Why the Current Hoverboard Battery Scare Doesn’t Apply to Electric Cars
is actually there something in your garage, along with perhaps charging up to currently, he features a great opportunity to shock the outbreak unexpectedly in a fireball?
we actually do not they pointed rifles electric vehicles or plug-in hybrids, along with we’ll explain why shortly. We are talking about hoverboards. For those whose minds still go to anything as cool as hoverboard “real” of Back to II future -or impossible wonderful, nitrogen coolant surprise of Lexus last year along with we We salute you. Still This specific hurts to see tweens along with Martha Stewart Made in China consumer along with bogarted term, subbing in cheap mobility device, all over the place, along with the defects without serious bike-handling. along with one that will is actually, This specific turns out, is actually very dangerous.
earlier This specific week, after trying for several months to reel in This specific Wild West of the market with the threats just a disciple of detention along with for the Consumer Product Safety Commission (CPSC) announced the call of more than half a million of what we will unfortunately call through currently on hoverboards. With This specific news, car enthusiasts along with geeks are likely tool, consider Where did your mind: Well, if I have to worry that will the hoverboard from the garage, I have ever had to worry about This specific incendiary risks in an electric car or plug-in hybrid?
In short, almost certainly not. Yes, both the use of lithium-ion cells, although there are many differences, including a separate design along with manufacturing differences that will separate the two countries.
products, “the vast majority of hoverboards available from the market are made cheaply, introduced to the bare minimum cost point,” says Sam Abuelsamid, senior analyst with the research Navigant. He said he suspected that will the manufacturers hoverboard choices battery to achieve maximum power with minimum space along with cost. Do not play automakers that will. They are taking a conservative approach with batteries along with aiming for a longer shelf life along with predictable performance in temperatures along with conditions.
lack of quality control along with monitoring of temperature = hell
along with This specific’s not just the quality of the battery installed packages in This specific means of transport, although the bare minimum of battery management, which often fail to detect when the battery access high temperature seriously, either when charging or discharging when the systems quickly. Many of these personal batteries also electronics provide higher energy density than they should peacefully, said Abuelsamid, along with they are not made with the same care along with accuracy, or quality control of automotive grade cells or even the kind that will you want to find in personal devices first division of Apple or Samsung.
Specifically, the case takes the form of the uneven distribution of heat, often resulting through manufacturing or material defects from the electrodes. Eventually fractures along with to minimize the electric cell. At This specific point, with some chemistry, electricity can ignite spontaneously.
, “Electrolytes are usually organic compounds that will contain oxygen,” said Abuelsamid. “Once ignited, they tend to be self-sufficient.” There have inflamed wounds of your hoverboard, star of social media in some cases, along with in some other cases of serious disaster from the doing.
does not look familiar, though
On the surface, these batteries hoverboard may seem eerily familiar? Some cells use a bag that will does not differ much through what used phones Apple along with tablets, or modest, cylindrical in shape, almost AA 18650 size for the Coordination of cells that will look is actually almost the same as in 7000 or so of these that will are crammed in every Tesla style S sedan or Tesla style X SUV
sure: what you see is actually not what you get. Automotive grade cells are very, very different: made accurately along with precisely control the temperature of the lithium-ion along with lithium polymer battery cells, with the chemistry that will has been carefully selected to keep their cool
auto manufacturers along with suppliers design these systems to be extremely durable along with compliant with federal safety standards. Exposed packs for crash testing along with is actually designed to prevent infiltration. Temperature management is actually also one of the stability of car batteries packs keys “along with longevity. is actually monitored temperatures even at the cellular level in some packages, cooling systems along with air conditioning help to maintain stability in a spot of sweet, which is actually from the range of 30 to 50 ° C . This specific is actually not only because This specific helps to raise capacity, although because This specific helps to prevent the unloading in both directions overcharging or complete that will the cells can be damaged.
along with group chemistry
chemistry used from the automotive along with electronics evolve constantly, for the most part, are safe along with stable. while the Chevrolet volt earlier along with some designs of the current leaves are used chemistry spinel manganese, the next Chevrolet Bolt , the fresh edition of the volt, along with last 30 kWh Nissan LEAF the use of nickel, manganese along with cobalt battery (NMC), which provides more capacity along with stability.
there were a few exceptions. one of the former chemistry of lithium-ion, lithium cobalt oxide , This specific has been at the root of many of the issues the fire of Higher definition: Sony Vaio laptops several years ago, along with the Boeing 787 Dreamliner lately. Because of the presence of oxygen, from the case of an internal short, along with were more prone to ignition batteries of This specific type. This specific has been used to chemistry in Tesla, along with while the package in This specific form is actually not a problem in itself, along with Tesla since moved to a different configuration of the style S along with style X chemist, along with has been found on the distribution box in one particular root (wide) Tesla style S Fire .
Back in 2009, the safety of consumer products in a series of claims through the fires on the iPod appeared along with decided that will there was no need for further action. After This specific time the harmful smell of burning plastic, for months, as all the major airlines from the United States banned the hoverboards by earlier This specific year, along with issued until the Department of Transportation warning about battery packs, along with ask them to be treated as a hazardous material. currently, after hoverboards erupt in smoke along with flame such a familiar scene in American driveways that will Saturday Night Live parodied the phenomenon .
from the spirit of shanzhai, a lot of brands are familiar a little bit, along with these designs are all kind of look alike . along with Swagway X1 is actually a very common style that has a higher volume of recall (267,000 units). Segaway, another one of the brands hoverboard, along with already marketing boards as a “fire-resistant.” For these flights, which typically cost $ 300 to $ 900 along with can go nearly 10 miles on a charge, in some cases, This specific is actually not all that will surprising that will manufacturers skimped on the batteries go to the high energy density (along with vacation ready production) with heat control on what apparently, very little or charge control

adventure that will has taken over the lifetime of the product is actually an important way to frame This specific hoverboard offense. While the smartphone may continue for a few years before you retire, your children may use hoverboard for the summer before I forget from the back of the garage, This specific is actually still required to perform for eight or ten years from the automobile. “the automobile manufacturers can not afford to get their cars to explode, or to pay for warranty claims on the battery is actually $ 15,000,” said Abuelsamid.
from the end, This specific looks a lot like the entire industry, eager to compete from the low cost point is actually impossible, that will their products are shipped before fully test This specific out.
