ABSTRACT:
BACKGROUND OF THE INVENTION
Another object of this invention is to provide a means of remotely indicating battery condition.
Another object of the invention is to provide a bi-directional communication means for transferring data and instructions.
PRIOR ART
Some lead-acid battery manufacturers use visible warning indicators to show a battery may be discharged or defective. The indicators are only responsive to one cell in the battery and the viewer must be near the battery. Many times the battery is in an in-accessible location, such as under an automobile seat or in a remotely located battery room. The present invention provides for several novel methods to convey battery condition information to a suitable convenient location.
SUMMARY OF THE INVENTION
Additional embodiments of the present invention provide methods for communicating the battery condition. A failure indicator may be located remotely from the battery monitor in proximity of an observer. Information representing the battery condition may be communicated by simple serial data interfaces, or a variety of information networks known to those in the art such as SAE J-1739, SAE J-1750 or J-1850.
