I-EMU1003-Telecom Lithium LFP Ibhethri Pack BMS 50/75A
Isingeniso Somkhiqizo
(1) Ukutholwa komthamo weseli nebhethri:
Sethula umkhiqizo wethu omusha nomusha, imikhiqizo yesicelo sokusekela amandla ezokuxhumana, esetshenziswa endaweni yokusebenza yeziteshi eziyisisekelo.I-Cell Voltage Detection kanye nohlelo lwamanje lokuqapha.Le sistimu ethuthukisiwe yakhelwe ukuhlinzeka ngokutholwa kwe-voltage okunembile kanye nokuqapha ngesikhathi sangempela ukushaja kanye nokukhipha amandla kumaphakethe ebhethri.
Ngokunemba kokutholwa kwamandla kagesi okungu-±10mV ku-0-45°C kanye naku-±30mV ku--20-70°C, i-50A/75A yamanje, umkhawulo wamanje okwenziwayo, ukushaja kwangaphambili neminye imisebenzi, isistimu yethu iqinisekisa izilinganiso ezinembile nezithembekile. ngokushajwa kwebhethri nokutholwa kwamanje kokukhipha.Lokhu kunemba okuthuthukisiwe kuvumela ukuqapha okuphumelelayo nokuphumelelayo kokusebenza kwebhethri, ukuqinisekisa izinqubo zokushaja nokukhipha.
Ibhodi le-hardware lisekela ukuxhumana kwangaphakathi, kodwa alikwazi ukuxhumana ne-inverter.Ukuhlola isampula ngu-8PIN, futhi iqoqo lokushisa linesokhethi ehlukile yomugqa.
Esinye sezici ezibalulekile zesistimu yethu yikhono lokushintsha inani lokusetha le-alamu kanye nemingcele yokuvikela ngokusebenzisa ikhompuyutha engusokhaya.Lokhu kuvumelana nezimo kuvumela abasebenzisi ukwenza ngendlela oyifisayo isistimu ngokwezidingo zabo ezithile, ukuqinisekisa ukuvikeleka okukhulu nokulawula ukusebenza kwebhethri.Ngokulungisa kalula i-alamu namapharamitha okuvikela, abasebenzisi bangamisa imingcele yokushaja futhi bakhiphe ama-currents, bagweme noma yiziphi izinkinga ezingaba khona noma umonakalo.
Ukuze unike amandla ukuqapha kwesikhathi sangempela kokushaja nokukhipha imisinga, isistimu yethu isebenzisa isivimbeli samanje sokutholwa esixhunywe kumjikelezo oyinhloko wephakethe lebhethri.Lesi sici siqoqa futhi siqaphe ukushaja nokukhipha imisinga, sinikeze ulwazi olunembile nolwakamuva.Ngokuqhubeka nokuqapha okwamanje, isistimu iyakwazi ukuthola noma yikuphi ukungahambi kahle noma ukuphambuka kumapharamitha asethiwe, ngaleyo ndlela inike amandla ama-alamu afika ngesikhathi kanye nokuvikela.
I-Cell Voltage Detection kanye Nohlelo Lwamanje Lokuqapha lwakhiwe ngokwethembeka kanye nokufaneleka komsebenzisi engqondweni.Ayiqinisekisi kuphela izilinganiso ezinembile nokulawula okuguquguqukayo, kodwa futhi kulula ukuyifaka futhi kulula ukuyisebenzisa.Isixhumi esibonakalayo esisebenziseka kalula sivumela ukuhlanganiswa okungenamthungo nezinhlobonhlobo zamaphakethe namasistimu ebhethri.
Sengiphetha, Ukutholwa Kwegesi Yamandla Kagesi kanye Nohlelo Lwamanje Lokuqapha lunikeza isixazululo esibanzi sokutholwa okunembile kwamandla kagesi kanye nokuqapha ngesikhathi sangempela ukushaja nokukhipha imisinga.Ngekhono lokushintsha i-alamu nemingcele yokuvikela, kanye nekhono lokuqoqa nokuqapha ama-currents ngesikhathi sangempela, isistimu yethu inikeza indlela ethembekile nephumelelayo yokuphathwa kwebhethri.Thuthukisa ukuqapha kwephakethe lakho lebhethri namuhla ngohlelo lwethu olusha noluthuthukisiwe.
