Quiescent Current Detection in Automobiles

The recent advances in the Automobile Industry are the application of Electronics in the automobiles. The use of electronics in the automobiles is particularly concentrated on the improvement of performance parameters, comfort and safety conditions. The more complexity in circuits may cause failures. The energy perspective for the application of the electronics in automobiles is targeted on the battery as the battery is the only source of power in the idle condition. The common issue faced by the automobile industry is the energy loss in battery due the Quiescent current. The Quiescent current is the fact that represents the loading on the battery even when all loads are put off. The immediate effect of the Quiescent current is the ignition problem. The passive effects mainly include the loss in Ampere-Hours. This paper is dealt with the design of a conceptual circuit to detect the presence of faults and suitably indicate the failures in the electronic devices in the automobile by various perspectives.
