Ukutshaja iibhetri zeLiFePO4 ngeSolar

Kuyenzeka ukutshaja iibhetri zeLithium Iron Phosphate ngephaneli yelanga. Ungasebenzisa nasiphi na isixhobo ukuhlawulisa i-12V LiFePO4 ukuba nje isixhobo sokutshaja sinombane osuka kwi-14V ukuya kwi-14.6V. Ukuze yonke into isebenze kakuhle ngelixa utshaja iibhetri zeLiFePO4 ngeSolar panel, udinga umlawuli wentlawulo.

Ngokucacileyo, xa utshaja iibhetri zeLiFePO4, akufuneki usebenzise iitshaja ezenzelwe ezinye iibhetri ze-lithium-ion. Iitshaja ezinombane ophezulu kakhulu kunento ekuthethwa ngayo kwiibhetri zeLiFePO4 zinokunciphisa amandla kunye nokusebenza kwazo. Unokusebenzisa itshaja yebhetri ye-lead-asidi kwiibhetri zeLithium iron phosphate ukuba iisetingi zamandla ombane ziphakathi kwemida eyamkelekileyo yeebhetri zeLiFePO4.

Ukuhlolwa kweetshaja zeLiFePO4

Njengoko ulungiselela ukutshaja ibhetri ye-LiFePO4 ngelanga, kuyacetyiswa ukuba uhlole iintambo zokutshaja kwaye uqinisekise ukuba zinobushushu obufanelekileyo, azinacingo eziqhekezayo kunye nokwaphuka. Iitheminali zetshaja kufuneka zicoceke kwaye zifaneleke ukwenza uqhagamshelwano oluluqilima neetheminali zebhetri. Uqhagamshelo olululo lubalulekile ukuze kuqinisekiswe ukusebenza kakuhle.

IziKhokelo zokuTshaja iibhetri zeLiFePO4

Ukuba ibhetri yakho yeLiFePO4 ayinakuphuma ngokupheleleyo, akunyanzelekanga ukuba uyibize emva kokusetyenziswa kwayo yonke into. Iibhetri ze-LiFePO4 zomelele ngokwaneleyo ukuba zingamelana nomonakalo onxulunyaniswa nexesha nokuba uzishiya zikwimo yentlawulo kangangeenyanga.

Kuvumelekile ukuba ubize ibhetri ye-LiFePO4 emva kokusetyenziswa ngakunye okanye ngokukhethwayo xa ikhutshwe ukuya kuthi ga kwi-20% ye-SOC. Xa iisistim zoLawulo lweBhetri ziqhawula ibhetri emva kokuba ibhetri yehla kakhulu amandla ombane angaphantsi kwe-10V, kufuneka uwususe umthwalo kwaye uwutshaje ngokukhawuleza usebenzisa itshaja yebhetri yeLiFePO4.

Ubushushu bokuTshaja beebhetri zeLiFePO4

Ngokuqhelekileyo, iibhetri zeLiFePO4 zitshaja ngokukhuselekileyo kumaqondo obushushu aphakathi kwe-0°C ukuya kuma-45°C. Aziyifuni imbuyekezo yombane kunye nobushushu nokubanda kwamaqondo obushushu okanye abandayo.

Zonke iibhetri ze-LiFePO4 ziza kunye ne-BMS (iNkqubo yoLawulo lweBattery) ekhusela kwimiphumo eyingozi yokushisa kweqondo lokushisa. Ukuba amaqondo okushisa aphantsi kakhulu, i-BMS ivuselela ukuchithwa kwebhetri, kwaye iibhetri ze-LiFePO4 zinyanzeliswa ukuba zifudumale ukuze i-BMS iphinde idibanise kwakhona kwaye ivumele ukutshaja kwangoku ukuba kuhambe. I-BMS iza kuqhawuka kwakhona kowona bushushu bushushu ukuvumela indlela yokupholisa ithobe amaqondo obushushu ebhetri ukuze inkqubo yokutshaja iqhubeke.

Ukwazi iiparamitha ze-BMS ezithile zebhetri yakho, kufuneka ubhekiselele kugcino-lwazi olubonisa amaqondo obushushu aphezulu naphantsi apho i-BMS iya kuwacima. Amaxabiso oqhakamshelwano kwakhona abonakaliswe kwincwadana efanayo.

Ukutshaja kunye nokukhupha amaqondo okushisa kwiibhetri ze-lithium kwi-series ye-LT zirekhodwa kwi -20 ° C ukuya kwi-60 °. Sukuba nexhala xa uhlala kwindawo ezinobushushu obuphantsi kakhulu, ngakumbi ebusika. Kukho iibhetri zeLithium ezinobushushu obuphantsi ezenzelwe ngokukodwa ukusebenzela abantu abakwiindawo ezibandayo. Iibhetri zeLithium ezinobushushu obuphantsi zinenkqubo yokufudumeza eyakhelwe ngaphakathi, kunye neteknoloji ephucukileyo ekhupha amandla okufudumeza kwiitshaja hayi ibhetri.

Xa uthenga iibhetri zeLithium ezinobushushu obuphantsi, ziya kusebenza ngaphandle kwezinto ezongezelelweyo. Yonke inkqubo yokufudumeza kunye nokupholisa ayisayi kuchaphazela indawo yolawulo lwelanga kunye nezinye iziqhoboshi. Ayinamthungo ngokupheleleyo kwaye isebenze ngokuzenzekelayo xa ubushushu bubetha ngaphantsi kwe-0°C. Iyacinywa kwakhona xa ingasasetyenziswa; kulapho ubushushu bokutshaja buzinzile.

Indlela yokufudumeza kunye neyokupholisa yeebhetri zeLiFePO4 ayiwakhuphi amandla kwibhetri ngokwayo. Endaweni yoko isebenzisa into efumanekayo kwiitshaja. Ubumbeko luqinisekisa ukuba ibhetri ayiphumi. Ukufudumeza kwangaphakathi kunye nokujongwa kobushushu bebhetri yakho yeLiFePO4 qalisa ngoko nangoko emva kokudibanisa itshaja yeLiFePO4 kwilanga.

isiphelo

Iibhetri ze-LiFePO4 zinekhemistri ekhuselekileyo. Zikwakhona iibhetri ze-lithium-ion ezihlala ixesha elide ezinokuhlawuliswa ngepaneli yelanga ngokuqhubekayo ngaphandle kweengxaki. Kufuneka wenze kuphela uhlolo lwetshaja olululo. Nokuba kuyabanda, iibhetri zeLiFePO4 aziyi kuphuma. Ngokubanzi, udinga kuphela iitshaja ezihambelanayo kunye nabalawuli ukutshaja ibhetri yakho yeLiFePO4 ngephaneli yelanga ngokukhuselekileyo.
