Ukuxhumana kwe-BMS kokuhlanganiswa kwesitoreji selanga: Ukuhambisana kwe-CAN, RS485, kanye ne-Inverter Protocol

Kungani Ukuxhumana Kwe-Inverter Kuyiyona Nqaba Yokuhluleka Kwensimu Enkulu Ekwakhiweni Kwesitoreji Selanga

Khuluma nanoma ubani oye wayala isitoreji selanga ngobukhulu futhi uzozwa inguqulo yendaba efanayo: iphakethe liphumelele zonke izivivinyo ebhentshini. Ama-voltage eseli ngaphakathi kwe-spec, ukulinganisela kusebenza, ukuvikelwa kuqhuma njengoba bekulindelekile. Bese kuthi endaweni, i-inverter nebhethri benqabe ukukhuluma — noma okubi nakakhulu, bakhulume, kodwa babike isimo sokushaja esingalungile, benqaba imiyalo yokushaja, noma baphonsa amakhodi amaphutha akekho owayengakwazi ukuwachaza. Iphakethe libuyele ekhaya. Iphrojekthi ilahlekelwe isonto lonke.

Lokhu akuyona into engavamile. Kungenye yezinkinga ezivame kakhulu emkhakheni wezinhlelo zokugcina amandla elanga, futhi cishe njalo imbangela eyinhloko iyafana: i-BMS enechweba le-CAN, kodwa empeleni ayikhulumi ngenqubo elindelwe yi-inverter. Ngokuqondene nesitoreji, ukuxhumana akuyona into ebalulekile - kuyisisekelo uhlelo olumi kuso.

Iziteshi Ezintathu — Lokho Ngayinye Ekwenzayo Empeleni Kuhlelo Lokugcina Isitoreji

Ukuxhumana kwe-BMS yesitoreji selanga ngokuvamile kusebenzisa iziteshi ezintathu ezibonakalayo, ngayinye iphethe iphethini ehlukile yethrafikhi. Ukwazi ukuthi yisiphi isiteshi esiphatha isinyathelo sokuqala sokubhala imininingwane yokuxhumana ewusizo:

Ibhasi le-CAN

Isixhumanisi sesikhathi sangempela esibaluleke kakhulu phakathi kwebhethri ne-inverter. I-CAN ithwala imikhawulo yamanje yokushaja, ukushaja nokukhipha amandla, imikhawulo yamandla kagesi, amafulegi amaphutha, kanye nemiyalezo yokulawula ethize yephrothokholi. Lesi yisiteshi i-inverter ethembele kuso ukuze yazi ukuthi ingashaja kanjani futhi ikhiphe amandla ebhethri ngokuphephile. Uma i-CAN yehluleka noma ikhuluma iphrothokholi engalungile, lonke uhlelo alunalutho olungasetshenziswa.

I-RS485

Isetshenziselwa ukuqapha okuhamba kancane, i-telemetry, kanye nokuhlanganiswa nezinhlelo zokuphathwa kwamandla ezingeni lesayithi noma isofthiwe yokuqapha ephezulu. I-RS485 futhi iyi-interface evamile yezinhlelo zamaphakethe amaningi eziboshwe nge-daisy lapho iphakethe ngalinye libika khona kumlawuli. I-Modbus RTU iyiphrothokholi ejwayelekile kulesi sixhumanisi.

I-Bluetooth

Kokuxilonga komfaki kanye nomsebenzisi wokugcina — uhlelo lokusebenza lwe-smartphone olubonisa ama-voltage eseli, amazinga okushisa, isimo sokulinganisela, kanye nomlando we-alamu. Akuyona ingxenye ye-loop yokulawula ebukhoma; iwusizo ekuqaliseni, ekuxazululeni izinkinga, kanye nasekubonakaleni komsebenzisi wokugcina.

Umehluko Obalulekile: Ukuba ne-CAN Akusho Ukukhuluma Iphrothokholi Yakho Ye-Inverter

Lesi sigaba kufanele sinciphise ijubane, ngoba yilapho ukuthenga okuningi kweshidi lemininingwane kungahambi kahle khona. Ibhasi le-CAN liyindinganiso ebonakalayo nekagesi - indlela yokuhambisa ama-bits phakathi kwamadivayisi ngokuthembekile. Akuyona iphrothokholi. Amaphrothokholi ayizivumelwano mayelana nokuthi lawo ma-bits asho ukuthini: iyiphi i-ID yomlayezo ephethe isimo sokushaja, ukuthi ukwakheka kwe-byte kumelela umkhawulo wamanje wokushaja, ukuthi amakhodi amaphutha achazwayo anjani.

Amayunithi amabili e-BMS angasekela i-CAN futhi angakwazi nhlobo ukukhuluma ne-inverter efanayo, ngoba asebenzisa amaphrothokholi ahlukene. I-BMS esekela isikhombimsebenzisi se-CAN esijwayelekile kodwa engasebenzisi isakhiwo somlayezo i-inverter yakho esilindele izokhiqiza ukwehluleka kwendawo okuchazwe ngenhla: izintambo zixhunyiwe, izibani zivuliwe, futhi akukho lutho oluwusizo olushintshwayo.

