Battery Safety Testing

Battery testing
by cetecom advanced

cetecom advanced supports battery and automotive manufacturers in the safety qualification of high performance Li-ion battery systems. The safety of lithium-ion batteries, especially for application in electric vehicles and energy storage systems, is very important. Especially the high energy density due to the chemical elements used as well as the exceptionally high electrical charge must be controlled even in extreme situations to avoid hazards. Our battery safety testing services include a wide array of qualification procedures, which enables us to provide our customers with the necessary certifications for their (Li-ion) batteries.

The expertise and extensive testing capabilities of our battery testing labs ensure that all regulatory requirements are met.

Environmental & Endurance Testing

We have various accreditations for environmental and endurance testing and offer a wide variety of tests and test contents:

  • Mechanical stress
    • shock
    • crash test bench
    • vibration (if required under different climatic conditions incl. electrical load)
  • Electrical stress
    • cyclisation
    • BMS functionality
  • Climatical testing
    • cold
    • heat
    • temperature change
    • humidity
    • corrosion
  • Artificial ageing
  • EMC – electromagnetic compatibility of the battery management system (BMS)
  • LVD – electrical safety for high-voltage devices in battery systems
  • Immersion/Flooding
  • Recording system for displaying the test result
    (high-speed camera, infrared video camera, data recording)

UN Transport Test UN 38.3

Since 2003, special rules have been in place to ensure the safe transportation of Li-ion batteries.
These UN transport regulations have been issued by the UN and apply to transport by land, sea and air.

All batteries falling under UN 3480 have to undergo a UN Transport Test UN 38.3.

cetecom advanced verifies the safety of these batteries according to ST-SG-AC.10-11, 38.3.

Abuse / Safety tests

With a test facility for Abuse Tests on large batteries that is almost unique in Europe,
cetecom advanced has further strengthened its testing capabilities for the automotive industry.

Our Abuse & Safety tests include various test scenarios:

  • Electrical Testing
    • overcharge
    • discharge
    • short circuit
  • Mechanical Testing
    • crush test
    • nail penetration
    • tests on the crash test bench
  • Propagation
    • thermal
    • electrical

Testing for battery manufacturers

The development of advanced lithium-ion battery packs requires expertise and experience to balance the required system load with the required reliability and safety. cetecom advanced supports assemblers of battery packs in the development of safe battery systems, no matter in which application area.

We offer accredited testing according to the following international standards:

  • UN Transport Tests
    see chapter UN Transport Test
  • DIN EN IEC 62133-1
    Safety requirements for portable sealed secondary cells for use in portable equipment, nickel system
  • DIN EN IEC 62133-2
    Safety requirements for portable sealed secondary cells for use in portable equipment, lithium system
  • DIN EN IEC 62619
    Accumulators and batteries with alkaline or other non-acid electrolytes – Safety requirements for lithium accumulators and batteries for use in industrial applications
  • DIN EN IEC 63056
    Cells for use in energy storage systems
  • DIN EN IEC 63057
    Safety requirements for secondary lithium batteries for use in road vehicles other than propulsion systems
  • DIN EN 50604
    Secondary batteries for light electric vehicles
  • VDE-AR-E 2510-50
    Stationary energy storage systems with lithium batteries -Safety requirements

Other standards are possible upon customer request.

Tests according to ECE ECE R100 and ECE R136

ECE regulations generally refer to a set of internationally agreed general technical guidelines for both motor vehicles and their parts and equipment. Both regulations represent uniform rules with respect to battery-powered vehicles.

In its testing center for high performance battery systems, cetecom advanced is able to perform the different test cases:

  • vibration tests
  • thermal shock
  • mechanical shock
  • mechanical integrity
  • fire resistance
  • external short circuit
  • overcharge protection
  • discharge protection
  • overtemperature
  • overcurrent

We also offer propagation tests to prove chapter 6.15. We are designated by the KBA (Kraftfahrt-Bundesamt – German Federal Motor Transport Authority) as a technical service for ECE R100 and ECE R136. In our modern equipped battery test center we perform the described tests for you and support you in the handling of the KBA approval/homologation.