(2) Umsebenzi wokuvikela isekethe emfushane:
Inomsebenzi wokuthola nokuvikela wesekethe emfishane yokuphumayo.
(3) Umthamo webhethri nenombolo yemijikelezo:
Ukubalwa kwesikhathi sangempela somthamo webhethri asele, ukufunda inani lokushaja namandla okuphuma ngesikhathi esisodwa, ukunemba kokulinganisa kwe-SOC okungcono kuno-±5%.Inani lokusetha lepharamitha yomthamo womjikelezo webhethri lingashintshwa ngekhompyutha ephezulu.
(4) Ukulingana kwamangqamuzana angawodwa ahlakaniphile:
Amaseli angalingani angalinganiswa ngesikhathi sokushajwa noma okubekwe eceleni, okungathuthukisa ngempumelelo isikhathi sesevisi nempilo yomjikelezo webhethri.I-voltage yokuvula elinganiselayo kanye nokucindezela kokuhluka okulinganiselwe kungasethwa yikhompyutha ephezulu.
(5) Ukushintsha inkinobho eyodwa:
Lapho i-BMS ihambisana, inkosi ingakwazi ukulawula ukuvalwa nokuqaliswa kwezigqila.Umsingathi kufanele ashayelwe ngemodi efanayo, futhi ikheli lokudayela lomsingathi alikwazi ukuvulwa nokuvalwa ngokhiye owodwa.(Ibhethri ligeleza kabusha kwelinye lapho lisebenza ngokufana, futhi alikwazi ukuvalwa ngokhiye owodwa).
(6) I-CAN, RM485, RS485 isixhumi esibonakalayo sokuxhumana:
I-CAN zokuxhumana ixhumana ngokuvumelana nephrothokholi ye-inverter ngayinye, futhi ingaxhunywa ku-inverter yokuxhumana.Ihambisana nemikhiqizo engaphezu kuka-40.
(7) Umsebenzi wokukhawulela wamanje wokushaja:
izindlela ezimbili zokukhawula zamanje ezisebenzayo kanye nomkhawulo wamanje we-passive, ungakhetha eyodwa ngokwezidingo zakho.
1. Umkhawulo wamanje osebenzayo: Uma i-BMS isesimweni sokushaja, i-BMS ihlale ivula ishubhu le-MOS lemojula yamanje yokukhawulela, futhi ibeka umkhawulo ekushajeni kube ngu-10A.
2. Umkhawulo wamanje ongenzi lutho: Esimeni sokushaja, uma amandla okushaja afinyelela inani le-alamu yokushaja okweqile, i-BMS izovula umsebenzi wokunciphisa wamanje ongu-10A, bese ihlola kabusha ukuthi ingabe ishaja yamanje iyafinyelela yini esimweni samanje somkhawulo ngemva kwemizuzu emi-5. yomkhawulo wamanje.(Vula inani lomkhawulo wamanje elingasethwa).
2.(1) Ukutholwa komthamo weseli nebhethri:
Ukunemba kokutholwa kwe-voltage yeseli ngu-±10mV ku-0-45°C, kanye no-±30mV ku--20-70°C ngokushajwa kwebhethri nokutholwa kwamanje kokukhipha.Inani lokusetha le-alamu nemingcele yokuvikela lingashintshwa ngekhompyutha yokusingatha, futhi isivimbeli samanje sokutholwa esixhunywe kumjikelezo oyinhloko wokushaja nokukhipha singasetshenziswa ukuqoqa nokuqapha ukushajwa nokukhipha amandla ephaketheni lebhethri ngesikhathi sangempela, ukuze ubone i-alamu kanye nokuvikelwa kokushaja kwamanje kanye nokukhishwa kwamandla, ngokunemba okuhle kakhulu kwamanje kokuthi ±1.
(2) Umsebenzi wokuvikela isekethe emfushane:
Inomsebenzi wokuthola nokuvikela wesekethe emfishane yokuphumayo.
