Battery Safety Testing/ Battery Abuse testing

We at Resonate testing provide a wide range of testing services that will help to mitigate the risks associated Lithium battery powered devices, helping to ensure safety especially during transportation and customer use.

With increased use of lithium battery technology comes increased risk. Most lithium batteries manufactured today contain a flammable electrolyte and have an incredibly high energy density. The size of risks posed are generally a function of type, size, and chemistry.

Lithium batteries can also be prone to “thermal runaway”. This means is that if the internal circuitry is compromised, an increase in internal temperature can occur. At a certain temperature, the battery cells begin to vent hot gasses, and this can in turn increase the temperature in neighbouring cells. This temperature rise can propagate to other batteries or conductive materials nearby, thus causing the ‘Thermal runaway’ and potentially resulting in larger scale thermal events and sometimes ignition and fire.

As a result, large quantities of batteries can pose safety risk and therefore lithium batteries are considered hazardous materials / dangerous goods, and must be handled, stored and transported accordingly.

We are well used to testing with fire and batteries are no exception.  Our fully equipped, specialised fire test facility allows testing to various battery and battery packaging fire testing requirements.

As well as fire testing, there are many standard focused on abuse testing of batteries to ensure their safety and reliability on the field and in transit.  There are also specific standards based on where the battery is being used, whether in a vehicle, telecommunication device, child’s toy, etc. 

Some examples of standards and guidance materials are given below

  • IEC 62660-2 – Secondary lithium-ion cells for the propulsion of electric road vehicles – Part 2: Reliability and abuse testing
  • IEC 62660-3 – Secondary lithium-ion cells for the propulsion of electric road vehicles – Part 3: Safety requirements
  • IEC/EN/UL 60086-4 – the Standard for Safety for Primary Batteries – Part 4: Safety Of Lithium Batteries
  • IEC 62133-2 – Safety Testing for Lithium Ion Batteries
  • IEC/EN 62619 – Safety requirements for lithium ion cells, modules, and packs intend to stationary storage

Battery transport testing - UN 38.3 - Transportation of Dangerous Goods

Most lithium or lithium-ion batteries are safe when designed, manufactured and used properly. However, if they are comprised of low-quality materials, assembled incorrectly, used or recharged improperly, become damaged, or if they have design defects, they can pose a huge risk, particularly in transportation.

The finished lithium or lithium Ion battery has been identified as a Class 9 dangerous good during transport, as a result of a potential fire hazard. As such, they should be subjected to the range of electrical and mechanical tests included within UN 38.3 for the transportation of dangerous goods.  This standard applies to batteries being transported on their own or within devices.

UN 38.3 has been adopted by regulators and competent authorities around the world, making it a requirement for global market access.

The batteries must pass the tests without causing harm of involving disassembly, rupture of fire within 6 hours of the test, but the packs may perish during testing.

Packaging and Shipping of batteries

Shipping lithium batteries by sea

If shipping lithium batteries via sea freight, it is necessary to comply with the International Maritime Dangerous Goods (IMDG) Code. This document is updated every other year.

Lithium batteries and battery-powered equipment may be transported within the United States by vessel and by motor vehicle or rail either before or after being transported by vessel in accordance with the IMDG Code. We recommend that shippers consult the most recent edition of the IMDG Code, issued by the International Maritime Organization (IMO) for additional requirements. Publications and regulations issued by IMO can be found at: www.imo.org.

Shipping lithium batteries by road

If your lithium-ion batteries are being transported by lorry for transport within Europe, you must ensure that you comply with all of the requirements as outlined in the ADR 2017 manual. This is effectively the European Agreement that governs the shipping of lithium batteries by road / ground (and indeed that of any dangerous goods).

Shipping lithium batteries by rail

Transporting lithium batteries via train requires you to meet  a different set of specific guidelines for the transportation of dangerous goods. These regulations are detailed in the Carriage of Dangerous Goods by Rail (RID) guidelines.

Shipping lithium batteries by air

Shipping lithium batteries by air is the most complicated of all forms of transit, due to the increased risk (i.e. and aircraft accidents caused by fire are likely to be fatal). With damaged batteries being blamed for aircraft crashes in the past, the shipping of damaged or defective batteries is strictly forbidden.

When transporting lithium-ion batteries via air, the Dangerous Good Regulations (DGR) must be reviewed and met. These regulations are governed by the International Air Transport Association (IATA) and the International Civil Aviation Organization (ICAO).

The Federal Aviation Administration (FAA) Technical Center issued a series of test reports that characterised the hazards posed by lithium cells and batteries transported as cargo on aircraft and the effectiveness of certain aircraft fire suppression agents and packaging configurations in mitigating the associated risks. The FAA Technical Center testing shows that oxygen starvation through depressurisation in the case of cargo aircraft, common shipping containers (e.g., unit load devices), or aircraft fire suppression systems are not effective in containing or suppressing many potential lithium cell or battery fires. The tests showed a large variation in the fire hazard characteristics of the thermal runaway event. The characteristics depended on cell size, chemistry, construction, and orientation. As a result of the tests, it is recommended that each battery cell be evaluated on an individual basis dependent on its specific application and operating environment

FIRE HAZARD ANALYSIS FOR VARIOUS LITHIUM BATTERIES  https://www.fire.tc.faa.gov/pdf/TC-16-17.pdf

 

UN3480, UN3481, UN3090 and UN3091 classifications

The shipping of lithium batteries are effectively covered by 4 pieces of UN legislation, although there are numerous specifics within these can influence the exact process you need to take to ensure safe shipping (or at least minimise the risk as far as is possible).

Lithium batteries are now effectively classified as Class 9 material – termed “miscellaneous dangerous goods”.

The specific UN regulations covering the shipment of these batteries are as follows:

  • UN 3090, Lithium metal batteries (shipped by themselves)
  • UN 3480, Lithium ion batteries (shipped by themselves)
  • UN 3091, Lithium metal batteries contained in equipment or packed with equipment

UN 3481, Lithium ion batteries contained in equipment or packed with equipment
