THE TECH
Smart Technology
Smart Control for Liquid Cooling and Heating
Intelligent cooling and heating system is designed to maintain optimal operating temperatures for the entire system, ensuring stability and efficiency in any environment. When the ambient temperature reaches a pre-set threshold, the system automatically activates either cooling or heating mode.
This intelligent temperature regulation ensures that the system remains within a normal operating temperature range, enhancing reliability and longevity. Whether in extreme cold or heat, the system provides a robust solution for maintaining peak performance.
Fire safety
Battery Compartment Protection
Advanced fire safety measures are in place to effectively mitigate potential fire risks in the battery compartment.
