Validation of BMS (Battery Management System) for batteries
For optimum management of your batteries
Secure, optimise and validate the on-board intelligence of your energy storage systems
The Emitech Group offers comprehensive validation services for BMS (Battery Management System) systems, which are central to the control, safety and efficiency of batteries, modules and cells.Our expertise in on-board electronics, battery testing and simulation enables us to accurately assess the functional robustness, reliability and compliance of your BMS, under all conditions of use.

Why validate a BMS?
The BMS is the brain of the battery:
- It guarantees safe operation (avoids overloads, overvoltage, short circuits, thermal runaways).
- It optimises lifetime and performance (balanced cell management, capacity preservation).
- It enables communication with vehicle ECUs (CAN, LIN, Ethernet).
- It ensures traceability of events and battery life cycles.
Our BMS validation services
Functional validation
- Verification of protection functions (OVP, UVP, OCP, OTP, etc.).
- Test of SOC/SOH (state of charge/health) management algorithms.
- Evaluation of cell balancing (active/passive).
- Verification of behaviour in the event of simulated faults.
Communication and compatibility
- Communication tests on CAN, LIN, FlexRay and Ethernet buses.
- Checking synchronisation with on-board ECUs.
- Tests for compliance with the UDS (Unified Diagnostic Services) standard.
Cycles and endurance
- Long-term tests in real operating cycles on battery banks.
- Monitoring internal parameters and the response of the BMS over time.
- Analysis of sensor drift (voltage, temperature, current).
Environmental testing
- Simulation of extreme conditions: temperature, humidity, vibration, shock, EMC.
- Verification of BMS behaviour in real-life conditions (climatic chamber + load/discharge).
