Kulumikizana kwa BMS kwa Kuphatikiza Kusungirako kwa Dzuwa: Kugwirizana kwa CAN, RS485, ndi Inverter Protocol

Chifukwa Chake Kulumikizana kwa Inverter Ndiko Kulephera Kwambiri kwa Malo Osungiramo Zinthu ndi Dzuwa

Lankhulani ndi aliyense amene walamula kuti malo osungira magetsi a dzuwa asungidwe pamlingo waukulu ndipo mudzamva nkhani yofanana: paketiyo inapambana mayeso onse pa benchi. Ma voltage a ma cell mkati mwa spec, kulinganiza ntchito, chitetezo chikuyaka monga momwe amayembekezera. Kenako pamalopo, inverter ndi batri zinakana kulankhulana - kapena choipa kwambiri, zinalankhula, koma zinanena za momwe magetsi alili olakwika, zinakana malamulo oyendetsera magetsi, kapena zinaponya ma code olakwika omwe palibe amene akanatha kuwazindikira. Paketiyo inabwerera kunyumba. Ntchitoyi inatayika sabata imodzi.

Iyi si nkhani yosowa kwambiri. Ndi imodzi mwa zolakwika zomwe zimachitika kawirikawiri m'mapulojekiti osungira mphamvu ya dzuwa, ndipo nthawi zambiri chifukwa chake chimakhala chimodzimodzi: BMS yomwe ili ndi doko la CAN, koma siimalankhula za njira yomwe inverter imayembekezera. Makamaka posungira, kulumikizana si chinthu chofunikira - ndi maziko omwe makina amayimira.

Njira Zitatu — Zimene Chilichonse Chimachita Mu Dongosolo Losungira Zinthu

Kulankhulana kwa BMS kosungira mphamvu ya dzuwa nthawi zambiri kumagwiritsa ntchito njira zitatu zakuthupi, iliyonse yokhala ndi njira yosiyana yoyendera. Kudziwa njira yomwe imagwira ntchito polemba njira yothandiza yolumikizirana ndi iti:

Basi ya CAN

Ulalo wofunikira kwambiri pakati pa batri ndi inverter. CAN imanyamula malire a state-of-charge, charge ndi discharge current, voltage limit, fault flags, ndi mauthenga owongolera a protocol-specific. Iyi ndi njira yomwe inverter imadalira kuti idziwe momwe ingalipiritsire ndikutulutsa batri mosamala. Ngati CAN yalephera kapena ikulankhula protocol yolakwika, makina ena onse alibe chilichonse chogwira ntchito.

RS485

Imagwiritsidwa ntchito poyang'anira pang'onopang'ono, telemetry, komanso kuphatikiza ndi makina oyang'anira mphamvu pamalopo kapena mapulogalamu apamwamba owunikira. RS485 ndi njira yolumikizirana yodziwika bwino yamakina ambiri okhala ndi unyolo wa daisy komwe paketi iliyonse imanena kwa wowongolera. Modbus RTU ndiye njira yodziwika bwino yolumikizirana iyi.

bulutufi

Kwa okhazikitsa ndi ogwiritsa ntchito — pulogalamu ya foni yam'manja yomwe imawonetsa ma voltage a ma cell, kutentha, momwe zinthu zilili, komanso mbiri ya alamu. Siili mbali ya kuzungulira kwa pompopompo; yothandiza pakuyambitsa, kuthetsa mavuto, komanso kuwonekera bwino kwa ogwiritsa ntchito.

Kusiyana Kofunika Kwambiri: Kukhala ndi CAN Sikutanthauza Kulankhula Pulogalamu Yanu ya Inverter

Gawoli ndi lofunika kuchepetsa liwiro, chifukwa ndi pomwe kugula zinthu zambiri pa spec-sheet kumalakwika. CAN bus ndi muyezo weniweni komanso wamagetsi - njira yosunthira ma bits pakati pa zida modalirika. Si protocol. Ma protocol ndi mapangano okhudza tanthauzo la ma bits amenewo: ndi uthenga uti womwe uli ndi state of charge, kapangidwe ka byte komwe kamayimira malire a charge current, ndi ma code olakwika ati omwe amafotokozedwa.

Magawo awiri a BMS akhoza "kuthandizira CAN" ndipo sangathe kulankhula ndi inverter imodzi, chifukwa amagwiritsa ntchito ma protocol osiyanasiyana. BMS yomwe imathandizira mawonekedwe a CAN wamba koma sigwiritsa ntchito kapangidwe ka uthenga komwe inverter yanu ikuyembekezera idzapanga kulephera komwe kwafotokozedwa pamwambapa: mawaya alumikizidwa, magetsi akuyaka, ndipo palibe chothandiza chomwe chimasinthidwa.

