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.
