Commercial Vehicle Water-cooled Unit

Battery Thermal Management System (BTMS)

Operating Principle of Water-cooled Units

Water-cooled units utilize coolant as the cooling medium, which absorbs heat from the battery through circulation. Core components include the compressor, evaporator, condenser, expansion valve, and plate heat exchanger. The cooling effect is adjusted by altering the temperature and flow rate of the coolant.

Application Scenarios of Water-cooled Units

These units find applications in electric buses, electric construction machinery, electric trucks, electric heavy-duty trucks, energy storage power stations, etc.

Development History of Water-cooled Units

• Evolution from simple radiators to modern intelligent control systems.
• Continuous innovation in materials and technologies to enhance cooling efficiency.
• Energy-saving and environmental protection standards driving technological advancements in water-cooled units.

Significance of Water-cooled Units in Commercial Vehicles

Water-cooled units ensure that batteries, motors, and electronic control systems operate within normal temperature ranges. This not only extends battery life but also improves the operational efficiency of vehicles.
