Ungakhetha kanjani ishaja yebhethri ye-lithium-ion yekhwalithi enhle? Izinga leshaja linqume ubude bempilo yebhethri ye-lithium-ion, ngakho ukukhetha ishaja yekhwalithi kubaluleke kakhulu. I-voltage ephumayo yeshaja kufanele ihambisane nebhethri lakho, lokhu kufanele kubambe okunembile. Ungakhetha kanjani ishaja yebhethri ye-lithium-ion yekhwalithi enhle? 1.

Uma ukushaja kukhudlwana, isivinini sokushaja siyashesha. Ubude besikhathi sokushaja buhlobene nesivinini sokushaja, futhi sibheke nomthamo wamabhethri e-lithium-ion. Kufanele kuqashelwe ukuthi lapho ukushaja kukhudlwana, ziba ziphezulu izidingo zekhwalithi yedizayini yedizayini yesistimu yangaphakathi yeshaja nebhethri ye-lithium-ion.

Ngokuvamile, uma ibhethri lilikhulu, ukushisa okukhulu ngesikhathi sokushaja, umonakalo omkhulu ekusebenzeni kwebhethri. Ishaja Yokuhlanza Ikhwalithi kanye Nebhethri Kulula ukuba nokusebenza okuphephile njengoketshezi oluvuzayo lapho ishajwa ngokushesha. 2 Njalo ngaphansi kuka-100%.

Lapho ishaja, i-chargency yokushaja kufanele ilawulwe ngaphakathi kwebanga elithile, futhi i-chargency yokushaja inkulu kakhulu noma incane kakhulu, okuzonciphisa ukusebenza kahle kokushaja. Mayelana neshaja esheshayo yamanje enkulu, kuyadingeka ukwenza umklamo okhethekile wendlela yokushaja yeshaja yebhethri ye-lithium ion ukuze kuthuthukiswe ukusebenza kahle kokushaja. 3.

Buka ishaja yeshaja ukuze ivale ishaja yamanje encane evame ukusebenzisa indlela yokulawula isikhathi. Uma kukhulu ukutholakala kweshaja kwamanje, kuba nzima kakhulu indlela yokulawula ukuvala ukushaja, kulapho izindleko kanye nentengo ziphezulu. Kumsebenzisi, ukukhetha ngokuya ngesimo sakho sangempela.

Uma umthamo webhethri osetshenzisiwe ungekho phezulu kakhulu, noma isivinini sokushaja singabizi kakhulu, inkokhiso evamile ingakhethwa; uma kunesidingo, kunesidingo sokukhetha ishaja esheshayo, kungcono ukuba nokusebenza okwengeziwe kweshaja nebhethri ye-lithium-ion. Yiba nokuqonda okuthile. 4.

Ukwahlulela ishaja yemoto kagesi yekhwalithi yeshaja ubuchwepheshe bokushaya kwenhliziyo obuhle nobunegethivu, obungakwazi ukugada, ukuvimbela, ukuqeda ukonakala kwebhethri, kanye nokwehlukanisa. Umthamo webhethri omusha ungagcinwa isikhathi eside futhi uzinzile; i-polarized, umthamo womthamo webhethri endala uyabuyiselwa, futhi impilo yebhethri inwetshwa izikhathi ezi-2 kuya kwezi-3 kunempilo yebhethri. Iba nokuvikela okuhlakaniphile ngesikhathi, umsebenzi wesinxephezelo esizenzakalelayo sezinga lokushisa, ukuvikelwa komthelela osheshayo wegridi, ukumelana nokugqwala kokuvimbela i-super anti-tide, njll.

I-5, ulayini wokushaja wocingo wokushaja nawo uyafana, kungcono ukusebenzisa ikhebula lokushaja langempela noma le-suite. Uma kuyikhebuli yokushaja efanayo, kufanele ifakwe ngaphezulu ukuze kugwenywe ukuxutshwa. Isistimu yokushaja ibhethri ye-lithium-ion inaka umthombo wokufaka: Abaningi basebenzisa ama-adaptha odongeni ashibhe kakhulu njengamandla okufaka.

I-voltage yayo yokuphuma ibalulekile ukuncika ku-voltage yokufaka ye-AC kanye nokulayisha okwamanje ogeleza usuka ku-adaptha yodonga. Izinga nokunemba kokushaja kwamanje okungaguquki: Ukukhethwa kwe-topology yokusetshenziswa okukhethekile kungase kunqunywe ngokushaja kwamandla. Amashaja amaningi amanje amakhulu angashintshi noma ukushajwa kwebhethri okunezigaba eziningi kusebenzisa izindlela zokucubungula ukushaja ukuze kuzuzwe ukusebenza kahle okuphezulu nokuvikela ukushisa okukhulu.

Ukunemba kokuqina kwe-voltage ephumayo: Ukuze usebenzise umthamo webhethri ngangokunokwenzeka, ukunemba kwesilawuli se-voltage ephumayo kubaluleke kakhulu. Ukwehla okuncane kwe-amplitude ekunembeni kwe-voltage ephumayo nakho kungabangela ukuncipha okukhulu komthamo webhethri ye-lithium-ion. Kodwa-ke, ngenxa yokuphepha nokuthembeka, i-voltage ephumayo ayikwazi ukumiswa phezulu ngokuthanda kwakho.

Ukuqapha izinga lokushisa lebhethri: Ngaphansi kwezimo ezijwayelekile, izinga lokushisa ku-0 ¡ã C kuya ku-45 ¡ã C phakathi nokushajwa kwebhethri le-lithium ion. Ukushaja ibhethri kungabangela ukushisa kwebhethri kuleli banga. Emjikelezweni wokushaja, ukunyuka kwengcindezi ebhethrini kuzodala ukuthi ibhethri likhule.

Izinga lokushisa nepeni lokucindezela. Okungenhla ukukhetha kweshaja yebhethri ye-lithium-ion. Ukuqaphela ukuthi inqubo yokushaja yebhethri ye-lithium-ion ihluke ngokuphelele kunqubo yokushaja yamabhethri e-nickel-cadmium kanye ne-nickel-hydrogen.

Kuyinqubo eyinkimbinkimbi yokusabela kwe-electrochemical. Ngakho-ke ukulungisa ishaja ezinikele ukuze ishaje.
