Asynchronous multi-purpose battery interface
Abstract:
A method and apparatus for controlling a battery operating mode. The method includes connecting an electronic processor to a first electrical contact of a battery interface via a switch; generating, with the electronic processor, an initialization pulse for a signal demultiplexer of a battery; transmitting the initialization pulse to the signal demultiplexer; generating, with the electronic processor, a data word indicating a desired operating mode; transmitting the data word to the signal demultiplexer; generating, with the signal demultiplexer, a signal to electrically connect a first battery switch to the first electrical contact, the first battery switch selected based on the data word; receiving, with an analog to digital converter of the electrical device, a signal indicating the operating mode voltage; and verifying, with the electronic processor, a correct operating mode based on the operating mode voltage.
