Battery technology and Lithium Ion (LI ion) batteries in particular, have undergone a massive and ongoing expansion, over a short space of time. Batteries now power countless items that support everyday life from portable computers, cordless tools, mobile telephones, watches and toys, to wheelchairs, bicycles and motor vehicles.
With multiple cell chemistries available, and differing performance and thermal management approaches, they offer an excellent combination of performance and efficiency.
Battery Performance testing
Resonate testing staff love to get involved in helping you with development and prototype testing of your batteries. Whether they are primary or secondary, cells, modules or batteries, Lithium-Ion or Lithium Metal and whatever their chemistry, we can provide bespoke performance and durability testing, helping to develop suitable test plans or provide comparisons between battery types. We can also carry out testing to any of the internationally recognised standards, including

Battery Safety Testing
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. Battery Safety testing can help provide due diligence and help to reduce these risks.
We at Resonate testing provide a wide range of battery safety testing services that will help to mitigate the risks associated Lithium battery powered devices, helping to ensure safety especially during transportation and customer use. These include thermal runaway propagation tests, nail penetration tests, impact, crush and overcharge, to name but a few.

One reason for this testing requirement is that Lithium batteries can 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, such as
-
AS6413/2 Performance based package standard for lithium batteries as cargo on aircraft - Direct Flame Test
-
AS6413/1 Performance based package standard for lithium batteries as cargo on aircraft - Oven Test
-
ASTM 1529-22 Effects of Large Hydrocarbon Pool Fires on Structural Members and Assembly
Battery Abuse Testing - Battery and cell destructive testing
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
