Kodwa nanku umbuzo ekufuneka ucamngce ngawo: Ukufundwa kwamandla ombane kunokutshintsha njani phantsi komthwalo xa kuthelekiswa nokuphumla? Kwaye ungayiphendula njani le nto kwisicwangciso sakho solawulo lwebhetri?
Ngokusebenzisa iitshathi zombane zeLiFePO4, awufundi nje amanani-uvula ulwimi oluyimfihlo lweebhetri zakho. Olu lwazi lukunika amandla okwandisa ukusebenza, ukwandisa ubomi, kwaye ufumane okuninzi kwinkqubo yakho yokugcina amandla.
Ingaba iVoltage iyichaphazela njani iLiFePO4 yokuSebenza kwebhetri?
I-Voltage idlala indima ebalulekileyo ekumiseleni iimpawu zokusebenza kweebhetri ze-LiFePO4, ezichaphazela amandla abo, ubuninzi bamandla, ukuphuma kwamandla, iimpawu zokutshaja kunye nokhuseleko.
Ukulinganisa iVoltage yeBattery
Ukulinganisa amandla ebhetri ngokuqhelekileyo kubandakanya ukusebenzisa i-voltmeter. Nasi isikhokelo ngokubanzi malunga nendlela yokulinganisa amandla ombane ebhetri:
1. Khetha iVoltmeter efanelekileyo: Qinisekisa ukuba i-voltmeter inokulinganisa umbane olindelekileyo webhetri.
2. Cima iSekethe: Ukuba ibhetri iyinxalenye yesekethe enkulu, yicime isekethi phambi kokuba wenze imilinganiselo.
3. Qhagamshela iVoltmeter: Qhoboshela iVoltmeter kwiitheminali zebhetri. Intambo ebomvu idibanisa kwi-terminal evumayo, kwaye i-black lead idibanisa kwi-terminal engafanelekanga.
4. Funda i-Voltage: Emva kokuba ixhunyiwe, i-voltmeter iya kubonisa amandla ombane webhetri.
5. Tolika ukuFunda: Qaphela ufundo olubonisiweyo ukumisela amandla ombane ebhetri.

Ngokubhekiselele kwitshathi yombane ye-LiFePO4, unokwenza izigqibo ezinolwazi malunga nokutshaja, ukukhupha, kunye nolawulo lwebhetri iyonke, ekugqibeleni wandise ukusebenza kunye nobomi bezi zisombululo zokugcina amandla aphezulu.
Ukuqukumbela, itshathi yombane isebenza njengesixhobo esibalulekileyo kwiinjineli, abahlanganisi benkqubo, kunye nabasebenzisi bokuphela, ukubonelela ngemibono ebalulekileyo ekuziphatheni kweebhetri ze-LiFePO4 kunye nokwenza ukulungelelaniswa kweenkqubo zokugcina amandla kwizicelo ezahlukeneyo. Ngokuthobela amanqanaba ombane acetyiswayo kunye neendlela ezifanelekileyo zokutshaja, unokuqinisekisa ixesha elide kunye nokusebenza kakuhle kweebhetri zakho zeLiFePO4.
FAQ Malunga neLiFePO4 Itshati yeBattery Voltage
Umbuzo: Ndiyifunda njani itshathi yombane webhetri yeLiFePO4?
A: Ukufunda itshathi yombane webhetri ye-LiFePO4, qala ngokuchonga i-X kunye ne-Y axes. I-X-axis idla ngokumela imeko yebhetri yentlawulo (SoC) njengepesenti, ngelixa i-Y-axis ibonisa umbane. Jonga igophe elimele ukukhutshwa kwebhetri okanye umjikelo wentlawulo. Itshathi iya kubonisa indlela amandla ombane atshintsha ngayo njengoko ibhetri iphuma okanye itshajiswa. Nika ingqalelo kumanqaku aphambili afana nombane oqhelekileyo (ngokuqhelekileyo ujikeleze i-3.2V ngeseli) kunye nombane kumanqanaba ahlukeneyo e-SoC. Khumbula ukuba iibhetri zeLiFePO4 zinejiko lamandla ombane athambileyo xa kuthelekiswa nezinye iikhemistri, okuthetha ukuba umbane uhlala uzinzile kuluhlu olubanzi lweSOC.
Q: Loluphi uluhlu lwamandla ombane olufanelekileyo kwibhetri yeLiFePO4?
A: Uluhlu olufanelekileyo lwe-voltage yebhetri ye-LiFePO4 ixhomekeke kwinani leeseli kuthotho. Kwiseli enye, uluhlu olusebenzayo olukhuselekileyo luhlala luphakathi kwe-2.5V (ikhutshwe ngokupheleleyo) kunye ne-3.65V (ihlawulwe ngokupheleleyo). Kwipakethi yebhetri ye-4 (12V nominal), uluhlu luya kuba yi-10V ukuya kwi-14.6V. Kubalulekile ukuqaphela ukuba iibhetri ze-LiFePO4 zinejika lamandla ombane esicaba, okuthetha ukuba zigcina amandla ombane angaguqukiyo (malunga ne-3.2V ngeseli nganye) kuninzi lomjikelo wazo wokukhupha. Ukwandisa ubomi bebhetri, kuyacetyiswa ukuba ugcine imeko yentlawulo phakathi kwe-20% kunye ne-80%, ehambelana noluhlu lwamandla ombane oluncinci.
Q: Ubushushu buchaphazela njani i-voltage yebhetri ye-LiFePO4?
A: Ubushushu buchaphazela kakhulu i-voltage yebhetri ye-LiFePO4 kunye nokusebenza. Ngokubanzi, njengoko iqondo lokushisa liyancipha, i-voltage yebhetri kunye nomthamo wehla kancinci, ngelixa ukuchasana kwangaphakathi kuyanda. Ngokuchaseneyo, amaqondo obushushu aphezulu angakhokelela kumbane ophakamileyo kancinane kodwa anokunciphisa ubomi bebhetri ukuba bugqithisile. Iibhetri zeLiFePO4 zisebenza kakuhle phakathi kwe-20°C kunye ne-40°C (68°F ukuya kwi-104°F). Kwiqondo lokushisa eliphantsi kakhulu (ngaphantsi kwe-0 ° C okanye i-32 ° F), ukutshaja kufuneka kwenziwe ngononophelo ukuphepha i-lithium plating. Uninzi lweenkqubo zolawulo lwebhetri (BMS) zilungelelanisa iiparamitha zokutshaja ngokusekelwe kubushushu ukuqinisekisa ukusebenza ngokukhuselekileyo. Kubalulekile ukujonga iinkcukacha zomenzi wobudlelwane obuchanekileyo bobushushu-voltage yebhetri yakho yeLiFePO4.
