No Certifications Given Out for UL9540A and 1741 is Next ?...just trying to put the pieces together, looks like the UL9540A is for the installation part and No certificate will be given...
As a test method, UL 9540A testing does not provide a certification, UL Mark, or pass/fail results,” said Maurice Johnson, business development engineer with UL’s Energy Systems and e-Mobility group. “The information from UL 9540A testing supports important safety decisions about how the BESS will be installed and used. The best way for manufacturers to share that their energy storage battery products have been tested for thermal runaway is to list them in the UL 9540A test database.” Because an ESS includes multiple components, the UL 9540 standard actually encompasses two other, older standards: UL 1973 (for the stationary battery pack) and UL 1741 (for the inverter). These two individual standards – in conjunction with rigorous thermal and electrical testing and evaluation of the components working together as a system – comprise the UL 9540 certification. This is why products need to be tested for reliability before coming to market. For electronic goods, the best way to do it is to get a UL 9540 certification. UL will test your product and make sure that it’s reliable enough to meet industry safety standards and standards for UL 9540 energy storage.
DEFINITION OF UL 9540
UL 9540 is a safety standard for an energy storage system (ESS) and equipment intended for connection to a local utility grid or standalone application. It designates key issues associated with ESS. These include:
- Safety of the battery system
- Functional safety
- Fire detection suppression
- Containment
- Environmental performance
- And more
DEFINITION OF UL 9540A
UL 9540A, on the other hand, is a test method for evaluating thermal runaway propagation for battery energy storage systems. This will not give you the certificate! Instead, it will provide data for manufacturers to see if their product meets the regulations.
This is very useful for engineers and developers to verify the effectiveness of the product’s protection against key issues like fire.
The Test Hierarchy of UL9540A
There are 4 stages in the UL9540A test method:
#1 - CELL LEVEL TEST
At this level, UL looks at whether a cell can exhibit thermal runaway. It also checks its characteristics and flammability.
...... you’re shopping for an ESS, don’t worry about UL 1973 and UL 1741 because as long as you see a “UL 9540” or “Certified to UL 9540” mark on an ESS ensures the system you plan to entrust you home power storage needs to is safe and designed to perform at a high level.
