Nyowani 48 V Reference Dhizaini Dhizaini Yekufambisa E-Bike uye E-Scooter Development

Iko kudiwa kwee-mabhasikoro, e-scooter, uye zvimwe zvine chekuita nekutengesa zviri pachena zviri kuwedzera. Muchokwadi, mune chinyorwa pa mae-bikes akagadzirwa sei, AAC mupi Steve Arar anoti e-bhasikoro yakasimba Lime isiri nguva refu yapfuura yakazivisa kuti vasvika mamirioni zana nemakumi mashanu emabhiza mumakore matatu chete. 

E-bhasikoro yakazara kutengesa pamusoro pemakore maviri apfuura. Mufananidzo wakashandiswa neruremekedzo Cycle Volta

Kubatsira kusimudzira nekuvandudza sainzi dzakadaro, Renesas achangobva kuburitsa mhinduro nyowani 48 V yekufamba. Achirova chisarudzo chavo "musanganiswa wakabudirira," Renesas akataura tariro yekuti dhairekitori dhizaini ichabatsira vatengi kukurumidza dhizaini yavo uye nekuvasunda nekukurumidza kumusika.

Nei makumi mana nevashanu Volts?

48 V inogona kutaridzika seyakawandisa huwandu, zvakadaro inoshanda chaizvo chinangwa chakati. 

Pachivanhu, gumi nemaviri V rave rakajairika voltage nhanho yekugovaniswa kwesimba mumabasa mazhinji. Asi semayuniti kubva kune esimbi zviridzwa kusvika kuseva racks anokura uye achida imwe simba, ini²R kurasikirwa kwakachinja kuve kwakakosha. Nekudaro, kurwisa dambudziko iri, mainjiniya vatanga kutora 48 V seyakajairwa magetsi-mhando magetsi anopa.

Kununura wakaenzana huwandu hwesimba kumutoro pa 48 V maringe ne12 V unopa zviitiko gumi nematanhatu zvakanyanya zvishoma ini²R kurasikirwa-hapana chekuseka. Uye sezvo e-bhasikoro matekiniki kazhinji achida zvakawandisa simba kuburitsa kumotokari nechinangwa chekugadzira huwandu hwakawanda hwe torque, 48 V yachinja kuita yakajairika mune akawanda magadzirirwo.

Renesas 'Referensi Dhizaini ye48 V 

Nezve zvakajairika pfungwa, Renesas parizvino yatanga mhinduro nyowani yekufambisa e-mabhasikoro akagadzirwa pa48 V.

Iyi dhairekitori dhizaini inoshandisa modular zano kubatsira mukati mekugadzirwa kweiyo yega musimboti uye zvingasarudzika zviripo mabhuroko anogona kutorwa kune akawanda 24 V-48 V. Dhizaini yacho pachayo ine gumi nemashanu akasiyana zvachose maRenesas IC, akajekeswa neISL15 94216. -cell bhatiri yekupedza kupera (BFE), iyo HIP16 2211 V MOSFET madhiraivha, uye iyo RX100T 23-bit microcontroller yemota manejimendi. 

Mhinduro yacho yakagadzirirwa kupihwa simba kubva pa25 AHr Li-ion bhatiri iyo inotyaira 1,600 W inverter, yakanaka kusvika kusvika kumhanya zvakanyanya se5,000 rpm.

Iwo Ekutanga Zvidhinha

Iyo sisitimu ine maviri epakati anoshanda mabhuroko uye maviri zvingasarudzika zviripo. Iwo epakati anoshanda anovharira anombundira bhatiri yekupinda kupera (BFE) uye mota manejimendi bhodhi nepo zvisarudzo zviripo zviripo ndeyaBluetooth yakaderera-simba manejimendi bhodhi uye wi-fi yekuchaja inogamuchira bhodhi 

Iyo BFE inozvirumbidza inopfuura mazana maviri mA ekunze masero ekuenzanisa, ayo Renesas anoti anotendera kukurumidza kudzoreredza uye kushandiswa kwakanyanya mumabhatiri mahombe mapakeji.

Iyo mota manejimendi bhodhi inobatsira 48 V bhatiri kurongedza uye inogona kuwana yakawanda seinosvika 5,000 RPM uchishandisa 1,600-W inverter powertrain ine mota manejimendi maseru. 

Chinangwa-Chakavakirwa Mafambiro Ekusarudza

Neichi kuvhurwa, Renesas anotarisira kubatsira vatengi vayo kukudziridza e-mabhasikoro uye yakawanda nzira dzakasiyana dzekufamba. Zvinoenderana nekambani, mhinduro yacho yakagadzirirwa mabasa senge lawnmowers, ngoro dzemagetsi, vanochenesa marobhoti, zviridzwa zvemagetsi, mabhangi emagetsi, uye zvimwe. 

DK Singh, director wezvehunyanzvi uye boka rekusarudza kuRenesas, anoti, "Yedu nyowani 48 V kufamba kwakabudirira musanganiswa inosanganisa Renesas 'akakwirira BFE, maindasitiri anotungamira maMCU, pamwe neanalog uye simba zvikamu, uye hunyanzvi hwazvino hweku maneja mota kubatsira vatengi kuwedzera vechiitiko chesimba ravo rakawandisa uye torque e-scooter uye e-mabhasikoro.
