04052717 is referenced by 35 patents and cites 1 patents.

A battery condition monitoring device which senses battery terminal voltage and creates a function thereof and tests that function against predetermined criteria and determines battery condition as a result of such tests. Furthermore, the invention operates on the transient of the battery terminal voltage existant immediately upon the loading of the battery. The test is performed on the slope of the terminal voltage transient and a function of that transient during a test period is created, analyzed and evaluated against reference levels.
