Itumanaho rya BMS ryo guhuza ububiko bw'izuba: Guhuza CAN, RS485, na Inverter Protocole

Impamvu itumanaho rya Inverter ari ryo rya mbere ryangiritse mu bubiko bw'izuba

Vugana n'umuntu wese wategetse ko imirasire y'izuba ibikwa ku gipimo cy'ubushyuhe, uzumva inkuru nk'iyi: ipaki yatsinze ikizamini cyose ku ntebe. Umuvuduko w'uturemangingo mu buryo bugaragara, kuringaniza imikorere, uburinzi burasa nk'uko byari byitezwe. Hanyuma aho hantu, inverter na bateri byanze kuvugana - cyangwa se bibi kurushaho, bavuganye, ariko batangaje imiterere itari yo y'imashini, banze amabwiriza yo gushyushya, cyangwa bateranye kode z'amakosa nta muntu washoboraga kuzisobanura. Ipaki yagarutse mu rugo. Umushinga watakaje icyumweru kimwe.

Iyi si ingero idasanzwe. Ni imwe mu ngorane zikunze kugaragara mu mishinga yo kubika imirasire y'izuba, kandi hafi ya buri gihe impamvu nyamukuru iba imwe: BMS ifite icyambu cya CAN, ariko mu by'ukuri ntivuga ku buryo inverter yiteze. Ku bijyanye no kubika, itumanaho si ikintu cy'ingenzi - ni umusingi sisitemu ihagazeho.

Imiyoboro Itatu — Icyo Buri Imwe Ikora Mu By'ukuri Muri Sisitemu Yo Kubika

Ubusanzwe, itumanaho rya BMS rikoresha imiyoboro itatu ifatika, buri imwe ifite imiterere itandukanye y'urujya n'uruza rw'abantu. Kumenya umuyoboro ugenzura intambwe ya mbere mu kwandika ibisobanuro by'ingirakamaro by'itumanaho:

Bisi ya CAN

Isano ry’ingenzi cyane hagati ya bateri na inverter mu gihe nyacyo. CAN ifite imipaka yo gushyushya, imipaka yo gushyushya no gusohora umuriro, imipaka y’amashanyarazi, ibimenyetso by’ikosa, n’ubutumwa bwo kugenzura porotolike. Iyi ni yo nzira inverter ikoresha kugira ngo imenye uburyo bwo gushyushya no gusohora bateri mu buryo butekanye. Iyo CAN inaniwe cyangwa ivuze porotoli itari yo, igice gisigaye cya sisitemu nta kintu na kimwe gishobora gukoreshwa.

RS485

Ikoreshwa mu kugenzura buhoro buhoro, telemetry, no guhuza na sisitemu zo gucunga ingufu ku rwego rw'urubuga cyangwa porogaramu yo kugenzura hejuru. RS485 kandi ni uburyo busanzwe bwo gukoresha sisitemu nyinshi zifatanye na daisy aho buri paki itanga raporo ku mugenzuzi. Modbus RTU ni yo porotoli isanzwe kuri iyi link.

Bluetooth

Ku bijyanye no gusuzuma abakoresha ba installer n'abakoresha ba nyuma — porogaramu ya terefone igendanwa igaragaza voltages za selile, ubushyuhe, imiterere yo kuringaniza, n'amateka y'ibiza. Ntabwo ari igice cy'umurongo w'igenzura uhoraho; ni ingirakamaro mu gushyiraho, gukemura ibibazo, no gukorera mu mucyo abakoresha ba nyuma.

Itandukaniro Rikomeye: Kugira CAN Ntibisobanura Kuvuga Porotokole ya Inverter Yawe

Iki gice gikwiye kugabanya umuvuduko, kuko niho kugura ibintu byinshi bitagenda neza. CAN bus ni igipimo ngenderwaho n'amashanyarazi - uburyo bwo kwimura ibice hagati y'ibikoresho mu buryo bwizewe. Si protocole. Protocole ni amasezerano yerekeye icyo ibyo bice bisobanura: ni iyihe ID y'ubutumwa ifite imiterere y'ifaranga, imiterere ya byte ihagarariye umupaka w'ifaranga, ni iyihe kode y'ikosa igenwa.

Ibice bibiri bya BMS bishobora "gushyigikira CAN" kandi ntibishobore kuvugana na inverter imwe, kuko bishyiraho protocole zitandukanye. BMS ishyigikira interface ya CAN rusange ariko idashyira mu bikorwa imiterere y'ubutumwa inverter iteganya ko izatanga neza ikibazo cyavuzwe haruguru: insinga zirahujwe, amatara aracanye, kandi nta kintu cy'ingirakamaro gihindurwa.

