Features

Lightweight & Lower Cost

The battery thermal management system is integrated with the A/C, reducing cost by 30% and weight by 20%.

Integrated Management System

In a low-temperature environment, it can meet the needs of A/C heating and battery cooling at the same time.

More Intelligent

The dual-electronic expansion valve is used to precisely adjust the coupled PID refrigeration control to evenly distribute the cooling capacity in the vehicle and on the battery side.
