Umongo wemboni: uchungechunge lokuhlinzekwa kwebhethri lezingubo ezishisayo

Iningi labakhiqizi bezingubo ezishisayo abenzi amabhethri ngaphakathi. Bathola amaphakethe ebhethri aqediwe kubahlanganisi bephakethe lebhethri abakhethekile, abathola amaseli avela kubakhiqizi abakhulu bamaseli e-lithium-ion. Indima yomkhiqizi ukuhlanganiswa — ukuqinisekisa ukuthi ibhethri lihambisana kahle nezinto zokushisa, ligcinwe kahle ephaketheni elinokuphathwa kwekhebula, futhi liqinisekiswe ngokugcwele. Ikhwalithi yefektri ekuhlanganisweni kwebhethri ibonakala emibhalweni yayo yokuhlola, hhayi ezimangalweni zokukhiqiza ibhethri uqobo. Ukucaca mayelana nochungechunge lokuhlinzeka kuyisibonakaliso somhlinzeki ochwepheshe.

imibuzo ejwayelekile ukubuzwa

Ngingasebenzisa noma yiliphi ibhange lamandla le-USB ngejakethi elifudumele?
Kuphela uma ijakethi elifudumele lenzelwe ngqo okokufaka kwe-5V USB. Iningi lamajakethi afudumele ochwepheshe asebenza ku-7.4V futhi asebenzisa izixhumi ezizimele — ukufaka ibhange lamandla le-USB kujakethi le-7.4V ngeke kusebenze futhi kungalimaza isilawuli. Iningi lamajakethi afudumele e-OEM lenzelwe amaphakethe ebhethri e-7.4V azinikele ngoba izinhlelo ze-5V azikwazi ukuletha amandla anele okushisa okuphumelelayo. Uma ukusebenziseka kalula kwe-5V USB kubalulekile ekubekeni umkhiqizo wakho endaweni, xoxa ngakho nomkhiqizi wakho kusenesikhathi — kudinga ukwakheka okuhlukile kwesilawuli nge-converter yangaphakathi yokukhulisa, enezela izindleko futhi ilethe ukulahlekelwa kokusebenza kahle.
Mangaki amabhethri asele okufanele ngiwa-ode ngejakhethi ngayinye kumakhasimende ebhizinisi?
Uma usebenzisa ishifti ephelele (amahora angu-8-12), sincoma ibhethri elilodwa elisele ngejakhethi ngayinye, ngakho-ke isisebenzi ngasinye sinamabhethri amabili: elilodwa elisebenzayo, elilodwa elishaja. Ibhethri eliyinhloko linikeza amahora angu-3-5 uma liphakathi nendawo, kanti elisele limboza ingxenye esele yeshifti. Ngezinhlelo zokusebenza ezidinga ukushisa okuqhubekayo usuku lonke kuzilungiselelo eziphakathi nendawo noma eziphezulu, cabanga ngokucacisa amabhethri anomthamo owengeziwe (7,500-10,000 mAh) anganikeza amahora angu-8-12 uma liphakathi nendawo ngaphandle kokushintshaniswa kwebhethri. I-PASSION OUTERWEAR inikeza intengo yebhethri elikhulu uma amabhethri e-odwa eceleni kwamajakhethi.
Ingabe amabhethri ejakethi afudumele alahlekelwa ukushaja ngesikhathi sokugcina isikhathi eside?
Yebo — amabhethri e-lithium-ion ayazikhipha cishe ku-2-3% ngenyanga ekushiseni kwegumbi. Ngenxa yalesi sizathu, amabhethri kufanele ashajwe cishe ku-50-60% ngaphambi kokugcina isikhathi eside (izinyanga ezi-3+). Ukugcina ibhethri lishajwe ngokugcwele noma likhishwe ngokugcwele isikhathi eside kusheshisa ukwehla kwamandla. Kubathengi be-B2B abaphethe isitoko sesizini, sincoma ukufaka ishidi lemiyalelo yokugcina ibhethri kanye nokushaja ngomkhiqizo ngamunye ukuze kuncishiswe izimangalo zomonakalo webhethri ongekho ngesikhathi sonyaka. Amasekethe e-BMS anamuhla afaka imodi yokugcina amandla aphansi enciphisa ukukhishwa kwayo ngaphansi komkhawulo we-2.5V.