Amaporotoli ya Common Storage Inverter, n'icyo Inkunga y'umwimerere isobanura mu by'ukuri

Ku isi yose, ububiko bw’amazu n’ubw’ubucuruzi buciriritse bwahujwe ku buryo buto bw’amabwiriza ya inverter. Urutonde nyarwo umushinga ukeneye ruterwa n’uburyo inverter yagenwe, ariko ikiganiro gikunze kugaragara ku bicuruzwa bikomeye bikorera buri isoko ry’akarere. Munsi y’urwego rw’ikirango, hari imiterere ibiri ifatika yo gusobanukirwa:

Inkunga ya porotokole kavukire

Firmware ya BMS ishyira mu bikorwa protocole ya inverter mu buryo butaziguye. Kenshi na kenshi, gukoresha protocole biroroha cyane kuko protocole yamaze gushyirwa mu bikorwa ku rwego rwa firmware - nubwo ibintu byihariye nka verisiyo ya protocole, verisiyo ya firmware ku mpande zombi, parameter mapping, na inverter-side configuration biracyakeneye kwemezwa neza kugira ngo hamenyekane neza uko byakoreshejwe. Ibi nibyo bigabanya ibibazo byo mu kibuga ugereranyije n'inzira ishobora guhindurwa cyangwa CAN-only, aho urwego rwa protocole ubwarwo rugomba gutegurwa cyangwa guhindurwa hamwe n'ibyo byose byavuzwe haruguru.

Ubufasha bushobora gutegurwa / bushobora guhinduka

BMS itanga CAN na upper-monitor configuration interface ituma protocole itoranywa cyangwa igahuzwa na inverter runaka. Ibi biroroshye ariko bisaba ko installer cyangwa sosiyete ibikora cyangwa ikabitanga imenya icyo bakora mu gihe cyo kuyikoresha.

Interineti ya CAN gusa

BMS ifite umuyoboro wa CAN ariko ntabwo ishyira mu bikorwa protocole ya inverter. Integrator yitezweho guteza imbere urwego rwa protocole ubwayo. Ku mishinga myinshi yo kubika ibi ntabwo ari ingirakamaro mu bucuruzi - igihe cy'ubuhanga gitwara amafaranga menshi kuruta guhitamo BMS ifite ubufasha bw'umwimerere.

Ikibazo cy'ukuri ku bijyanye n'ububiko ubwo aribwo bwose: urashaka ko porogaramu ikoreshwa mu buryo bwa gakondo, ishobora guhindurwa, cyangwa ugiye kubaka urwego rwa protocole? Abakora porogaramu benshi bashaka porogaramu ikoreshwa mu buryo bwa gakondo. Abakora porogaramu zikora imishinga myinshi mu bicuruzwa bitandukanye bya inverter akenshi bashaka ko porogaramu ikoreshwa mu buryo bwa gakondo.

Uburyo bwo kugenzura ko bihuye mbere yo gutumiza

Uru ni urutonde rw'ibintu bigomba gukorwa mbere ya RFQ birinda ko ikibazo cyo kubura aho giherereye cyavuzwe mu ntangiriro. Kubikoraho bifata igihe kitarenze isaha imwe, kandi bikagabanya ibyumweru nyuma y'aho:

• Emeza icyerekezo cyawe cya inverter mbere na mbere, ntabwo ari BMS.Inverter ubusanzwe iba ifite gahunda ikomeye kurusha BMS. Funga inverter, hanyuma urebe neza ko BMS ihuye nayo — ntabwo ari ko bimeze ukundi.
• Baza umucuruzi wa BMS urutonde rwa protocole za inverter zikoreshwa mu buryo bw'umwimerere ku rwego rwa firmware, ukurikije izina.Urutonde nyarwo ruzavuga porotokoli runaka. Igisubizo kidasobanutse neza cya "ishyigikira inverters zose zikomeye" ni ikimenyetso cy'ingenzi gikwiye gufatwa nk'ikintu gikomeye.
• Saba inyandiko ya protocole cyangwa icyemezo cyo kugenzura imikoranire yabyo byihariye kuri inverter yawe.Umutanga serivisi w’ingenzi azabyemeza cyangwa abe inyangamugayo ko hakenewe akazi ko guhindura imiterere y’ibikoresho.
• Niba ikirango cya inverter ari icy'akarere cyangwa giherutse gusohoka,kwitega ko hakenewe ubufasha bushobora guhindurwa aho kuba ubufasha gakondo, no gukoresha ingengo y'imari mu gihe gikwiye.
• Ku mishinga ya "multi-inverter" (urugero: uruganda rukora paki rutanga ibikoresho byinshi bya "inverter"),ukunda BMS ifite igikoresho cyo hejuru gishobora guhindurwa kuruta BMS ifunga protocole imwe mu ruganda.

