Classification: CPC B  H | IPC B  H

Claim 15:
16. A discharge system for an electric vehicle, the discharge system comprising:
a step-down power converter configured to step down an input voltage to an output voltage, wherein the input voltage is higher than the output voltage and the step-down power converter is coupled to output the output voltage across supply rails;
discharge circuitry coupled between the supply rails;
a battery coupled across the supply rails;
electronics coupled to be supplied with power from the supply rails, wherein the electronics include an output terminal coupled to provide a drive discharge signal to the discharge circuitry, wherein the discharge circuitry is reversibly driveable by the drive discharge signal to allow current to flow between the supply rails; and
a decoupling diode disposed along a first of the supply rails and between a coupling of the discharge circuitry to the first of the supply rails and a coupling of the battery to the first of the supply rails.
