Battery Energy Storage Systems (BESS) are critical assets in today’s energy infrastructure, used for frequency regulation, renewable integration, and grid support. As these systems are typically housed in heavy-duty containers, ensuring structural integrity during transportation, installation, and operation is essential. One of the most crucial steps in quality assurance is the lifting test—a mandatory procedure to validate the container’s ability to withstand dynamic forces during hoisting.

At TLS Energy, we specialize in the design and manufacturing of containerized BESS solutions. Serving top-tier energy clients globally, our containers are built to the highest standards. We conduct rigorous lifting tests to simulate real-world handling and certify structural safety.

What is a Lifting Test?
A lifting test is a structural assessment where a fully assembled BESS container—often loaded with steel blocks (dummy weights)—is lifted using certified lifting equipment. This test ensures the container frame, corner castings, and welds can bear the full load without deformation or damage.
In the test, simulated loads—often 20,000 kg or more, as shown in the image—are strategically placed to mimic real battery system weights. The container is then lifted from designated lifting points to evaluate:

  • Structural stability
  • Frame integrity
  • Weld joint quality
  • Lifting lug alignment and strength

These tests confirm the container complies with international safety standards, and they are essential for offshore or large-scale utility applications where safe handling is non-negotiable.

TLS Energy’s Lifting Test Standards
TLS Energy performs lifting tests in strict accordance with international container safety codes and engineering best practices. Each BESS container undergoes:

  • Visual inspection before and after lifting
  • Deflection and stress analysis during the test

As the global energy landscape shifts towards decentralization and carbon neutrality, advanced Energy Management Systems (EMS) have emerged as a cornerstone for the operation of smart grids and virtual power plants (VPPs). A new generation of EMS platforms now enables real-time control, intelligent scheduling, and full integration of distributed energy resources (DERs), driving energy efficiency and cost savings across industrial parks and microgrids.

Integrated PV, Storage, and EV Charging Optimization
Modern EMS platforms are built on the principle of “PV-Storage-Load-Charging” coordination. Using AI-powered forecasting algorithms, EMS can accurately predict photovoltaic (PV) generation based on weather data and historical trends. This ensures real-time adjustment of battery charging and discharging. Surplus solar power is automatically stored or redirected to EV charging stations, reducing curtailment and increasing renewable energy consumption.

Battery energy storage systems (BESS) serve multiple functions within the EMS framework. They enable peak shaving and valley filling based on dynamic electricity pricing, provide frequency regulation, and serve as backup power sources. The EMS intelligently schedules charge/discharge cycles to minimize peak demand charges and leverage low-tariff periods, enhancing both cost-efficiency and grid stability.

In response to the surge in EV adoption, EMS platforms incorporate smart charging strategies. They aggregate charging demand data, regulate charging loads during grid peaks, and prioritize off-peak charging. This reduces pressure on the local power infrastructure and cuts charging costs for end users. In some industrial parks, this strategy has reduced peak loads by 30% while increasing battery utilization by 20%.

Deep Integration of Distributed Energy and Grid Services
With the rise of solar and wind energy, managing intermittency and ensuring grid reliability has become increasingly complex. EMS platforms now aggregate distributed PV, BESS, and controllable loads into virtual power units. This “resource pooling” approach smooths fluctuations and enhances grid responsiveness by discharging during peak demand and absorbing excess energy during oversupply periods.

To maintain power quality, EMS platforms integrate power quality monitoring, harmonic filtering, and voltage control systems. Real-time analytics detect abnormalities and deploy compensation measures to ensure stable operation. Embedded fault diagnostics reduce downtime and enhance system safety.

In industrial settings, EMS supports multi-energy coordination including PV, combined heat and power (CHP), and waste heat recovery. These systems dynamically optimize energy flows based on cost and availability, prioritizing low-carbon sources and minimizing emissions.

The Future of Virtual Power Plants
At the heart of VPP evolution is the EMS, which transforms distributed resources into flexible, market-ready assets. VPPs can now provide grid services such as frequency regulation, demand response, and energy arbitrage in real-time electricity markets. EMS platforms analyze real-time pricing and consumption forecasts to determine optimal participation strategies, maximizing economic returns for asset owners.

​Future EMS innovations include AI-driven autonomous dispatch, cross-regional resource aggregation, and blockchain-based transaction validation. These technologies will enable EMS to support larger, smarter, and more decentralized VPP ecosystems, accelerating the global transition to a low-carbon, resilient energy future.

Positive Pressure Explosion-Proof is a widely adopted method used in hazardous environments to prevent explosions by maintaining a higher internal pressure within a sealed container. This controlled internal overpressure effectively blocks the ingress of flammable gases or vapors from the surrounding atmosphere, thereby reducing the risk of explosive gas mixtures forming inside the container.

