Kusankha BMS ya makina osungira mphamvu a LiFePO4 sikophweka monga kufananiza mphamvu ya inverter ndi 100A, 150A, kapena 200A BMS.
Mphamvu yamagetsi ya BMS yolondola imadalira mphamvu yamagetsi yomwe inverter imafuna—osati mphamvu yamagetsi yokha. Njira yosankha yothandiza ndi iyi:
Yankho Lalifupi: Musasankhe BMS Current Kuchokera ku Inverter Watts Yokha
Yambani ndi datasheet yeniyeni ya inverter. Chongani magawo asanu awa:
- Mphamvu yogwira ntchito yopitilira (W)
- Ma voltage ogwiritsira ntchito batri/DC (V)
- Mphamvu yayikulu yotulutsa batri (A)
- Mphamvu yayikulu ya batri (A)
- Mphamvu ya pachimake/kukwera ndi nthawi yake
Mphamvu ya batri ≈ Mphamvu yonyamula ya AC ÷ (Voteji ya batri × Kugwiritsa ntchito bwino kwa Inverter)
Mwachitsanzo, 5,000W ÷ 51.2V ≈ 97.7A. Koma 97.7A ndi kuwerengera kwa mphamvu yamagetsi koyenera—si umboni wakuti 100A BMS ndiyoyenera.

1Choyamba Chongani Inverter Datasheet
Tsegulani deta ya chitsanzo chenicheni cha inverter ndikupeza mfundo zomwe zili pansipa.
| Chizindikiro | Zimene Mukufunikira |
|---|---|
| Mphamvu yogwira ntchito yopitilira | Kuchuluka kwa W kosalekeza |
| Mphamvu yamagetsi ya batri/DC | Mitundu yogwiritsira ntchito yogwira ntchito |
| Kutulutsa kwa batri kwakukulu | A, ngati yatchulidwa |
| Mphamvu yayikulu ya batri | A |
| Mphamvu yokwera/kukwera | W kapena mlingo woyenera wa wopanga |
| Kutalika kwa nthawi yowonjezereka | Masekondi/mphindi, monga momwe zafotokozedwera |
Ngati mphamvu yotulutsira batire yayikulu yatchulidwa kale pa momwe imagwirira ntchito, gwiritsani ntchito mtengo umenewo ngati njira yoyamba yopangira. Apo ayi, pitirizani ndi kuyerekezera mphamvu ya batire ndi mbali yake.
2Yerekezerani Mphamvu ya Batri
Ngati deta ya batri yeniyeni sikupezeka, yambani ndiP = V × IChifukwa chake:
Pa batire ya 16S LiFePO4 yokhala ndi voteji yodziwika ya 51.2V yopereka katundu wa 5,000W:
5,000 ÷ 51.2 ≈ 97.7A
Kuti mupeze kuyerekezera koyenera, phatikizani magwiridwe antchito a inverter:
Ngati 95% ya ntchito ikugwiritsidwa ntchito ngati chitsanzo chokha:5,000 ÷ (51.2 × 0.95) ≈ 102.8AMusaganize kuti 95% ya inverter iliyonse ndi yokwanira; gwiritsani ntchito deta yofunikira ya wopanga nthawi iliyonse yomwe ilipo.
3Gwiritsani ntchito Voltage Yoyenera ya Batri
Pa mphamvu yomweyo,Mphamvu yamagetsi yotsika imatanthauza mphamvu yamagetsi ya batri yokwera.
| Mphamvu ya Batri Yowonetsera | Mphamvu yamagetsi pa 5,000W |
|---|---|
| 54V | 92.6A |
| 51.2V | 97.7A |
| 48V | 104.2A |
Ma voltage awa ndi zitsanzo chabe. Pa kapangidwe kake, gwiritsani ntchito voltage yogwiritsira ntchito yochokera ku batri ndi ma inverter. Musamange kukula kwa mphamvu yamagetsi kuchokera ku voltage yodziwika yokha.
