Method of Indicating the State of Charge of a Battery.
Abstract
The general object of this invention is to provide a simple and economic method of determining the state of charge of a battery. A more particular object of the invention is to provide such a method where the battery is one that shows a constant open circuit and/or load potential until the battery is nearly used up. A particular object of the invention is to provide such a method for a lithium battery. The method uses the operation of a LED clock, which is very inexpensive and can run off a tiny fraction of current supplied by the battery itself. For a particular battery and piece of equipment, one knows the expected battery capacity or lifetime and therefore is able to gauge when replacement is necessary. Patent applications. (JES)
