Kodi mndandanda wa batri la lithiamu ndi kulumikizana kofananira, mndandanda ndi zolumikizana zofananira

Mu paketi ya batri ya lithiamu, angapomabatire a lithiamuamalumikizidwa mndandanda kuti apeze voteji yofunikira yogwira ntchito. Ngati mukufuna mphamvu apamwamba ndi apamwamba panopa, muyenera kulumikiza mphamvu lifiyamu mabatire mu kufanana, nduna ukalamba wa lifiyamu batire msonkhano zida akhoza kudziwa mkulu voteji ndi mkulu mphamvu muyezo pophatikiza njira ziwiri za mndandanda ndi kugwirizana kufanana.

1, mndandanda wa batri la lithiamu ndi njira yolumikizirana

Kulumikizana kofanana kwamabatire a lithiamu: magetsi sasintha, mphamvu ya batri imawonjezeredwa, kukana kwamkati kumachepetsedwa, ndipo nthawi yoperekera mphamvu imatha kukulitsidwa.

Kulumikizana kwa mndandanda wa batri ya lithiamu: voteji imawonjezeredwa, mphamvu ndi yosasinthika.Kulumikizana kwa Parallel kuti mupeze mphamvu zambiri, mukhoza kulumikiza mabatire angapo mofanana.

Njira ina yolumikizira mabatire mofanana ndiyo kugwiritsa ntchito mabatire akuluakulu, popeza pali mabatire ochepa okha omwe angagwiritsidwe ntchito ndipo njirayi si yoyenera kwa mapulogalamu onse.

Kuphatikiza apo, ma cell akulu sali oyenera mawonekedwe omwe amafunikira mabatire apadera. Ma chemistry ambiri a batri amatha kugwiritsidwa ntchito mofanana, ndimabatire a lithiamundi oyenera kugwiritsidwa ntchito limodzi.

Mwachitsanzo, kulumikizana kofanana kwa ma cell asanu kumasunga mphamvu ya batri pa 3.6V ndikuwonjezera nthawi yapano ndi yothamanga ndi kasanu. Ma cell a impedance kapena "otseguka" amakhala ndi mphamvu zochepa pamagawo ofananirako kuposa kulumikizana kwa mndandanda, koma batire yofananira imachepetsa kuchuluka kwa katundu ndikuthamanga nthawi.

Mukamagwiritsa ntchito maulalo otsatizana ndi ofanana, kapangidwe kake kamakhala kosavuta kuti akwaniritse ma voliyumu ndi mavoti apano omwe amafunikira kukula kwa batri.

Kuyenera kudziŵika kuti okwana mphamvu sasintha chifukwa cha njira zosiyanasiyana kugwirizana kwa lifiyamu batire malo welders kwa lifiyamu batire kupanga.

Mphamvu ndi yofanana ndi magetsi ochulukitsidwa ndi panopa. Zamabatire a lithiamu, mndandanda ndi njira zolumikizirana zofanana ndizofala. Imodzi mwa mapaketi a batri omwe amagwiritsidwa ntchito kwambiri ndi batri ya lithiamu ya 18650, yomwe ili ndi dera loteteza, ndi bolodi loteteza batire la lithiamu.

Gulu loteteza batire la lithiamu limatha kuyang'anira batire iliyonse yolumikizidwa mndandanda, kotero kuti mphamvu yake yayikulu kwambiri ndi 42V. Dongosolo loteteza batire la lithiamu (ie lithiamu batire yoteteza bolodi) litha kugwiritsidwanso ntchito kuwunika momwe batire iliyonse yolumikizidwa mndandanda.

Pogwiritsa ntchito 18650mabatire a lithiamumndandanda, zofunika zotsatirazi ziyenera kutsatiridwa: voteji iyenera kukhala yosasinthasintha, kukana kwamkati sikuyenera kupitirira 5 milliamp, ndipo kusiyana kwa mphamvu sikuyenera kupitirira 10 milliamp. Zina ndikusunga malo olumikizira mabatire oyera, Malo aliwonse olumikizira amakhala ndi kukana kwina. Ngati mfundo zolumikizira sizili zoyera kapena zolumikizira zikuwonjezeka, kukana kwamkati kungakhale kwakukulu, komwe kungakhudze magwiridwe antchito a batire yonse ya lithiamu.

2, lithiamu batire mndandanda-parallel kugwirizana chenjezo

General ntchitomabatire a lithiamumndandanda ndi kufanana ayenera kuchita lithiamu batire selo pairing, pairing miyezo: lithiamu batire selo voltage kusiyana ≤ 10mV, lithiamu batire selo mkati kukana kusiyana ≤ 5mΩ, lithiamu batire selo mphamvu kusiyana ≤ 20mA.

Mabatire ayenera kulumikizidwa limodzi ndi mtundu womwewo wa batire. Mabatire osiyanasiyana amakhala ndi ma voltages osiyanasiyana, ndipo akalumikizidwa molumikizana, mabatire okhala ndi ma voltages apamwamba amawongolera mabatire ndi ma voltages otsika, mphamvu yowononga.

Mabatire otsatizana ayeneranso kugwiritsa ntchito batire lomwelo. Kupanda kutero, mabatire amitundu yosiyanasiyana akalumikizidwa pamndandanda (mwachitsanzo, mabatire amtundu womwewo wokhala ndi milingo yosiyanasiyana yautsopano ndi ukalamba), batire yokhala ndi mphamvu yaying'ono idzatulutsa kuwala koyamba, ndipo kukana kwamkati kudzawonjezeka, panthawi yomwe batire yokhala ndi mphamvu yayikulu idzatulutsidwa kudzera mu kukana kwamkati kwa batire yokhala ndi mphamvu yaying'ono, kuwononga magetsi, komanso kuyibwezanso. Kotero voteji pa katunduyo adzachepetsedwa kwambiri, ndipo sangathe kugwira ntchito, mphamvu ya batri ndi yofanana ndi mphamvu yaing'ono ya batri.
