Kodi pali kusiyana kotani pakati pa 21700 ndi 18650?

Kuchuluka kwa mphamvu ndi moyo wa batri Potengera kuchuluka kwa mphamvu, ngati 21700 ndi 18650 ndi mabatire opangidwa ndi mankhwala omwewo, mphamvu zawo zimakhala zofanana. M'malo mwake, ngati 21700 ndi 18650 sizinapangidwe ndi mankhwala omwewo, mphamvu zawo zimakhala zosiyana. Mwachitsanzo, kachulukidwe kagawo ka mphamvu zamabatire a lithiamu iron phosphate ndi otsika kuposa mabatire a ternary lithiamu. Pankhani ya moyo wa batri, ngati 21700 ndi 18650 ndi mabatire amtundu womwewo, ndiye kuti mabatire a 21700 ali ndi voliyumu yayikulu komanso mphamvu yapamwamba kuposa mabatire a 18650, ndipo mabatire a 21700 angapereke moyo wautali wautali. Ngati 21700 ndi 18650 ndi mitundu yosiyanasiyana ya mabatire, moyo wawo wa batri ukhoza kukhala wofanana ndi womwewo, ndiye kuti, mabatire a 18650 amagwiritsa ntchito mabatire amphamvu kwambiri, ndipo mphamvu ya batri ya kupanga kwawo ikhoza kukhala yokulirapo, yomwe ingathe kutero. kukhala pafupi ndi mphamvu ya 21700 lithiamu iron phosphate mabatire.

Mawonekedwe ogwiritsira ntchito ndikugwiritsa ntchito mabatire a 21700 nthawi zambiri amagwiritsidwa ntchito pazida zomwe zimafuna kusungirako mphamvu zambiri komanso moyo wautali wa batri, monga zosunga zobwezeretsera zadzidzidzi za UPS zamagetsi zamagalimoto amagetsi ndi zida zazikulu zamagetsi. Mabatire a 18650 amagwiritsidwa ntchito kwambiri pazida zing'onozing'ono monga tochi, zida zazing'ono zamagetsi ndi magalimoto ena amagetsi.

Kuvuta kwa mtengo ndi kugula Kwa cell imodzi ya batri (batire imodzi), popeza kuchuluka kwa mabatire a 21700 kungakhale kocheperako kuposa mabatire a 18650, komanso ngati mabatire amtundu womwewo, mabatire a 21700 ali ndi mphamvu zambiri ndipo amagwiritsa ntchito zofunika kwambiri. zida zopangira kuposa mabatire a 18650, kotero kuti mtengo wawo wopanga udzakhala wokwera, zomwe zingayambitse zovuta zogulira zinthu komanso mitengo yokwera pang'ono.

Kusiyanitsa pakati pa chiwerengero cha maselo ndi chiwerengero cha maselo Popeza m'mimba mwake 21700 batire ndi yaikulu ndipo akhoza kutengera mphamvu zambiri, chipolopolo chofunika pa m2 wa 21700 batire ndi 33% zochepa kuposa 18650 batire, kotero chipolopolo mtengo wa 21700 batire ndi yotsika kuposa ya 18650. Panthawi imodzimodziyo, popeza chiwerengero cha mabatire omwe ali ndi Wh omwewo amachepetsedwa ndi 33%, kufunikira kwa jekeseni wamadzimadzi ndi kusindikiza kumachepetsanso. Pankhani yopanga paketi yayikulu ya batri, mtengo wake umachepetsedwa.

Mapangidwe zida ndi bwino. Pamene kuchuluka kwa mabatire kukucheperachepera, kufunikira kwa zida zopangira kumachepetsedwanso kwambiri, zomwe zimapangitsa kuti magwiridwe antchito komanso kuchepetsa ndalama. Mwachidule, kusiyana pakati pa mabatire a 21700 ndi 18650 makamaka kumakhala kukula, mphamvu, kachulukidwe kamphamvu, mawonekedwe ogwiritsira ntchito, zovuta zogula, nyumba za batri ndi kuchuluka kwa batri, zida zopangira ndi magwiridwe antchito, ndi zina zambiri. ku zofunikira zenizeni za ntchito.
