Isingeniso:
Amabhethri e-lithiumsesiyingxenye ebalulekile yokuphila kwethu kwansuku zonke, sinikeza amandla yonke into kusukela kuma-smartphones nama-laptops kuya ezimotweni zikagesi kanye nezinhlelo zokugcina amandla avuselelekayo. Emkhakheni wamabhethri e-lithium, kunezigaba ezimbili eziyinhloko: amabhethri e-voltage ephansi (LV) kanye namabhethri aphezulu (HV). Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamabhethri e-lithium kubalulekile ekukhetheni umthombo wamandla ofanele wohlelo oluthile.
Ibhethri ye-lithium ephansi (LV):
Amabhethri e-lithium ane-voltage ephansi ngokuvamile asebenza kuma-voltage angaphansi kuka-60V. Lawa mabhethri avame ukusetshenziswa kumishini kagesi ephathekayo, amathuluzi kagesi, namasistimu amancane okugcina amandla. Amabhethri anamandla aphansi aziwa ngosayizi wawo ohlangene, umklamo ongasindi kanye nokuminyana kwamandla aphezulu, okuwenza alungele izinhlelo zokusebenza lapho isikhala nesisindo kubaluleke kakhulu.
Amandla kagesi aphansiamabhethri e-lithiumnazo zaziwa ngezindleko zazo eziphansi uma kuqhathaniswa namabhethri ane-voltage ephezulu. Lokhu kubenza babe ukukhetha okudumile kuma-electronics abathengi nezinye izinhlelo zokusebenza zamandla aphansi. Ukwengeza, amabhethri ane-voltage ephansi kulula ukuwaphatha nokuyigcina ngenxa yamazinga aphansi kagesi, angenza kube lula ukuklama nokusebenzisa izinhlelo zokuphatha ibhethri.
Ibhethri ye-lithium ephezulu (HV):
Amandla kagesi aphezuluamabhethri e-lithiumube ne-voltage yokusebenza engaphezu kuka-60V. Lawa mabhethri avame ukusetshenziswa ezimotweni zikagesi, izinhlelo zokugcina amandla esikali segridi, nasezinhlelweni zezimboni ezidinga ukuphuma kwamandla aphezulu namandla. Amabhethri ane-voltage ephezulu aklanyelwe ukuletha ukusebenza okuphezulu nokusebenza kahle, okuwenza afanelekele ukufunwa kwezicelo zamandla aphezulu.
Omunye umehluko omkhulu phakathi kwamabhethri ane-low-voltage kanye ne-high-voltage ukuminyana kwawo kwamandla. Amabhethri anamandla kagesi aphezulu ngokuvamile anomthamo omkhulu wamandla kunamabhethri anamandla aphansi, okuwavumela ukuthi agcine amandla engeziwe phakathi kwevolumu noma isisindo esithile. Lokhu kubambana kwamandla okuphezulu kubalulekile ezinhlelweni ezifana nezimoto zikagesi, lapho ukukhulisa ibanga lokushayela kanye nokuphuma kwamandla kuyizici ezibalulekile.
Omunye umehluko obalulekile ubunkimbinkimbi besistimu yokuphatha ibhethri edingekayo kumabhethri ane-voltage ephezulu. Ngenxa yokuthi amabhethri anamandla kagesi anamazinga aphezulu kagesi namandla aphumayo, amasistimu okuphatha amabhethri ayinkimbinkimbi futhi anamandla ayadingeka ukuze kuqinisekiswe ukusebenza okuphephile nokusebenza kahle. Le nkimbinkimbi inyusa izindleko zizonke kanye nezinselele zobuchwepheshe ezihlotshaniswa nesistimu yebhethri enamandla amakhulu.
