Zatsopano 48 V Reference Design Zolinga Zolimbikitsa E-Bike ndi E-Scooter Development

Kufunika kwa ma bicycle a e-e, ma-e-scooter, ndi malonda ena ofananawo mosakayikira akukwera. Zowona, munkhani yonena momwe ma e-njinga amapangiraWothandizira AAC Steve Arar akuti kampani ya e-bike Lime osati kalekale idalengeza kuti afika okwera 150 miliyoni mzaka zitatu zokha. 

Kugulitsa ma bicycle panjinga pazaka zingapo zapitazi. Chithunzi chimagwiritsidwa ntchito mwaulemu Zolimbikitsa Volta

Kuthandiza kupititsa patsogolo ndikukhazikitsa sayansi yomwe imagwiritsidwa ntchito, Renesas posachedwapa watulutsa njira yatsopano yopita ku 48 V. Pogwiritsa ntchito malingaliro awo "osakanikirana bwino," Renesas akuwonetsa chiyembekezo kuti zolembedwazo zithandizira makasitomala kufulumizitsa kapangidwe kake ndikuwathamangitsa kwambiri kumsika.

Chifukwa 48 Volts?

48 V imawoneka ngati yochulukirapo, komabe imagwira ntchito inayake. 

Pachikhalidwe, 12 V yakhala gawo wamba lamagetsi pakugawa kwamagetsi muntchito zambiri. Koma pamene mayunitsi kuchokera pazida zamagetsi kupita kuma racks apakompyuta amakula ndikusowa mphamvu zowonjezera, ine²Zotayika za R zasintha kukhala zofunikira. Chifukwa chake, kuti athane ndi vutoli, mainjiniya ayamba kupanga 48 V monga wamba wamagetsi amtundu wamafakitale omwe amapereka.

Kutumiza mphamvu yofananira pakatundu pa 48 V motsutsana ndi 12 V kumapereka zochitika 16 zochepa kuposa ine²Zotayika R - palibe chomuseka. Ndipo popeza njira za e-bicycle nthawi zambiri zimafunikira mphamvu zochulukirapo pagalimoto ndi cholinga chopanga makokedwe ambiri, 48 V yasintha kukhala yachilendo pamapangidwe ambiri.

Mapangidwe A Renesas 'Reference a 48 V 

Ndili ndi malingaliro abwinobwino, Renesas tsopano wakhazikitsa njira yatsopano yosunthira ma e-bikes opangidwa pa 48 V. 

Zolinga zakusintha kwatsopano kwa Renesas. Chithunzi chimagwiritsidwa ntchito mwachilolezo cha Ma Renesas

Kapangidwe kameneka kamagwiritsa ntchito njira yodziwikiratu yothandiza pakapangidwe kamtundu uliwonse komanso njira zomwe zingagwiritsidwe ntchito kwa 24 V-48 V. Kapangidwe kameneka kali ndi ma 15 a Renesas IC osiyana siyana, owonetsedwa ndi ISL94216 16 -cell kumapeto kwa batire (BFE), oyendetsa HIP2211 100 V MOSFET, ndi RX23T 32-bit microcontroller yoyang'anira magalimoto. 

Yankho lakonzedwa kuti lizigwiritsidwa ntchito kuchokera pa batri ya 25 AHr Li-ion yomwe imayendetsa 1,600 W inverter, yabwino kufikira liwiro mpaka 5,000 rpm.

Malo Oyamba Kwambiri

Njirayi ili ndi zigawo ziwiri zofunikira kwambiri komanso zina ziwiri zomwe zingasankhidwe. Zomwe zimayambira zimaphatikizira kumapeto kwa batire (BFE) ndi bolodi yoyang'anira magalimoto pomwe mabatani omwe mungasankhe ndi bolodi yoyang'anira mphamvu yamagetsi ya Bluetooth komanso bolodi yolandila opanda waya. 

BFE imadzitamandira kuposa ma 200 mA akunja osakanikirana, omwe Renesas akuti amalola kubwezeretsanso mwachangu ndikugwiritsa ntchito mopitilira muyeso m'mapaketi akulu amabatire.

Chithunzi chojambulira. Chithunzi chimagwiritsidwa ntchito mwachilolezo cha Ma Renesas

Bokosi loyendetsa magalimoto limathandizira paketi yamagetsi ya 48 V ndipo itha kupeza 5,000 RPM pogwiritsa ntchito 1,600-W inverter powertrain yokhala ndi masensa oyang'anira magalimoto. 

Zolinga-Zapangidwira Zosankha Zoyenda

Ndikutsegulira uku, Renesas akuyembekeza kuthandiza makasitomala ake kupanga ma e-njinga komanso njira zingapo zosunthira. Mogwirizana ndi kampaniyo, yankho lake limapangidwa kuti lizigwira ntchito ngati makina opanga makina odulira makina a udzu, ngolo zamagetsi, zotsukira maloboti, zida zamagetsi, mabanki amagetsi, ndi zina zambiri. 

DK Singh, wamkulu wa gulu la maluso ndi zosankha ku Renesas, akuti, "Kusintha kwathu kwatsopano kwa 48 V kosakanikirana kumaphatikiza ma Benes a Benes a Renesas, ma MCU otsogola pamakampani, limodzi ndi magulu a analog ndi mphamvu, ndi ukadaulo wamakono woyendetsa magalimoto kuthandiza makasitomala kufulumizitsa kukachitika mphamvu zawo zochulukirapo komanso makokedwe a e-scooter ndi ma e-bikes. ”
