ABSTRACT:
The inverting and non-inverting input terminals of a voltage comparator are connected across the cables of a battery charging system through R-C circuits having substantially different time constants. When the cables are disconnected from a battery being charged, the rapid increase in output voltage of the charging system momentarily reverses the relative values of voltage at the comparator inputs and produces a control signal which automatically deenergizes the battery charging system.
