Electrical and performance testing are used to test system electrical performances on modern test benches so that their efficiency and reliability can be improved.
System behaviour and ageing are observed using different tests performed by SERMA Energy:
- Characterisation testing
- Endurance testing
- BMS validation testing
- Other: Contact us
Our various test benches are coupled to secure climatic and thermal chambers (-40 to +120°C; 0 to 95% RH).
Additional chillers for your systems are available on request (-40 to +120°C).
We carry out electrical and performance testing in climate chambers equipped with a double power analyser and a high-capacity battery simulator (up to 500 kW, 1200 V, 1200 A).
Thanks to our advanced acquisition system, we can accurately evaluate the efficiency of motor systems and power electronics (e-machines, AC and DC).
Compliant with the main standards ISO 12405, ISO 16750-2, ISO 21780, ISO 21782-2, LV123, etc., our equipment can be adapted to your needs to ensure reliable and customised testing.
Our tests are carried out for 3 main fields of application:
SERMA Energy has major electric cell, module and pack testing resources with a wide range of performances:
Cells
- 9V / 15A
- 5V / 300A
- 8V / 300A
- 8V / 500A
- 20V /1000A
Modules
- 150V / 800A
- 100V / 50A
- 100V / 150A
Packs
- 500V / 300A
- 700V / 400A
- 1000V / 1000A / 250kW
- 1200V / 1200A / 500kW
- Up to 1MW
We have testing resources for Power Electronics (inverters, converters, chargers, components).
Our battery simulation power test benches can achieve 1200V 1200A 500kW.
We also have the capacity to simulate:
- Vehicle computers and complete vehicle environments,
- Electric motor operation
- Charger or smart charger operation (vehicle to grid).
SERMA Energy has several high and low speed electric motor test benches and modular back to back benches.
Our e-machine test benches
Double output motor test benches (20krpm / 3500rpm) fitted with:
- A 500kW, 1200V, 1200A battery simulator,
- Separate chillers,
- 2 MHz power analysers
- Over 100 measurement channels.
The maximum mechanical power is 368kW at high or low speed.
Low speed makes it possible to reach high torques, such as 4000Nm.
Our modular test benches
This bench is capable of housing different testing configurations:
- Front to front: two face-to-face machines coupled using a high speed torque meter
- Back to back: two complete drive chains linked to each other by a transfer box making it possible to use one drive chain as a motor and the other as a brake. This set-up is especially interesting for mechanical strength endurance validation. The limits of this assembly are: 35000rpm or 5000Nm or 800kW.
- eGMP: a pull chain connected to two 3500 rpm low speed charge motors.
MARTILLAC, NEW TEST CENTER DEDICATED TO ELECTRIC MOBILITY
In 2025, SERMA Energy opened a 6,500 m² building dedicated to support its customers’ for battery and e-mobility development.
This new state-of-the-art, fully automated testing facility is equipped with high-performance equipment to validate the safety and performance of tomorrow’s technologies:
- 250 cell testing channels (500A)
- 50 module testing channels (300V/ 500A)
- 67 climate chambers from -40°C to +90°C
.
The entire cycle and system conditions are simulated and analysed using the varied tests and trials proposed by SERMA Energy:
