Isimiso sepuleti lokuvikela iphakethe lebhethri le-lithium-ion

Amabhethri e-lithium-ion aqediwe ahlanganisa izingxenye ezimbili ezibalulekile, amaseli ebhethri e-lithium-ion namapuleti okuvikela.

Ibhodi yokuvikela ibhethri ye-Lithium-ion iyisivikelo sokushaja nokukhipha uchungechunge lwephakethe lebhethri le-lithium-ion; ingaqinisekisa ukuthi umehluko we-voltage phakathi kweseli ngayinye ingaphansi kwevelu emisiwe (ngokuvamile ±20mV) uma ishajwe ngokugcwele, ukuze kufinyelelwe ukushajwa okulinganayo kweseli ngalinye kuphakethe lebhethri, okuthuthukisa ngempumelelo umphumela wokushaja ekushajweni kochungechunge. imodi; ngesikhathi esifanayo, ithola i-over-voltage, under-voltage, over-current, short-circuit kanye nezinga lokushisa elingaphezulu kweseli ngalinye kuphakethe lebhethri, ukuvikela nokwelula impilo yebhethri; isivikelo se-under-voltage sivimbela iseli ngalinye ukusuka Iphinde ibone i-over-voltage, i-under-voltage, i-over-current, i-short-circuit kanye nezinga lokushisa elingaphezulu kweseli ngalinye kuphakethe lebhethri ukuze livikele futhi andise impilo yebhethri; ukuvikela okungaphansi kwe-voltage kuvimbela ibhethri ukuthi lonakaliswe ngenxa yokuchitheka ngokweqile lapho iseli ngalinye likhishwa.

Ibhodi lokuvikela iphakethe lebhethri le-lithium-ion lisetshenziselwa ukuvikela ibhethri ukuthi lingashajwa, alishajiwe, alilona elamanje, kukhona nokuvikelwa kwesekethe emfushane okukhiphayo.

Isizathu sokuthi kungani iphekhi yebhethri ye-lithium-ion kufanele ivikelwe sinqunywa izici zayo. Ngenxa yokuthi impahla yebhethri ye-lithium-ion ngokwayo inquma ukuthi ayikwazi ukushajwa ngokweqile, ikhishwe ngokweqile, i-overcurrent, i-short-circuit kanye ne-ultra-high izinga lokushisa lokushaja nokukhipha, ngakho-ke iphakethe lebhethri le-lithium-ion lizohlala lilandelwa ipuleti lokuvikela elithambile futhi kuvela i-fuse yamanje.

Umsebenzi wokuvikela wephakethe lebhethri le-lithium-ion ngokuvamile ufezwa ibhodi lokuvikela kanye nedivayisi yamanje njenge-PTC. Ibhodi lokuvikela lakhiwe isekethe ye-elekthronikhi, engaqapha ngokunembile amandla kagesi weseli yebhethri namandla amanje wesekethe yokushaja nokukhipha ngaso sonke isikhathi ngaphansi kwemvelo engu- -40 ℃ ukuya ku- +85 ℃, futhi ilawule ukukhanya/ukucisha isifunda samanje ngesikhathi; I-PTC ivikela ibhethri emonakalweni omubi ngaphansi kwezinga lokushisa eliphezulu.

Imingcele yezobuchwepheshe yebhodi lokuvikela ibhethri ye-lithium-ion

Isilinganiso samanje: 80mA (uma i-VCELL=4.20V)

Indawo yokuqala yokulinganisa: 4.18±0.03V umkhawulo wokushaja oweqile: 4.25±0.05V

Umkhawulo wokukhipha ngokweqile: 2.90±0.08V

Isikhathi sokulibaziseka kokukhishwa ngokweqile: 5mS

ukukhishwa kokukhipha ngokweqile: nqamula umthwalo futhi i-voltage yeseli ngayinye ingaphezu komkhawulo wokukhipha ngokweqile.

Ukukhishwa kwamanje: nqamula umthwalo ozowukhulula

ukuvikelwa kwezinga lokushisa elingaphezulu: inkinobho yokuvikela izinga lokushisa ebuyiselekayo idinga ukufakwa

Ukusebenza kwamanje: 15A (ngokwezidingo zekhasimende)

Ukusetshenziswa kwamandla okungashintshi: ngaphansi kuka-0.5mA

Umsebenzi wokuvikela isifunda esifushane: ungavikela, unqamule umthwalo ungaba ukuzibuyisela

Imisebenzi ebalulekile: umsebenzi wokuvikela ukushajwa ngokweqile, umsebenzi wokuvikela ukukhishwa, umsebenzi wokuvikela isekethe emfushane, umsebenzi wokuvikela wamanje, umsebenzi wokuvikela izinga lokushisa elingaphezulu, umsebenzi wokuvikela ukulinganisa.

Incazelo yesixhumi esibonakalayo: imbobo yokushaja kanye nembobo yokukhipha ebhodini zizimele komunye nomunye, zombili zihlanganyela isigxobo esiphozithivu, B- isigxobo esinegethivu sebhethri elixhunyiwe, C- isigxobo esinegethivu sembobo yokushaja; I-P- iyisigxobo esingalungile sembobo yokukhipha; B-, P-, C- pads awuhlobo lwe-over-hole, ububanzi bembobo yephedi bungu-3mm; isixhumi esibonakalayo sokutholwa kokushaja ngakunye kwebhethri kukhishwa ngendlela yesibambi sephini ye-DC.

Incazelo yepharamitha: Ukucushwa kwenani lamanje lokuvikelwa okuphezulu kokusebenza kwamanje nokuvikela okweqile ku-A (5/8, 8/15, 10/20, 12/25, 15/30, 20/40, 25/35, 30/50, 35/ 60, 50/80, 80/100), inani elikhethekile le-overcurrent lingenziwa ngokwezifiso ngokuya ngezidingo zekhasimende.

Ingabe amaphakethe ebhethri e-lithium-ion angasetshenziswa ngaphandle kwamapuleti okuvikela?

Kuze kube manje, akukaze kube nesimangalo esidlangalaleni sokungasebenzisi abakhiqizi bebhethri lepuleti lokuvikela.
