Amsa Mai Sauri: Haɗin Wuta da Sadarwar BMS Sun Sha Bamban

Lokacin da fakitin batir da yawa ke aiki a layi ɗaya, haɗa su a gefen wutar lantarki na DC ba ya haɗa na'urorin BMS ɗinsu ta atomatik a gefen sadarwa.

Ga tsarin BMS na ajiyar makamashi na gida na DALY na ƙarni na 4 wanda aka rufe a nan, hanyar sadarwa mai amfani ita ce: Kowace Fakiti → BMS ɗinta → Gano BMS ta atomatik → RS485 na ciki → Babban/Mahadar Sadarwa → Sadarwar Inverter.

Saboda haka abokin ciniki yana buƙatar tabbatar da abubuwa uku daban-daban: kowane fakiti yana da BMS daidai, ana iya gano na'urorin BMS kuma a haɗa su a ciki, kuma tsarin baturi yana amfani da hanyar sadarwa da tsarin da ainihin inverter ke buƙata.

Muhimmin batu:Haɗin lantarki mai layi ɗaya ≠ Sadarwar BMS ≠ Sadarwar inverter.

1. Kowace Fakitin Baturi Har Yanzu Tana da Nasa BMS

A cikin bankin batirin da ke da fakiti da yawa, kowanne fakitin batirin ana sarrafa shi ta hanyar BMS nasa. BMS yana sa ido kuma yana kare wannan fakitin kafin fakitin su shiga cikin babban tsarin adana makamashi.

Wannan yana nufin ya kamata a duba tsarin wutar lantarki da tsarin sadarwa daban-daban. Haɗin DC na gama gari ba ya ƙirƙirar hanyar sadarwa ta BMS da kansa.

2. Tabbatar Ana Iya Gano Kowane BMS

Da zarar na'urorin BMS da yawa sun raba tsarin fakiti ɗaya, tsarin yana buƙatar ingantacciyar hanya don bambanta BMS ɗaya daga wani.

A cikin tsarin DALY 4th Gen mai goyan bayan tsarin layi ɗaya, gano adireshin BMS ta atomatik yana rage buƙatar daidaita adireshin DIP-switch da hannu yayin aiwatarwa.

Duba Abokin Ciniki: Shin tsarin zai iya gano kowane BMS daidai kafin ku ci gaba da sadarwa ta hanyar inverter?

Gano BMS yana warware matakin gano na'urar. Ba shi da tabbacin dacewa da inverter.

3. Haɗa na'urorin BMS ta hanyar Layer ɗin Sadarwa na Ciki

Ga tsarin DALY na ƙarni na 4 wanda kayan samfurin da ake da su suka rufe, sadarwa ta ciki tsakanin na'urorin BMS masu layi ɗaya suna amfani da RS485 a cikin tsarin daisy-chain.

Hanya mai sauƙi ta sadarwa ita ce: Fakiti 1 / BMS 1 → Fakiti 2 / BMS 2 → Fakiti 3 / BMS 3 → … → Fakitin n / BMS n.

Wannan hanyar sadarwa ta RS485 ta bambanta da babban haɗin wutar DC tsakanin fakitin batirin.

Ma'anar ainihin ma'anar fil ɗin mahaɗi, jerin kebul, ƙarewa, da hanyoyin aiwatarwa yakamata su bi takaddun samfurin DALY da suka dace.

4. Raba Sadarwar BMS ta Cikin Gida da Sadarwar Inverter

Tsarin CAN ko RS485 kaɗai ba ya tabbatar da dacewa da inverter. Tsarin inverter na ainihi da kuma tsarin sadarwa da ake buƙata suma dole ne su dace da tsarin BMS da aka zaɓa.

Dokar abokin ciniki: Dacewar hulɗa da kuma dacewa da yarjejeniya bincike ne daban-daban.

5. Jerin Abubuwan da Aka Duba Game da Gudanar da Sadarwa Mai Fakiti Da Yawa

Kammala waɗannan binciken kafin a ɗauki bankin batirin parallel a matsayin tsarin sadarwa na BMS mai haɗaka.

6. Menene DALY 4th Gen Tana Tallafawa Wannan Tsarin Gine-gine?

Don saitunan sa ido masu goyan baya, bayanan fakitin mutum ɗaya na iya haɗawa da lambar fakiti, yanayin aiki, ƙarfin lantarki, halin yanzu, SOC, yanayin caji na MOS, da kuma yanayin MOS da aka fitar.

Wannan labarin ya tsaya ne a kan yanayin sadarwa: wanda aka gano, yadda aka haɗa na'urorin BMS, da kuma yadda tsarin baturi ya isa ga hanyar sadarwa ta inverter.

Tambayar haɗin kai ta gaba: Idan kuna buƙatar tantance wane bayanai na baturi mai fakiti da yawa na inverter ɗin ya karɓa - kamar SOC, halin yanzu, ƙararrawa, ko wasu bayanai na matakin tsarin - tabbatar da halayen bayanan tsarin daban don tsarin BMS da yarjejeniyar inverter da ta dace.

Tambayoyin da ake yawan yi akai-akai

Shin kowace fakitin batirin layi ɗaya tana buƙatar BMS ɗinta?

A cikin tsarin gine-gine masu fakiti da yawa da aka tattauna a nan, eh: kowace fakitin batir ana sarrafa ta ne ta hanyar BMS nata, yayin da tsarin sadarwa ke haɗa na'urorin BMS a matakin tsarin.

Shin DALY 4th Gen yana amfani da RS485 tsakanin fakitin layi ɗaya?

A cikin tsarin DALY 4th Gen da aka tattauna a nan, sadarwa ta ciki mai layi ɗaya-pack BMS tana amfani da RS485. Kada a yi amfani da wannan ga kowane samfurin DALY ko kowane tsarin adana makamashi.

Idan BMS da inverter duka suna da CAN, shin sun dace?

Ba ta atomatik ba. Dole ne a duba yanayin haɗin kai na zahiri, ainihin samfurin inverter, yarjejeniyar sadarwa, da kuma tsarin BMS da aka zaɓa tare.

Nemi Bita na Sadarwa na BMS a Daidaitacce

Don aikin adana makamashi mai fakiti da yawa, aika DALY sinadaran batirinka, ƙidayar S, ƙarfin kowace fakiti, adadin fakitin layi ɗaya, buƙatun halin yanzu na BMS, ainihin samfurin inverter/model, hanyar sadarwa ta CAN/RS485 da ake buƙata, yarjejeniyar sadarwa, buƙatun sa ido, da adadin da ake tsammani.

Wannan yana bawa ƙungiyar fasaha damar tabbatar da tsarin sadarwa kafin a gwada samfurin ko kuma a fara aiki da shi.
