Indlela yokukhetha i-BMS yebhetri yendlu yeMarine Lithium

Qala ngoMthwalo weMarine House-Bank, Hayi Uhlobo lweSikhephe

Ibhetri yendlu yolwandle inokubonelela ngokukhanyisa, ifriji, izixhobo ze-elektroniki zokuhamba, iimpompo, izixhobo zonxibelelwano kunye nezixhobo ezisebenzisa i-inverter. Ngenxa yokuba imithwalo emininzi inokusebenza ngaxeshanye, ukhetho lwe-BMS kufuneka luqale ngoqwalaselo lwebhetri yokwenyani kunye nemfuno yombane ekwibhodi endaweni yohlobo lwesikhephe, umthamo webhetri okanye ilebhile yevolthi eqhelekileyo yodwa.

Esi sikhokelo sigxile kubhanki yasekhaya. Iibhetri eziqala injini zineprofayili eyahlukileyo yomsebenzi wamandla aphezulu okwethutyana elifutshane kwaye kufuneka zihlolwe ngokwahlukeneyo.

1. Qinisekisa ukuCwangciswa kweBhetri

Ngaphambi kokuba ukhethe i-BMS, qinisekisa ikhemistri yebhetri kunye nenani elichanekileyo leeseli ezidityanisiweyo kuthotho (ubalo lwe-S). I-voltage eqingqiweyo yindawo yokuqala kuphela; i-BMS kufuneka ihambelane nekhemistri yeseli yokwenyani kunye noqwalaselo lwepakethi.

• Ikhemistri yebhetri
• Ubalo oluchanekileyo lweeseli zochungechunge (ubalo lwe-S)
• I-voltage yebhetri eqhelekileyo
• Umthamo webhetri
• Umbane omkhulu wokutshaja
• Indawo yokufakelwa

Umzekelo, ilebheli yevolthi efana nethi “48 V” ayichazi ngokwayo inani elichanekileyo lothotho. Sebenzisa uyilo lwepakethi okanye iinkcukacha zebhetri ukuqinisekisa uqwalaselo lweseli ngaphambi kokukhetha i-BMS.

2. Yenza ubungakanani beBMS ukusuka kwiReal Onboard Current

Umthamo webhetri kwiiyure ze-amp (Ah) awuchazi ngokwawo umlinganiselo wamandla e-BMS. Kwibhanki yendlu yolwandle, chonga izixhobo ezitsala amandla ebhetri uze ubone ukuba zeziphi imithwalo enokusebenza ngaxeshanye.

• I-inverter eqhubekayo ye-DC yokufaka yangoku
• Ukunyuka kwangoku kwe-inverter kunye nobude bexesha lokunyuka
• Ifriji kunye neempompo
• Ukuhamba, unxibelelwano kunye nezinye izixhobo ze-elektroniki ze-DC
• Eminye imithwalo encedisayo enokusebenza ngaxeshanye

Jonga umbane olindelekileyo kwicala lebhetri phantsi kweemeko zokusebenza ezicwangcisiweyo. Vavanya iimfuno zokunyuka kwexesha elifutshane ngokwahlukeneyo ukuze i-inverter yexeshana okanye ukunyuka komthwalo kungadibani nomlinganiselo we-BMS oqhubekayo ofunekayo.

3. Jonga imithombo yokutshaja kunye nombane ophezulu wokutshaja

I-BMS ikwafanele ilingane necala lokutshaja lenkqubo yebhetri. Nika amandla okutshaja aphezulu avela kwizixhobo zokutshaja ezifakwe kwinqanawa.

• Itshaja ye-Alternator okanye ye-DC-DC
• Itshaja yonxweme
• Isilawuli setshaja yelanga
• Ezinye izixhobo zokutshaja ezikwibhodi

Ukuba imithombo yokutshaja engaphezulu kwenye inokusebenza ngaxeshanye, faka imeko yokutshaja edibeneyo enokubakho kuphononongo lwenkqubo. Useto lwetshaja kufuneka lufaneleke kwikhemistri yebhetri kunye nevolthi yepakethi.

