Abusive electrical testing of batteries, modules and cells
Test your batteries under the most severe electrical conditions
The Emitech Group carries out electrical abuse tests on batteries, modules and cells to simulate extreme and accidental operating conditions: overcharging, overdischarging and intensive cycling.The aim of these tests is to characterise the safety, electrical stability and response of energy storage systems to voltage and current drifts.

Why are electrical tests classified as abusive?
Batteries are sensitive to variations in voltage, current and charge/discharge time. Electrical drifts can lead to :
- Thermal runaway,
- Chemical or physical deterioration,
- Irreversible loss of capacity,
- An explosion or gas release.
What standards and benchmarks are covered?
UN 38.3 (T.7 and T.8 tests)
R100 (electrical safety of traction batteries)
UL 2580, UL 1973, IEC 62660, ISO 12405
The types of tests proposed for abusive electrical testing
Overload
- Load beyond rated voltage or current capacity.
- Monitoring of temperature, gases and mechanical integrity.
- Validate triggering of passive or active safety devices (BMS, fuses, valves).
Overload
- Excessive discharge below critical voltage threshold.
- Simulation of a breakdown or prolonged misuse.
- Observation of chemical decomposition and internal short-circuit phenomena.
Specific severe cycles
- Accelerated repetition of charge/discharge cycles (stress test).
- Application of non-linear or asymmetric profiles.
- Analysis of capacity drift, internal resistance and temperature rise.
