Coulomb Solutions Inc. Obtains TÜV Certification for its 2.3 MWh Mobile BESS

Coulomb Solutions Inc. (CSI) has announced a significant milestone for its mobile energy storage sector by obtaining TÜV certification for its 2.3 MWh Mobile Battery Energy Storage System (BESS) model eBESS2.3-1.0-01. This certification confirms that the system meets all applicable UL 9540:2023 standards, crucial for the safe deployment and operation of energy storage systems.

The TÜV Rheinland certification process included comprehensive evaluations such as field inspections, technical assessments, and rigorous testing of the Mobile BESS. UL 9540 is the go-to safety standard for energy storage systems, assessing the functionality of all integrated components, including batteries, power conversion equipment, and protective systems, ensuring they operate cohesively and safely as one unit.

Key Components of the UL 9540 Certification

The certification process entails several detailed evaluations:

• - System-Level Safety Evaluation: An assessment of the overall system, ensuring that all parts work together safely. This included fire testing for the pack, cells, and individual units.
• - Component Safety Standards: Evaluation against industry standards for individual components, including battery systems and inverters.
• - Electrical and Mechanical Protection: A thorough evaluation of hazards related to electrical and mechanical damage, with the aim of preventing potential failures.
• - Controls and Communications: Testing the system's protective measures, communication between components, and fault response mechanisms.
• - Environmental and Enclosure Safety: An examination of the materials and enclosures to ensure durable, safe operation in various environments.

CSI's CEO, David Mazaika, stated, “Achieving UL 9540 certification represents a significant accomplishment, not just for our company but for our clients as well. This certification reassures customers that their mobile energy storage systems meet the highest safety standards.”

Applications of the Mobile BESS

CSI’s Mobile BESS is particularly beneficial in situations where an enhanced electrical capacity is required but where conventional grid infrastructure is inadequate, costly, or slow in deployment.
The system merges approximately 2.3 MWh of energy storage capabilities with a robust 1 MW power conversion system, allowing it to deliver 480VAC power under various demanding conditions. This makes it suitable for:

• - Commercial Fleet and Heavy-Duty Electric Vehicle Charging
• - Data Centers
• - High-Load Facilities
• - Temporary Power for Construction and Remote Work Sites
• - Utility and Grid-Support Applications
• - Events Requiring Temporary Power

The flexibility in deployment is a key selling point, as the Mobile BESS systems are designed for frequent transport, leveraging commercial-grade lithium iron phosphate (LFP) battery technology paired with enhanced thermal management and rugged design.

Additionally, CSI has unveiled an optional bidirectional Megawatt Charging System (MCS) for the next-generation eBESS2.3-1.0-02 Mobile BESS, which allows for high-power charging of compatible commercial electric vehicles and equipment. This will also undergo extensive UL testing for validation.

“Grid capacity limitations are a significant roadblock for electrification,” Mazaika explained. “Our aim is to empower various sectors—be it commercial EV fleets or construction sites—to access reliable, certified electrical power without the long wait for infrastructure upgrades.”

Conclusion

With the TÜV certification of its mobile BESS, Coulomb Solutions Inc. is poised to enhance the safety and reliability of mobile energy solutions in the commercial sector, paving the way for greater electrification across various industries.
