Chiyambi：
Mabatire a lithiamu ali paliponse m'miyoyo yathu. Mabatire athu a foni yam'manja ndi mabatire amagetsi a galimoto ali paliponse.mabatire a lithiamu, koma kodi mukudziwa mawu oyambira a batri, mitundu ya batri, ndi ntchito ndi kusiyana kwa mndandanda wa batri ndi kulumikizana kofanana? Tiyeni tifufuze chidziwitso cha mabatire ndi Heltec.
Mawu oyambira a mabatire a lithiamu
1) C-rate
Amatanthauza chiŵerengero cha mphamvu yamagetsi ndi mphamvu yeniyeni ya batire ya lithiamu panthawi yochaja ndi kutulutsa mphamvu. Amafotokoza momwe batire ingachajidwire ndikutulutsa mphamvu mwachangu. Kuchuluka kwa mphamvu ya chaja ndi kutulutsa mphamvu sikofanana kwenikweni. Mwachitsanzo:
1C: kutulutsa batri yonse mkati mwa ola limodzi (chaji yonse)
0.2C: kutulutsa batri yonse mkati mwa maola 5 (chaja yonse)
5C: kutulutsa batri yonse mkati mwa maola 0.2 (chaja yonse)
2) Kutha
Kuchuluka kwa magetsi omwe amasungidwa mubatri ya lithiamuChipangizocho ndi mAh kapena Ah.
Kuphatikiza ndi liwiro, mwachitsanzo, ngati batire ndi 4800mAh ndipo liwiro lochaja ndi 0.2C, zikutanthauza kuti zimatenga maola 5 kuti batire ikhale yodzaza ndi mphamvu kuchokera pamene ilibe kanthu (kunyalanyaza gawo loti isanachajidwe pamene batire ili yochepa kwambiri).
Mphamvu yochaja ndi: 4800mA*0.2C=0.96A
3) Dongosolo loyang'anira mabatire a BMS
Dongosololi limawongolera ndikuwongolera kuyitanitsa/kutulutsa batri, kuzindikira kutentha ndi mphamvu ya batri, kulumikizana ndi dongosolo lolandirira, kulinganiza mphamvu ya batri, ndikuwongolera magwiridwe antchito achitetezo a paketi ya batri ya lithiamu.
4) Njinga
Njira yochajira ndi kutulutsa batri imatchedwa kuzungulira. Ngati batri imagwiritsa ntchito 80% yokha ya mphamvu zake zonse nthawi iliyonse, nthawi yozungulira ya mabatire a lithiamu-ion ikhoza kukhala yokwera mpaka kasanu ndi kawiri.
Mtundu wa Batri ya Lithium
Pakadali pano, maselo a lithiamu-ion amalonda makamaka ndi ozungulira, ozungulira komanso ofewa.
Maselo ozungulira a 18650 ndi maselo a lithiamu-ion omwe ali ndi kuchuluka kwakukulu kopangidwa pakadali pano. Maselo athu a batri a G series monitor ndi amtunduwu.
Mndandanda wa maselo ndi kulumikizana kofanana
Selo ndiye gawo lalikulu labatri ya lithiamuChiwerengero cha maselo chimasiyana malinga ndi momwe batire imagwiritsidwira ntchito, koma mabatire onse amafunika kulumikizidwa m'njira zosiyanasiyana kuti akwaniritse magetsi ndi mphamvu zomwe zimafunikira.
Dziwani: Mikhalidwe yolumikizirana yofanana ndi yovuta kwambiri. Chifukwa chake, kulumikizana kofanana koyamba kenako kulumikizana kotsatizana kungachepetse kufunikira kwa batri kukhala yogwirizana.
Q: Kodi kusiyana pakati pa mabatire amitundu itatu ndi anayi ndi anayi ndi anayi ndi atatu ndi atatu ndi kotani?
A: Mphamvu yamagetsi ndi mphamvu zimasiyana.Kulumikizana kwa mndandanda kumawonjezera mphamvu yamagetsi, ndipo kulumikizana kofanana kumawonjezera mphamvu yamagetsi (mphamvu)
1) Kulumikizana kofanana
Tangoganizani kuti magetsi a selo ya batri ndi 3.7V ndipo mphamvu yake ndi 2.4Ah. Pambuyo pa kulumikizana kofanana, mphamvu yamagetsi ya dongosololi imakhalabe 3.7V, koma mphamvuyo imawonjezeka kufika pa 7.2Ah.
2) Kulumikizana kwa mndandanda
Tangoganizani kuti magetsi a selo ya batri ndi 3.7V ndipo mphamvu yake ndi 2.4Ah. Pambuyo polumikizana motsatizana, mphamvu yamagetsi ya dongosololi ndi 11.1V, ndipo mphamvuyo siinasinthe.
Ngati batire imodzi ili ndi ma cell atatu ndi awiri ofanana, onse pamodzi ndi ma cell 6 18650, ndiye kuti batireyo ndi 11.1V ndi 4.8Ah. Tesla Model-S sedan imagwiritsa ntchito ma cell a Panasonic 18650, ndipo batire ya 85kWh imafuna ma cell pafupifupi 7,000.
Mapeto
Heltec ipitiliza kusintha chidziwitso chodziwika bwino cha sayansi chokhudzamabatire a lithiamuNgati mukufuna, mutha kuisamalira. Nthawi yomweyo, timakupatsirani mabatire a lithiamu apamwamba kwambiri kuti mugule ndikupereka ntchito zomwe mwasankha kuti zigwirizane ndi zosowa zanu.
Heltec Energy ndi mnzanu wodalirika pakupanga mabatire. Popeza tikuyang'ana kwambiri kafukufuku ndi chitukuko, pamodzi ndi zida zathu zambiri za batire, timapereka mayankho amodzi kuti tikwaniritse zosowa zomwe zikusintha zamakampani. Kudzipereka kwathu ku ntchito yabwino kwambiri, mayankho okonzedwa bwino, komanso mgwirizano wamphamvu ndi makasitomala zimatipangitsa kukhala chisankho chabwino kwambiri kwa opanga mabatire ndi ogulitsa padziko lonse lapansi.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, chonde musazengereze kutifunsatitumizireni uthenga.
