Mafunso Ofunsidwa Kawirikawiri

Kodi ndingagwiritse ntchito banki yamagetsi ya USB ndi jekete lotenthetsera?
Pokhapokha ngati jekete lotenthetsera lapangidwira makamaka 5V USB input. Majekete ambiri otenthetsera akatswiri amagwira ntchito pa 7.4V ndipo amagwiritsa ntchito zolumikizira zapadera - kulumikiza banki yamagetsi ya USB mu jekete la 7.4V sikungagwire ntchito ndipo kungawononge chowongolera. Majekete ambiri otenthetsera a OEM amapangidwira mapaketi a batri a 7.4V chifukwa makina a 5V sangathe kupereka mphamvu zokwanira kuti kutentha kutenthe bwino. Ngati kusavuta kwa 5V USB ndikofunikira pa malo anu, kambiranani ndi wopanga wanu koyambirira - kumafuna kapangidwe kosiyana ka chowongolera ndi chosinthira chamkati, chomwe chimawonjezera mtengo ndikuyambitsa kutayika kwa magwiridwe antchito.
Kodi ndi mabatire angati owonjezera omwe ndiyenera kuyitanitsa pa jekete lililonse kwa makasitomala amakampani?
Pa ntchito yonse (maola 8-12), tikupangira batire imodzi yowonjezera pa jekete lililonse, kotero wantchito aliyense ali ndi mabatire awiri: limodzi likugwiritsidwa ntchito, limodzi likuchajidwa. Batire yoyamba imapereka maola 3-5 pa sing'anga, ndipo yowonjezera imaphimba nthawi yotsala ya sing'anga. Pa ntchito zomwe zimafuna kutentha kosalekeza tsiku lonse pa sing'anga kapena yapamwamba, ganizirani kusankha mabatire okhala ndi mphamvu yowonjezereka (7,500-10,000 mAh) omwe amatha kupereka maola 8-12 pa sing'anga popanda kusinthana kwa batire. PASSION OUTERWEAR imapereka mtengo wa batire yochuluka pamene mabatire ayitanidwa pamodzi ndi majekete.
Kodi mabatire a jekete lotenthedwa amataya mphamvu akasungidwa kwa nthawi yayitali?
Inde — mabatire a lithiamu-ion amadzitulutsa okha pa 2-3% pamwezi kutentha kwa chipinda. Pachifukwa ichi, mabatire ayenera kuyikidwa chaji pafupifupi 50-60% asanasungidwe kwa nthawi yayitali (miyezi itatu kapena kupitirira). Kusunga batire yodzaza kapena yodzaza kwathunthu kwa nthawi yayitali kumathandizira kuwonongeka kwa mphamvu. Kwa ogula a B2B omwe ali ndi zinthu zanyengo, tikupangira kuphatikiza pepala losungira batire ndi malangizo ochajira ndi chinthu chilichonse kuti muchepetse kuwonongeka kwa batire nthawi zina. Ma circuit amakono a BMS ali ndi njira yosungira mphamvu zochepa yomwe imachepetsa kutulutsa kwa batire pansi pa 2.5V cutoff.
Kodi kusiyana pakati pa batire ya 5,000 mAh ndi batire ya 10,000 mAh ndi kotani kwenikweni?
Batire ya 10,000 mAh 7.4V imasunga mphamvu ya 74 Wh, pafupifupi kawiri 37 Wh ya paketi ya 5,000 mAh. Mwachidule, izi zikutanthauza kuwirikiza kawiri nthawi yogwiritsira ntchito pa kutentha kulikonse. Komabe, paketi ya 10,000 mAh ndi yayikulu komanso yolemera (nthawi zambiri 180-220g poyerekeza ndi 100-120g ya paketi ya 5,000 mAh), yomwe imafuna thumba lalikulu la batri mu chovalacho. Pa ntchito zambiri za B2B, muyezo wa 5,000 mAh ndiye mulingo woyenera wa nthawi yogwiritsira ntchito komanso chitonthozo. Mapaketi akuluakulu ndi oyenera kugwiritsidwa ntchito tsiku lonse m'mafakitale komwe kutentha kwambiri kumafunika ndipo wogwiritsa ntchito ali wokonzeka kulandira kulemera kowonjezera.
Kodi ndingatumize majekete otentha okhala ndi mabatire oyikidwa ndi ndege yonyamula katundu?
Mabatire a Lithium amalamulidwa ngati katundu woopsa woyendera pandege. Mabatire omwe amaikidwa muzipangizo (UN 3481, PI 967 Gawo II) amakumana ndi zoletsa zochepa kuposa mabatire odziyimira pawokha, koma amafunikirabe satifiketi ya UN 38.3, Chilengezo cha Wotumiza Zinthu Zoopsa, ndi kulongedza malinga ndi malamulo a IATA. Majekete ambiri otenthedwa a B2B amayenda ndi katundu wapanyanja, omwe ali ndi zoletsa zochepa komanso mtengo wotsika. Pa katundu wa pandege, gwirani ntchito ndi wotumiza katundu wodziwa bwino kutumiza mabatire a lithiamu ndikuwonetsetsa kuti fakitale yanu ikupereka zikalata zonse za UN 38.3 ndi MSDS pa kasinthidwe kalikonse ka batire.
