Ukwandisa isikhathi sokuphila kanye nokusebenza kwamabhethri e-lithium-ion, imikhuba efanele yokushaja ibalulekile. Izifundo zakamuva nezincomo zezimboni ziqokomisa amasu ahlukile wokushaja ngezinhlobo ezimbili ezisetshenziswa kabanzi: amabhethri we-nithium noma we-ternary ye-lithium). Nakhu abasebenzisi okudingeka bazi:
Izincomo ezibalulekile
- Amabhethri we-ncm: Khoshwa ku90% noma ngezansiukusetshenziswa kwansuku zonke. Gwema amacala agcwele (100%) ngaphandle kokuthi kudingekile ohambweni olude.
- Amabhethri we-LFP: Ngenkathi kushaja nsuku zonke90% noma ngezansiilungele, amasonto onke egcwele
- khokhisa(100%) kuyadingeka ukuthi iphinda iqashe isimo se-State of Charge (SoC).
Kungani Kufanele Ugweme Izindleko Ezigcwele Amabhethri we-NCM?
1. Ingcindezi ephezulu ye-voltage isheshisa ukonakaliswa
Amabhethri we-NCM asebenza endaweni ephakeme ephezulu ye-voltage umkhawulo ngokuqhathaniswa namabhethri e-LFP. Ukushaja ngokugcwele la mabhethri azifaka lapho uphakamisa amazinga ama-voltage, asheshise ukusetshenziswa kwezinto ezisebenzayo eKathode. Le nqubo engenangqondo iholela ekulahlekelweni kwamandla futhi ifinyeze isikhathi sebhethri sonke.

Amaphakethe webhethri aqukethe amaseli amaningi anokungahambisani okuvela kwemvelo ngenxa yokuhlukahluka kokwehluka kanye nokungafani kwe-electrochemical. Lapho ishaja ku-100%, amaseli athile angakhulisa, ebangela ukucindezela okwenziwe kwasendaweni nokuwohloka. Ngenkathi amasistimu wokuphatha ibhethri (BMS) alinganiselayo ama-voltages weseli, ngisho nezinhlelo ezithuthukile kusuka kumikhiqizo eholayo efana noTesla noByd abakwazi ukuqeda ngokugcwele le ngozi.
3. Izinselelo Zokulinganisa Kwezomsondo
Amabhethri we-NCM abonisa ijika le-voltage volta, evumela ukulinganiselwa okunembile kwe-SO SO Som nge-Voltage Voltage (OCV). Ngokuphambene nalokho, amabhethri e-LFP agcina i-voltage volta ecishe ibe yi-15% ne-95% SoC, okwenza ukufundwa kwe-OCV-based Me Soct akuthembekile. Ngaphandle kwezindleko ezigcwele ngezikhathi ezithile, amabhethri e-LFP alwela ukuphinda abuye abuye aqalise amanani abo emphakathini. Lokhu kungaphoqa i-BMS ibe izindlela zokuvikela njalo, ukusebenza okulimazayo kanye nempilo yebhethri yesikhathi eside.
Kungani amabhethri e-LFP adinga izindleko ezigcwele masonto onke
Imali ekhokhwa njalo ngeviki amabhethri we-LFP isebenza njenge- "Setha kabusha" ye-BMS. Le nqubo ilinganisa ama-voltages cell cell futhi ilungisa ama-SOC angcuracies abangelwa yiphrofayili yawo yamandla aqinile. Imininingwane ye-SOC eqondile ibalulekile kwi-BMS ukwenza izinyathelo zokuvikela ngempumelelo, njengokuvimbela ukuphuma ngokweqile noma ukuthuthukisa imijikelezo yokushaja. Ukweqa lokhu kulinganiswa kungaholela ekugugeni ngaphambi kwesikhathi noma ekusebenzeni okungalindelekile kwehla.
Imikhuba emihle yabasebenzisi
- Abanini bebhethri be-NCM: Phakamisa amacala ngokwengxenye (≤90%) bese ubeka izindleko eziphelele zezidingo ngezikhathi ezithile.
- Abanini bebhethri be-LFP: Gcina ukushaja kwansuku zonke ngaphansi kwama-90% kepha qinisekisa umjikelezo ogcwele weviki onke.
- Bonke abasebenzisi: Gwema ukukhishwa okujulile okujulile kanye namazinga okushisa aphezulu okuqhubeka nokunweba impilo yebhethri.
Ngokwamukela la masu, abasebenzisi bangakhulisa kakhulu ukuqina kwebhethri, banciphise ukucekelwa phansi kwesikhathi eside, futhi baqinisekise ukusebenza okuthembekile kwezimoto zikagesi noma izinhlelo zokugcina amandla.
Hlala unolwazi ngezibuyekezo zakamuva zobuchwepheshe bebhethri kanye nemikhuba yokusimama ngokubhalisela i-newsletter yethu.
