Ibhethri le-LiFePO4: ukuvimbela ukusha kwe-voltage yeseli, i-over-voltage, kanye nezinga lokushisa elingaphezulu Umugqa wokuqala wokuvikela ukulinganisa kwamaseli. Wonke amabhethri e-Victron LiFePO4 ahlanganisa ukulinganisa kwamaseli.
Umugqa wesibili wokuvikela uqukethe:
- ukuvala umthwalo uma kwenzeka iseli eliseduze ngaphansi kwe-voltage, futhi
- ukuvala noma ukunciphisa amandla okushaja uma kwenzeka iseli lisondele kakhulu ku-voltage, izinga lokushisa eliphezulu
(>50°C) noma izinga lokushisa eliphansi (<0°C).
I-VE.Bus BMS iwumgogodla wolayini wokuvikela wesibili.
Nokho, akuzona zonke izinto ezilayishiwe noma amashaja angalawulwa ngokuqondile yi-VE.Bus BMS.
Ukuze uvale imithwalo enjalo noma amashaja amaswishi ambalwa e-VE.Bus BMS alawulekayo e-Cyrix ayatholakala.
I-Cyrix-Li-load I-Cyrix-Li-load izonqamuka lapho okokufaka kokulawula kwayo kuba kuntanta mahhala.
Uma i-voltage yebhethri ilulama ngemuva kokunqamuka (okuzokwenzeka lapho kungekho eminye imithwalo exhunywe ku-
ibhethri), ukuphuma kwe-BMS kuzoba phezulu futhi i-Cyrix izosebenza kabusha ngemva kwemizuzwana engu-30. Ngemva kwemizamo emi-3
ukuze izibandakanye kabusha, i-Cyrix izohlala ingasebenzisi kuze kube yilapho amandla omthamo webhethri akhuphuka abe ngaphezu kuka-13V (resp. 26V noma
52V) phakathi namasekhondi okungenani angu-30 (okuwuphawu lokuthi ibhethri liyashajwa).
I-Cyrix-Li-Charge I-Cyrix-Li-Charge izoxhuma ishaja yebhethri ngokulibaziseka kwamasekhondi angu-3:
- uma Ukushaja Nqamula okukhiphayo kwe-VE.Bus BMS kuphezulu, futhi
- uma izwa i-13,7V (resp. 27,4V noma 54,8V) noma ngaphezulu kutheminali yayo yokuxhuma ishaja yebhethri, futhi
- uma izwa i-2V noma ngaphezulu kutheminali yayo yebhethri (i-Cyrix izohlala ivulekile, uma ingaxhumekile ebhethrini).
I-Cyrix-Li-Charge izonqamuka ngokushesha noma nini lapho okukhiphayo kokulawula kubandanda ngokukhululekile, iseli elisayinayo.
overvoltage noma iseli phezu kwezinga lokushisa.
Ngokuvamile, i-alamu yeseli phezu kwe-voltage izosethwa kabusha maduze nje ngemva kokumiswa kokushaja. UCyrix uzokwenza kanjalo
xhuma kabusha ishaja. Ngemuva kwemizamo emi-2 yokuzibandakanya kabusha nokulibaziseka kwamasekhondi angu-3, ukubambezeleka kukhuphuka kube yimizuzu eyi-10.
Noma kunini lapho i-voltage yebhethri ingaphansi kuka-13,5V (resp. 27V noma 54V), i-Cyrix izokhipha ukubambezeleka kwehora elingu-1.
Qaphela 1 : Endabeni yokukhipha i-zero yamanje, noma ukukhishwa okuncane kwamanje, i-Cyrix ngeke inqamule ngemva nje kwalokho.
ishaja icishiwe futhi/noma inqanyuliwe ngenxa yokuthi amandla omthamo webhethri azohlala ephakeme kuno-13,5V.
Qaphela 2 : Uma, ngemva kokuthi i-Cyrix isinqamukile, ukuphuma kweshaja yebhethri kukhuphuka ngokushesha kube ngu-13,7V noma
ngaphezulu, i-Cyrix izophinde ihlanganyele, ngokulibaziseka kwamasekhondi angu-3.
I-Cyrix-Li-ct Ukusebenza kwe-Cyrix-Li-ct kufana ne-Cyrix-ct.
I-Cyrix-Li-ct izohambisana ngokuhambisana nokuxhuma ibhethri eliqalisa i-lead-acid kanye nebhethri ye-LiFePO4:
- Uma Ukushaja Nqamula okukhiphayo kwe-VE.Bus BMS kuphezulu, futhi
- Uma izwa 13,4V (resp. 26,8V) noma ngaphezulu kwenye yamatheminali ayo amandla.
I-Cyrix izokhipha ngokushesha:
- Lapho okukhiphayo kokulawula kuba ukuntanta mahhala, kubonisa iseli phezu kwe-voltage noma iseli phezu kwezinga lokushisa,
kanye/noma
- Lapho i-voltage yebhethri yehla ngaphansi kuka-13,2V.
Qala umsebenzi wokusiza: ukushaya kwenhliziyo okufushane kuzovala imizuzwana engama-30 (bheka umfanekiso ekhasini 2).
I-voltage suppressor eyakhelwe ngaphakathi izokhawulela i-voltage spike engenzeka lapho i-Cyrix kungazelelwe
iyanqamula ngenxa yokugcwala kweseli noma izinga lokushisa elingaphezulu.
