on the housing, including a plurality of light emitting diodes. The rechargeable lithium ion battery is configured to supply power needed to operate the processor and the wireless data transceiver. When the engine is running, the battery monitoring system draws a charging current from the vehicle battery to charge the lithium ion battery.
