Product Description

Battery Thermal Management Unit
1. Product Introduction
With the rapid development of electric vehicles, the continuous upgrading of power equipment has increasingly higher requirements for battery performance and battery modularization. A series of problems caused by battery heat generation have become increasingly prominent. The quality of battery temperature control directly determines the performance and service life of the battery. Therefore, the battery thermal management system occupies a core position in electric vehicles. The product has a wide range of applications, including new energy buses, heavy - duty trucks such as mining trucks.The battery thermal management unit is an air - conditioning system composed of a compressor, condenser, throttling element, evaporator, water pump, expansion tank, PTC liquid heater and necessary control components, which is used to regulate the temperature of on - board batteries. The main purpose of the battery thermal management system is to keep the battery pack always working within an appropriate temperature range to maintain the optimal working state of the battery pack. Its main functions are:

• Monitoring: Accurately measure and monitor the temperature of the battery.
• Heat Dissipation: Effectively dissipate heat when the battery temperature is high to prevent thermal runaway accidents.
• Preheating: Preheat the battery when the temperature is low, raise the battery temperature, and ensure the charging and discharging performance and safety at low temperatures.
• Temperature Equalization: Reduce the temperature difference within the battery pack, suppress the formation of local hot spots, prevent the battery at high - temperature positions from decaying too quickly, and improve the overall service life of the battery pack.
