How the thermal runaway test chamber works?
As the valve-regulated battery uses a poor liquid design, the electrolyte poured into the battery is adsorbed on the fiberglass board. When the charging current increases, the gas needs to be released through the safety valve, which causes the battery to lose water and increase the internal resistance. The capacity decay and generate a lot of heat during charging and discharging. If the heat is ...

Monitoring Off-Gasses to Guard Against Thermal Runaway Risk with Li-Ion Batteries
Lithium-Ion Batteries Rechargeable lithium-ion (“li-ion”) batteries (comprised of cells in which lithium ions move from a negative electrode through an electrolyte to a positive electrode during discharge—and the other way around when charging) were first described conceptually in the 1970s. Following initial prototype development in the 1980s, li-ion batteries became ...

Fiber Optic Testing Helps Ensure EV Battery Health and Safety
EVs face unique design challenges in order to be competitive with gasoline-powered vehicles. The root of many of these challenges is in the EV battery pack. Drivers want similar vehicle range per charge when compared to a tank of gas, as well as the convenience they are used to with refilling a tank in just a few minutes. This means battery packs need to be able to store enough energy to go ...

Heat Flux Sensing in Battery Monitoring
Batteries are critical devices for many people today: they power smartphones, laptops, and even cars! The wide adoption of batteries was possible because of the invention of the lithium-ion battery (whose inventors won the Nobel Prize this year). If we look at its results, the Li-Ion battery was surely one of the most important engineering achievements of the last 50 years. Given its importance, ...

Battery Failure Prevention with Proper Mitigating Actions
Lithium ion battery failure follows four primary stages, which are initial abuse, off-gas generation, smoke generation, and fire propagation. Both the initial abuse and off-gas generation stages fall within what’s called the “preventative region”. In that region, specifically during the off-gas stage, implementing proper mitigating actions can help prevent battery failure. As ...

Reducing fire and explosion risk of lithium-ion batteries
On the 7th January 2013 cleaning staff onboard a Boeing 787 aircraft noticed smoke in the rear cabin. Closer inspection by a mechanic discovered a fire originating from the lid of the APU battery case. Fortunately, the plane was parked at Logan International Airport, USA, at the time, so none of the 183 passengers and 11 crew were hurt. Nine days later, on 16th January 2013, a Boeing 787 had to ...

Hydrogen Detection and Control
How Lead-Acid Batteries Release Hydrogen Lead-acid batteries produce hydrogen and oxygen gas when they are being charged. These gasses are produced by the electrolysis of water from the aqueous solution of sulfuric acid. A Vented Lead-Acid (VLA) battery cell, sometimes referred to as a “flooded” or “wet” cell, is open to the atmosphere through a flame-arresting vent, and ...

“Sealed Maintenance-Free” Batteries. What a Myth!
The term “Sealed Maintenance-Free,” in my opinion, is a marketing-driven term. In the early 1980’s, when telephone Private Branch Exchanges (PBX’s) were being deployed into customer premises, computer mainframes were migrating out of dedicated computer rooms, and smaller computers were being situated in occupied office space. Consequently, users were demanding that the ...
