Abstract
A power system for a digital license plate includes a sensor, storage memory, and a battery status monitor operable only during operation of the digital license plate. The battery status monitor includes an analog to digital converter (ADC) connected to a battery to provide status data to a processor in the digital license plate, with status data being stored in the storage memory. A determination of battery lifetime being made at least in part using the status data and input from the sensor. In one embodiment status data can include external temperature.
Claims17
A power system for a digital license plate comprising:
- a sensor;
- storage memory;
- and
- a battery status monitor operable only during operation of the digital license plate, the battery status monitor comprising an analog to digital converter (ADC) connected to a battery to provide status data to a processor in the digital license plate, with status data being stored in the storage memory, and with a determination of battery lifetime being made at least in part using the status data and input from the sensor.
A method for measuring battery health in a digital license plate, comprising the steps of
- in response to a sensor triggered operational state that activates the digital license plate;
- waking a processor, memory, and ADC connection to a battery;
- reading battery voltage through the ADC connection and storing the result in memory;
- and
- using the processor to determine battery health at least in part using the read battery voltage.