4. Qinisekisa iiMfuno zoNxibelelwano

Ukuba idatha yebhetri kufuneka itshintshiswe ngesibonisi, i-inverter, itshaja okanye ezinye izixhobo ezikwibhodi, nika uphawu lwesixhobo kunye nomzekelo kunye nolwazi okanye imisebenzi yokulawula ekufuneka itshintshiswe.

I-interface ye-CAN yodwa ayiqinisekisi ukuba iyahambelana nesixhobo esithile solwandle. I-interface ebonakalayo, i-protocol, imiyalezo efunekayo kunye nemephu yedatha zonke kufuneka zihambelane nezixhobo ekujoliswe kuzo.

I-NMEA 2000 ngumgangatho wonxibelelwano lwaselwandle osekelwe kwi-CAN. Imiyalezo yayo yenethiwekhi ihlelwe njengeParameter Group Numbers (PGNs). Ukuba kufuneka udibaniso lwe-NMEA 2000, qinisekisa izixhobo ekujoliswe kuzo kunye neePGN ezifunekayo ngaphambi kokuba uvelise.

I-NMEA ikwathi iimveliso ezifunda okanye ezithumela ulwazi lwe-NMEA 2000 kufuneka ziqinisekiswe yi-NMEA. Ke ngoko, ukulungiswa kweprotocol ethile yeprojekthi kunye nebango lokuba imveliso ethile "iqinisekiswe yi-NMEA 2000" akufuneki zithathwe njengengxelo efanayo ngaphandle kokuba isiqinisekiso semveliso esichanekileyo siqinisekisiwe.

5. Jonga imeko-bume yoFakelo lwaseLwandle

Ukusebenza kokusingqongileyo kwenkqubo yebhetri yolwandle kuxhomekeke ekufakweni ngokupheleleyo, kungekhona kwi-BMS yodwa. Ngaphambi kokukhetha, chaza iimeko ezijikeleze ibhetri kunye ne-BMS.

• Ubushushu obulindelekileyo
• Ukufuma kunye nokuvezwa komswakama
• Amathuba okungena kwamanzi
• Iimeko zokungcangcazela
• Icebo lokuvala ibhetri kunye nokuvala
• Ukhuselo lwe-Connector kunye ne-terminal
• Umoya ongenisayo kunye neemeko zobushushu

Ukuba iprojekthi ifuna ukhuseleko oluthile lokungena, umlinganiselo wobushushu okanye wokungcangcazela, cela amaxwebhu eBMS echanekileyo okanye inkqubo yebhetri egqityiweyo. Musa ukugqiba kwelokuba iBMS ayinamanzi kuba nje iza kusetyenziswa kwisikhephe okanye kwisikhephe.

6. Ukuba iipakethi ezininzi zeBhetri yeNdlu ziya kudityaniswa ngaxeshanye

Iinkqubo zebhetri zasekhaya ezihambelanayo zifuna ukujongwa okongeziweyo. Iipakethi eziqhagamshelwe kwibhasi eqhelekileyo yeDC zisenokungabelani ngombane ngokulinganayo ukuba imeko yazo yokutshaja, ukumelana kwangaphakathi, ukumelana neentambo okanye iimeko zoqhagamshelo zahlukile.

• Inani leebhetri
• Ikhemistri, inani le-S kunye nomthamo wepakethi nganye
• Umlinganiselo oqhubekayo olindelekileyo kunye nomlinganiselo ophezulu wephekhi nganye
• Uyilo loqhagamshelwano olucwangcisiweyo oluhambelanayo
• Iimeko zeVolthi ngaphambi koqhagamshelo
• Icebo lokudibanisa nokuqhawula
• Unxibelelwano olufunekayo phakathi kweepakethi nezinye izixhobo

Musa ukucinga ukuba iipakethi zebhetri ze-lithium ezizimeleyo zinokuqhagamshelwa ngaxeshanye kuba i-voltage yazo eqhelekileyo iyafana. Qinisekisa ukuba uqwalaselo oluchanekileyo lwe-BMS kunye noyilo olupheleleyo lwebhetri luxhasa umsebenzi ocwangcisiweyo ohambelanayo ngaphambi koqhagamshelo.

