20. A method of monitoring at least one battery, comprising:
-
generating an AC current and superimposing the AC current on a float voltage of the at least one battery, the AC current being generated by varying the battery voltage at a frequency of about 20 Hz, an amplitude of the voltage variation being configured to be smaller than a difference between the float voltage and an open cell voltage (OCV) of the at least one battery;
measuring an analog signal related to the at least one battery, the analog signal representing at least one a voltage, a current, and a temperature;
converting the analog signal to a digital signal; and
wirelessly communicating the digital signal via a Zigbee communication protocol to an external handheld device;
wherein the steps of measuring, converting, and communicating are performed by an arrangement that is at least one of embedded in the at least one battery and attached to the at least one battery.
