Battery Backup Thermal Runaway Fears? Render it Harmless Through Continuous Monitoring
Tom Shannon, Director of Business Development • BatteryDAQ, Inc.
Thermal runaway is the disaster no one saw coming until it is too late. It sounds like a horror movie, and it could well be, if batteries are not properly maintained. Every article on the subject will point out something like “If the design of the battery, coupled with the installation location, allows for proper dissipation of increased battery temperatures, thermal runaway is unlikely”. <read more>

Expanding Technology for Advanced Battery Applications & Fuel Cells
 Dexmet has taken the “Expanding Technology” to the next generation of advancements, the micro-mesh material manufactured by Dexmet is infinitely variable, and the proprietary equipment developed anddesigned at Dexmet produces expanded material with smaller holes than anyone else and produces material that is thinner than anyone else in our marketplace. The expansion process produces a very consistent product as far as open area, hole size and conductivity.
Dexmet expanded materials are perfect for Advanced Batteries Applications and Fuel Cells, especially where you are using multi stacks of materials and you need consistent conductivity from stack to stack also the expansion process is more cost effective unlike perforated material.
The expansion process allows you to yield higher amounts of material than what you put in, this is especially important when your application requires expensive materials like platinum, niobium, zirconium and titanium.
KEMA Testing Validates Use of Spring Contact Element Performance in High-Current Applications
 Bal Seal Engineering, Inc., a producer of custom-engineered conducting solutions for equipment used in high-current applications, has subjected its Bal Spring canted coil springs to third-party testing to demonstrate how well the springs withstand KEMA’s rigorous short circuit current exposure and cycling. The results will enable the company to provide customers with verified performance data, including continuous, short-circuit and peak current ratings and electrical resistance per spring coil.
Short circuit current testing of springs made from two highly conductive copper alloy materials was conducted at 1 second and 3 seconds at power levels up to 65,000 amps to determine the average maximum current each material could withstand. An additional test was also conducted to demonstrate the number of cycles a single spring could withstand when a short circuit current of 3 seconds is applied repeatedly.
Jim Harty, Bal Seal Engineering’s global market manager for energy, says the third-party testing validates the company’s internal testing and highlights the spring’s ability to endure the harsh conditions found in high-current power transmission and distribution applications.
“Our springs are already at work in some of the world’s most demanding high-current applications,” said Harty. “But the test results give us an unbiased, accurate means to represent their performance. More importantly, they provide our customers with an added level of confidence that the springs we engineer with these alloys will meet their toughest requirements.”
Tests were conducted at KEMA’s Powertest Laboratory using a fabricated device designed to replicate standard groove and spring design configurations commonly used in high-current applications such as gas-insulated switchgear. Each device included a housing, a piston, a spring, and an insulator ring.
The test springs were installed in a housing-mounted configuration using grease to simulate actual customer usage. Both the piston and housing were made of copper (UNS C11000) and plated with 10–15 μm of silver with a PEEK insulator ring to prevent an undesired short between the pin and the housing.
The tested springs were made of highly conductive copper alloys and silver plated. According to Harty, increasing plating thickness is recommended if a high amount of short circuit current cycles are required.
“Knowing how the springs performed in the tests,” says Harty, “allows engineers to better predict real-world performance and the life of their electrical contact elements.”