Itsinda ry'itumanaho rya DALY ryo kubika imirasire y'izuba

BMS yo kubika ingufu ya DALY yubatswe hakurikijwe imiterere y'itumanaho yavuzwe haruguru. Itanga CAN bus na RS485 kugira ngo ihuzwe na inverter na sisitemu zo ku rwego rw'aho ikorera, hamwe n'ibimenyetso by'itumanaho byoroshye kugira ngo hashyirweho interlocks zo ku rwego rw'ibikoresho. Ku rwego rwa protocole, protocole za inverter zo kubika zikoreshwa mu buryo bwa gakondo ku rwego rwa firmware ku bigo bikomeye bikorera isoko ry'ububiko bw'amazu n'ubw'ubucuruzi buto; ku bigo bya inverter bitari ku rutonde rw'aho ikorera, imiterere ya monitor yo hejuru yemerera protocole kwihutisha umushinga mu gihe cyo gutangira.

Ibintu bibiri by'ingenzi muri iyi ngingo: urutonde nyarwo rw'ibirango bya inverter bishyigikiwe n'umwimerere ni ikintu cyo gusaba itsinda ry'abahanga mu by'ubwubatsi ku mushinga wawe wihariye, ntabwo ari ikintu cyo gutekereza mu rurimi rw'ubucuruzi rusange; kandi "ubufasha gakondo" mu rupapuro rw'amakuru rw'umucuruzi uwo ari we wese bugomba kwemezwa buri gihe ukurikije icyitegererezo cyawe nyacyo cya inverter mbere yuko utumiza.

Ibibazo Bikunze Kubazwa

Q1Niba BMS spec ivuga ngo "CAN ishyigikiwe," ese ibyo birahagije kugira ngo ububiko bube bwiza?

Ntabwo ari ubwabyo. "Can supported" ikubwira ko BMS ifite aho ihurira na CAN kandi ishobora kwimura ibice muri bisi; ntabwo ikubwira ko BMS ivuga protocole nk'uko inverter yawe yiteze. Mbere yo gutangira, baza protocole za inverter zishyirwa mu bikorwa mu buryo bw'umwimerere ku rwego rwa firmware. Niba icyo kibazo kibonye igisubizo kidasobanutse neza, ayo niyo makuru wari ukeneye mbere yo gutanga commande.

Q2Ni irihe tandukaniro riri hagati yo gushyigikira protocole gakondo no gushyigikira CAN gusa?

CAN ni igipimo ngenderwaho cy’itumanaho n’itumanaho ry’ubutumwa; protocol ni amasezerano y’ubutumwa n’ibirimo. Inkunga ya protocole karemano bivuze ko firmware ya BMS ishyira mu bikorwa imiterere y’ubutumwa runaka ikirango cya inverter cyiteze, bityo ibyo bikoresho byombi bikorana neza bivuye mu gasanduku. Inkunga ya CAN gusa bivuze ko BMS ifite umuyoboro ariko integrator igomba guteza imbere urwego rwa protocole kugira ngo ikore - ibyo bikaba bidakunze kugurishwa mu mishinga yo kubika amakuru.

Q3Ni gute nakora umushinga wa multi-inverter aho ntanga ubwoko butandukanye bwa inverter?

Shaka BMS ifite porotokeri ishobora guhindurwa ukoresheje igikoresho cya "upper-monitor" cyangwa firmware, aho gukoresha BMS ishyiraho porotokeri imwe ya inverter mu ruganda. Ibi bituma ibikoresho bimwe bya BMS byoherezwa ku bicuruzwa byinshi bya inverter hamwe n'uburyo bwo guhindura porotokeri mu gihe cyo gutangira gukora. Emeza n'umutanga serivisi ibirango biri mu bubiko bwa porotokeri ishobora guhindurwa kandi bikenewe gukorwa mu buryo bwihariye.

Ku bijyanye na DALY

DALY ikora sisitemu zo gucunga bateri za lithiamu ku bigo bitanga serivisi, abakora paki, n'abahuza, hamwe n'ibicuruzwa bikoreshwa mu bihugu birenga 130. DALY yashinzwe mu 2015, ikora hakurikijwe sisitemu za ISO 9001 / ISO 14001 zikurikiza amategeko ya CE na RoHS; umurongo wo kubika ingufu ufite sitati ya UL Recognised Component (ntabwo ari icyemezo cyuzuye cya sisitemu ya UL - itandukaniro ni ingenzi ku mishinga yo muri Amerika y'Amajyaruguru), hamwe n'inyandiko zitangwa kugira ngo zishyigikire icyemezo cy'urwego rwa sisitemu ku rwego rwa paki cyangwa sisitemu.

Urashaka kuvuga BMS Communication kuri Project yawe yo kubika?

Niba urimo ushakisha umushinga wo kubika imirasire y'izuba kandi ukaba wifuza ko itumanaho rya BMS-inverter rikora koko aho rikorera, itsinda ry'abahanga rya DALY rishobora kwemeza ko protocole ihuye na model yawe ya inverter mbere yuko commande isohoka.
