Sam­sung shows new 100 km bat­tery at Euro­bike 2015

The Witness - Wheels - - BIKING -

SAM­SUNG has un­veiled an e-bike bat­tery pack that can run for 100 km with a sin­gle charge.

The South Korean bat­tery maker is par­tic­i­pat­ing at the Euro­bike 2015 in Friedrichshafen, Ger­many, to show­case its var­i­ous lithium-ion bat­tery tech­nolo­gies for elec­tric bi­cy­cles.

Euro­bike is the world’s largest bi­cy­cle trade fair that has around 1 300 in­dus­try com­pa­nies from 54 dif­fer­ent coun­tries at­tend­ing each year. Start­ing from 2012, this year will mark Sam­sung SDI’s fourth par­tic­i­pa­tion.

Sam­sung SDI will ex­hibit six types of stan­dard­ised bat­tery packs that can ei­ther be built in­side or in­stalled on the out­side for im­me­di­ate use. It will also dis­play 12 types of bat­tery packs that are cur­rently be­ing supplied to global man­u­fac­tur­ing com­pa­nies and cells of var­i­ous spec­i­fi­ca­tions. Another tech­nol­ogy worth notic­ing is the ad­di­tion of a Blue­tooth func­tion which will en­able users to check on their smart­phones for resid­ual bat­tery charge, re­main­ing dis­tance, and other data, while rid­ing their bi­cy­cles.

The 500 Wh bat­tery pack, un­veiled for the first time by Sam­sung SDI, has achieved its slim size by in­cor­po­rat­ing high ca­pac­ity cells and su­pe­rior bat­tery pack tech­nol­ogy. It can also run for a 100 km with a sin­gle charge by hav­ing max­imised energy stor­age.

Re­cent vi­tal­i­sa­tion of the ecofriendly e-bi­cy­cle mar­ket and higher de­mand for long dis­tance prod­ucts — due to diver­si­fi­ca­tion into leisure, com­mut­ing, and other us­age — have prompted Sam­sung SDI to de­velop its high ca­pac­ity bat­tery packs.

Sam­sung SDI also un­veiled a bat­tery pack prod­uct equipped with 21 700 bat­ter­ies, noted for their up­graded energy ca­pac­ity com­pared to pre­vi­ous cylin­dri­cal types.

The 18650 bat­tery, or rather the small cylin­dri­cal bat­tery of 18 mm di­am­e­ter and 65 mm length, has been in dom­i­nant use un­til re­cently.

How­ever, the cre­ation of new bat­tery ap­pli­ca­tions has boosted the de­mand for high ca­pac­ity bat­ter­ies. In re­sponse, Sam­sung SDI has come up with a bat­tery that has up­graded energy vol­ume by a max­i­mum of 35%, now known as the 21700 bat­tery, and has suc­cess­fully ap­plied it to e-bikes in a world first.

The 21700 model can have var­i­ous ap­pli­ca­tions other than e-bikes, such as in elec­tric tools, lap­tops, and more. It is ex­pected to be­come the new stan­dard in small cylin­dri­cal bat­tery us­age.
