Battery power source circuit

Abstract

Abstract PURPOSE:To discriminate exactly a degree of consumption of a battery by one piece unit, by switching successively plural batteries by a switching element, supplying them to a load side, and also displaying its switching state. CONSTITUTION:At first, an output voltage V of a battery 1A is supplied to a load side through a diode 2A. However, when the battery 1A is consumed and its output voltage V drops to a detecting level V1 of a detecting circuit 4, an output D is generated from the detecting circuit 4, and a counting output CTB is outputted from a ring counter 7. Subsequently, an SCR6B conducts, an output voltage V of a battery 1B is supplied to the load side, and also the counting outout CTB is displayed on a displaying circuit 5. In this way, each battery 1A-1N is switched successively whenever it drops to the level V1, and at the same time, which battery in its order is being used is displayed.
