Ndinagula BMW i3 94 Ah yogwiritsidwa ntchito. Uku ndikuwonongeka kwa batri patatha zaka 3 - kusinthidwa kwa batri pambuyo pa 2039 :) [Owerenga]

BMW idangodzitama kuti idapanga 200 3 i2s. Galimoto yogula yatsopano ndi yokwera mtengo, koma pamsika wachiwiri mungapeze magalimoto angapo pambuyo pa kubwereketsa kwa zaka 5 zomwe zili ndi mtunda wochepa komanso mtengo wabwino. Ichi ndiye chitsanzo chomwe Reader wathu adasankha - ndipo tsopano adaganiza zoyang'ana kuwonongeka kwa batri mukope lake.

Mawu otsatirawa adapangidwa kuchokera ku zomwe adatumizidwa kwa mkonzi ndipo ali ndi mawu oyambira okhudza mitundu ya BMW i3.

Kuwonongeka kwa batri mu BMW i3 yogwiritsidwa ntchito

Zamkatimu

• Kuwonongeka kwa batri mu BMW i3 yogwiritsidwa ntchito
  • Kuwonongeka kwa batri mu BMW i3 - njira zingapo ndi kuwerengera
  • Kutsiliza: kuwonongeka ndi 4-5 peresenti, kusinthidwa kwa batri osati kale kuposa 2040.

Monga chikumbutso: BMW i3 ndi galimoto yamtundu wa B / B-SUV, yomwe imapezeka m'mitundu yokhala ndi ma cell okhala ndi mphamvu ya 60, 94 ndi 120 Ah, ndiye kuti, yokhala ndi mabatire okhala ndi mphamvu.

• 19,4 (21,6) kWh - 60 Ah (m'badwo woyamba BMW i3),
• 27,2-29,9 (33,2) kWh - 94 Ah (mtundu wokweza nkhope),
• 37,5-39,8 (42,2) kWh - 120 Ah (njira yomwe ikugulitsidwa pano).

Mfundo zothandiza zimasiyanasiyana chifukwa wopanga samapereka, ndipo pali zambiri zomwe zimachokera kumsika.

Kufotokozera kwa batire ya Samsung SDI 94 Ah yophatikizidwa mu batire ya BMW i3. Pezani mayunitsi okhala ndi zolakwika :) (c) Samsung SDI

Owerenga athu adasankha njira yapakati yokhala ndi batri ya ~ 29,9 (33,2) kWh, yodziwika kuti 94 Ah. Lero galimoto yake ili ndi zaka 3 ndipo yayenda makilomita oposa 100..

Kuwonongeka kwa batri mu BMW i3 - njira zingapo ndi kuwerengera

Kuti muwone kutsika kwa batri, m'pofunika kudziwa mphamvu yake yadzina komanso yamakono. Ndikudziwa yoyamba (29,9 kWh), yachiwiri ndimatha kuyesa m'njira zingapo.

Njira nambala 1. Ndinalichajitsa mokwanira galimotoyo ndipo ndinayendetsa makilomita 210 ndi mphamvu 92 peresenti. Kugwiritsa ntchito pafupifupi 12,6 kWh / 100 km (126 Wh / km), liwiro lapakati linali 79 km / h. Popeza ndinayendetsa 92 km pa 210% batire, ikanakhala 228,3 km pa batri yodzaza.

Malingana ndi izi, n'zosavuta kuwerengera kuti mphamvu ya batri yomwe ilipo ndi 28,76 kWh. Zimatero 3,8 peresenti (1,14 kWh) kapena 9 makilomita otayika.

Njira # 2. Njira iyi ndiyosavuta. M'malo moyendetsa galimoto, ingolowetsani mndandanda wa ntchito za BMW i3 ndikuwunika momwe galimotoyo idafotokozedwera ndi BMS - kasamalidwe ka batri. Kwa ine ndi 28,3 kWh. Poyerekeza ndi data ya fakitale (29,9 kWh) anataya 1,6 kWh, mphamvu 5,4%., yomwe ili pafupifupi 12,7 km.

Njira # 3. Njira yachitatu ndikugwiritsa ntchito mtundu wina wa ntchito womwe umalumikizana ndi galimoto kudzera pa mawonekedwe a OBD II. Kwa BMW i3, pulogalamuyi ndi Electrified. Health status index (SOH) ndi 90 peresenti, kutanthauza kuti galimoto yataya 10 peresenti ya mphamvu yake yoyamba.

