System Architecture Evolution and Technological Trends
With the increase in battery energy density and the widespread adoption of fast charging technology, the heat generated by battery packs has increased significantly, posing new challenges to traditional thermal management solutions. Future systems will increasingly integrate advanced technologies such as phase change materials (PCM) and gas jet heat pumps (GIHP) to improve temperature control efficiency in extreme environments.
Simultaneously, the integration of the thermal management system with the vehicle's communication network is becoming increasingly tight. The Battery Management System (BMS) can send control commands to the thermal management system via the CAN bus to achieve precise temperature regulation and obtain real-time system diagnostic information, improving fault warning and maintenance efficiency.
In the commercial vehicle sector, to adapt to vehicle spatial layout and operating characteristics, battery pack cooling systems often adopt a modular and distributed design. For example, rooftop cooling systems can independently arrange heat dissipation units on the roof, saving interior space and facilitating hot air exhaust, making them particularly suitable for electric buses and refrigerated logistics vehicles.
Challenges and Prospects
Despite continuous advancements in electric vehicle thermal management system technology, several challenges remain: high system design and integration complexity, susceptibility to pipe aging and leakage, potential corrosion of flow channels by long-term coolant use, high maintenance costs, and the need to strictly comply with increasingly stringent safety and energy efficiency standards. In the future, thermal management systems will develop towards higher energy efficiency, stronger environmental adaptability, and lower life cycle costs, and will be more deeply integrated with vehicle energy management and intelligent connectivity, providing key technological support for the widespread adoption of electric vehicles.
