Security Tests for Lithium-Ion Batteries

The safety of lithium-ion batteries, especially for use in electric vehicles is very important. In particular, the high energy density in form of chemical elements and the usually high electric charge must be controlled in electric vehicles, even in extreme situations in order to avoid hazards for road users. One example for hazards which must be absolutely avoided is a lithium-ion battery firing or exploding due to a damage from a car accident. In stationary use, however, an energy storage has to face other risks such as flooding or the loss of air conditioning.

In our laboratory, we support our customers in the development of safer battery systems, no matter which application area.

For doing so, all safety-related disciplines and events which can occur during the use of lithium-ion batteries are available for testing at CETECOM:

• Mechanical Stress
  • Nail-Penetration
  • Crush-tests
  • Crash-Test bench
  • Vibration
  • Optional under various climatic conditions
• Electrical Stress
  • Overcharge
  • Short Circuit
• Climatical Stress
• Artificial Aging
• EMC - Elektromagnetische Compatibility of the Battery Management System (BMS)
• LVD - Electrical Safety for High Voltage devices in Battery Systems
• Immersion / Flooding
