Techniques for controlling energy consumption and enhancing systemic efficiency through management of thermal devices for electrified vehicles

A control and thermal management method for an electrified vehicle, the method comprising:

• providing a set of thermal systems and a supervisory controller connected to each other via a local interconnect (LIN) bus, wherein each thermal system is powered by a low voltage battery of the electrified vehicle and is configured to regulate a temperature of a thermal loop of the electrified vehicle;
• in response to a valid wakeup request, transmitting, by the supervisory controller and via the LIN bus, timing instructions for operation of the set of thermal systems, thereby avoiding unnecessary energy drainage from the low voltage battery;
• in response to an ignition-off request, commanding, by the supervisory controller and via the LIN bus, a request for the set of thermal systems to complete their existing functions within a calibratable period;
• and
• in response to a function completion confirmation from the set of thermal systems, commanding, by the supervisory controller, the LIN bus and the set of thermal systems to shutdown, thereby avoiding a communication delay or a malfunction that could result in the set of thermal systems remaining active after the LIN bus is shutdown.
