Iibhetri zentsimbi yeLithium, ezaziwa ngokuphakama kwazo ukuxinana kwamandla kwaye ubude Ubomi bomjikelo, ziya zithandwa kakhulu kwizicelo ezifana neenqwelo zombane kunye nokugcinwa kwamandla avuselelekayo. Ukhathalelo olufanelekileyo lubalulekile ekusebenzeni ngokugqibeleleyo, ubomi obude, kunye nokhuseleko. Esi sikhokelo siphonononga ezona ndlela zilungileyo zokugcina ezi bhetri, kubandakanywa iiprothokholi zokutshaja kunye neendlela zokugcina.
Yintoni ibhetri yentsimbi yeLithium?
I-lithium iron phosphate (LiFePO4 okanye i-LFP) ibhetri luhlobo lwebhetri ye-lithium-ion eyaziwayo ngesakhiwo sayo esilula kunye nobuninzi bamandla.
Uninzi lweebhetri ze-lithium zensimbi ziqulethe iiseli ezininzi ze-LiFePO4 kunye ne-a BMS. Iseli nganye ibandakanya i-cathode, i-anode, i-separator, i-electrolyte, kunye nabaqokeleli ababini bangoku. I i-anode kunye ne-cathode gcina i-lithium, ngelixa i-electrolyte idlulisela ngokufanelekileyo i-lithium nge-separator. Le ntshukumo yentlawulo iyavelisa I-Voltage, eyenza umsinga wombane uqukuqele ukusuka kwitheminali evumayo ukuya kwisicelo sakho kwaye ubuyele kwitheminali ekhabayo.
Uyigcina njani ibhetri yentsimbi yeLithium?
Iibhetri ze-lithium zentsimbi ezinokutshajwa kwakhona zinomda umsebenzi wobomi kwaye ekugqibeleni baya kuphulukana namandla abo okubamba intlawulo ngokusisigxina. Ke, ukhathalelo olufanelekileyo kunye nokugcinwa kubalulekile ukuze ubomi obude.
Ubomi obuqikelelwayo bebhetri yentsimbi ye-lithium yiminyaka emi-5-15, kuxhomekeke ekusebenziseni. Ibhetri ye-LiFePO4 inokunikezela ukuya kuthi ga kwimijikelo yokutshaja eyi-2000 okanye imijikelo engama-6000. Umjikelo ogcweleyo uyashukuma ukusuka ekutshajisweni ukuya ekukhutshweni ngokupheleleyo, emva koko ubuyele ekutshajisweni ngokupheleleyo. Ukushiya iibhetri zingasetyenziswanga ixesha elongeziweyo kunokubenza bufutshane ubomi babo kwaye kukhokhelele ekusileleni.
Sincoma ukuqhuba ubuncinane umjikelezo wokugcinwa okupheleleyo (ukuhlawula kwi-100% ye-SoC, ukukhutshwa kwi-100% ye-DoD, emva koko uhlawule kwi-50% ye-SoC) zonke iinyanga ze-6-12 kuzo zonke iibhetri ze-lithium ezingasetyenziswanga kunye neeseli. Qwalasela iibhetri ezigciniweyo ze-OCV eyaneleyo (ivolthi yesekethe evulekileyo) usebenzisa le theyibhile ingezantsi malunga nomthamo wombane ocetyiswayo wokugcina. Ukuba i-voltage iphantsi ngexesha lokuhlolwa kolungiso, i-Holo Battery incoma ukutshaja kwakhona ibhetri yakho njengoko kufuneka.

Ukufumana ugcino olungcono lweeseli okanye iibhetri, zihlole rhoqo emva kweenyanga ezintandathu ukubona iimpawu zomhlwa kunye nemiba yemfezeko yetyala. Kuphephe ukusebenzisa iibhetri ezonakalisiweyo ukuthintela iingozi zokhuseleko.
Iibhetri zeLiFePO4 zinezinga elicothayo lokuzikhupha ngexesha lokugcinwa. Nangona kunjalo, ukuba baneBluetooth okanye ukusebenza kweWiFi, isantya sokukhupha sinokunyuka ngenxa yokutsala amandla emodyuli. Ukubeka iliso rhoqo kwinqanaba lentlawulo yebhetri yakho kubalulekile ukugcina impilo yayo kunye nokugcina ukuphuma kwamandla.
Ukuvavanya impilo yebhetri yakho, jonga ixesha lokusetyenziswa kwesicelo sakho njengemetric elula. Seka isiseko ngokurekhoda ixesha lokuqala lokuqhutywa kwebhetri yakho entsha ye-lithium ukuze uthelekise njengoko iminyaka ihamba. Olu phawu lunokwahluka ngokuxhomekeke kusetyenziso nakumo lwebhetri.
NdiyiTshaja Njani Ibhetri yentsimbi yeLithium?
Itshaja yebhetri ye-lithium iqinisekisa umjikelo opheleleyo wokutshaja. Iitshaja zethu zeLiFePO4 zisebenzisa ubukrelekrele bokutshaja okunamanyathelo ama-3 ukuvuselela iibhetri ezikhutshwe nzulu.
