ISOLATION OF AUXILIARY ELECTRONICS BATTERY FROM STARTING BATTERY

摘要

A battery combiner may be used to electrically isolate first and second batteries during conditions in which a first battery required for a mechanical drive system may experience excessive power draw. The second battery may be used to provide a switched and/or continuous power source to a control system and/or other electrical devices for reliable operation, and the combiner may join the first and second batteries together such that both are electrically charged by a single alternator during conditions when it is safe.

主权项

1. An electrical system for an agricultural machine comprising:
a starter motor for starting the agricultural machine; an alternator for producing an electrical charge; a first battery in communication with the starter motor and the alternator; a second battery; a power distribution circuit for providing power to electrical loads of the agricultural machine; a switch, wherein the second battery is configured to provide a switched electrical power source to the power distribution circuit by going through the switch and a continuous electrical power source to the power distribution circuit by bypassing the switch; and a combiner in communication with the first and second batteries via first and second ports, respectively, wherein the combiner operates to connect the first and second batteries together for electrical charging by the alternator when the combiner senses a voltage at the first port above a threshold.