1. Creating a Protective Barrier Through Pressure Differential
At the core of Positive Pressure Explosion-Proof lies the physical principle of gas diffusion—from high-pressure zones to low-pressure zones. By maintaining a slight overpressure inside the container, any external flammable gas is effectively prevented from entering. This isolation ensures that even if explosive gases are present outside, they cannot mix with the air inside, reducing the possibility of ignition.

2. Disrupting the Fire Triangle
The fire triangle consists of three essential elements: fuel, oxygen, and an ignition source. An explosion can only occur when all three are present simultaneously. The positive pressure system ensures that the conditions for the formation of explosive gas mixtures inside the container are not present by preventing combustible gases from entering the container, and that even if an ignition source and oxygen are present, an explosive environment will not be formed, thus effectively avoiding the risk of explosion.

3. Structural Integrity and Material Considerations
For positive pressure systems to function reliably, the container must be structurally sound and well-sealed. High-quality sealing prevents pressure loss, while the materials used must withstand internal overpressure and resist corrosion from external environmental factors. These design elements are critical to maintaining system integrity over long-term operation in harsh or hazardous conditions.

4. Monitoring and Control Systems
Maintaining stable internal pressure is crucial for effective explosion protection. Positive pressure systems typically incorporate pressure sensors, regulators, and control interfaces to monitor and adjust internal pressure levels.
When the internal pressure drops below the preset threshold, the pressurization system—either automatically or manually—can be activated to restore positive pressure. Conversely, if the pressure exceeds safety limits, exhaust or relief valves are engaged to prevent over-pressurization and potential structural damage.
This dual mechanism ensures both safety and reliability, accommodating various operational scenarios where full automation may not be practical or necessary.

Conclusion
Positive Pressure Explosion-Proof provides a practical and effective solution for safeguarding electrical equipment, control systems, and instrumentation in hazardous areas. By maintaining an internal overpressure, it minimizes the risk of explosive atmospheres forming inside enclosures, significantly enhancing operational safety.
With its widespread use in industries such as oil & gas, petrochemicals, offshore operations, and energy storage systems, understanding and properly implementing this technology is essential. Whether in design, commissioning, or maintenance, a deep understanding of positive pressure principles ensures compliance, safety, and long-term system performance.

In high-risk industries such as oil & gas, chemical processing, and offshore platforms, explosive gas atmospheres pose significant safety challenges. According to the IEC 60079-10-1 standard, industrial sites are classified into Zone 0, Zone 1, and Zone 2 based on the frequency and duration of the presence of explosive gases. Each zone comes with distinct requirements for the design and construction of functional enclosures, and understanding these differences is critical for safety and regulatory compliance.

Zone 0: Continuous Explosive Atmospheres

Zone 0 is the most dangerous explosive atmosphere and usually refers to internal spaces such as fuel tanks or chemical reactors where explosive gas mixtures are present continuously or for long periods of time.
As a rule, the installation of any non-essential enclosures or electrical equipment in Zone 0 should be avoided.If necessary, only intrinsically safe (Ex ia) or encapsulated (Ex ma) equipment according to IEC 60079-11 is permitted.The system should have continuous gas monitoring capability and be able to trigger an automatic power-off or alarm mechanism when a set threshold is reached.This ensures reliable operation in extreme Zone 0 environments with complete protection against dust and prolonged submersion in water.

Zone 1: Occasional Explosive Atmospheres

Zone 1 is an area where an explosive atmosphere may occur during normal operation, such as an offshore drilling rig work area or an oil refinery pump room.The enclosure must be protected by one or more of the following methods: explosion-proof (Ex d), pressurised (Ex p) or combined (Ex db + Ex pb).The pressurised system must ensure that the pre-blowing volume is at least 5 times the internal volume of a typical gas (according to IEC 60079-2) or 10 times the internal volume of hydrogen.A pressure monitoring interlock must be installed to automatically shut down the system if the pressure falls below 50 Pa (typical threshold; actual values may depend on product specifications or project requirements).Depending on the environment in which the equipment is installed, the enclosure should have a protection rating of not less than IP54 (indoor) or IP65 (outdoor) to ensure that the dust and water resistance meets the requirements for use.A two-channel gas detector should be installed with an alarm threshold set between 10% and 25% of the LEL (lower explosive limit).Materials must be explosion-proof, anti-static and corrosion-resistant.

Zone 2: Rare and Abnormal Explosive Atmospheres

Zone 2 areas experience explosive gas atmospheres only in abnormal conditions and for short durations, such as gas station ventilation zones or transition areas adjacent to Zone 1. Allowed equipment types include increased safety (Ex e), non-sparking (Ex nA), restricted breathing (Ex nR), and simplified pressurized enclosures (Ex pz). Even simplified systems must ensure a 5x air volume purge before energization. For outdoor enclosures, materials such as 316L stainless steel is recommended, with steel containers having a minimum thickness of 3 mm and GRP containers a minimum thickness of 8 mm(These thicknesses are based on industry best practices or product-specific standards, not on IEC mandates.).