Ukongeza, itekhnoloji yokutshaja ephuculweyo yonyusa ukusebenza kunye nobomi ngokusebenzisa ngokufanelekileyo amandla ebhetri.
Funda ngakumbi kwinqaku elithi “Iibhetri zeLithium lron Phosphate (LiFePO4).”.
Leliphi inqanaba lokuTshaja eliya kwandisa uBomi bebhetri yentsimbi yeLithium?
Iitshaja zikhethwa ngokusekelwe kumthamo webhetri. Iibhetri ze-lithium zinokuhlawulisa kwiirhafu ukuya kwi-1C (umthamo wazo opheleleyo), ngelixa iibhetri ze-lead-acid kufuneka zihlawulwe ngaphantsi kwe-C / 3. Ngokomzekelo, ibhetri ye-lithium ye-9Ah ihlawulisa kwi-9 amps, ngelixa i-9Ah ibhetri ye-lead-acid kufuneka ihlawule malunga ne-3 amps.
Ukwandisa ixesha lokuphila kwebhetri yakho ye-LiFePO4 kunye nokunciphisa ixesha lokuphumla, kuyacetyiswa ukuba uyihlawule ngaphakathi koluhlu lwe-C / 4 ukuya kwi-C / 2. Kwibhetri ye-10Ah, oku kuthetha ukutshaja kwi-2.5A ukuya kwi-5A, kunye ne-2.5A efanelekileyo. Ukuba kufuneka ukhethe phakathi kwe-2A kunye ne-5A tshaja, khetha itshaja ye-2A yokwandisa ubomi bebhetri, nangona ixesha lokutshaja ixesha elide malunga neeyure ezi-5.
Intlawulo ye-cutoff yangoku ibekwe ngokuqhelekileyo phakathi kwe-2.5-5% yomthamo webhetri, okubangela ukuba uluhlu lwangoku lwe-cutoff lujikeleze i-0.25-0.50A kwimizekelo ye-10Ah. Uninzi lweetshaja ziziphatha ngokuzenzekelayo oku kusikeka ngaphandle kohlengahlengiso lwezandla.
Iitshaja zendalo yonke zibonelela ngokulula ekukhetheni iindidi zeekhemikhali ezahlukeneyo, ziqinisekisa awona manqanaba ombane agqwesileyo kunye neendlela ezifanelekileyo zokuvala xa zifikelela kwintlawulo epheleleyo. Umzekelo, ezi tshaja zinokuzivalela ngokuzenzekelayo iibhetri ze-lithium okanye zitshintshele kwimowudi yentlawulo edadayo kwiibhetri ezitywiniweyo ze-lead-acid (SLA), ziphucula ukhuseleko kunye nokusebenza kakuhle kwenkqubo yokutshaja.
Ukugcinwa kwexesha elide
Xa ugcina iibhetri ixesha elide, qwalasela iimfuno ezahlukeneyo ze-SLA kunye neebhetri ze-lithium.
Gcina iibhetri ze-SLA kufuphi ne-100% ye-state of charge (SoC) ukukhusela i-sulfating, okunciphisa umthamo ngenxa ye-sulfate crystal buildup. Iibhetri zeLithium kufuneka zigcinwe malunga ne-50% ye-SoC ukugcina uzinzo kwi-terminal efanelekileyo kwaye ugweme ukulahlekelwa kwamandla okusisigxina. Ngezikhokelo ezithile malunga nokugcinwa kwebhetri ye-lithium, bhekisa kuthi isikhokelo esizinikeleyo.
Amazinga okuzikhupha ngokwawo nawo achaphazela ukugcinwa: Iibhetri ze-SLA zinezinga eliphezulu lokuzikhupha kwaye kufuneka zigcinwe kwi-float okanye i-trickle charge kufuphi ne-100% ye-SoC. Ngokwahlukileyo, iibhetri ze-lithium zinezinga eliphantsi lokukhupha kwaye zinokufuna ukutshaja okuncinci kokulondolozwa ukuba akukho parasitic imizobo efana neemodyuli zeBluetooth.
Uyigcina Njani ibhetri yeLithium-ion ekuMboleni?
Ibhetri yeHolo ineempawu ezidityanisiweyo kwizinto zethu iitheminali zebhetri ukulwa umhlwa. Nangona kunjalo, iibhetri zisenokonakala ngokuhamba kwexesha ngaphandle kokhathalelo.
Ungawunciphisa umhlwa ngokulandela la manyathelo:
- Gcina ibhetri yakho kwindawo epholileyo, eyomileyo ukunciphisa umhlwa kunye nokwandisa ubomi bayo beshelufu.
- Vala iitheminali ngesitshizi esisikhuselayo kwiivenkile zezixhobo zemoto ukwenzela uthintelo olululo.
- Hlala uhlola kwaye ucoce iitheminali zakho zebhetri ye-lithium ngelaphu elomileyo elithambileyo ukuba zibonakala zimdaka ukunqanda ukwakheka okunzima kamva.
