Battery tester
Abstract
An improved battery tester for determining the acceptability of a Lithium Sulfur Dioxide (LiSO2) storage battery at a given temperature and with one or more cells therein is discussed. The tester is generally made up of a first comparison circuit having a series of interconnected components, namely a comparator, first and second flip-flops, and an AND gate. A first resistor is parallel connected to the first comparison circuit. A second comparison circuit is also parallel connected to the first comparison circuit and is generally made up of a series interconnected components, namely a second resistor, a capacitor, a buffer, and a second comparator. A first switch is connected to the first resistor and a second switch is parallel connected to the second comparison circuit between the capacitor and the buffer. A logic control arrangement controls the operation of both switches, both comparators, and both flip-flops for testing a battery as to its start-up voltage and performance voltage characteristics all in a relatively short time period.
