Drive In and Walk In Battery Test Chambers

Our Drive In and Walk In Battery 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. Weiss Technik can help you be on the safe side with expertise in Electric and Hybrid vehicles environmental test chambers.

  • LEEF™ (Leading Energy Efficiency Footprint) technology is a high-efficiency refrigeration system that provides unmatched performance; it features optimal temperature and humidity control accuracy for precise testing results, faster ramp rates, and up to 40% energy savings.
  • The innovative WEBSeason® user interface allows you to program, control and monitor your tests at any time and anywhere – even from your tablet or smartphone

Specifications

Our test chambers are designed to meet a variety of test standards for safe and reliable testing. To assure this safety in your laboratory during tests with lithium batteries in a temperature- or humidity test chamber, we offer safety features, which are adjusted to the specific EUCAR Hazard Level. Of course, the safety equipment can be adapted individually, according to customer specifications. Please contact us for more detailed information.

Hazard Severity Level Description Classification Criteria and Effect
0 No Effect No effect. No loss of functionality
1 Passive Protection Activated No defect; no leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway. Cell reversibly damaged. Repair of protection device needed.
2 Defect/Damage No leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway. Cell irreversibly damaged. Repair needed.
3 Minor Leakage No venting, fire, or flame*; no rupture; no explosion. Weight loss
4 Major Leakage/ Venting No fire or flame; no rupture; no explosion. Weight loss ≥50% of electrolyte weight (electrolyte = solvent + salt).
5 Fire or Flame No rupture; no explosion (i.e., no flying parts).
6 Rupture No explosion, but flying parts of the active mass
7 Explosion Explosion (i.e., disintegration of the cell).

 

Safety in the laboratory and protection of the staff

During the temperature tests, overchargings or malfunctions of the batteries may occur. This can lead to the destruction of the batteries.

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.

To assure this safety in your laboratory during tests with lithium batteries in a temperature- or climatic test chamber, we can offer safety devices, which are adjusted to the EUCAR Hazard Level at an optimum. Of course, the safety equipment can be adapted individually, according to customer specifications. Please contact us for more detailed information
