What Does the Boeing Li-Ion Battery Fire for EVs?

Japan’s GS Yuasa Corporation, made the ill-fated lithium-ion that caught fire in a 787 Dreamliner earlier this is also a major supplier of for electric cars. It has joint with both Honda and and its cells are also in some Peugeot/Citroen (PSA) cars.

year, GS Yuasa opened a in Shiga Prefecture capable of 50,000 Mitsubishi i -MiEVs, and as reported it is ramping up production as of Honda’s key lithium-ion battery to supply 15 million cells (triple Honda’s previous

Honda’s Very Safe

Honda’s joint-venture plant GS Yuasa is called Blue Yuuji Fujiki, chief for Honda’a IMA hybrid system, in 2011 that its li-ion are “very safe” and operate at low temperatures. Even if a needle is into the battery, he said, fire is not going to break

Honda is standing by its batteries. spokesman Chris Naughton PlugInCars.com, Our battery is completely and not based on the battery [in the Boeing We have subjected our battery to testing (including extensive testing and piercing it with a metal rod) to ensure it safe and stable.

Jack Nerad, an analyst for Blue Book, describes the battery incidents as certainly in the context of an aircraft, perhaps a less so in auto applications.

are ongoing in the Boeing fire, a second incident in which a was forced to make an emergency in Japan after a smoke went off and a pack was found to be Overcharging has been ruled out as a Meanwhile, the Federal Aviation has recently visited GS Yuasa in and company officials say they’re with the probe.

The Wall Journal reported, Regulators yet indicated whether they the cause of the Dreamliner problems with the battery itself or another piece of the complex system of which it is a part. A within the batteries could U.S.-based Boeing from a and expensive redesign of the systems.

Earlier this month, GS said it had received Ministry of subsidies to allow a rapid ramp-up to become “one of the manufacturers in the world.” GS Yuasa 51 percent of the Kyoto plant, and 49 percent.

What Lies

It’s not too early to speculate the airline mishaps might for an EV industry heavily dependent on technology. These batteries to run warm, as everyone knows. Wald reports in the New York “The electrolyte in a lithium-ion includes hydrocarbons.

So it will burn or at least a chemical reaction somewhere of fire that generates and smoke.If the lithium-ion battery is then it has a big surface area with the volume of its ingredients, and it can heat well. If it is large, or if it is a of many cells, a cooling has to be installed or a path set up for air to flow

Many EVs have such systems, but the Nissan LEAF is many that don’t. batteries have a checkered when it comes to fire In 2006, several computer including IBM, Dell and recalled laptop computers of fires attributed to Sony batteries.

Last year, sale of Chevy Volts was set back by reports of lithium-ion catching fire following crash tests. That took place weeks the test, and occurred only a heavily damaged battery was left in the car and suspended upside But there were also fires involving electric though none clearly the EV.

Big Advantages to Li-Ion


Lithium-ion in airplanes offer weight rapid charging and very energy storage and delivery, the basic advantages for electric Boeing’s use of the batteries was approved in with stringent safety part of the deal.

Nobody has hurt in the Boeing battery or in the auto-related fires, either. unlikely that we’ll see a retreat from li-ion it’s by far the most efficient technology in the world today. But we may see a effort to make the batteries as as they possibly can be.
