Manje, abantu abaningi ngokwengeziwe bancamela ukwenza i-DIY amaphakethe abo ebhethri ye-lithium. Empeleni, iphakethe lebhethri le-lithium le-DIY alinzima kakhulu, udinga kuphela ukuthenga zonke izesekeli ezidingekayo, landela izinyathelo ezingezansi, futhi ungakwazi ukuqedela umkhiqizo we-DIY uwedwa. Ngezansi, sithatha i 18650 iphakethe lebhethri njengesibonelo sokwabelana nawe ukuthi ulenza kanjani iphekhi yebhethri ye-lithium efektri.

Isibonelo sethu yiphakethe lebhethri le-lithium 48V17.5Ah, usebenzisa i-Samsung 18650 amaseli, indlela yokuhlanganisa 13 uchungechunge kanye 5 ngokuhambisana.

Inqubo yokuhlanganisa ngokuvamile ihlanganisa izinyathelo ezilandelayo：

Ukukhetha i-voltage evalwe kakhulu, ukumelana kwangaphakathi, namandla we 18650 amaseli abizwa nangokuthi iqoqo lokwabiwa.

Mayelana namandla, kungenzeka ukuthi ukufanisa sekuqediwe lapho indaba yamukelwe. Ngaphambi kokuhlanganisa iphakethe lebhethri, kudingekile kuphela ukuhlola i-voltage kanye nokumelana kwangaphakathi kwamaseli ebhethri.

Izinga elijwayelekile lokuhlola ukuthi umehluko we-voltage ungaphakathi kwe-5mV, futhi ukumelana kwangaphakathi kungaphakathi kwe-5mV. Umehluko ungaphakathi kuka-3mΩ.

Amaseli kuphela angaphakathi kobubanzi balo mehluko kagesi kanye nomehluko wokumelana wangaphakathi angahlanganiswa abe yisethi yamaphakethe ebhethri ye-lithium ukuze ukuvumelana kwamaphakethe ebhethri ahlanganisiwe kube ngcono., futhi ukusebenza kwamaphakethe ebhethri kuzoba ngcono. Izinto ezisetshenziswayo wumshini wokuhlunga nokuhlanganisa amaseli.

Indlela engcono kakhulu yokuhlanganisa iphakethe lebhethri ukubeka isibambi sikabakaki samaseli ebhethri ukuze ngemva kokuhlanganisa iphakethe lebhethri., kungaba khona abakaki phakathi kwamaseli ukuze ahlukaniselwe. Ngokuzihlukanisa phezulu, iphekhi yebhethri iphephe kakhudlwana futhi igwema ukudlidliza okuthinta ukuphepha kwephakethe lebhethri le-lithium.

Izinto ezisetshenziswa ekushiseleni indawo yi-nickel strip, ehlukaniswe yaba umugqa we-nickel omsulwa kanye nensimbi ene-nickel-plated. Intengo yezinhlamvu ze-nickel ehlanzekile izobiza kakhulu. Ngokuqhathanisa, intengo yamapheshana ensimbi ane-nickel ishibhe kakhulu, futhi ukungasebenzi kahle ukuthi ukumelana kwangaphakathi kukhudlwana, ikhono overcurrent liphansi, futhi maningi amathuba okuthi agqwale.

Ngobukhulu bomugqa we-nickel, izidingo zamanje zemikhiqizo evamile, ubukhulu bomucu we-nickel ngokuvamile bungu-0.15mm, ngakho amandla omshini wokushisela indawo afaneleka kakhulu. Uma yamanje incane uma kuqhathaniswa, ungasebenzisa umugqa we-nickel owugqinsi ongu-0.1mm, futhi uma umsinga mkhulu kakhulu, ungasebenzisa i-nickel strip engu-0.2mm. Imicu ye-nickel emincane kakhulu noma eminyene kakhulu ayinconywa.

Lapho i-spowelding, kuyadingeka ukunaka ukuhlola umphumela we-spot welding. Amandla omshini wokushisela indawo akufanele abe mancane kakhulu, okuzoholela ekushiseleni okubonakalayo kweseli, noma amandla omshini wokushisela indawo akufanele abe mkhulu kakhulu ukugwema ukuthosa noma ukushisela indawo yeseli. Ngemuva kwe-spot welding, ukuhlolwa okuqinile kwe-7KG kuzophasiswa.

I-BMS esetshenziswa i-ternary lithium 13 uchungechunge 48V lithium ibhethri BMS. Ukushiselwa kwe-BMS kumele kusekelwe ekucacisweni kwe-BMS. Umdwebo wencazelo yezintambo ubonisa ukushisela, kusuka ku-B-, B0, B1, esigabeni sokugcina, B13, zonke zidinga ukushiselwa ngokuya ngokucaciswa kwe-BMS.

Ngemva kokuhlanganisa izintambo ze-BMS, kuyadingeka ukuthi usebenzise imikhono eshwabene ukushisa ukuze uvale amalunga e-solder ukuvimbela amalunga e-solder ukuthi angafinyeleli futhi angasebenzi kahle..

Lesi sinyathelo esokwenza ukupakishwa kwe-insulation kanye nokubunjwa kwephakethe lebhethri, lungisa izintambo zephakethe lebhethri, futhi uwapakishe.

Ukuze uvale kangcono inqubo yokuhlanganisa iphakethe lebhethri le-lithium, iphakethe lebhethri lishaywa ngefilimu ye-PVC, futhi inamathiselwe kuzo zombili iziphetho ngemuva kwefilimu ye-PVC. Ukuvimbela amanzi nothuli, vikela kangcono iphakethe lebhethri le-lithium.

Lesi sinyathelo sidinga ukuxhuma izintambo eziveziwe zephakethe lebhethri kuzixhumi zezinto zegobolondo ze-casing, okuhlanganisa ukushaja nokukhipha amatheminali, ama-fuse, amaswishi, njll.

Ngokuvamile, yamanje yembobo yokushaja incane uma kuqhathaniswa, ngakho-ke i-diameter yocingo esetshenzisiwe incane kakhulu; kuyilapho i-current port yokukhipha inkulu kakhulu, ububanzi bocingo olusetshenzisiwe bukhulu kakhulu, ukuze i-overcurrent ibe ngcono kakhulu.

Ukusoda kwezintambo kudinga ukwenziwa ngokuya ngomdwebo wohlelo lokuxhumana phakathi kwephakethe lebhethri nekesi..

Ukuhlolwa kokugcina kwephakethe lebhethri le-lithium kufaka phakathi ukuhlolwa komjikelezo wokushaja, ukuhlolwa komthamo, ukuhlolwa kokumelana kwangaphakathi, ukuhlolwa kwe-voltage evulekile, ukuhlolwa kwe-overcurrent, ukuhlolwa kwe-overcharge, ukuhlolwa kokukhishwa ngokweqile, ukuhlolwa kwesifunda esifushane, njll.

Ukuze uqinisekise ukusebenza kwephakethe lebhethri, izinyathelo zokuhlola zidinga ukwenziwa into ngayinye ngokwezidingo zokusebenza zephakethe lebhethri. Izinto ezisetshenziswayo zihlanganisa ukushaja kwephakethe lebhethri le-lithium kanye nokukhipha ikhabethe eliguga, umhloli womkhiqizo wonke, ishaja, njalo njalo.
