In the race to hit ambitious global net zero targets, a further two billion EVs need to be on the road by 2050, according to the International Energy Agency. To power these #green motors, lithium-ion batteries are absolutely essential.
But what happens when those batteries are defective? Even before assembly into a working engine, traction batteries are typically transported with a small level of charge. This is because a fully discharged battery poses problems for both the manufacturer and consumer; problems such as lower capacity, faster depletion and electric shorts—which can cause fires to ignite.
Regardless of where in the supply chain this occurs, unexpected ignition can cause catastrophic damage to life, vehicles, and transport infrastructure.
SICK AG, a market leader in the global sensor manufacturing industry, has developed a system for detecting at-risk batteries, helping businesses prevent battery fires before they can cause serious damage.
Fighting battery fires with FLIR thermography
Having successfully developed a system that detects hot spots and potential fires on ferries and in tunnels vital to transport infrastructure, such as Switzerland’s 10.5-mile-long Gotthard Road Tunnel, SICK AG was recently presented with an exciting opportunity within an especially challenging timescale.
The company was approached by a German #automotive manufacturer to detect potential issues in #ev batteries on a new assembly line. The challenge? To design, test and implement an interface for identifying thermal runaway in battery production in just three months—a process that, by their own admittance, would typically take over a year to see through to completion.
That's why SICK AG approached #teledyneflir to supply the most suitable thermal imaging technology for the task.
The system required a bespoke interface that could accurately test each battery for thermal runaway, and then export and transmit the data to a server to be cross-referenced and analyzed where anomalies were found to be present.
After careful consideration of the scale of the hot spots to be detected by this state-of-the-art system, SICK AG chose to build its new Area Hotspot Detection System (AHD) around the FLIR A70.