Amaphrothokholi E-Common Storage Inverter, kanye Nokuthi Ukusekelwa Kwabantu Bendabuko Kusho Ukuthini Ngempela

Emhlabeni jikelele, indawo yokugcina izinto zokuhlala kanye nezebhizinisi ezincane ihlanganiswe kusethi encane yezinqubo ze-inverter. Uhlu oluqondile oludingwa yiphrojekthi luncike ekutheni iyiphi i-inverter ecacisiwe, kodwa ingxoxo ivame ukubandakanya izinhlobo ezinkulu ezikhonza imakethe ngayinye yesifunda. Ngaphansi kwezinga lomkhiqizo, kunezindlela ezimbili ezingokoqobo zokuhambisana okufanele uziqonde:

Usekelo lwephrothokholi yomdabu

I-firmware ye-BMS isebenzisa iphrothokholi ye-inverter ngqo. Ezimweni eziningi, ukuqalisa ukusebenza kuba lula kakhulu ngoba iphrothokholi isivele isetshenziswa ezingeni le-firmware — yize imininingwane efana nenguqulo yephrothokholi, inguqulo ye-firmware ezinhlangothini zombili, imephu yamapharamitha, kanye nokucushwa kwe-inverter ohlangothini kusadingeka kuqinisekiswe ukuthunyelwa okuqondile. Yilokhu okunciphisa ukwehluleka kwensimu uma kuqhathaniswa nendlela elungisekayo noma ye-CAN kuphela, lapho ungqimba lwephrothokholi ngokwalo kufanele luthuthukiswe noma lulungiswe ngaphezu kwakho konke okungenhla.

Usekelo olulungisekayo/oluguquguqukayo

I-BMS inikeza i-CAN kanye ne-upper-monitor configuration interface evumela ukuthi iphrothokholi ikhethwe noma ilungiswe ku-inverter ethile. Lokhu kuyaguquguquka kodwa kudinga ukuthi umfakisi noma umhlinzeki azi ukuthi benzani ngesikhathi sokusebenza.

Isixhumi esibonakalayo se-CAN kuphela

I-BMS inechweba le-CAN kodwa ayisebenzisi iphrothokholi ye-inverter. I-integrator kulindeleke ukuthi ithuthukise ungqimba lwephrothokholi ngokwayo. Kumaphrojekthi amaningi okugcina lokhu akusebenzi kahle kwezentengiselwano — isikhathi sobunjiniyela sibiza kakhulu kunokukhetha i-BMS ngokusekelwa kwendabuko.

Umbuzo oqotho osebenzayo wanoma iyiphi i-RFQ yesitoreji: ufuna i-native, i-configurable, noma empeleni uzokwakha ungqimba lwephrothokholi? Abafaki abaningi bafuna i-native. Abakhiqizi bephakethe abaqhuba amaphrojekthi amaningi kumikhiqizo ehlukene ye-inverter bavame ukufuna i-configurable.

Indlela Yokuqinisekisa Ukuhambisana Ngaphambi Koku-oda

Lolu uhlu lokuhlola lwangaphambi kwe-RFQ oluvimbela ukwehluleka kwendawo okuchazwe ekuqaleni. Ukusebenza ngalo kuthatha isikhathi esingaphansi kwehora, futhi konga amasonto engeziwe:

• Qinisekisa imodeli yakho ye-inverter kuqala, hhayi i-BMS.I-inverter ivame ukuba nokulindela okuqinile kwephrothokholi kune-BMS. Khiya i-inverter, bese uqinisekisa ukuthi i-BMS iyayifanela — hhayi okuphambene nalokho.
• Cela umhlinzeki we-BMS uhlu lwezinqubo ze-inverter ezisetshenziswa ngokwemvelo ezingeni le-firmware, ngegama.Uhlu lwangempela luzosho amaphrothokholi athile. Impendulo engacacile yokuthi "isekela wonke ama-inverter amakhulu" iwuphawu olubalulekile okufanele luthathwe ngokungathi sína.
• Cela idokhumenti yephrothokholi noma isitatimende sokuqinisekisa ukuhambisana esiqondene nemodeli yakho ye-inverter.Umhlinzeki oqotho uzoqinisekisa ukuthi lokho kuyafana noma athembeke ukuthi umsebenzi wokuzivumelanisa nezimo uyadingeka.
• Uma uhlobo lwe-inverter lungolwesifunda noma lusanda kukhishwa,lindela ukudinga ukwesekwa okulungisekayo kunokuba kube okwendabuko, kanye nesikhathi sokufaka isabelomali ngokufanele.
• Kumaphrojekthi e-multi-inverter (isb. umenzi wephakethe ohlinzeka ngemikhiqizo eminingana ye-inverter),khetha i-BMS enokusekelwa kwe-upper-monitor okulungisekayo kune-BMS evala iphrothokholi eyodwa efektri.