Kodi mfundo zimenezi zimachokera kuti? Zovuta kunena. Mwina wogwiritsa ntchitoyo adatenga zikhalidwe zazikulu ngati poyambira ndikuwonjezera kuwonongeka kwa nthawi yopangira passivation (SEI), yomwe singapewedwe komanso yomwe poyamba "idya" ngakhale maola ochepa a kilowatt. . Kuchokera kuukadaulo wama cell (chithunzi choyamba m'mawu), titha kuwerengera mosavuta kuti kuchuluka kwa batri la BMW i3 ndi 96 maselo × 95,6Ah sing'anga mphamvu x 4,15V mphamvu zonse magetsi = 38,1kWh (!).

BMW imapereka 33 kWh yokha chifukwa imagwiritsa ntchito chotchinga pansi (i.e. sichimalola kuti zinthu zitheke mpaka kumapeto), komanso kukumbukira njira yopangira gawo la passivation.

> Kuchuluka kwa batire ndi mphamvu ya batire yogwiritsidwa ntchito - ndi chiyani? [TIDZAYANKHA]

Zitha kukhalanso kuti mphamvuyo imaganiziridwa pamisonkhano ya SOH ya pulogalamu ya Electrified. Oraz voteji osagwirizana kudutsa ma cell. Mwa kuyankhula kwina, "khalidwe la thanzi" silingatanthauze "ntchito" ya munthu.

Mulimonsemo Timachotsa zotsatira za Electrified ngati sizodalirika kwambiri., osachepera poyesa kuvala kwa batri. Komabe, titha kutenga mphamvu ya Ah (90,7) yomwe ikuwoneka mukugwiritsa ntchito ndikuyiyika pamakina a cell. Kutengera ngati timayang'ana mphamvu zochepa (94 Ah) kapena kuchuluka kwapakati (95,6 Ah), kutaya mphamvu kunali 3,5 kapena 5,1 peresenti.

Kutsiliza: kuwonongeka ndi 4-5 peresenti, kusinthidwa kwa batri osati kale kuposa 2040.

Miyezo yathu yodalirika ikuwonetsa kuti patatha zaka zitatu zogwira ntchito komanso pamtunda wa 3 km kuwonongeka kwa batri kunali pafupifupi 4-5 peresenti. Izi zimapereka pafupifupi makilomita 10 kuchepera zaka zitatu zilizonse / 100 XNUMX. mtunda wothamanga. Ndikafika pa 65 peresenti ya mphamvu yapachiyambi - malo omwe amaonedwa kuti ndi otsika kwambiri - pamene galimotoyo ili ndi zaka 23 kapena makilomita 780 zikwi.

Pafupifupi zaka 20 pambuyo pake. Ndiyenera kuganizira ngati ndikusintha batire, kapena ndigwiritsa ntchito mphamvu yocheperako komanso yocheperako. 🙂

Kodi opaleshoniyi ikuwoneka bwanji? Galimotoyo ikusamalidwa bwino, ndimalipira kunyumba kuchokera ku soketi ya 230 V kapena poyatsira khoma (11 kW). M'chaka ndimayenda maulendo angapo kuzungulira Poland pamene ndimagwiritsa ntchito magetsi othamanga a DC (DC, mpaka 50 kW). Mwina sizikukhudzana ndi kuchepa kwa mphamvu ya batri, koma ndimakonda kuyendetsa bwino kwachilengedwe ndipo nthawi zina kumatsika mpaka 12kWh/100km (120Wh/km) panjira.

Pambuyo paulendo wotero, tsiku lotsatira, galimotoyo imatha kuneneratu za mtunda wa makilomita 261 mumayendedwe a Eco Pro:

Chidziwitso cha mkonzi www.elektrowoz.pl: Ma cell a lithiamu-ion omwe amagwiritsidwa ntchito nthawi zambiri amakalamba pang'onopang'ono (mizere). Komabe, zikhoza kuchitika kuti wina amalephera mofulumira kuposa winayo, ndiyeno BMS idzafotokoza vuto la batri. Mwamwayi, pazifukwa zotere, ndikwanira kusokoneza batire ndikusintha selo limodzi lowonongeka, lomwe ndi lotsika mtengo kwambiri kuposa m'malo mwa batri yonse.

Zindikirani 2 kuchokera kwa akonzi a www.elektrowoz.pl: apa pali kafukufuku wokhudza kuchuluka kwa ma cell omwe amagwiritsidwa ntchito mu BMW i3, opangidwa ndi wopanga ma cell awa, Samsung SDI. Mutha kuwona kuti ma cell amataya mphamvu motsatira mizere yoyambira 1,5. Izi zimathandizidwa ndi deta ya msika, choncho tinawona kuti kulingalira kwa kuchepa kwa mphamvu kumamveka bwino. Nthawi yoyezedwa yanthawi 4 yantchito zonse imagwirizana bwino ndi mawerengedwe a owerenga athu:

Izi zingakusangalatseni:
