“Giga-sized Power Banks”
For Tomorrow’s Energy Storage

Energy storage comes in the simplest form of our portable chargers for smartphones where possibly more than 13,000 of these are powered up within an ISO container. Due to trends such as grid modernization and growth in large-scale utility grid systems like solar-based ESS, a significant increase of 33% CAGR is forecasted on the annual Battery Energy Storage Systems (BESS) deployments in the next 8 years until 2030, across residential, commercial and grid-size installations, supporting more than 420 GWh globally.1

Considering a 40ft. container can deliver up to 2.5MWh of storage, at least one-third of these will be deployed in commercial applications, creating a whopping 56,000 new 40ft. containerized BESS across the globe!

An essential part of the infrastructure, cables offer essential behind-the-scenes support to power new technologies in the battery segment. Besides high bending radius for tight and narrow spaces, they offer good heat resistance and high fire safety protection to meet compliance criterion.

Containerized BESS had been conceptualized to prioritise scalability and portability in its design – portable and simple to stack up to fit required higher capacities, whether to support small microgrids with solar panels or wind turbines, or to form part of important connections with large power grids; they are also built to be the same size as normal containers to be easily shipped around the world, with the flexibility of being assembled on-site. It is also crucial that components used within integrated protection and management systems within ESS are sufficient to protect against electrical hazards and fires should one occur.
Discover the 6
main functions of a BESS
A rack containing layers of battery packs or cells typically utilizing rectangular lithium-ion cells, built with ventilation ducts and cooling fans to ensure adequate thermal management. Racks are interconnected via jumper DC cables or insulated bus bars.
Battery Management
System (BMS)
BMS can be a “string” or “module” connected to the batteries. To optimize the service life of the batteries, this sub-system controls the monitoring of the main battery status with continuous data recording parameters such as voltage, current and temperature. An event or data recorder can also be found within a BMS, which has a direct 2-way communication to PMS.
Power Conditioning
System (PCS)
PCS provides inter-conversion control between the power grid (AC), renewable energy generation (DC) and battery (DC), and must ensure a seamless and uninterrupted switching between on & off-grid requirements. Some BESS designs may combine PMS with PCS in one physical cabinet.
Power Management System
The “brain” of the BESS system, PMS performs overall BESS monitoring including collecting information on battery performance, PCS operation and environmental conditions. An optional DC panel might be connected with PMS (or BMS, dependent on the design) via CAN/MODBUS. This panel contains fuses, circuit breakers or electrical relays, and would be triggered if a short circuit is detected. Video surveillance options are available when real-time footage feed is required.
Fire Protection System
The FPS module contains standard safety components including fire detection and suppression. Once a fire outbreak is picked up by surrounding sensors, electrical connections between the container and the external equipment must first be cut off. All time-dependent information such as alarms, is transmitted back to PMS.
A sub-system to monitor & regulate the environment within the BESS, some of which utilizes liquid-cooling technologies instead of air cooling. There is a constant communication to PMS.
Harness the Full Potential of Battery ESS with LAPP
Besides fulfilling industry requirements within the container BESS (i.e. RS 485, Ethernet, CAN, and Modbus), LAPP is continuously working with the market-leading manufacturers in China, Korea, Europe, and USA to provide them with a complete solution of connections and cable harnessing capabilities.
