Application:
This testing machine is mainly used for battery overcharge and overdischarge, the battery is placed in the explosion-proof box, the external charge and discharge tester to prevent battery short circuit resulting in excessive current change caused by explosion, to avoid battery flying debris to protect the operator and equipment, is the first choice for power battery research, testing, testing equipment, the test box can be customized according to the test needs.
Principle:
The air room space is heated. The test box is equipped with an air room, circulating air duct, heating device and circulating fan, and the air deflector and diffuser are installed on the top. The temperature controller sends instructions according to the set temperature and the transmission signal of the temperature sensor in the test box, controls the output of the heater through the calculus time and SSR control module, and the circulating air evenly blows out from the top through the test space and then recovers from the bottom to form a closed-loop control mode, so as to achieve the purpose of long-term stable operation.
Parameters:
1. Inner box size: W500×H750×D600 mm (with 2 stainless steel mesh laminates)
2. outer box size: W1000×H1600×D1000 mm (subject to the actual)
3. inner wall material: SUS304 stainless steel, plate thickness ≥2mm;
4. outer wall material: cold-rolled steel plate painting treatment, plate thickness ≥1.2mm;
5. insulation material: insulation medium is glass fiber cotton, insulation material thickness: 100 mm
6. box door: single door, the inner box door is made of stainless steel, and add silicone sealing strip, the door is open with an observation window; The door is connected with the box by a strong hinge, anti-explosion handle door lock;
7. temperature range: RT+15℃ ~ 150℃
8. temperature deviation: ±2℃
9. temperature fluctuation: ±0.5℃
10. temperature resolution: 0.1℃
11. heating rate: RT→150℃ average > 3℃/min
12. observation window: located on the front of the box, easy to observe the status of the test product in the test box;
13. Box body: pressure relief port is opened on the back side.
14. power source: AC220V 50HZ 6KW