Isitaki Sokuxhumana se-DALY Sokugcina Ilanga

I-DALY's 4th Generation Energy Storage BMS yakhelwe eduze kwephethini yokuxhumana echazwe ngenhla. Ihlinzeka ngebhasi le-CAN kanye ne-RS485 yokuhlanganiswa bukhoma nezinhlelo ze-inverter kanye nezezinga lesayithi, kanye nokuxhumana okomile kokuxhumana kwama-interlocks ezingeni lehadiwe. Esigabeni sephrothokholi, amaphrothokholi avamile e-inverter esitoreji asetshenziswa ngokwendabuko ezingeni le-firmware lemikhiqizo emikhulu ekhonza imakethe yokugcina yezindawo zokuhlala kanye neyezentengiselwano ezincane; kumabhrendi e-inverter angaphandle kohlu lwendabuko, isikhombimsebenzisi sokucushwa kwe-upper-monitor sivumela ukujwayelana kwephrothokholi ethile yephrojekthi ukuthi kuthuthukiswe ngesikhathi sokusebenza.

Izincazelo ezimbili ngokomqondo walesi sihloko: uhlu oluqondile lwemikhiqizo ye-inverter esekelwa ngokomdabu yinto ongayicela eqenjini lobunjiniyela lephrojekthi yakho ethile, hhayi into ongayicabanga ngolimi lokumaketha olujwayelekile; kanye "nokusekelwa komdabu" kunoma yiliphi ishidi ledatha lomthengisi kufanele kuqinisekiswe njalo ngokumelene nemodeli yakho ye-inverter eqondile ngaphambi kokuba kufakwe i-oda.

imibuzo ejwayelekile ukubuzwa

Q1Uma i-BMS spec ithi "I-CAN isekelwa," ingabe lokho kwanele ukwakha isitoreji?

Akuyona yodwa. I-"CAN supported" ikutshela ukuthi i-BMS inechweba le-CAN futhi ingahambisa ama-bits ebhasini; ayikutsheli ukuthi i-BMS ikhuluma ngenqubo elindelwe yi-inverter yakho ethile. Ngaphambi kokuzibophezela, buza ukuthi yiziphi izinqubo ze-inverter ezisetshenziswa ngendlela yemvelo ezingeni le-firmware. Uma lowo mbuzo uthola impendulo engacacile, yileyo idatha oyidingayo ngaphambi kokufaka i-oda.

Q2Uyini umehluko phakathi kokusekelwa kwephrothokholi yomdabu nokusekela i-CAN nje?

I-CAN iyindinganiso yokuxhumanisa kanye nokuthutha imiyalezo; iphrothokholi iyisivumelwano sokuqukethwe komlayezo. Ukusekelwa kwephrothokholi yemvelo kusho ukuthi i-firmware ye-BMS isebenzisa isakhiwo esithile somlayezo esilindelwe uhlobo oluthile lwe-inverter, ngakho-ke amadivayisi amabili axhumana kahle ngaphandle kwebhokisi. Ukusekelwa kwe-CAN kuphela kusho ukuthi i-BMS inechweba kodwa i-integrator kufanele ithuthukise ungqimba lwephrothokholi ukuze isebenze - okuyinto engavamile ukusetshenziswa kwezentengiselwano kumaphrojekthi okugcina.

Q3Ngingawusingatha kanjani umsebenzi we-multi-inverter lapho ngihlinzeka khona ngezinhlobo ezahlukene ze-inverter?

Funa i-BMS enokusekelwa kwephrothokholi elungisekayo ngethuluzi le-upper-monitor noma le-firmware, kune-BMS ebhala ikhodi yephrothokholi eyodwa ye-inverter efektri. Lokhu kuvumela ihadiwe efanayo ye-BMS ukuthi ithunyelwe kumikhiqizo eminingi ye-inverter ene-protocol adjustment ephathwa ngesikhathi sokusebenza. Qinisekisa nomhlinzeki ukuthi yimaphi amabhrendi asevele ekulabhulali yephrothokholi elungisekayo futhi adinga ukuthuthukiswa kwephrojekthi ethile.

Mayelana ne-DALY

I-DALY iklama futhi ikhiqize izinhlelo zokuphatha amabhethri e-lithium zama-OEM, abakhiqizi bamaphakethe, kanye nabahlanganisi, ngemikhiqizo esetshenziswa emazweni angaphezu kuka-130. Yasungulwa ngo-2015, i-DALY isebenza ngaphansi kwezinhlelo ze-ISO 9001 / ISO 14001 ezihambisana ne-CE kanye ne-RoHS; umugqa wokugcina amandla uphethe isimo se-UL Recognised Component (hhayi isitifiketi esigcwele sesistimu ye-UL - umehluko ubalulekile kumaphrojekthi aseNyakatho Melika), ngamadokhumenti anikeziwe ukusekela isitifiketi sezinga lesistimu ezingeni lephakethe noma lesistimu.

Ukucacisa Ukuxhumana kwe-BMS Kwephrojekthi Yakho Yokugcina Izinto?

Uma ubheka iphrojekthi yokugcina amandla elanga futhi ufuna ukuxhumana kwe-BMS-inverter kusebenze ngempela endaweni, ithimba lobunjiniyela le-DALY lingaqinisekisa ukuhambisana kwephrothokholi yemodeli yakho ye-inverter ethile ngaphambi kokuba i-oda liphume.