Ma Protocol a Common Storage Inverter, ndi Zomwe Chithandizo Chachikhalidwe Chimatanthauza

Padziko lonse lapansi, malo osungiramo zinthu m'nyumba ndi m'mabizinesi ang'onoang'ono agwirizana ndi njira zochepa zosungiramo zinthu (inverter protocols). Mndandanda weniweni womwe pulojekiti imafuna umadalira mtundu wa inverter womwe watchulidwa, koma kukambirana kumakhala kokhudza mitundu ikuluikulu yomwe ikutumikira msika uliwonse wachigawo. Pansi pa mulingo wa mtundu, pali kuzama kuwiri kogwirizana komwe kumafunika kumvetsetsa:

Chithandizo cha protocol yachikhalidwe

Firmware ya BMS imagwiritsa ntchito protocol ya inverter mwachindunji. Nthawi zambiri, kuyambitsa kumakhala kosavuta chifukwa protocol yakhazikitsidwa kale pamlingo wa firmware - ngakhale zinthu zina monga mtundu wa protocol, mtundu wa firmware mbali zonse ziwiri, mapping a parameter, ndi kasinthidwe ka inverter mbali zonse ziyenera kutsimikiziridwa kuti zigwiritsidwe ntchito molondola. Izi ndi zomwe zimachepetsa kulephera kwa malo poyerekeza ndi njira yokhazikika kapena ya CAN yokha, pomwe gawo la protocol palokha liyenera kupangidwa kapena kusinthidwa kuwonjezera pa zonse zomwe zili pamwambapa.

Thandizo losinthika / losinthika

BMS imapereka CAN ndi mawonekedwe osinthira a upper-monitor omwe amalola kuti protocol isankhidwe kapena kusinthidwa kuti igwirizane ndi inverter inayake. Izi ndizosinthasintha koma zimafuna kuti wokhazikitsa kapena wogulitsa adziwe zomwe akuchita panthawi yoyambitsa.

Chiyanjano cha CAN chokha

BMS ili ndi doko la CAN koma siigwiritsa ntchito protocol ya inverter. Cholumikizira chikuyembekezeka kupanga gawo la protocol lokha. Pa mapulojekiti ambiri osungira zinthu izi sizothandiza pamalonda - nthawi yaukadaulo imadula kwambiri kuposa kusankha BMS yokhala ndi chithandizo chachilengedwe.

Funso lothandiza pa RFQ iliyonse yosungira: kodi mukufuna yoyambira, yokhazikika, kapena mukufunadi kupanga gawo la protocol? Okhazikitsa ambiri amafuna yoyambira. Opanga mapaketi omwe amayendetsa mapulojekiti angapo m'mitundu yosiyanasiyana ya inverter nthawi zambiri amafuna yokhazikika.

Momwe Mungatsimikizire Kugwirizana Musanayitanitse

Uwu ndi mndandanda wa zinthu zomwe ziyenera kuchitidwa pasadakhale (pre-RFQ checklist) zomwe zimaletsa kulephera komwe kwafotokozedwa pachiyambi. Kugwira ntchito kumatenga nthawi yosakwana ola limodzi, ndipo kumapulumutsa milungu ingapo pambuyo pake:

• Tsimikizani kaye inverter yanu, osati BMS.Inverter nthawi zambiri imakhala ndi ziyembekezo zolimba za protocol kuposa BMS. Tsekani inverter, kenako onetsetsani kuti BMS ikugwirizana nayo — osati mosiyana.
• Funsani wogulitsa BMS kuti akupatseni mndandanda wa ma protocol a inverter omwe amagwiritsidwa ntchito pamlingo wa firmware, ndi dzina.Mndandanda weniweni udzatchula ma protocol enaake. Yankho losamveka bwino la "imathandizira ma inverter onse akuluakulu" ndi chizindikiro chofiira chomwe chiyenera kuganiziridwa mozama.
• Pemphani chikalata cha protocol kapena mawu otsimikizira kuyanjana kwa chipangizo chanu cha inverter.Wogulitsa wodalirika angatsimikizire kuti zikugwirizana kapena kukhala woona mtima kuti ntchito yosinthira ikufunika.
• Ngati mtundu wa inverter ndi wa m'deralo kapena watulutsidwa posachedwapa,kuyembekezera kufunikira chithandizo chokhazikika osati chokhazikika, komanso nthawi yogwiritsira ntchito bajeti moyenera.
• Pa mapulojekiti a ma inverter ambiri (monga wopanga mapaketi omwe amapereka ku mitundu ingapo ya ma inverter),Sankhani BMS yokhala ndi chithandizo cha upper-monitor chomwe chingakonzedwe m'malo mwa BMS yomwe imatseka protocol imodzi ku fakitale.
