Menene matsakaicin adadin fitarwa na 3.2V 302Ah LiFePO4 sel prismatic

Matsakaicin ci gaba Yawan fitarwa don na yau da kullun 3.2V 302Ah LiFePO4 prismatic cell ne 1C, wanda yayi daidai 302 Amsoshi.

Duk da haka, wannan shine mafarin farawa. Bari mu karya cikakkun bayanai, gami da kololuwa (fashe) rates da mahimman abubuwan da ke tasiri wannan lambar.

1. Ƙididdigar Ƙididdiga: Cigaba da Cigaba (1C)

• 1C darajar: Don cell 302Ah, adadin fitarwa na 1C yana nufin zane 302 amps ci gaba. Wannan zai, a ka'idar, rage baturin daga 100% ku 0% a cikin sa'a daya (karkashin ingantattun yanayi).

• Matsayin Masana'antu: Mafi mashahuri masana'antun LiFePO4 prismatic sel (kamar EVE, CATL, REPT) kimanta daidaitattun sel ɗin su don a matsakaicin ci gaba da fitarwa na yanzu na 1C. Ana ɗaukar wannan a matsayin amintaccen kuɗi mai dorewa wanda ke haɓaka rayuwar sake zagayowar.

2. Matsakaicin Fitar da Kololuwa ko Bugawa

Yawancin sel suna iya ɗaukar igiyoyi masu tsayi na ɗan gajeren lokaci, wanda aka sani da bugun bugun jini ko mafi girma.

• Ƙididdigar gama gari: Mahimman ƙimar fitarwar bugun jini shine 2C ko 3C domin durations na 2-5 seconds.

• Domin 302Ah Cell: Wannan yana nufin a kololuwar halin yanzu na 604 Amsoshi (ku 2c) ko ma 906 Amsoshi (ku 3c).

• Muhimmiyar Magana: Fitar da bugun jini yana haifar da zafi mai mahimmanci. Yawan bugun jini ko bugun jini fiye da ƴan daƙiƙa kaɗan na iya haifar da zafin jiki ya tashi da sauri, yuwuwar haifar da Tsarin Gudanar da Baturi mai karewa (BMS) don rufewa ko haifar da lalacewa na dogon lokaci.

3. Mahimman Factor: Takardar bayanan Doka ce

Wannan shine mafi mahimmancin sashin amsa. Da “1C ci gaba, 2C/3C bugun jini” babban ka'ida ce ga sel da yawa, amma dole ne ku bincika takamaiman takaddar bayanan da mai yin sel ɗinku ya bayar.

Masana'antun daban-daban har ma da nau'ikan tantanin halitta daban-daban a cikin tambari na iya samun fayyace mabanbanta. Misali:

• “Makamashi” Kwayoyin halitta: An tsara don iya aiki (kamar don ajiyar rana), Ana ƙididdige waɗannan sau da yawa a 0.5C ko 1C ci gaba da fitarwa. Suna ba da fifiko ga tsawon rai da ƙarfin kuzari akan babban iko.

• “Ƙarfi” Kwayoyin halitta: An tsara don aikace-aikacen fitarwa mai girma (kamar na sarrafa injina a cikin EVs ko kwale-kwale), ana iya kimanta su don 3C, 5C, ko ma mafi girma ci gaba da fitarwa. Waɗannan sel galibi suna musayar ƙaramin adadin iya aiki don ƙaramin juriya na ciki.

Dole ne ku nemo takardar bayanan don ainihin ƙirar ku don sanin madaidaicin iyakar ci gaba da ƙimar fitarwar bugun jini.

4. Iyakokin Duniya na Gaskiya: Ba kawai Tantanin halitta ba

Ko da an ƙididdige tantanin halitta don 1C (302A), tsarin ku ainihin Matsakaicin adadin fitarwa za a iyakance shi ta wasu abubuwan haɗin gwiwa:

1. Tsarin kula da batir (BMS): Wannan shi ne mafi na kowa iyakance. BMS yana kare baturin. Dole ne ku yi amfani da ƙimar BMS don ɗaukar nauyin matsakaicin ci gaba na halin yanzu ka shirya zana. Farashin 302A, kuna buƙatar BMS da aka ƙididdige shi aƙalla 300A (zai fi dacewa 350A ko mafi girma don samun tazarar aminci).

2. Wiring da Connectors: Duk igiyoyi, lugga, kuma dole ne a yi girman masu haɗin haɗin kai daidai da na yanzu don hana faɗuwar wutar lantarki, asarar wutar lantarki, da kuma zafi mai haɗari. Domin 300+ amps, wannan yana buƙatar kebul mai kauri sosai (E.g., 4/0 ko 00 AWG).

3. Zazzabi: Yin caji a 1C zai haifar da zafi. Ayyukan baturi da tsawon rayuwa sun fi kyau a cikin takamaiman kewayon zafin jiki (yawanci 15 ° C – 35°C). Fitar da ruwa mai yawa a cikin yanayi mai zafi na iya haifar da BMS don murƙushe fitar da ruwa na yanzu don kare sel..

Taƙaitawa & Misali

• Tsarin Mulki: 302 Amps ci gaba (1C Kasa).

• Koli mai yiwuwa: ~ 600-900 Amps na 'yan dakiku (2C-3C bugun jini), amma duba daftarin aiki.

• Halin Mulki: Takardar bayanan masana'anta don takamaiman samfurin cell ɗin ku.

• Iyakar tsarin: BMS ku da wayoyi dole ne a kimanta don sarrafa halin yanzu da kuke son zana.

Misali Lissafi:
Idan kana da bankin baturi 48V da aka yi daga 16 daga cikin sel 302Ah (16 * 3.2V = 51.2V mai ƙima), kuma kuna fitarwa akan ƙimar 1C (302A):

• Ƙarfi (Watts) = Voltage (V) × Yanzu (A)

• Ƙarfin wutar lantarki = 51.2V × 302A = ~ 15,462 Watts
  Don haka, za ku iya gudu a bisa ka'ida 15.5 kW kaya ci gaba daga wannan baturi.
