The comemso BMS tester in full-size format is the powerful test solution for battery management systems (BMS) with a standard capacity of 144 virtual cells, expandable to up to 300 cells. As a 38 U rack system and hardware-in-the-loop (HIL) tester, it realistically maps highly complex requirements in electromobility and stationary energy storage. All installed components meet the high standards of comemso's portable and MIDI systems, but offer even greater scalability for large battery systems.
The full-size BMS tester is ideal for the validation and development of battery systems in:
- Automotive: Electric vehicles (passenger cars, light commercial vehicles)
- Aerospace: Battery systems for aircraft and drones
- Stationary energy storage solutions (medium to large storage)
- Fast charging stations and high-performance charging infrastructures
- Maritime applications and rail vehicles
With 144 virtual cells, the system already covers the majority of modern BMS applications for high-voltage systems. For very large applications such as high-voltage trucks, grid storage or modular multi-pack systems, the system can be expanded modularly to up to 300 cells.
Differentiation from other comemso systems
The full-size BMS tester offers the most comprehensive test capacity within the comemso product family:
- Compared to the portable version, it offers significantly higher cell counts, more extensive fault simulations and realistic tests at high voltages up to 1,500 V.
- Compared to the MIDI system, the full-size tester enables the simulation of more than 72 up to 300 cells and thus addresses demanding high-voltage applications in the automotive, energy and transportation sectors.
- Thanks to its modular concept, the tester can be flexibly scaled and individually tailored to customer requirements.
Product features:
- Standard: 144 virtual cells, expandable up to 300 cells
- Simulation of individual cells with extremely high voltage accuracy
- Total system voltage of up to 1,500 V, modular expansion possible