Ukucatshangelwa kokuphepha:
Kwa-lamabhethri athium, kungakhathaliseki ukuthi i-voltage ephansi noma ephezulu, ukuphepha kuyisici esibalulekile. Kodwa-ke, amabhethri anamandla kagesi adala izinselele ezengeziwe zokuphepha ngenxa yamazinga aphezulu kagesi namandla. Ukuphathwa ngendlela efanele, ukugcinwa, nokugcinwa kahle kwamabhethri anamandla kagesi aphakeme kubalulekile ukuze kuvinjwe izingozi ezingaba khona zokuphepha ezifana nokubaleka okushisayo, ukushajwa ngokweqile, namasekhethi amafushane.
Amabhethri anamandla aphansi, nakuba ngokuvamile ebhekwa njengaphephile ngenxa yamazinga kagesi aphansi, asadinga ukuphathwa nokunakekelwa okufanele ukuze kuncishiswe ubungozi bemicimbi yokushisa nezinye izinkinga zokuphepha. Kungakhathalekile izinga le-voltage, kubalulekile ukulandela imihlahlandlela yomkhiqizi kanye nezindlela ezihamba phambili zemboni zokusebenzisa ngokuphephile amabhethri e-lithium.
Umthelela endaweni ezungezile:
Kokubili i-low-voltage kanye ne-high-voltageamabhethri e-lithiumabe nomthelela emvelweni, ikakhulukazi ezinhlelweni zabo zokukhiqiza kanye nokulahlwa kokuphela kwempilo. Ukukhishwa nokucutshungulwa kwe-lithium nezinye izinto ezisetshenziswa ekukhiqizeni ibhethri kungaba nomthelela kwezemvelo, okuhlanganisa ukuqedwa kwensiza kanye nokungcola. Ukwengeza, ukugaywa kabusha nokulahlwa okufanele kwamabhethri e-lithium kubalulekile ukuze kuncishiswe indawo yawo yemvelo.
Uma uqhathanisa amabhethri aphansi-voltage kanye ne-high-voltage, kubalulekile ukucabangela umthelela wemvelo wokukhiqiza, ukusetshenziswa nokulahlwa kwawo. Amabhethri ane-voltage ephezulu angase abe nomthelela omkhulu endaweni ngenxa yobukhulu bawo obukhulu namandla aphezulu kunamabhethri ane-voltage ephansi. Kodwa-ke, intuthuko ekusetshenzisweni kabusha kwebhethri kanye nezinqubo zokukhiqiza eziqhubekayo ziyaqhubeka nokuthuthukisa ukusebenza kwemvelo kwamabhethri e-lithium.
Isiphetho:
Umehluko phakathi kwe-low-voltage kanye ne-high-voltageamabhethri e-lithiumzibalulekile futhi kufanele zicatshangelwe ngokucophelela lapho kukhethwa ibhethri lohlelo oluthile. Amabhethri anamandla aphansi alungele izinto zikagesi eziphathwayo, amathuluzi kagesi nesitoreji samandla amancane, anosayizi wawo ohlangene, umklamo ongasindi kanye nezindleko eziphansi. Amabhethri anamandla amakhulu, ngakolunye uhlangothi, aklanyelwe izinhlelo zokusebenza zamandla aphezulu njengezimoto zikagesi kanye nesitoreji samandla esikali segridi, enikeza ukuminyana kwamandla aphezulu nokusebenza.
Kungakhathaliseki ukuthi hlobo luni lwebhethri ye-lithium, izici zokuphepha nezemvelo kufanele zihlale zibekwe phambili. Ukuphatha kahle, ukugcinwa kanye nokulahlwa kwamabhethri e-lithium kubalulekile ukuze kuqinisekiswe ukusetshenziswa kwawo okuphephile nokuqhubekayo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukuthuthukisa amabhethri e-lithium ngokuphepha okuthuthukisiwe, ukusebenza kanye nokusimama kwemvelo kuzodlala indima ebalulekile ekubumbeni ikusasa lokugcina amandla kanye nokufakwa kukagesi.
