Lithium battery high and low temperature test chamber standard models and parameters: Lithium-resistant high and low temperature testing machine features Lithium battery high and low temperature test box control system Lithium battery high and low temperature cycle test box is used by Kewen elite technical team independently developed KW-890 controller. Seven-inch true-color LED LCD smart programmable touch instrument, comes with USB and RS232C communication interface, replacing the old paperless recorder, through the USB interface directly high and low temperature aging test data easily import and export. Real-time history curve true color high-definition display, can be directly printed by computer, lithium battery high-low temperature cycle test box test report is real and clear, real-time control. The control system has the following ten major advantages:
PET Car Color Change Film with clear PET liner in high quality likes casting vinyl; and highlight gloss finish and strong imported glue;
PET Liner Gloss Metallic Auto Vinyl Wraps are made with high-quality film materials and a unique design that makes them more elastic, glossy, and solid.
installation tips:
PET liner car film is more diffcult to install than paper liner, the back glue is very sticky. Suggest Spay PET coating liquid to the towel and wipe first, or Mixed the blue liquid glass water +Alcohol 1:1 to reduce the viscosity of low glue. Spray to flat areas, except for curved and cornern.

1. Warming up, cooling down, and completely independent of the system can increase the efficiency, lower the test cost, increase the life span, and reduce the failure rate.
2. The temperature control adopts the all-imported touch-button instrument and the operation setting is simple.
3. After the data and test conditions are input, the controller has a lock function to avoid human touch and change the temperature value.
4. It has the function of PID auto-calculation and can immediately correct the temperature change condition to make the temperature control more accurate and stable.
5, optional printer 1, refrigerator using the French original "Taikang" closed compressor.
6. The refrigeration system uses a unit or binary cold circuit system design.
7. Adopt multi-blade air blower for strong air circulation to avoid any dead angle and make the temperature distribution in the test area even.
8. The air circulation and return air return design, wind pressure and wind speed all meet the test standards, and it can make the instant temperature of the door open to stabilize quickly.
9. The refrigeration system adopts a new refrigerant demand algorithm, which can reasonably and effectively use the cooling capacity, effectively reduce the consumption of heat and cold, thereby achieving stable control and energy-saving effects, saving more than 30% year-on-year.