4Yang'anani Mphamvu Yopitirira ndi Mphamvu Yopitirira Payokha
BMS iyenera kuyesedwa poganizira zofunikira zogwirira ntchito mosalekeza komanso kufunikira kulikonse kwakanthawi kochepa.
Mphamvu yopitilira
Tsimikizirani mphamvu ya batri yomwe ikufunika pamene inverter ikupereka katundu wokhazikika womwe ukuyembekezeka. Njira yonse yamagetsi—ma cell, mabasi, BMS, zingwe, zolumikizira, zida zotetezera ndi inverter—ziyenera kuthandizira izi.
Kuwonjezeka kwa magetsi
Ma mota, ma compressor, mapampu ndi katundu wofanana nawo angapangitse kuti pakhale kufunikira koyambira kwakanthawi kochepa.
Mphamvu yamagetsi ya peak popanda nthawi ndi chidziwitso chosakwanira.
Yerekezerani mphamvu ya inverter surge + nthawi → nthawi yofunikira ya batri-side surge current + nthawi → BMS yalemba za mphamvu ya nthawi yochepa komanso khalidwe la chitetezo → mphamvu ya selo ndi njira yamagetsi.
5Chongani Ndalama Yogulira Payokha
Mphamvu yamagetsi yochaja ndi mphamvu yotulutsa mphamvu ndi zofunikira zosiyana. Dziwani mphamvu yamagetsi yayikulu yomwe inverter/chaja kapena makina ochaja angapereke ku batri, kenako yerekezani ndi mphamvu yamagetsi ya cell, kapangidwe ka paketi, mphamvu yamagetsi ya BMS komanso momwe imagwirira ntchito.

Mafunso Ofunsidwa Kawirikawiri
Q1Kodi ndikufunika BMS ya kukula kotani pa inverter ya 5kW 48V?
Palibe BMS current rating yodziwika bwino pa inverter iliyonse ya 5kW 48V. Choyamba yang'anani mphamvu yayikulu yotulutsa batri ya inverter, ngati yatchulidwa. Apo ayi, yesani mphamvu ya batri kuchokera ku mphamvu yogwira ntchito yokhazikika, mphamvu ya batri yoyenera komanso momwe inverter imagwirira ntchito, kenako tsimikizirani kuchuluka kwa mphamvu, mphamvu ya chaji, mphamvu ya selo ndi zidziwitso za BMS.
Q2Kodi 100A BMS yokwanira kugwiritsa ntchito inverter ya 5kW?
Sizingatsimikizidwe kuchokera ku 5kW yokha. Mwachitsanzo, 5,000W yogawidwa ndi 51.2V ndi pafupifupi 97.7A musanaganizire za kutayika kwa inverter. Mphamvu ya batri imatha kupitirira 100A mukangogwira ntchito bwino komanso magetsi oyenera ogwirira ntchito aphatikizidwa.
Q3Kodi batri Ah imazindikira mphamvu ya BMS?
Ayi. Kuchuluka kwa batri mu Ah ndi BMS current mu A kumafotokoza magawo osiyanasiyana. Pa inverter system, dziwani mphamvu ya batri yofunikira kuchokera ku mphamvu ya system ndi momwe imagwirira ntchito, kenako tsimikizirani kuti ma cell ndi BMS akhoza kuithandiza.
Q4Kodi mphamvu ya inverter surge imakhudza kusankha kwa BMS?
Inde, ngati makina a batri akuyembekezeka kupereka kuchuluka kwa kukwera kumeneko. Yang'anani kukula kwa kukwera ndi nthawi yake, kenako yerekezerani kufunikira kwa batri komwe kwachitika ndi mphamvu yolembedwa ya BMS yofupikitsa, momwe chitetezo chimakhalira, maselo ndi njira yamagetsi.
Pemphani Kusankha BMS
