Yankho Lalifupi: Kulumikizana kwa Mphamvu ndi Kulankhulana kwa BMS Ndi Kosiyana

Pamene mabatire angapo akugwira ntchito limodzi, kuwalumikiza kumbali yamagetsi ya DC sikulumikiza okha mayunitsi awo a BMS kumbali yolumikizirana.

Pa kapangidwe ka BMS ka DALY 4th Gen Home Energy Storage komwe kafotokozedwa pano, njira yolumikizirana yothandiza ndi iyi: Phukusi Lililonse → BMS Yake → Kuzindikiritsa BMS Yokha → RS485 Yamkati → Malo Olumikizirana Akuluakulu/Okhala Nawo → Kulumikizana kwa Inverter.

Chifukwa chake kasitomala ayenera kutsimikizira zinthu zitatu padera: paketi iliyonse ili ndi BMS yolondola, mayunitsi a BMS amatha kuzindikirika ndikulumikizidwa mkati, ndipo makina a batri amagwiritsa ntchito mawonekedwe ndi protocol yomwe inverter yeniyeni imafuna.

Mfundo yaikulu:Kulumikizana kwamagetsi kofanana ≠ Kulumikizana kwa BMS ≠ Kulumikizana kwa inverter.

1. Batire iliyonse ili ndi BMS yakeyake

Mu batire yokhala ndi mabatire ambiri, batire iliyonse imayang'aniridwa ndi BMS yakeyake. BMS imayang'anira ndikuteteza paketi iliyonseyo isanayambe kugwira ntchito mu dongosolo lalikulu losungira mphamvu.

Izi zikutanthauza kuti kapangidwe ka mphamvu ndi kapangidwe ka kulumikizana ziyenera kufufuzidwa padera. Kulumikizana kofala kwa DC sikupanga netiweki yolumikizirana ya BMS yokha.

2. Onetsetsani kuti BMS Iliyonse Ikhoza Kudziwika

Magawo angapo a BMS akagawana dongosolo limodzi la mapaketi ambiri, dongosololi limafunika njira yodalirika yosiyanitsira BMS imodzi ndi inzake.

Mu kapangidwe ka DALY 4th Gen parallel, kuzindikira adilesi ya BMS yokha kumachepetsa kufunikira kwa kukonza adilesi ya DIP-switch pamanja panthawi yoyambitsa.

Kufufuza kwa kasitomala: Kodi makina amatha kuzindikira BMS iliyonse molondola musanapitirize kulumikizana ndi inverter?

Kuzindikira BMS kumathetsa vuto la kuzindikira chipangizo. Sikutsimikizira kuti chipangizocho chikugwirizana ndi inverter.

3. Lumikizani mayunitsi a BMS kudzera mu gawo la kulumikizana kwamkati

Pa kapangidwe ka DALY 4th Gen komwe kali ndi zinthu zomwe zilipo, kulumikizana kwamkati pakati pa mayunitsi a BMS omwe ali ndi pack imodzi kumagwiritsa ntchito RS485 mu dongosolo la daisy-chain.

Njira yosavuta yolankhulirana ndi iyi: Phukusi 1 / BMS 1 → Phukusi 2 / BMS 2 → Phukusi 3 / BMS 3 → … → Phukusi n / BMS n.

Njira yolumikizirana iyi ya RS485 ndi yosiyana ndi kulumikizana kwakukulu kwa mphamvu ya DC pakati pa mabatire.

Matanthauzidwe enieni a pini yolumikizira, ndondomeko ya chingwe, kutha, ndi njira zoyankhira ziyenera kutsatira zolemba zoyenera za DALY.

4. Kusiyanitsa Kulankhulana kwa BMS Yamkati ndi Kulankhulana kwa Inverter

Chida cholumikizira cha CAN kapena RS485 chokha sichimakhazikitsa kugwirizana kwa inverter. Mtundu weniweni wa inverter ndi njira yolumikizirana yofunikira iyeneranso kufanana ndi kasinthidwe ka BMS kosankhidwa.

Lamulo la kasitomala: Kugwirizana kwa mawonekedwe ndi kuyanjana kwa protocol ndi macheke osiyana.

5. Mndandanda Woyang'anira Kutumiza Mauthenga Amitundu Iwiri

Malizitsani kufufuza kumeneku musanagwiritse ntchito banki ya batri yofanana ngati njira yolumikizirana ya BMS.

6. Kodi DALY 4th Gen Imathandizira Chiyani pa Kapangidwe Kameneka?

Pazowunikira zomwe zimathandizidwa, zambiri za phukusi lililonse zitha kuphatikizapo nambala ya phukusi, momwe ntchito ikuyendera, mphamvu yamagetsi, mphamvu yamagetsi, SOC, momwe ntchito ya MOS imayendera, ndi momwe ntchito ya MOS imayendera.

Nkhaniyi ikutha pa topology yolumikizirana: ndani amene amadziwika, momwe mayunitsi a BMS amalumikizirana, ndi momwe dongosolo la batri limafikira pa inverter interface.

Funso lotsatira lokhudzana ndi kuphatikiza: Ngati mukufuna kudziwa deta ya batri ya mapaketi ambiri yomwe inverter imalandira—monga SOC, current, alamu, kapena zina zomwe zili mu dongosolo—tsimikizirani momwe deta ya dongosolo imagwirira ntchito padera pa kasinthidwe ka BMS ndi protocol ya inverter.

FAQ

Kodi batire iliyonse yofanana ikufunika BMS yakeyake?

Mu kapangidwe ka ma pack ambiri komwe kakambidwa pano, inde: batire iliyonse imayang'aniridwa ndi BMS yakeyake, pomwe kapangidwe ka kulumikizana kamalumikiza mayunitsi a BMS pamlingo wamakina.

Kodi DALY 4th Generation imagwiritsa ntchito RS485 pakati pa ma pack ofanana?

Mu kapangidwe ka DALY 4th Gen komwe kwatchulidwa pano, kulumikizana kwa BMS kwamkati komwe kumayenderana kumagwiritsa ntchito RS485. Musamafotokoze izi ku chinthu chilichonse cha DALY kapena kapangidwe kalikonse kosungira mphamvu.

Ngati BMS ndi inverter zonse zili ndi CAN, kodi zimagwirizana?

Osati zokha. Mawonekedwe enieni, mtundu weniweni wa inverter, njira yolumikizirana, ndi kasinthidwe ka BMS kosankhidwa ziyenera kufufuzidwa pamodzi.

Pemphani Ndemanga ya Parallel BMS Communication

Pa ntchito yosungira mphamvu ya mapaketi ambiri, tumizani DALY batire yanu, kuchuluka kwa S, mphamvu pa paketi iliyonse, chiwerengero cha mapaketi ofanana, BMS current requirement, mtundu/mtundu weniweni wa inverter, mawonekedwe ofunikira a CAN/RS485, njira yolumikizirana, kufunikira kowunikira, ndi kuchuluka komwe kumayembekezeredwa.

Izi zimathandiza gulu la akatswiri kutsimikizira kapangidwe ka kulumikizana asanayesere zitsanzo kapena kuyambitsa ntchito.