Conclusion

All explosion-proof container designs must strictly follow relevant standards, including IEC 60079, ATEX, and GB 3836. A few critical points to note: The commonly used designation “Ex de” is non-standard. The correct classification is “Ex db eb,” indicating a compound flameproof and increased safety solution. Pressurized containers (Ex p) are not permitted in Zone 0 and are only applicable in Zone 1 and Zone 2.
Each hazardous zone imposes increasing or decreasing demands on functional container design. Zone 0 allows only intrinsically safe or encapsulated equipment, Zone 1 requires multi-layered explosion protection strategies, and Zone 2 allows simplified protections but still requires adherence to core safety standards. By aligning design and manufacturing with the appropriate zone classification and international standards, equipment safety and operational integrity can be fully assured in explosive gas environments.

As global energy demand continues to rise and renewable energy adoption accelerates, energy storage technologies have become crucial to the success of the energy transition. Among these technologies, energy storage containers have emerged as a versatile and modular solution, offering flexibility in deployment and scalability across various applications—such as grid balancing, distributed generation, and emergency power supply.

1. Material Selection
The choice of materials directly impacts the container’s performance, reliability, and overall cost-effectiveness. Common materials used in the industry include:

1.1 Weathering steel(Corten steel)
Currently, weathering steel is a widely used structural material for energy storage containers.It has good mechanical strength, welding performance and cost advantages, and is suitable for mass production and complex structure manufacturing.Weathering steel can also form a stable corrosion protection layer on the surface, which improves its corrosion resistance and prolongs its service life.Compared to stainless steel, this type of steel ensures structural strength while significantly reducing material cost and weight, which is a good balance between performance and economy.

1.2 High-Strength Composites
High-strength composite materials have gained popularity for their lightweight, high durability, and abrasion resistance. These materials allow for optimized structural dimensions, making containers easier to install and transport, while maintaining reliability and strength.

2. Structural Design
A well-engineered structure is critical to ensuring safety, functionality, and efficiency. Key areas of structural design include:

2.1 Energy Storage System Configuration
The storage system is the core of the container. Design considerations should include battery capacity, voltage range, and cycle life, with a focus on maximizing energy storage efficiency and system longevity.

2.2 Thermal Management
Effective thermal management ensures optimal battery performance and extends lifespan. Designers must consider heating efficiency, temperature control, and energy-saving strategies. Forced air cooling or liquid cooling systems are commonly used to regulate internal temperatures.

2.3 Ventilation
Proper airflow is essential to maintain a safe and stable internal environment. Ventilation design should take into account air intake volume, humidity control, and temperature distribution to ensure the container remains within operational limits.To avoid the build-up of gases (e.g. thermal runaway gases), the installation of a gas venting and detection system should be considered.

2.4 Interface Design
Interfaces affect installation, commissioning, and overall user experience. Consideration should be given to the number, type, and placement of AC/DC and communication ports to enhance system integration and ease of maintenance.

3. Safety Performance
Safety is a core element in the design of energy storage vessels and is directly related to the reliability of equipment operation and personnel safety.The following are the key safety performance points:

3.1 Fire safety
The fireproof design should comply with international safety standards, such as UL 94, UL 9540A, IEC 62619 and so on.The structure of the container should be made of materials with high flame retardant rating and equipped with automatic fire extinguishing system, such as aerosol, dry powder or water mist system, if necessary.At the same time, exhaust channels should be reserved to cope with the release of gases after thermal runaway of the battery to reduce the risk of explosion.

3.2 Electrical Safety
The electrical system should be equipped with a battery management system (BMS) and an energy management system (EMS) to realise real-time monitoring and protection against over-charging, over-discharging, short-circuiting, over-temperature and other conditions.The system should meet IEC 62933, GB/T 36276 and other safety standards for energy storage systems to ensure that the power can be cut off quickly in case of failure and protect the equipment from further damage.

3.3 Moisture protection and sealing
Humid environment will cause corrosion and insulation risk to the battery performance and electrical components, so the container should have good sealing, the recommended protection level is not less than IP54 (indoor) or IP65 (outdoor).Waterproof seals, moisture-proof coatings and dehumidification modules are used to effectively control the internal humidity and ensure the long-term stable operation of the system.

3.4 Personnel and Operation and Maintenance Safety
The design should fully consider the operation safety of maintenance personnel.The container should be equipped with obvious safety warning signs, emergency stop switches, and enough space reserved for access.At the same time, in order to adapt to the trend of intelligence, it is evolving to support remote monitoring, abnormal alarm and remote power failure, which will help to respond quickly in unexpected situations.The structure and electrical layout of the vessel should comply with IEC 60204, OSHA, GB 50898 and other ergonomic and operational safety standards.