7. Yintoni omawuyithumele kwi-DALY ukuze ufumane ingcebiso ye-BMS yendlu yolwandle-yebhetri

Thumela ulwazi olulandelayo lweprojekthi ukuze ingcebiso idibaniswe nesixhobo sokwenyani senqanawa kunye nebhetri:

Ngale mibono, iDALY ingaphonononga iimfuno zeprojekthi, ichonge iindlela ezifanelekileyo zeBMS ezikhoyo, iqinisekise iimfuno zonxibelelwano kwaye inike ulwazi olufanelekileyo lwemveliso kunye nesicatshulwa. Ukukhethwa komzekelo wokugqibela kufuneka kusekelwe kwiiparameter zeprojekthi eziqinisekisiweyo kunye namaxwebhu oqwalaselo oluchanekileyo lweBMS.

Imibuzo ebuzwa qho

Q1Ndingakhetha i-BMS yendlu yolwandle ngokwebhetri kuphela?

Hayi. Umthamo webhetri kwireyithingi yangoku ye-Ah kunye ne-BMS ziiparameter ezahlukeneyo. Qinisekisa ukuba ibhetri iyaqhubeka na, iimfuno zokunyuka kwexesha elifutshane kunye nomsinga wokutshaja.

Q2Ngaba i-BMS enye ingagubungela ngokuzenzekelayo zombini ibhanki yendlu kunye nokuqalisa injini?

Musa ukucinga njalo. Ibhenki yendlu kunye nebhetri yokuqalisa injini zineprofayili ezahlukeneyo zomthwalo. Ukuqala injini kufuneka kujongwe ngokwahlukeneyo ngokuchasene nevolthi yokuqalisa, umsinga we-cranking, ubude bomsinga kunye neenkcukacha ze-BMS ezichanekileyo.

Q3Ngaba i-CAN port ithetha ukuba i-BMS iya kusebenza nayo yonke isixhobo se-NMEA 2000?

Hayi. Ujongano, iprotocol, ii-PGN ezifunekayo kunye nomephu wedatha kufuneka zihambelane nezixhobo ekujoliswe kuzo. Amabango okuqinisekiswa kwemveliso nawo kufuneka aqinisekiswe kwisixhobo esichanekileyo.

Q4Ngaba i-BMS yolwandle ayingeni manzi ngokuzenzekelayo?

Hayi. Jonga umlinganiselo obhaliweyo wokhuseleko lokusingqongileyo okanye lokungena kwemveliso ukuze ufumane imveliso echanekileyo. Ukuvalwa kunye nokufakelwa kwebhetri epheleleyo nako kunegalelo ekukhuselweni kokusingqongileyo.

Q5Ngaba iipakethe ezininzi zebhetri yendlu ye-lithium zinokudityaniswa ngaxeshanye?

Ayikuko nje kuphela ukuba zine-voltage efanayo. Qinisekisa ukuhambelana kwepakethi, iimeko ze-voltage, ukwabelana ngoku, ukhuseleko, ukufakelwa kweentambo kunye nokuba ulwakhiwo oluchanekileyo lwe-BMS/system luyayixhasa na uyilo olucwangcisiweyo oluhambelanayo.

Malunga neDALY

I-DALY iyila kwaye ivelise iinkqubo zolawulo lwebhetri ye-lithium kwii-OEM, abavelisi beepakethi zebhetri kunye nabahlanganisi beenkqubo. Kwiiprojekthi zebhetri yendlu yaselwandle, i-BMS ecetyiswayo kufuneka ikhethwe kwisimo sebhetri yokwenyani, umthwalo wombane, inkqubo yokutshaja, iimfuno zonxibelelwano kunye neemeko zokufakela endaweni yegama lesicelo kuphela.

Cela uHlolo loKhetho lweBMS lweMarine House-Battery

Thumela ibhetri yakho, umthwalo, ukutshaja, ipakethi ehambelanayo, ulwazi lokusingqongileyo kunye nonxibelelwano kwi-DALY. Iqela lobuchwephesha lingajonga iimfuno kwaye linikeze isindululo sokukhetha i-BMS, amaxwebhu emveliso afanelekileyo kunye nekowuteshini.
