Carrar says its immersion-cooled battery architecture stops thermal runaway even with a cell above 800 °C
Carrar says testing at its R&D lab showed its Two-Phase Immersion Architecture can prevent thermal propagation between high-energy NMC pouch cells even under extreme failure conditions. In the test, a 72 Ah pouch cell was driven into thermal failure with a temperature rise exceeding 15 °C per second, and the triggered cell rose above 800… Read more »
Raytron develops thermal imaging tech for EV battery thermal runaway prevention
Infrared thermal imaging firm Raytron has unveiled its new thermal imaging technology for monitoring the lithium-ion battery lifecycle to prevent thermal runaway failures. Infrared thermal imaging is a non-contact technology that can provide the necessary real-time, visual temperature data to intervene before a full-blown lithium battery fire is triggered. At the early signal detection, the… Read more »

Mitigating EV Battery Thermal Runaway Risks With Simulation Technology
Electric vehicle fires often become big news stories, but what actually causes them? A chain reaction inside the battery—called thermal runaway —causes the battery to generate excess heat and catch fire. Regulations have been put in place so that once a thermal runaway issue has been detected in the battery pack, occupants of the car… Read more »
