The standard multicell battery has had a critical makeover No longer will the battery fail if a cell fails pblockquotep idpullquotepblockquote p CEAs Sigma Cells battery can power products ranging from laptops to electric vehicles and is the worlds first threeinone battery solution with integrated inverter charging and batterymanagement functions This revolutionary technology serves as the batterys brain governing the smart use of battery cells If a cell is about to fail Sigma Cells finds an alternative pathway activating the best cells and in the process preventing downtime p p The innovative batterymanagement system BMS architecture and operating mode deliver the inverter and charging functions by default In addition to freeing up space in the vehicle the position of the batteries is flexible Because the system operates with traditional grid voltage any standard electrical outlet in any region of the world can be used for charging p p The CEA team revisited traditional battery architectures to create a multicell power supply and deliver enhanced performance by all three main functions switching charging and battery management The integrated charger and bidirectional system enable fast charging directly off the grid at no additional cost The battery lifespan is increased by 15 percent p p Electricpowered transportation is booming but the industry must solve several batterymanagement challenges said Philippe Despesse senior engineer at CEALeti Currently if one cell in a battery pack fails it generates a fault on the whole pack At best this puts the battery pack out of service until it can be repaired At worst the battery is discarded CEAswitchedcell technology will revolutionize batteries by lengthening their lifespans and reducing weight and size p p In addition to powering small electronic devices Sigma Cells smartbattery technology meets the requirements of rapidly growing electricmobility markets electric bikes cars buses and boats Production is slated to begin in September 2019 p p iVideo ia referrerpolicyunsafeurl targetblank hrefhttpsctsbusinesswirecomctCTidsmartlinkampurlhttps3A2F2Fyoutube2FiAgnHeSf7O4ampesheet51910610ampnewsitemid20181206005723amplanenUSampanchorhttps3A2F2Fyoutube2FiAgnHeSf7O4ampindex1ampmd546786548ec9694f5e151eb47ebab4035 relnofollowihttpsyoutubeiAgnHeSf7O4ia p p ibCEA Leti amp Liten will host a CEA Tech Village at booth 51253 in Eureka Parkbi p p iVisitors will see a batteryequipped with Sigma Cells technology installed on an electric bike The demonstration will allow them to remove a battery cell to prove that the battery continues working because Sigma Cells has found an alternative pathwayi p p a referrerpolicyunsafeurl targetblank hrefhttpsctsbusinesswirecomctCTidsmartlinkampurlhttp3A2F2Fwwwleticeacom2Fceatech2Fleti2Fenglishampesheet51910610ampnewsitemid20181206005723amplanenUSampanchorAboutCEALeti28France29ampindex2ampmd56838172ce7d005f2b3bf5990ea8285dc relnofollowibAbout CEALeti Francebia p p p
