AI will detect EV battery fires: Honeywell in research

According to the SMEV, India sold 8.47 lakh electric two-wheelers in FY-23 despite the rash of EV fires in 2022. The number of sales is 2.5 times the 3.28 lakh electric scooters that were sold in the preceding fiscal.

AI will detect EV battery fires: Honeywell in research

If there was one thing that hindered the sale of

electric two-wheelers in India

last year, it was the high number of e-scooter fires. The global technology leader Honeywell is developing technologies at a facility in Chicago that might defy the norm. By 2025, the company's soon-to-be-launched AI solution will be able to anticipate battery fires, or thermal runaways as they are officially termed, in order to save both drivers and the battery.

A cheap solution is also on the way, which Honeywell claims is perfect for electric scooters and three-wheeled scooters. "We're designing two different types of solutions — the primary one is the lithium-ion battery off-gassing solution, but we are further developing solutions that sense hydrogen, and that hazard is very applicable to the two- and three-wheeler vehicle markets," said Sarah Martin, Presiden of Safety and Sensing Technology, at Honeywell.

The duality results from the hydrogen-detection system probably being a low-cost one built specifically for markets with a high e-scooter penetration rate. "For a simple two-wheel vehicle, it needs to be a relatively simple solution," Sarah continued. "The solutions we're developing and talking to manufacturers are a sweet spot for that."

An AI use case and a sensor suite that is built to monitor aspects like off-gassing and changes in battery pressure will combine in the aforementioned technology before being sent into a data management system. The AI is anticipated to forecast thermal runaways and give users LIVE feedback when combined with prior learning. 

Thermal detection technology, which offers a reduced warning window or time period to consumers of an oncoming EV battery fire, is relied upon by EV customers today. A little more sophisticated device may anticipate an oncoming fire and work to cool the EV battery. On the other hand, Honeywell's AI solution aims to completely avoid the heat incident.

Honeywell is in discussions with Indian e-scooter producers to provide the technology to the Indian market, however, it won't name any specific companies. The business claimed to be in talks with battery producers as well. "There's close collaboration with the OEM and then there's direct engagement with battery manufacturers too," added Sarah. In the end, OEMs always want to be the ones that own the reference design so they can platform it.

For Honeywell, the


market in India may present enormous possibilities. According to the Society of Manufacturers of Electric Vehicles (SMEV), India sold 8.47 lakh electric two-wheelers in FY-23 despite the rash of EV fires in 2022. The number of sales is 2.5 times the 3.28 lakh electric scooters that were sold in the preceding fiscal. It still falls short by 25% of the goal established by entities like Niti Ayog.

According to a recent CNBC-TV18 story, Honeywell is optimistic about its chances in the Indian green hydrogen industry since it plans to provide catalyst-coated members (CCMs) to businesses that make hydrogen electrolysers. CCM samples from the firm have already been delivered to a number of nations, including India.

Given the National Green Hydrogen Mission's goal of producing five million metric tonnes of green hydrogen annually, these CCMs may be essential to India's aspirations for a green energy future. Gavin Towler, Chief Scientist (Sustainability Technology) of Honeywell, stated: "We've been working with our team in Gurugram and our laboratories in Chicago to create that technology for a few years now.

However, he said, "We'll work with all the companies that are building electrolysers." He went on to say, "We'd want to be the supplier of the chemistry technology to anyone who manufactures the electrolysis plants."

Plans by Honeywell will be influenced by things like investments made in battery manufacture and hydrogen generation by OEMs and energy giants. However, the firm is confident about its possibilities since sustainability targets are becoming more ambitious than previously and because many companies want to accomplish these goals sooner rather than later.
