In at least some implementations, a discharge circuit for an electric vehicle, includes a link capacitor, a resistive load, a discharge switch coupled to the link capacitor and to the resistive load so that the link capacitor is coupled to the resistive load when the discharge switch is closed to enable discharge of the link capacitor, and a discharge interrupt assembly. The discharge interrupt assembly has a sensing resistor connected in series with the resistive load, and a temperature circuit. The temperature circuit has an input connected to the sensing resistor and an output, and the discharge interrupt circuit is responsive to a voltage at the output of the temperature circuit to open the discharge switch when the voltage from the temperature circuit is higher than a threshold.
