Method and arrangement for a controlling strategy for electronic components in a hybrid electric vehicle

Abstract

A method for controlling a cooling arrangement for electronic components in a hybrid electric vehicle is disclosed. The method includes arranging an electronics cooling loop aboard a hybrid electric vehicle in which a DC to DC converter, DC to AC inverter, and an electronics radiator are placed in fluid communication, one with the others, for cooling the DC to DC converter and the DC to AC inverter; sensing a temperature condition in the electronics cooling loop; and discontinuing operation of the DC to DC converter when a predetermined upper threshold temperature condition is sensed in the electronics cooling loop. A voltage condition of a 12 volt battery may also be sensed, and operation of the DC to DC converter may be resumed when the voltage condition sensed falls below a predetermined lower voltage limit.

Dependencies are inferred from the claim text.
