Sheet Metal Design Considerations: Energy Storage Enclosures

Today, the energy industry is facing unprecedented challenges and changes. Since fossil fuels, such as coal and oil, contribute to climate change, renewable energy sources have begun to take over fossil fuels' role in the energy industry. This is where the Battery Energy Storage System (BESS) comes into play. Equipment that stores renewable energy sources, such as solar and wind, releases the energy when needed.

ACE are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Batteries, racks, and chargers are assembled into energy storage enclosures indoors (NEMA 1 or 12) or outdoors (NEMA 3R). The equipment enclosures can be customized to meet needs in various industries, including construction, events, utilities, residential and commercial remote off-grid, and electric vehicle charging stations.

Which manufacturer Should I Contact for Custom Enclosures?

Appearance and material are the most basic features of an enclosure. An enclosure's durability is just as important as its appearance. What should we look for when selecting a manufacturer to customize the enclosure? It is recommended to have sheet metal manufacturers design, fabricate, and assemble custom enclosures.

Metal processing cabinets not only look great but are also durable and robust. In addition to looking visually appealing, sheet metal design should ensure that the process is simple, durable, aesthetic, and accurate. These advantages make sheet metal processing cabinets so popular.

Enclosure, Cabinet, and Box Designs

Generally, energy storage cabinets consist of enclosures, brackets, various switches on the panel, and indicator lights. The enclosures are usually made of stainless steel, which has a high hardness. They are mainly used to protect the outdoor cabinet's internal components. The brackets are used primarily to attach the motherboard, power supply, and drives.

Consider the following questions before starting the design process to ensure that the cabinets meet your needs. Manufacturers will be able to plan sheet metal fabrication based on a better understanding of the design.

• Where will the cabinets be located? Indoors or outdoors?
• What electronic devices and components will be installed inside the enclosure?
• How durable does the enclosure need to be?

Steps to Follow When Designing Sheet Metal Cabinets

• Select the right sheet metal type and thickness: The first step in designing a custom cabinet or enclosure is choosing the type and thickness used for its construction. A wide range of sheet metal materials is available, each with unique characteristics that make it suitable for particular applications.
• Identify the bending method and bend radius: Sheet metal cabinets and enclosures are made by bending the sheet metal with a folder. Due to the difficulty of bending sheet metal to a true 90-degree angle, the bending angle is usually curved. The degree of angle will vary depending on the tool and the bending parameters. Sheet metal manufacturers will set the appropriate parameters for the cabinet or enclosure to bend in the required bend radius. For more information on sheet metal bending, please visit the Sheet Metal Bending page.
• Choose the appropriate welding method: Welding is the next step after bending a single metal sheet. Cabinets or enclosures assembled by welding are stronger and more waterproof. For more information about welding sheet metal, please visit the "Welding Assembly Process" page.

BLIKSEN has designed and manufactured cabinets, enclosures, and equipment in various fields over the years and has extensive experience in sheet metal fabrication. The production process includes laser cutting, bending, welding, machining, grinding, and powder coating to produce precision machined metal parts. Furthermore, we provide assembly and purchase of commercial parts, as well as a reliable storage management system for proper material management.

Having a healthy respect for the type of batteries I use for my model airplane pursuits (LiPo, which have been known to energetically combust when not treated right), I am considering fabricating a metal cabinet for my built-up 24V, Wh Li-Ion battery. The cabinet would be vented to the outside to ensure any smoke/combustion is not released within my garage. For even more protection, I am even considering suspending a large plastic bag of sand over the battery -- in the event of a battery fire, the plastic will melt, dropping the sand onto the battery (another trick learned from charging LiPo's).

I am using one of the recommended BMS's from eBay, as well as carefully managing my charge controller settings.

Am I being overly paranoid or cautious? Is there a huge concern given that I have a BMS to protect from over-charge or -discharge? Or is this a prudent precaution?

One side benefit: an enclosed cabinet would make it easier to maintain battery temps above freezing, since it is located in my unheated garage.

Thanks!

Those batteries will fit inside a 40mm ammo can. Hard to come up with a better enclosure for containing a battery fire than a can designed to carry high explosives around in during a battle.

I was going to use the same cells in my RV, but the thought of trying to sleep with those cells in the same room with me became too much for my piece of mind. I finally bought a set of the 280 AH LiFePO4 cells instead.

Idea behind the ammo can is if there is a fire, I would very much like it to stay inside the box. The box is made out of 11 gauge (1/8") thick steel and the lid is very solidly constructed and attached, plus there is a very heavy duty, high temperature, rubber gasket on the lid. If anything is able to stand up to a LiNMC fire it will be this box. I really wouldn't want to drop it on my toe.



I was planning on using a pair of bit-miner cold plates (one on each side of the cells) plus redundant water cooling systems so the battery enclosure could remain completely sealed (no air flow in or out).



Want to buy some water cooling parts that are a perfect fit for your cells?

Just kidding, I will probably build a portable power station with these next year after I am done with the van conversion. Burning metallic lithium can reach degrees C which is above the melting point of steel. If we get that far, I think I will be calling my insurance agent and asking about coverage for a total loss.

Throwing water on burning batteries can cause a hydrogen explosion so that doesn't sound like a great idea either.

If a lithium-ion battery fails, it could burst into flame. Read more on how these fires start, and the advantages and disadvantages of lithium-ion batteries.
Sand, lots and lots of sand sounds like a good idea.

Glad I gave up on the idea of using LiNMC cells in my RV and switched to LiFePO4 cells.

I mean we all have to go sometime, but burning up in a completely preventable RV fire is not my idea of a good way to go.

Insufficiently paranoid or cautious. Unless the garage, its contents, and any attached structures are all expendable, I think you're better off making a detached bunker to hold the battery. Add whatever insulation and climate control necessary to keep battery happy.

Considering the Probability/Consequences matrix we use to evaluate risks, you should take steps to reduce worst possible consequences to an acceptable level.

It appears future building codes in the US will require a UL listed (in the case of lithium) battery, but make an exception for things like repurposed EV batteries if they are separated from buildings by 5'.

I got an idea. How about a catapult held down by a very flammable rope. Battery pack catches fire, launches them in an arc aimed at the backyard pool.

This sounds like a product we should be able to buy from Acme.
