As well as being a shock hazard it could unbalance the battery, or even become a dead short which might start a fire or cause the battery to explode! Note that the same readings could be caused by multiple leakage points, and/or bulk leakage across surfaces or inside the insulation, particularly if a cell has been leaking electrolyte.
Even though battery leak rate standards have yet to be established, HMSLD is the preferred choice as the leak rate required to ensure battery tightness is in the 10–6 to 10–10 atm-cc/s range or lower.
After the battery cells pass the ionization leak test, the next phases are putting several cells together to create a battery module, combining the modules into a battery pack then putting several battery packs together into a battery tray. Each of these battery packages requires leak testing.
If the leak rate is within testing specifications, the battery packaging is airtight. ATEQ accompanies its customers in their production and assembly process of batteries for electric vehicles.
