Double Layer Battery Thermal Cycling Test Chamber
| 1.1 Cooling System | ||
| 1 | The refrigerating system uses environmentally friendly refrigerant R404a (R449a as option) and R23. Adopting binary low temperature circuit system design, it is convenient to use different compressors for work in different temperature regions. | |
| 2 | Temperature and humidity control using P.I.D + S.S.R system coordinated control with the same channel. It has the function of automatic calculation, which can immediately modify the temperature change conditions to make the temperature control more accurate and stable. | |
| 3 | High-precision controllers of temperature. The relative temperature performance is accurately set and displayed with a resolution of 0.1 ℃. | |
| 1.2 Temperature System | ||
| 1 | Temperature system using Nickel-chromium alloy high-speed heating electric wire; | |
| 2 | High temperature system is completely independent; | |
| 3 | Contains four temperature sensors to detect the surface temperature of the battery and display it on the controller | |
| 1.3 Control System | ||
| Temp. Sensor | High precision PT100 Platinum resistance | |
| Controller | Weintek | |
| Display Function | a. Temp. Setting (SV) Practical (PV) value can be displayed directly b. Display numbers, paragraphs, remaining time and cycles, running time c. Program editing and graphic curve display, d. Fixed or program operation status display, |
|
| Interface | a. RS-232 or R485 port design b. Connected to computer c. Monitor and remote control by computer and Ethernet |
|
| 1.4 Protection System | ||
| 1 | Protection for Electrical leakage | |
| 2 | Over-temperature | |

| Testing hole | Diameter 150mm, there are 2 holes for cable routing for each chamber | |
| Evaporator | Finned tube heat exchanger | |
| Dry filter | Absorb the residual moisture and acidic substances in the refrigerant of the refrigeration system, and filter out solid particles, copper shavings, etc. in the system to protect the normal operation of the expansion valve and capillary tube, and prevent ice blocking and dirty blocking. | |
| Door handle | Non-reaction, explosion-proof door handle, easy to operate, safe and reliable | |
| Insulation | 100mm polyurethane rigid foam and 100mm high density glass fiber cotton | |
| Insulation system | Filling the insulation area with ultra-fine glass fiber; Machine connection parts are made of non-metal resistant high and low temperature materials, which effectively reduces the temperature conduction; Door seal is made of refined silicone rubber, which is more reliable seal; |
|
| Observation window | Double-layer vacuum-strengthened glass; Heat-resistant defrosting on the inside with adhesive sheet conductive film, which can clearly observe inner chamber. |

| 2.5Test Standard | ||
| 1 | IEC6008-2-1 Cold | |
| 2 | IEC6008-2-2 Dry Heat | |
| 3 | IEC60068-2-38 Damp Heat, Cyclic | |
| SAFETY EQUIPMENT | SPECIFICATION |
| Status indicator | The tower light has 3 signal levels (white, green, and red) to quickly alert the operator of any abnormal conditions |
| Electrical door lock | The test space door is locked via an electrical door lock during automatic and manual tests. In automatic mode the complete testing system can be switched off during a program interruption, in order to allow the unlocking of the test space door. |
| Reversible pressure release flap | This device is installed on the top of chamber. |
| Mechanical door lock | Except reversible pressure release flap, two fasteners which mechanically hold the door closed are attached to the test space door |
| Sealing plug | One 50mm or 100mm diameter cable port on left with flexible silicone plug |
| Fire detection via CO2 gas measuring |
The system is equipped with a control unit, an alarm panel, an emergency button, a thermostat with dedicated temperature probe and a system with a CO2 cylinder. The CO2 discharge is activated by exceeding a temperature threshold (settable by the user) measured by a dedicated PT100 or by exceeding the CO2 threshold inside the chamber. The detection system, provided with its own power supply, activates the CO2 in the chamber. The CO2 bottle is empty, gas filled by user. |
