EV Battery Testing Chiller – Low Temperature Series

Temperature control in the testing process of new energy vehicle components.

The equipment can meet the requirements of direct cooling or direct heating for battery pack and electric vehicle testing. The device is mainly used for testing the cooling and heating capacity of the batteries. It can adopt a variable frequency compressor with adjustable output; variable frequency fan with adjustable speed and heat dissipation capacity. Combined with high precision temperature, pressure and flow sensors. It can also calculate heat transfer capacity in real time and automatically recover and add refrigerant. Can accommodate battery packs of different sizes.

The testing object is connected to a testing adapter; component cooling and heating test is conducted by ethylene glycol plus water mixture.

The test unit needs to go through a specific temperature range curve and record the temperature change. The temperature usually ranges from -40degC to 100degC (expandable up to 150degC)

Overview:

  • Working Temperature Range: -40degC to +150degC
  • Temperature/pressure/flow can be independently controlled
  • The temperature of antifreeze ranges from -40degC to +100degC (expandable to +150degC) with a very steep temperature gradient.
  • Different application related models like – One machine for two groups control; one machine for six groups control; Variable Frequency vortex compressor.
  • Variable frequency series models: Can adopt a variable frequency vortex compressor, the operating speed is automatically adjusted according to actual needs, providing the required cooling capacity. Compared with traditional fixed frequency compressors, it significantly reduces energy consumption and improves energy efficiency performance.
  • Constant power output function for both hot and cold.
  • LNEYA PLC control with 7-inch colour large screen and comprehensive multifunctional image display of important data information.
  • Relevant operational status data can be continuously monitored and visualized on the screen. Can independently control one to multiple flow channels where each group can be independently set.
