Battery Pack Testing

Walk-in chamber for battery pack testing
For battery pack testing, SANWOOD can provide a custom-designed walk-in test chambers to test one or more battery packs.
On the basis of previous successful projects, SANWOOD can be customized according to the footprint, performance and other safety equipment to meet the most demanding customer requirements.

Environmental chambers are available from small benchtop chambers for testing small battery cells to large walk-in chambers for testing large battery packs. Temperatures range from -70°C to +150°C with an optional humidity range as low as 20% to 95%. Sizes are available from small benchtop units to large walk-in chamber.

Refrigeration System

Refrigeration System

  • In the process of cooling, from 150℃ we just turn on the first compressor, when the temperature down to 17℃, the second compressor will start to work.In this way, we not only can guarantee the cooling rate, but also energy saving, and extend the life of the compressor.
  • Compressors equipped with world famous brand such as Tecumseh (France made), Bitzer or GEA BOCK (Germany made).
  • Shock absorption and noise reduction process,slow down the vibration, protect the compressor.The new pipe bending technology: The bending process can minimize the connector point and make refrigerant flow more efficiently.
  • It applies Denmark DANFOSS and Japanese SAGLNOMIYA solenoid valves to improve the overall reliability of the equipment.
Electrical System

Electrical System

  • Equipped with internal power supply system, which is convenient for supplying power for testing samples, voltage is 220 Volts.
  • Our circuits are arranged in accordance with UK standards and are equipped with complete circuit diagrams. Each line has a unique code, which is clearly defined and easy to locate for troubleshooting.
  • Our chambers equipped with four pressure meter, customers can easily to check the pressure of the compressors.
  • We use electrical components of world famous brands, such as Schneider from France,Carlo Gavazzi from Switzerland,Mitsubishi from Japan,Rainbow from Korea.
