Feature 

JOEO® Battery Walk In Test Chambers are ideal for testing large EV battery packs. 
We understand that energy storage systems must be as safe as possible. External loads, caused by high or low temperatures, fast temperature changes, humidity, mechanical loads or corrosive influences, must be safe and not lead to failure or unintended reactions. JOEO® professional on the safe side with expertise in Electric and Hybrid vehicles climate chambers.

Safety in the laboratory and protection of the staff

1. During the temperature tests, overchargings or malfunctions of the batteries may occur. This can lead to the destruction of the batteries.
2. Increasing storage sizes cause increasing impacts of possible failures and potential risks during tests with lithium batteries. For this reason, safety in the laboratory, in particular the protection of the staff, during such tests has the highest priority.
3. To assure this safety in your laboratory during tests with lithium batteries in a temperature- or climatic test chamber, we can offer safety devices. Here, JOEO® following customers demand that the safety test chambers can be adapted individually,  Please feel free to inquiry from us online!

JOEO® Special add-on components can be supplemented for testing lithium-ion batteries

• Electrical door lock system
• Optic and acoustic alarm
• Pressure release flap
• N2 – Inertia Unit
• O2 – Measuring (additional option for N2 – Inertia)
• Fire detection system using a CO gas detection sensor
• Fire detection via temperature measurement (alternative)
• Flushing device using in case of fire
• Over pressure release via burst disc including reinforced inner container

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

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.
