TL;DR – Leswi U Nga Ta Swi Dyondza hi Tisekoni ta 30:
• Ndlela ya ntolovelo ya ku hakela lithium-ion i CC-CV (Constant Current-Constant Voltage).
• Xiphemu xa CC xi nyika ku chaja hi ku hatlisa (ku fika eka 60-80% wa vuswikoti), xiyenge xa CV xi tiyisisa ku topping-off loku hlayisekeke na ku sirhelela vutomi bya betri.
• Ku hisa lokukulu (ehansi ka 0°C kumbe ehenhla ka 45°C) swi onha eka ku chaja.
• A munhu la tinyiketeleke Sisiteme ya Vulawuri bya Betiri (BMS) i ya nkoka eka vulawuri lebyi kongomeke bya voltage na current.
Ndlela leyi u chajaka betri ya lithium-ion ha yona i xin’wana xa swilo swa nkoka swinene leswi lawulaka vutomi bya yona, ndlela leyi yi tirhaka ha yona ni vuhlayiseki bya yona. Hambi leswi swinga vonakaka tani hi ntirho wa ntolovelo, endlelo ro chaja lithium-ion ri yime etlhelo ka thekinoloji ya khale ya betri yofana na lead-acid kumbe NiMH. Ku landzelela maendlelo lamanene i xilotlelo xo sivela ku nga tirhi kahle na ku kurisa ROI.
Ha yini Endlelo ra Lithium-Ion Charge ri Hlawuleka
Ku hambana ni tibetiri ta lead-acid, tisele ta lithium-ion a ti swi koti ku tiyisela ku chaja ku tlula mpimo. Ti lava current yo chaja leyi lawuriwaka kahle na voltage kutiyisisa leswaku ti lithium ions ti nghena hiku hlayiseka eka ti layers ta graphite ta anode. Ndlela ya ntolovelo, leyi amukeriwaka hi indasitiri ya xibalo xa lithium-ion lexi heleleke no hlayiseka i algorithm ya CC-CV (Constant Current-Constant Voltage). A xi tiyile Sisiteme ya Vulawuri bya Betiri (BMS) i ya nkoka swinene ku tirhisa algorithm leyi hi ndlela leyinene.
Xiyenge xa 1: Current ya Nkarhi hinkwawo (CC) – Xiphemu xa ku Chaja hi ku Hatlisa
Hi nkarhi wa xiyenge xa current leyi nga cinciki, chajara yi phakela current leyi tiyeke, leyi vekiweke ka ha ri emahlweni.
• Swihlawulekisi : Voltage yi tlakuka hi ku nonoka kasi current yi tshama yi nga cinci.
• Vuswikoti lebyi kumiweke : Betiri ya Li-ion yi nga fikelela 60% ku ya eka 80% wa vuswikoti bya yona hinkwabyo hi nkarhi wa xiteji lexi.
• C-Rate : Current ya kahle yo chaja hi ntolovelo yiva exikarhi ka 0.2C na 1.0C. Eka sele ya 2000mAh, mpimo wa 0.5C wutava 1000mA.
• Transition Point : Xiphemu xa CC xi ya emahlweni ku kondza voltage ya sele yi fika eka mpimo wa yona wa le henhla, hi ntolovelo kwalomu ka 4.2V hi sele.
Xiyenge xa 2: Voltage ya Nkarhi hinkwawo (CV) – Topping-Off yo Sirhelela
Loko ku fikeleriwile 4.2V threshold, chajara yi cincela hi ndlela yo pfumala swiphiqo eka constant voltage mode.
• Swihlawulekisi : Chajara yi khoma voltage yi nga cinci loko current yi ri karhi yi hunguteka hi ku nonoka.
• Ha Yini Swi Laveka : Handle ka xiteji lexi xa CV, current a yi ta ya emahlweni yi susumeta ti ions endzeni, leswi endlaka leswaku lithium ya nsimbi yi plate eka anode, xivangelo lexikulu xa ku baleka hi ku hisa.
• Ku herisiwa : Xirhendzevutani xa ku chaja ka lithium-ion xi hela, kumbe ku hela, loko current yo chaja yi ya ehansi eka xiyimo xa le hansi xa 'end-of-charge', hi ntolovelo exikarhi ka 0.02C na 0.07C.
Maendlelo lamanene na ku Langutisisa ka BMS
Vulawuri bya ku hakela a byi humeleli eka ndhawu leyi nga riki na nchumu. Eka switirhisiwa swa xiviri swo fana na tisenthara ta data kumbe switichi swa le hansi swa thelekhomu, a robust
Sisiteme ya Vulawuri bya Betiri (BMS) i ya nkoka.
✅
Ku Langutisisa Mahiselo : Ku chaja swifanele ku humelela kahle exikarhi ka 0°C na 45°C.
✅
Ku Hlawula Chajara : Minkarhi hinkwayo tirhisa chajara leyi endleriweke tikhemikhali ta Li-ion leyi landzelaka xivumbeko lexinene xa CC-CV.
✅
Voltage Precision : BMS ya khwalithi yi tiyisisa leswaku sele yin’wana na yin’wana yi fikelela voltage leyinene, ku kurisa vuswikoti eka xirhendzevutani xin’wana na xin’wana xa ku chaja.
Matirhiselo ya Misava ya Xiviri eka Matimba ya Nkoka
Misinya ya milawu ya ku chaja lithium-ion loku hlayisekeke ni loku tirhaka kahle a hi ya dyondzo ntsena; i masungulo eka tisisiteme ta manguva lawa ta vuhlayiselo bya gezi. Endzeni ka UPS, tibetiri ta lithium tinyika nhlayo yale henhla ya eneji eka matimba ya backup yo koma swinene. Ku kongoma ka ndlela ya CC-CV i swa nkoka swinene eka ku tshembheka. Ku engetela kwalaho, ku tirhisiwa loku kulaka ka matimba ya dyambu na Tisisiteme ta Vuhlayiselo bya Eneji ya Betiri (BESS) swi titshege hi tialgorithm to chaja leti rharhanganeke ku kurisa vutomi bya ku hlanganisa eneji leyi pfuxetiwaka na vuhlayiselo bya betri.
Eka switirhisiwa swa nkoka wa vurhumiwa, DFUN yi nyika swa xiyimo xa le henhla swintshuxo swa betri ya lithium-ion leswi endleriweke ku tirha hi ndlela yo pfumala swiphiqo na pulatifomo ya hina ya BMS, ku tiyisisa matirhelo lamanene ya ku chaja, vutomi bya xirhendzevutani lebyi engetelekeke, na vuhlayiseki lebyi antswisiweke.
