Study on integrated thermal management system for extended range electric vehicles

Abstract

This article presents the design of an integrated thermal management system for extended range electric vehicles. By coupling the air conditioning and battery cooling circuits, the system integrates a motor cooling system and utilizes waste heat recovery from the motor and engine. Simulation based on AMESim platform shows that the intelligent hybrid cooling strategy can cool the passenger compartment and battery to the target temperature within 160s and 800s respectively at a high temperature of 40 ℃, with a system energy efficiency (COP) of 2.3, which is 43.8% higher than traditional systems; At a low temperature of -10 ℃, the motor waste heat recovery can provide heat to the passenger compartment within 800 seconds, and the engine waste heat recovery can provide heat to the passenger compartment and assist in cold start of the battery within 500 seconds. This system effectively improves the thermal management performance and energy utilization efficiency of the entire vehicle.
