Environmental testing for batteries, modules and cells
Validate the robustness of your batteries under extreme and multi-physical conditions
The Emitech Group offers a range of environmental tests for batteries, modules and cells to simulate the physical and climatic stresses to which these energy storage systems may be exposed throughout their life cycle.
These tests guarantee the safety, reliability and compliance of batteries in demanding environments.

Why carry out environmental testing?
Batteries can be subjected to a number of combined stresses:
- Abrupt thermal variations (freezing/thawing, hot engine, air conditioning, etc.)
- Constant or cyclical humidity (tropical zones, condensation)
- Accidental immersion, water splashes, dust in industrial environments
- Salty or corrosive atmospheres
- High altitude (aeronautics, transport, mountains)
- Insulation or corrosion faults,
- BMS malfunctions,
- Loss of tightness or chemical degradation,
- Thermal runaway in the event of an uncontrolled reaction.
What are the applications?
Light and heavy electric or hybrid vehicles
Railway and marine batteries
Batteries for the aerospace industry
Stationary or industrial systems in constrained environments
Types of environmental tests proposed
Thermal cycling and thermal shocks
- Rapid alternation between extreme temperatures (from -40°C to +90°C)
- Reproduction of engine, climatic or seasonal cycles
- Analysis of the pack's mechanical and electrical resistance
Hygrometric cycling (humidity)
- Relative humidity control from 10% to 95% RH
- Simulation of successive condensation and drying
- Observation of the effects on insulation, housings and connections
Tightness tests - IP Protection Indices
- IPX4 to IPX9K (spray, splash, high-pressure cleaning)
- IP5X and IP6X (ingress of dust or particles)
- Tests in pressure, immersion or contaminated atmosphere
