As an independent non-profit organization, the Electric Energy Research Institute (EPRI) works with the electricity sector to make electricity safe, reliable, affordable and environmentally friendly. As a component of this mandate, EPRI conducts research, progression and demonstration projects to gain public benefits in the United States and around the world. It’s about testing promising products and technologies in cooperation with key utility companies.
In recent years, EPRI has focused on comparing and testing technologies to increase the safety of battery-powered garage systems (BESS). Comprised of an interconnected series of Li-ion batteries, BESS is helping utility companies deliver reliable backup power, peak heavily and buy energy generated through renewable energy systems.
However, despite the significant benefits, BESS is subject to thermal leakage situations that occur when excessive heat caused by mechanical defects or disorders resulting from damage or malfunction of the formula creates a temperature-increasing reaction. If not controlled through the built-in protections of the battery control formula or formula (BMS), this procedure can continue to increase the temperature and voltage until the battery mobile breaks, which can cause fires on affected and adjacent mobiles.
For this reason, EPRI performs checks with several utility companies for an early precautionary formula that may stumble on a fuel release occasion as a precursor to a thermal leak up to 30 minutes before a cascading failure. This unique and recognizable early caution signal is helping to mitigate the challenge or close the formula before heat runoff can even begin.
“Once a BESS lithium ion enters thermal leakage, you cannot avoid it [in this cell]; its purpose is to verify to prevent the spread of heat and thermal leakage to adjacent cells,” says Paul Rogers, a retired New York Firefighter, co-founder of Energy Storage Response Group (ESRG), a national chimney protection consulting firm with nearly 50 years of combined experience specializing in threat assessment, matrix research, and electrical garage system safety testing.
While still running for the New York Fire Department, Rogers oversaw the implementation of the department’s first reaction protocols on how to manage energy garage systems, and now consults nationally on this issue and protection testing.
According to Rogers, while a battery control formula (BMS) can provide information and close the BESS, depending on the degrees of protection integrity of the BMS component, the BMS would possibly ignore critical signs or malfunction. For this reason, Rogers recognizes the need for a separate redundant formula that may involve the possibility of thermal leaks before it happens so that the BESS can be closed to save it.
“You want layers of coverage at your risk,” says Rogers, who recommends incorporating an additional early caution formula in addition to THE BMS.
While looking for the safety of the electric garage formula in New York, Rogers discovered a product called Li-ion Tamer that provides a complex precaution before thermal leakage in lithium-ion BESS. To Rogers’ knowledge, no other product does this in the same way as Lion Tamer technology.
The early detection of thermal runaway relies on four sequential stages of Li-ion battery failure, according to Steve Cummings, Director of the Sensors Business Unit at Nexceris, an Ohio-based developer of gas sensors and monitors. The company worked with the U.S. Navy a decade ago to develop an off-gassing detection technology for Li-ion BESSs that would later be commercialized into the Li-ion Tamer product, which is compatible with all Li-ion chemistries.
“A cello-powered lithium-ion phone starts to fail when it undergoes abuse such as heat, overvoltage, etc.,” Cummings says. “The step of the moment is degassing. The third level is the smoke and the fourth step is the chimney. But smoke and chimney occur almost simultaneously. Therefore, during the time smoke is detected, thermal leakage has already started regularly.”
Off-gassing usually occurs due to a breakdown of a Li-ion battery cell electrolyte, as a result of pressure buildup. Later, temperature increases, smoke is emitted and then fire breaks out.
To trip over fuel at the earliest level of a battery after initial abuse, the Li-ion Tamer formula provides a battery fuel monitor and a network of sensors specially designed for lithium-ion batteries.
Fortunately, the EPRI is reviewing Li-ion Tamer at various control sites. This includes Duke Energy’s Emerging Technology Innovation Center in North Carolina, which has validated the system’s ability to stumble upon small fuel release lines as a precursor to a thermal leak minutes before it occurs, deterring imaginable cascading faults. Based on this success, Duke Energy, a member of the EPRI, implements generation and makes it a popular practice.
Duke Energy, a Fortune 150 corporation in Charlotte, North Carolina, is one of the largest tenure corporations in États-Unis.La corporate materials power for 7.7 million retail electricity consumers in six states, serving approximately 24 million people. It also provides herbal fuel to more than 1.6 million consumers in five states and operates wind and sun services in 14 states.
According to Tom Fenimore, Duke Energy’s recent Director of Business Development, which is helping with the deployment of complex new technologies, the company has been testing Power Garage for over a decade and has been contacted through EPRI and Nexceris as a test for this. Reason.
