ABSTRACT:
A battery temperature compensation circuit for a DC/DC converter which is used to charge an auxiliary battery for an electric vehicle and including, among other things, a voltage sensitive resistance, such as a thermistor, coupled to a clamped voltage divider network which generates a resistance vs. temperature characteristic so as to control the DC/DC converter and provide an output voltage for charging the auxiliary battery which matches the voltage vs. temperature profile of the battery.
