Waste heat from engine exhaust and power electronics is reused through an integrated Rankine cycle that improves fuel efficiency without adding excess space or back pressure.

Continued heat-medium circulation after compressor shutdown cools the heat exchanger, lowering restart pressure and compressor power use.

A parallel electric and mechanical compressor setup switches by battery charge to keep cabin cooling on without risking hybrid vehicle start failure.

Classifying heater faults as restorable or not prevents repeated shutdown-restart cycles and restores vehicle heating only after the fault is cleared.

Dual interrupting stages stop heater current at rising temperatures and block re-energizing after control faults in EV and hybrid safety circuits.

Ambient and battery feedback control circulates coolant only when needed after EV shutdown to limit heat damage and reduce energy waste.

Two bimetal switches cut EV load current at rising temperatures and lock the supply line off to prevent unintended re-energization.
