Ukubuka Konke Komhlahlandlela

Uma wakha ibhethri lesithuthuthu sikagesi emakethe yaseNdiya, ukukhetha i-BMS kufanele kuqale ngezidingo zesistimu yebhethri kanye nesilawuli kunelebula yamandla emoto kuphela. Qinisekisa ikhemikhali yebhethri kanye nenani eliqondile lamaseli ochungechunge, ukuqhubeka kwebhethri ohlangothini kanye nogesi ophezulu, izimo zokusebenza, kanye nanoma yikuphi ukuxhumana okudingekayo nesilawuli noma ideshibhodi.

Kumaphrojekthi angaphakathi kobubanzi be-AIS-156, imisebenzi yokuphepha ye-BMS kanye nezidingo zokugunyazwa ze-Rechargeable Electrical Energy Storage System (REESS) ephelele kumele nazo zicatshangelwe. Ukukhetha i-BMS kukodwa akwenzi uhlelo lwebhethri oluphelele lwe-AIS-156 luhambisane.

1. Qala nge-Battery Chemistry kanye ne-Exact S Count

Ngaphambi kokuqhathanisa izilinganiso zamanje ze-BMS, qinisekisa i-chemistry yebhethri, inani eliqondile lamaseli axhunyiwe ochungechungeni (inani le-S), i-voltage yephakethe elijwayelekile kanye nemikhawulo yokushaja. I-LiFePO4, i-NCM/Li-ion kanye nezinye i-lithium chemistry zisebenzisa ububanzi obuhlukene bama-voltage eseli, ngakho-ke i-BMS kumele ifane nomklamo webhethri wangempela.

Ungaqageli inani eliqondile lika-S kusukela kulebula ye-pack-voltage eqanjiwe kuphela. Sebenzisa umklamo we-battery-pack noma imininingwane yeseli njengereferensi yokugcina.

2. Usayizi we-BMS usebenzisa i-Battery-Side Current, hhayi i-Motor Power kuphela

Amandla enjini awusizo ngolwazi lwangemuva, kodwa awanqumi ngokuhlukile isilinganiso samanje se-BMS. I-BMS ibona amandla aseceleni kwebhethri, nawo athintwa yi-pack voltage, umkhawulo wamanje webhethri wesilawuli, isidingo sokusheshisa, isisindo semoto, ama-gradients, izimo ze-drivetrain kanye nokushisa kokusebenza.

Ngaphambi kokukhetha izinga lamanje le-BMS, qinisekisa:

• Ibhethri eliqhubekayo elilindelekile
• Umkhawulo wamanje webhethri ohlangothini lwesilawuli
• Ibhethri lamanje eliphakeme kakhulu
• Ubude besikhathi samandla aphezulu kanye nemvamisa yokuphindaphinda
• Umthamo wokushaja ovuselelayo ophezulu, uma kusetshenziswa ibhuleki elivuselelayo

3. Hlola i-Continuous Current kanye ne-Peak Current ngokwehlukana

Umthamo wamandla oqhubekayo kanye nomthamo wamandla ophakeme wesikhathi esifushane kuyizidingo ezahlukene. I-BMS ehlangabezana nomsinga ojwayelekile wokugibela isadinga ukuhlolwa ngokumelene nokusheshisa, ukukhuphuka kanye nezinye iziqongo zesikhathi esifushane.

Uma ucela isincomo, nikeza kokubili ugesi ophezulu kanye nokuthi uhlala isikhathi esingakanani. Ungavumi i-BMS kuphela ngoba isilinganiso sayo sogesi oqhubekayo sibonakala siseduze nomthwalo olindelekile.

4. Qinisekisa Ukuxhumana Komlawuli Nedeshibhodi

Uma i-BMS idinga ukuxhumana nomlawuli wesithuthuthu, ideshibhodi noma enye iyunithi yokulawula kagesi, nikeza imodeli yemishini kanye nenqubo yokuxhumana edingekayo.

