Iinjongo ezintsha ezingama-48 V zoYilo loPhuculo lokuPhucula i-E-Bike kunye noPhuhliso lweE-Scooter

Imfuno yee-e-bikes, ii-e-scooter, kunye nezinye izinto ezinxulumene noko ngokuqinisekileyo ziyenyuka. Enyanisweni, kwinqaku zenziwe njani i-e-bikesIgalelo le-AAC uSteve Arar uphawula ukuba i-e-bike firm Lime kungekudala kakhulu yazisa ukuba bafikelele kwizigidi ezili-150 abakhwele kwiminyaka nje emithathu. 

Intengiso ye-E-bhayisekile kwintengiso kwiminyaka edlulileyo. Umfanekiso usetyenziselwe imbeko Umjikelo weVolta

Ukuncedisa ukuphucula nokuphuhlisa inzululwazi ezinjalo, URenesas kutshanje ukhuphe isisombululo esitsha sokuhamba se-48 V. Ukuhambisa isisombululo "njengomxube ophumeleleyo," uRenesas uvakalise ithemba lokuba uyilo lwesalathiso luya kunceda abathengi bakhawulezise uyilo lwabo kwaye babatyhalele ngokukhawuleza kwintengiso.

Kutheni iivolts ezingama-48?

I-48 V inokujongeka njengobungakanani obungenakuphikiswa, nangona kunjalo Ngokwenyani isebenza ngenjongo ethile. 

Ngokwesiko, i-12 V ibikwinqanaba levolthi eliqhelekileyo lokuhanjiswa kwamandla kwimisebenzi emininzi. Kodwa njengoko iiyunithi ezivela kwizixhobo zamandla ukuya kwiiracker zikhula kwaye zifuna amandla ongezelelweyo, mna²Ilahleko ziye zatshintsha zaba yinto ebalulekileyo. Ke, ukulwa le ngxaki, iinjineli ziye zaqala ukwenza i-48 V njengesiqhelo kuhlobo lwamandla ombane.

Ukuhambisa ubungakanani bamandla afanayo kumthwalo kwi-48 V kuthelekiswa ne-12 V kunika iimeko ezili-16 kancinci kakhulu kum²Ilahleko-akukho nto yokuhlekisa. Kwaye kuba ubuchwephesha be-e-bhayisekile buhlala budinga ukuphuma kwamandla kwi-motor ngenjongo yokuvelisa ubuninzi be-torque, i-48 V itshintshile yaba yinto eqhelekileyo kuyilo oluninzi.

Uyilo lweReferensi yoYilo lwe-48 V 

Ngale nto iqhelekileyo kwiingcinga, iRenesas isungule ngoku isisombululo esitsha sokuhamba kweebhayisekile ezenzelwe i-48 V. 

Iinjongo zesisombululo esitsha seRenesas. Umfanekiso osetyenzisiweyo ngoncedo lwe IiRenesas

Olu luyilo lwesalathiso lisebenzisa isicwangciso seemodyuli sokunceda kuyilo lwesiseko ngasinye kunye nokukhetha ezikhoyo iibhloko ezibonakalayo ezinokuthi zamkelwe uninzi lwe-24 V-48 V. Uyilo ngokwalo lunee-15 ezahlukeneyo zeRenesas ICs, eziqaqanjiswe yi-ISL94216 16 -cell yokungena kwebhetri (BFE), i-HIP2211 100 V MOSFET driver, kunye ne-RX23T 32-bit microcontroller yolawulo lwemoto. 

Impendulo yenzelwe ukuba inikwe amandla ukusuka kwi-25 AHr Li-ion ibhetri eqhuba i-inverter ye-1,600 W, ilungele ukufikelela kwisantya esimalunga nama-5,000 XNUMX rpm.

Iibhloko eziphambili

Inkqubo iqulethe iibhloko ezimbini ezisebenzayo kunye nezimbini ezikhoyo. Iibhloko ezisebenzayo ezisebenzayo zamkela ukugqitywa kokungena kwebhetri (BFE) kunye nebhodi yolawulo lweemoto ngelixa iibhloko ezikhethiweyo zibhodi yolawulo lwe-Bluetooth low-energy kunye nebhodi yomamkeli we-wi-fi. 

I-BFE ineqhayiya elingaphezulu kwe-200 mA yokulinganisa iseli yangaphandle, ethi iRenesas ithi ivumela ukuvuselelwa okukhawulezayo kunye nokusetyenziswa ngokugqithileyo kwiipakethe ezinkulu zebhetri.

Umzobo webhloko yenkqubo. Umfanekiso osetyenzisiweyo ngoncedo lwe IiRenesas

Ibhodi yolawulo lweemoto inceda ipakethi yebhetri engama-48 V kwaye inokufumana kangange-5,000 RPM isebenzisa i-1,600-W inverter powertrain eneemvakalelo zolawulo lweemoto. 

Injongo-Yenzelwe uKhetho lokuHamba

Ngolu phehlelelo, uRenesas unethemba lokunceda abathengi bayo baphuhlise ii-e-bikes kunye neendlela ezininzi zokuhamba. Ngokuhambelana nendibaniselwano, impendulo yenzelwe imisebenzi enje ngeengca, iinqwelo zombane, izixhobo zokucoca iirobhothi, izixhobo zamandla, iibhanki zamandla, kunye nokunye. 

U-DK Singh, umlawuli weetekhnoloji kunye neqela lokukhetha e-Renesas, uthi, "isisombululo sethu somxube ophumeleleyo sama-48 V sidibanisa i-Renesas 'ephezulu ye-BFE, ii-MCU ezihamba phambili kushishino, kunye neeyunithi ze-analog kunye namandla, kunye nobungcali bolawulo lweemoto zangoku ukunceda abathengi ukwandisa isantya samandla abo agqithisileyo kunye netorque yee-scooter kunye neebhayisikile. ”
