Thermal shock and cycling test

Moving a cell or pack rapidly between temperature extremes, typically −40 °C and +60 to +85 °C, for many cycles, to find seals, welds and housings that fail by differential expansion. It is in UN 38.3, R100 and most pack specifications.

UN 38.3

The United Nations test sequence that every lithium cell and battery must pass before it can be shipped: altitude, thermal cycling, vibration, shock, external short, impact or crush, overcharge and forced discharge. Air shipment of cells also caps state of charge at 30 %.

Venting

The controlled release of gas and vapour from a cell whose internal pressure has risen too far, through a vent designed to open before the case bursts. The vented gas is flammable and toxic, so packs route it away from occupants.

Vibration and shock test

Shaking a cell or pack on a vibration table to a profile standing for years of road use, and striking it with defined mechanical shocks, then checking for loose connections, leaks and loss of isolation. UN 38.3, R100 and ISO 12405 each specify a profile.
