Sheet Metal Enclosures Fabrication for Battery Energy Storage

Recently, the battery boxes manufactured for a new energy storage project were delivered smoothly and passed the inspection by the customer, which was well received.

The order has about 300 units of battery enclosures, which are made of 1.5mm thick carbon steel material and processed in three weeks through CNC punching, bending, riveting, welding, painting and packaging.
The customer inspected the product strictly and was very satisfied with the quality of the product.

In recent years, we have offered sheet metal fabrication services for many kinds of metal boxes, and our products are widely used in electric buses, port AGV transfer vehicles, electric trucks, power plant energy storage systems, charging piles, and other vehicles and other energy storage devices.

This batch of metal boxes is used for battery energy storage.

What is battery energy storage?

Battery energy storage systems are rechargeable battery systems that store energy from solar arrays or the electric grid and provide that energy to a home or business. Because they contain advanced technology that regular batteries do not, they can easily perform certain tasks that used to be difficult or impossible, such as peak shaving and load shifting.

STEP 1: CHARGE
During daylight, the battery storage system is charged by clean electricity generated by solar.

STEP 2: OPTIMIZE
Intelligent battery software uses algorithms to coordinate solar production, usage history, utility rate structures, and weather patterns to optimize when the stored energy is used.

STEP 3: DISCHARGE
Energy is discharged from the battery storage system during times of high usage, reducing or eliminating costly demand charges.

What’s Inside a Battery Storage System?

Each energy storage unit contains several components: one or more battery modules, onboard sensors, control components, and an inverter. In DC-coupled units, a separate inverter is used. In AC-coupled units, the inverter is integrated into the system. These components make energy storage systems more than mere batteries.

Multiple, swappable battery modules prevent an entire energy storage unit from going down if one battery module fails. The module can be swapped out for another with no downtime.

Sensors ensure safe operation and allow for remote monitoring. Onboard sensors help maintain appropriate operating temperatures, watch for battery module failure, and report usage data to you and your energy company.

Control components mean energy storage systems can be set up, however, they need to be to perform their intended job without any ongoing user intervention. For example, batteries can be configured to charge automatically when energy is cheapest and discharge automatically when it’s most expensive, or they can be configured to store energy in case of a power outage simply.

Integrated inverters make installation easy and inexpensive. While DC-coupled battery storage systems with separate inverters can be cheap, efficient, and good for off-grid homes, they offer much less flexibility than AC-coupled units with integrated inverters. AC-coupled units, like Tesla’s Powerwall 2, have more capabilities, work without solar arrays, and are easier to install. Modern systems simply plug into an existing power network.

Best-in-class energy storage systems have a few more key components: built-in cooling systems, weatherproof construction, and scalable architecture.

Built-in cooling ensures optimal performance. Weatherproof construction means energy storage systems can be mounted outside without the added cost of protective structures. Scalable architecture means multiple energy storage units can be linked to form a larger system. Additional units can always be added later.

Taken together, these components make battery energy storage systems safe, scalable, and cost-effective.

Battery Boxes, Cabinets, and Enclosures of All Shapes and Sizes
Openex manufactures indoor and outdoor industrial enclosures to meet the needs of the Battery and Energy Storage industries. With the increasing importance for renewable energy sources, and the inherent need for backup battery power for some industries, you need storage for the energy and power supply. That’s where stationary battery enclosures, boxes and houses come in.

Construction of Battery Storage Enclosures
Every Battery Enclosure is manufactured to spec, meeting size and weight load requirements of your project.
Electrical enclosures can utilize a variety of metals, most commonly we utilize steel. Other metals, such as aluminum, galvanized steel, and stainless steel these enclosures can also be fabricated using galvanized steel, and Galvanneal can be used.
Most enclosures, cases and houses are finished with wet paint, powder coat, aluminum, galvanized, Galvanneal, or stainless steel passivation.
