As the new energy vehicle (NEV) industry undergoes rapid iteration and its market penetration continues to rise, vehicle safety, range stability, and durability have become the core competitiveness of automakers. The NEV thermal management system is the core assembly that ensures the stable operation of the three-electric system (battery, motor, and electronic control) and prevents the risk of vehicle thermal runaway.

As the "temperature control heart" of new energy vehicles, the thermal management system encompasses core components such as water pumps, compressors, heat exchangers, electronic expansion valves, cooling pipes, and filters. It relies on precision pipe connections and sealing structures to achieve precise temperature control for the battery, motor, and electronic control. Strict assembly process precision is the key to ensuring system stability, vehicle safety, and range stability.

With the high-end and refined development of new energy vehicles, the industry has set extremely high standards for the assembly process of thermal management systems. Among these, core precision processes like bolt tightening, flange connections, and pipe joint assembly are the critical links that determine the system's sealing performance and operational reliability. Traditional manual tightening and semi-automatic assembly methods suffer from poor precision and inconsistent quality, failing to meet the current high-takt, high-precision, zero-defect production demands of automakers. This has become a core pain point restricting the quality upgrade of NEV thermal management systems and the improvement of overall vehicle yield rates.

I. Core Pain Points in NEV Thermal Management System Assembly

The core components of NEV thermal management systems, such as water pumps, compressors, heat exchangers, and filters, all demand extreme precision in bolt tightening and sealing consistency. Minor torque deviations or poor sealing during assembly can lead to serious vehicle quality issues like refrigerant leaks, cooling failure, and battery thermal runaway. This is a key challenge that current NEV manufacturers are focused on overcoming in production quality control.

First, insufficient tightening precision leads to prominent sealing failure risks. Traditional manual tightening relies entirely on operator experience, making torque and angle control highly random. Assembly defects such as insufficient tightening, false locking, thread stripping, or over-tightening that damages seals are common. For precision connection points like water pump housings, compressor mounting points, heat exchanger flanges, filter housings, and cooling pipe joints, even minor torque errors can directly cause refrigerant or coolant leaks. This leads to cooling failure and temperature control malfunction in the thermal management system, potentially triggering battery thermal runaway in extreme cases, posing a serious threat to NEV driving safety.

Second, poor production consistency fails to meet high-takt production demands. As current NEV production line takt times continue to decrease, manual assembly is inefficient, assembly precision is inconsistent, and yield rates are unstable, making it difficult to achieve standardized, high-volume production. Assembly variations across different workstations and batches lead to significant differences in vehicle thermal management performance, directly increasing after-sales failure rates and maintenance costs for automakers.

Finally, lack of data traceability leaves quality optimization unsupported. Traditional thermal management assembly methods often rely on manual records and paper filing. The data is fragmented, lacks authenticity, and has poor traceability, making it impossible to achieve full-process traceability of the tightening process. When assembly quality anomalies occur, the production, process, and quality control teams struggle to quickly identify the root cause, hindering process iteration and risk closure. This completely fails to meet the stringent MES data integration, intelligent production, and full lifecycle quality management standards of major automakers.