(3) Umthamo webhethri nenombolo yemijikelezo:
Ukubalwa kwesikhathi sangempela somthamo webhethri asele, ukufunda inani lokushaja namandla okuphuma ngesikhathi esisodwa, ukunemba kokulinganisa kwe-SOC okungcono kuno-±5%.Inani lokusetha lepharamitha yomthamo womjikelezo webhethri lingashintshwa ngekhompyutha ephezulu.
(4) Ukulingana kwamangqamuzana angawodwa ahlakaniphile:
Amaseli angalingani angalinganiswa ngesikhathi sokushajwa noma okubekwe eceleni, okungathuthukisa ngempumelelo isikhathi sesevisi nempilo yomjikelezo webhethri.I-voltage yokuvula elinganiselayo kanye nokucindezela kokuhluka okulinganiselwe kungasethwa yikhompyutha ephezulu.
(5) Ukushintsha inkinobho eyodwa:
Lapho i-BMS ihambisana, inkosi ingakwazi ukulawula ukuvalwa nokuqaliswa kwezigqila.Umsingathi kufanele ashayelwe ngemodi efanayo, futhi ikheli lokudayela lomsingathi alikwazi ukuvulwa nokuvalwa ngokhiye owodwa.(Ibhethri ligeleza kabusha kwelinye lapho lisebenza ngokufana, futhi alikwazi ukuvalwa ngokhiye owodwa).
(6) I-CAN, RM485, RS485 isixhumi esibonakalayo sokuxhumana:
I-CAN zokuxhumana ixhumana ngokuvumelana nephrothokholi ye-inverter ngayinye, futhi ingaxhunywa ku-inverter yokuxhumana.Ihambisana nemikhiqizo engaphezu kuka-40.
(7) Umsebenzi wokukhawulela wamanje wokushaja:
Izindlela ezimbili zokukhawula zamanje ezisebenzayo kanye nokukhawulela yamanje, ungakhetha eyodwa ngokuya ngezidingo zakho.
1. Umkhawulo wamanje osebenzayo:Lapho i-BMS isesimweni sokushaja, i-BMS ihlale ivula ishubhu le-MOS lemojula yamanje yokukhawulela, futhi ibeka umkhawulo ekushajini kokuthi kube ngu-10A.
2. Umkhawulo wamanje ongenzi lutho: Esimeni sokushaja, uma amandla okushaja afinyelela inani le-alamu yokushaja okweqile, i-BMS izovula umsebenzi wokunciphisa wamanje ongu-10A, bese ihlola kabusha ukuthi ingabe ishaja yamanje iyafinyelela yini esimweni samanje somkhawulo ngemva kwemizuzu emi-5. yomkhawulo wamanje.(Vula inani lomkhawulo wamanje elingasethwa).
Kuyini Ukusetshenziswa?
Inemisebenzi yokuvikela nokuthola kabusha efana ne-overvoltage eyodwa/undervoltage, isamba se-voltage undervoltage/overvoltage, ukushaja/ukukhulula i-overcurrent, izinga lokushisa eliphezulu, izinga lokushisa eliphansi kanye nesifunda esifushane.Thola ukulinganiswa okunembile kwe-SOC ngesikhathi sokushaja nokukhipha, kanye nezibalo zesimo sezempilo se-SOH.Thola ibhalansi kagesi ngesikhathi sokushaja.Ukuxhumana kwedatha nomsingathi ngokuxhumana kwe-RS485, ukumiswa kwepharamitha nokuqapha idatha ngokusebenzisana kwekhompyutha ephezulu yesofthiwe yekhompyutha ephezulu.
Izinzuzo
1. Ngezinhlobonhlobo zezesekeli zokunweba zangaphandle: I-Bluetooth, isibonisi, ukufudumeza, ukupholisa umoya.
2. Indlela yokubala ye-SOC eyingqayizivele: indlela ehlanganisiwe yehora le-ampere + i-algorithm yangaphakathi yangaphakathi.
3. Umsebenzi wokudayela okuzenzakalelayo: umshini ofanayo unikeza ngokuzenzakalelayo ikheli lenhlanganisela yephakethe ngalinye lebhethri, elilungele abasebenzisi ukwenza ngokwezifiso inhlanganisela.
