Abstract
A temperature-sensitive portion of the circuit of a voltage regulator of a vehicular battery charging system is located in or on the battery for simultaneously sensing the battery voltage and the battery temperature so as to provide through a single additional connection the necessary information to the remainder of a voltage regulator which is mounted in the vehicle generator. The temperature-sensitive portion of the voltage regulator components, which may be constituted by a single resistor, can be located in a housing in the connection clamp to the ungrounded terminal of the battery, in the filling cap of a battery cell or in a cavity in the battery case.