Uyini umehluko phakathi kwebhethri elingu-5,000 mAh nebhethri elingu-10,000 mAh ngokwezinto ezingokoqobo?
Ibhethri elingu-10,000 mAh 7.4V ligcina cishe amandla angu-74 Wh, cishe kabili u-37 Wh wephakethe elingu-5,000 mAh. Ngokwendlela engokoqobo, lokhu kusho ukuthi cishe kabili isikhathi sokusebenza kunoma yisiphi isethingi sokushisa esinikeziwe. Kodwa-ke, iphakethe elingu-10,000 mAh likhulu ngokomzimba futhi lisindayo (ngokuvamile liyi-180-220g vs 100-120g lephakethe elingu-5,000 mAh), elidinga iphakethe lebhethri elikhulu engutsheni. Eziningi zezinhlelo zokusebenza ze-B2B, indinganiso engu-5,000 mAh iyibhalansi efanele yesikhathi sokusebenza kanye nenduduzo. Amaphakethe amakhulu afaneleka kakhulu ukusetshenziswa kwezimboni usuku lonke lapho kudingeka khona izilungiselelo zokushisa eziphakeme futhi umsebenzisi uzimisele ukwamukela isisindo esengeziwe.
Ngingakwazi yini ukuthumela amajakethi afudumele anamabhethri afakwe yi-air shipment?
Amabhethri e-lithium alawulwa njengezimpahla eziyingozi zokuthuthwa emoyeni. Amabhethri afakwe emishinini (UN 3481, PI 967 Section II) abhekene nemikhawulo embalwa kunamabhethri azimele, kodwa asadinga isitifiketi se-UN 38.3, iSimemezelo Somthumeli Wezimpahla Eziyingozi, kanye nokupakisha ngokwemithetho ye-IATA. Iningi lokuthunyelwa kwe-B2B kwamajakethi afudumele kuhamba ngempahla yolwandle, okunemikhawulo embalwa kanye nezindleko eziphansi. Ngokuthuthwa emoyeni, sebenza nomthumeli wempahla onolwazi ekuthuthweni kwebhethri le-lithium futhi uqinisekise ukuthi ifektri yakho inikeza imibhalo ephelele ye-UN 38.3 kanye ne-MSDS yokucushwa kwebhethri ngakunye. I-PASSION OUTERWEAR ifaka imibhalo ephelele yokuthunyelwa nayo yonke i-oda.
Ngingazi kanjani ukuthi amaseli ebhethri ayi-Tier-1 yangempela?
Amaseli e-Genuine Tier-1 (Samsung, LG, Panasonic) anesisindo esifanayo, ukubekezelelana okunembile kobukhulu, izimpawu zomkhiqizi ku-cell wrapper, kanye namakhodi e-batch alandelekayo. Amaseli e-counterfeit avamile emakethe futhi afana ngokubonakalayo. Izindlela zokuqinisekisa: (1) cela ishidi ledatha leseli bese uqinisekisa ukuthi imininingwane ihambisana nedatha ye-OEM eyaziwayo, (2) sikala amaseli — amaseli eqiniso angu-18650 avela kubakhiqizi abakhulu anesisindo esibikezelwayo ngaphakathi kokubekezelelana okungu-1-2g, (3) vivinya umthamo wangempela wokukhipha ngokumelene nencazelo elinganiselwe usebenzisa i-analyzer yebhethri, (4) sebenzisana nabakhiqizi abazoqamba umhlinzeki wabo weseli futhi banikeze imibhalo yokulandelela. Kwa-PASSION OUTERWEAR, sinikeza ukulandelelwa kwamaseli kanye namashidi edatha njengokujwayelekile ngama-oda ebhethri le-OEM.