I-Controller Area Network (CAN), i-RS485 kanye ne-UART zichaza izixhumi zokuxhumana. Ukuba nesixhumi esifanayo akusho ngokuzenzakalelayo ukuthi amadivayisi amabili angashintshana ngemiyalezo edingekayo. Iphrothokholi kanye nokumapha idatha kumele futhi kufane nemishini eqondiwe.

5. Okushiwo yi-AIS-156 ekukhethweni kwe-BMS

I-AIS-156 ibeka izidingo zokuphepha ze-Rechargeable Electrical Energy Storage Systems (REESS) ezisetshenziswa ezimotweni zikagesi zesigaba se-L, kufaka phakathi izimoto zikagesi ezinamasondo amabili. I-BMS ingenye ye-REESS ephelele ehlolwe ngaphakathi kwenqubo yokuvunyelwa kwemoto.

Isichibiyelo se-AIS-156 3 sichaza i-BMS esekelwe ku-microprocessor noma i-microcontroller futhi sikhomba imisebenzi yokuphepha eqinisekiswa ngesikhathi sokuhlolwa kwe-REESS, kufaka phakathi i-over-voltage, i-over-charge, i-over-discharge, i-over-temperature, i-overcurrent kanye ne-short-circuit. Izidingo zokuhambisana kwe-electromagnetic (EMC) ezisebenzayo nazo zidinga ukucatshangelwa.

6. Qondanisa Imfuneko Eqinisekisiwe ne-DALY A-Series Smart BMS

I-DALY A-Series Smart BMS inikeza amazinga amaningana aqinisekisiwe okushisa okuqhubekayo. Sebenzisa lawa njengamazinga afanele kuphela ngemva kokuba izidingo zephrojekthi ezingenhla seziqinisekisiwe. Akuzona izincomo eziqinile zokusuka esithuthuthu uye kwimodeli.

Umngcele womkhiqizo: izinga lamanje lodwa alanele. Ukukhetha kokugcina kusadinga i-chemistry yebhethri eqondile, inani le-S, amandla aqhubekayo kanye ne-peak, izimo zokushisa, izidingo zomlawuli kanye nezidingo zokuxhumana.

7. Okufanele Ukuthumele ku-DALY ukuze Kukhethwe i-BMS

Ukuze uthole isincomo se-BMS esiqondene nephrojekthi ethile, thumela ulwazi olulandelayo:

• Uhlobo lwemoto kanye nesicelo esihlosiwe
• I-chemistry yebhethri kanye nenani eliqondile le-S
• I-voltage yephakethe elijwayelekile kanye nomthamo
• Ibhethri eliqhubekayo elilindelekile
• Uhlobo/imodeli yomlawuli kanye nogesi ophezulu ohlangothini lwebhethri
• Isikhathi esiphezulu samanje, ubude besikhathi kanye nemvamisa yokuphindaphinda
• Umthamo wokushaja ovuselelayo ophezulu, uma kusebenza
• Izinga lokushisa eliphezulu kanye nezimo zokuvalwa kwebhethri
• Izidingo zokuxhumana zesilawuli/ideshibhodi
• Uhlobo lwesibonelo, umshayeli noma inani lokukhiqiza

Ngalezi zinto ezifakiwe, i-DALY ingabuyekeza izinketho ezifanele ze-A-Series, iqinisekise ukucushwa kwamanje nokuxhumana okudingekayo, futhi inikeze imininingwane yomkhiqizo efanele kanye nesilinganiso.

imibuzo ejwayelekile ukubuzwa

Q1Ngingakhetha i-BMS kumandla enjini kuphela?

Cha. Amandla enjini angukufakwa okukodwa kuphela. Qinisekisa ukuthi ibhethri lingakanani isilawuli, ibhethri eliqhubekayo elilindelekile, ibhethri eliphakeme kanye nobude besikhathi, i-voltage yephakethe kanye nezimo zokusebenza.
