Uyini umehluko phakathi kokusebenzisa umugqa we-nickel omsulwa kanye nensimbi ye-nickel plated lapho i-DIY lithium battery pack?

I-nickel strip iyinto evame ukusetshenziswa ochungechungeni futhi ihambisane namaphakethe ebhethri e-lithium. Ububanzi nempahla yomugqa we-nickel kufanele kukhethwe ngokuya ngokwamanje kwephakethe lebhethri le-lithium. Mayelana nempahla, kunemicu ye-nickel emibili evame ukusetshenziswa: imichilo ye-nickel ehlanzekile kanye nensimbi ene-nickel plated.

Uyini umehluko phakathi kokusebenza kwabo kanye nokusetshenziswa kwangempela? Ake siyihlaziye ngezansi.

1. Amandla wamanje:

Ukumelana kwangaphakathi kwemichilo ye-nickel ehlanzekile kuncane, futhi amandla adlulayo anamandla kunalawo ensimbi ene-nickel plated.

Ekusetshenzisweni okujwayelekile, ifomula yokubala ithi: umugqa we-nickel omsulwa ubala amandla we-overcurrent ngokuya ngo-10A/mm², njenge-nickel emsulwa enogqinsi luka-0.15mm*7mm ububanzi, isincomo saso esiphezulu esiqhubekayo sokudlulela phambili ngu-10*0.15*7=10.5A;

Ngensimbi ene-nickel-plated, ifomula yayo yokubala ivamise ukubalwa ngokuya nge-7A/mm², okusho ukuthi, i-overcurrent ephezulu eqhubekayo yensimbi e-nickel-plated enogqinsi luka-0.15mm*7mm ngu-7*0.15*7=7.35A.

Kungabonakala ukuthi okwamanje umugqa we-nickel ohlanzekile ongamelana nawo umayelana 1.5 izikhathi ezingaphezu kwe-nickel plated steel. Ngakho-ke, lapho umsinga ufana, i-nickel ehlanzekile ikhiqiza ukushisa okuncane.

Kunjalo, ifomula engenhla ingeyereferensi kuphela, amandla adlulele e-nickel strip nawo anqunywa ngokuya kwesikhathi sokuphuma kanye nesakhiwo sephakethe lebhethri..

2. Ukuzinza komkhiqizo:

Umugqa we-nickel omsulwa ungcono kunensimbi ene-nickel plated.

Umugqa we-nickel ohlanzekile unokumelana nokugqwala okuqinile. Ekuhlolweni kwesifutho sikasawoti, ukumelana nokugqwala kwemichilo ye-nickel emsulwa ngokusobala kungcono kunokwensimbi ene-nickel plated.

Uma iphakethe lebhethri le-lithium livame ukusetshenziswa endaweni enomswakama ophezulu, insimbi ye-nickel plated izogqwala kalula, kodwa amapheshana e-nickel ahlanzekile ngeke. Lokhu futhi kungenye yezinzuzo ezithandwayo zemicu ye-nickel ehlanzekile.

3. Spot welding:

Phakathi nenqubo yokupakisha, ukuxhumana phakathi kwemichilo ye-nickel namaseli zonke izindlela zokushisela endaweni yokumelana, njengamaseli angama-cylindrical, 18650/26650/32700, ngakho-ke kukhulu ukumelana kwangaphakathi kwe-nickel strip, kulapho umphumela wokushisela uba ngcono.

Ukumelana kwangaphakathi kwemichilo ye-nickel ehlanzekile kuncane, kuyilapho ukumelana kwangaphakathi kwe-nickel plated steel kukhulu. Ngakho-ke, mayelana nomphumela we-welding we-spot kanye nokuzinza okuqinile, insimbi ye-nickel plated inokwethenjelwa kakhulu. Kunjalo, umugqa we-nickel ohlanzekile ungenza futhi lesi sici esincane sangaphakathi sokumelana nesakhiwo, ukuqhathanisa indawo yokushisela ukuze uvule i-groove emise okwe-工 njalonjalo.

4. Inani:

Umugqa we-nickel omsulwa umayelana 3 izikhathi ezibiza kakhulu kune-nickel plated steel. Ngakho-ke uma ucabangela izindleko zephakethe lebhethri, abanye abantu bazobhekisa insimbi egcwele i-nickel ukuze behlise intengo yalo lonke iphakethe lebhethri le-lithium.
