Abstract

The electronic battery voltage monitoring circuit, is used to measure and evaluate the critical voltage. It is used mainly on car batteries, which are particularly sensitive to these limiting voltages. The circuit consists of an integrated window discriminator module(1) linked to the positive terminal of the battery via three LEDS (2, 3, 4). The diodes have a common load resistor (5). There is a logic circuit between the common terminal of the dioes and the other battery terminal. The reference voltage of the battery is adjusted via a potential divider with a variable resistor (6).
