Indlela yokuqikelela uBomi beNkonzo ye-12V 100Ah LiFePO4 Ibhetri
Iinkcazo zeengcamango
- Ubomi bebhayisikile:Kucingelwa ukuba inani lemijikelo yebhetri esetyenziswayo ngonyaka imisiwe. Ukuba sithatha umjikelo omnye wokukhutshwa kwentlawulo ngosuku, ngoko ke inani lemijikelo ngonyaka limalunga nama-365 imijikelo. Ngoko ke, imijikelo eyi-5000 yokukhupha intlawulo epheleleyo iya kuhlala malunga neminyaka eyi-13.7 (imijikelo eyi-5000 ÷ 365 imijikelo/ngonyaka).
- Ubomi beKhalenda:Ukuba ibhetri ayizange iqhube imijikelezo epheleleyo yokuhlawulela, ngoko ubomi bayo bekhalenda buba yinto ephambili. Ukunikezelwa kobomi bekhalenda yebhetri yeminyaka eli-10, ibhetri ingahlala iminyaka eyi-10 nangaphandle kwemijikelo yokukhupha intlawulo.
Ukuqikelela ukubala:
- Ubomi bomjikelo webhetri yi-5000 epheleleyo imijikelo yokukhupha intlawulo.
- Ubomi bekhalenda yebhetri yiminyaka eyi-10.
Uxolo ngokuphazamiseka. Masiqhubeke:
Okokuqala, sibala inani lemijikelezo yokukhutshwa kwentlawulo ngosuku. Ukuthatha umjikelo omnye wokukhutshwa kwentlawulo ngosuku, inani lemijikelo ngosuku yi-1.
Emva koko, sibala inani lemijikelezo yokukhutshwa kwentlawulo ngonyaka: iintsuku ezingama-365 / unyaka × 1 umjikelo / usuku = 365 imijikelezo / ngonyaka.
Emva koko, sibala ubomi benkonzo eqikelelweyo: i-5000 i-charge-discharge cycles ÷ 365 imijikelezo / ngonyaka ≈ iminyaka eyi-13.7.
Ekugqibeleni, siqwalasela ubomi bekhalenda yeminyaka eyi-10. Ngoko ke, sithelekisa ubomi bomjikelezo kunye nobomi bekhalenda, kwaye sithatha ixabiso elincinci njengobomi benkonzo eqikelelweyo. Kule meko, ubomi benkonzo obuqikelelweyo buyiminyaka eyi-10.
Ngalo mzekelo, unokuqonda ngcono indlela yokubala ubomi obuqikelelweyo benkonzo ye-12V 100Ah LiFePO4 ibhetri.
Ewe kunjalo, nantsi itheyibhile ebonisa ubomi benkonzo obuqikelelweyo obusekwe kwimijikelo eyahlukeneyo yokukhupha intlawulo:
| Ii-Cycles zokukhupha intlawulo ngosuku | Imijikelo yokukhupha intlawulo ngonyaka | Ubomi obuqikelelweyo beNkonzo (uBomi boMjikelo) | Ubomi beNkonzo obuqikelelweyo (uBomi beKhalenda) | Ubomi beNkonzo obuqikelelweyo bokugqibela |
|---|---|---|---|---|
| 1 | 365 | 13.7 iminyaka | I-10 iminyaka | I-10 iminyaka |
| 2 | 730 | 6.8 iminyaka | 6.8 iminyaka | 6.8 iminyaka |
| 3 | 1095 | 4.5 iminyaka | 4.5 iminyaka | 4.5 iminyaka |
| 4 | 1460 | 3.4 iminyaka | 3.4 iminyaka | 3.4 iminyaka |
Le theyibhile ibonisa ngokucacileyo ukuba njengoko inani lemijikelezo yokukhutshwa kwentlawulo ngosuku landa, ubomi benkonzo obuqikelelwayo buyancipha ngokufanelekileyo.
Iindlela zeNzululwazi zokwandisa uBomi beNkonzo yeLiFePO4 yebhetri
- Ubunzulu boLawulo lokuKhupha:Ukunciphisa ubunzulu bokukhutshwa komjikelo ngamnye kunokwandisa kakhulu ubomi bebhetri. Ukulawula ubunzulu bokukhutshwa (DoD) ukuya ngaphantsi kwe-80% kunokunyusa ubomi bomjikelezo ngaphezu kwe-50%.

- Ulawulo lobushushu:Ukusebenzisa ibhetri phakathi komgangatho ofanelekileyo wobushushu kunokucothisa ukuguga kwebhetri. Ngokubanzi, ukugcina ubushushu obuphakathi kwe-20°C kunye ne-25°C yeyona nto ilungileyo. Rhoqo nge-10°C ukonyuka kobushushu, ubomi bebhetri bunokuhla nge-20% ukuya kwi-30%.
- ULondolozo lwarhoqo:Ukutshaja okulinganayo rhoqo kunye nokubeka esweni ubume bebhetri kunceda ukugcina ibhalansi yeeseli ezingaphakathi kwipakethi yebhetri kwaye kwandise ubomi bebhetri. Umzekelo, ukulinganisa ukutshaja rhoqo kwiinyanga ezi-3 kunokwandisa ubomi bomjikelezo webhetri nge-10% ukuya kwi-15%.
- Imeko-bume yokuSebenza eLungileyo:Kuphephe ukubeka ibhetri kwixesha elide lobushushu obuphezulu, ukufuma okuphezulu, okanye ingqele egqithisileyo. Ukusebenzisa ibhetri kwiimeko ezifanelekileyo zokusingqongileyo kunceda ukugcina ukusebenza okuzinzileyo kunye nokwandisa ubomi bayo.
Ngokuphumeza le milinganiselo, ubomi benkonzo ye-lithium iron phosphate Ibhetri inokunyuswa.