“We were in education in lithium-ion energy storage, deterring thermal leak events, when we had the opportunity to paint with Nexceris and install its fuel release detection generation [in a BESS], which detects thermal leaks so that it can be deterred,” Fenimore says.
According to Fenimore, on the Mount Holly, North Carolina site, a pre-production edition of Li-ion Tamer was first tested on a BESS and then innovations were incorporated into a modernized production edition. Today, the Li-ion Tamer is used and continues to be probed in a BESS in a 20-foot container that has been professionally developed and built for energy storage. The BESS has a power of 650 KWH and can discharge approximately 350 KWH of power. It has six racks of lithium-ion batteries that are used daily in the operation of the micro-lad that supports the Mount Holly Technology Innovation Center.
“We are adopting a proactive technique to enhance the safety of the garage that comes with the implementation of protective layers,” fenimore says.
Fenimore claims that the first line of defense is the battery control formula (BMS) because it is the formula that manages the speed and discharging of batteries. This is the first formula that you can stumble upon if there is a prohibited condition in a battery cell. Because it monitors voltage and temperature, you have the first opportunity to put the battery in condition on occasion.
“The next generation point deployed in our BESS systems is Nexceris Li-ion Tamer, which is deployed inside the container to stumble if a mobile battery has passed in a state where it emits fuel,” Fenimore explains. “This occasion of lack of fuel is a direct indication that the battery is in a compromised state. At this point, we take this sign and turn off the battery, disconnect the battery from the network, ventilate and cool the battery and alert others so that proper maintenance can be performed to fix the problem.
Fenimore says Duke Energy was involved in an offsite disruption by actively hitting battery cells in a state of thermal leakage under controlled conditions.
“We’ve noticed in the tests that we have an early notification of a few minutes that an occasion [before the heat wave] occurred when even a few seconds can make a difference,” Fenimore says. “We need to leverage this capacity anywhere we can to protect the public and the capital assets we deploy.”
According to Fenimore, Duke Energy has projects or planned in six states that use the technology.
“Nexceris’ Li-ion Tamer generation is popular in our BESS protection specifications and we specify it to move forward,” fenimore says. “BESS are implemented with sun, wind or sun combinations and classic generators. BESS meets the regulatory needs for a wireless election because it does not require the structure of more distribution lines or transmission lines to get the power to where it wants to go.”
For utilities and other stakeholders, when it comes to securely integrating new electrical workshop technologies into the municipal code, ESRG’s national security consultant Paul Rogers emphasizes the importance of adding sufficiently good safeguards to any incident that can derail and gain broader support.
According to Rogers, in the 1970s in New York, there was an explosion at a liquefied herbal fuel (LNG) facility that had nothing to do directly with LNG. projects will be installed in the city without exception because the branch of the chimney will not allow it,” Rogers says.
The lesson, according to Rogers, is one that the battery energy storage industry should take to heart when it comes to rolling out lithium ion BESS technology: taking the time to fully test and implement safe equipment, methods and procedures always pays off in the end.

Resilient force and battery garage solution to supply transparent backup force to force interruptions.
EnTech Solutions recently introduced its latest micro-network technology, Xcape. These scalable sets are agile strength and garage responses that enable companies to resist strength and drive sustainability goals.
Today’s businesses are more exposed than ever to costly power outages. Commercial and commercial companies (C-CIs) lose thousands of dollars every time there is a flash of strength or a power outage, and for many, those cuts are a monthly or even weekly event. The Xcape micro-network is a rugged battery and force garage solution that can supply transparent backup force to force interruptions.
“Many companies are theoretically interested in micro-burning generation, but they don’t know where to start and can’t handle engineering, buying and building one from scratch,” said Scott Romenesko, president of EnTech Solutions. “We have taken over our study and progression (R&D) activities in micro-network generation and have created a product that we know works and can be superior or reduced to satisfy our customers’ power generation desires.”
To maximize and optimize renewable force consumption, Xcape works with the force generated by solar panels and retail outlets with excess strength in its battery system. When you do not have the force of the sun due to the canopy of clouds or at night, Xcape supplies strength from the battery system. When connected to an electrical grid, the force of the network can be used if you are not going to have the force of the sun and battery. These three systems make advertising operations reliable and resilient at all times.
“Food continuity is especially for corporations facing product loss and profits when lighting devices are turned off,” Romenesko said. “Xcape is helping to solve this challenge for food manufacturers, restaurants, advertising offices and many other industries.”
