Battery Safety and Energy Storage


Batteries are all around us in energy storage installations, Electric Vehicles (EV) and in phones, tablets, laptops and cameras.

Under normal working conditions, batteries in these devices are considered to be stable. However, if subjected to some form of abnormal abuse such as an impact; falling from a height; extreme environment changes or overcharging, these devices may be rendered unstable.

In an unstable condition batteries can change rapidly and, in the worst cases, vent violently with flame.

Battery safety testing from HSL

The Health and Safety Laboratory (HSL) has been closely Battery Safety Facility.pngstudying battery safety for a number of years, usingits bespoke battery testing facility to help our customers understand how best to manage the risks faced by many industry sectors during battery manufacture, storage, transport and use.

The main test facility is the battery safety chamber; a purpose built enclosure with a control room situated approximately 15 metres away, from which HSL's battery testing specialists can initiate and monitor the failure of cell and battery packs.


Features of HSL's battery safety testing facility include:

  • Measurement: current, voltage and temperature
  • Initiation: cell failures can be initiated via the application of electrical methods, heat or impact
  • Video: recording with four high definition cameras, plus the option to include specialist cameras such as thermal imaging and high speed
  • Gas sampling: in realtime or by means of sampling tubes
  • Residue analysis: samples can be taken of residues for later analysis by specialist HSL teams


Additional testing facilities from HSL

In addition to our dedicated battery safety chamber, the HSL site spans more than 550 acres in which large scale bespoke fire and explosive experiments are conducted. Such large scale, highly energetic testing has been conducted safely on our site for more than 40 years.

Besides open field tests there are a number of vessels of varying shapes and sizes across HSL's wider estate that can accommodate high pressure rises. The largest of these vessels has an internal volume of 3600 cubic metres. These vessels could be used for larger scale, enclosed battery testing.
