Abstract: The present invention is generally directed to a Sleep Manager Module (“SLM”). In one case, the present invention provides a stand-alone Sleep Manager Module. The Sleep Manager Module is capable of optimizing electric vehicle power consumption based on external temperature. It has one or more interfaces that are electrically connected to a microcontroller. The microcontroller is operably connected to memory, and the one or more interfaces is selected from a group of interfaces consisting of a fast charge connector, a level II Electric Vehicle Supply Equipment, and temperature/battery voltage sensors. The microcontroller is connected to a Vehicle Integration Manager through a Wake-Up line and Vehicle Communication Line.

Abstract: The present invention relates to a power circuit of an inverter for an electric vehicle, and, more specifically, to a power circuit supplying a high voltage direct current from a high voltage power source to a drive circuit for driving an AC motor for the electric vehicle. In one case, the present invention provides a method of detecting an IGBT short circuit failure or an IGBT open circuit failure during electric vehicle key ON and charging conditions. The method includes the steps of: a) receiving information that a vehicle key has been turned on; b) detecting whether there is an IGBT short circuit failure; c) initiating vehicle failure action if an IGBT short circuit failure is detected, but detecting whether there is an IGBT open circuit failure if IGBT short failure is not detected; d) determining that the vehicle is ready to drive if IGBT short failure was not detected.
