Ibhethri le-LiFePO4 elingenayo i-BMS liyisibopho esingavikelwe.
Isenzakalo esisodwa sokushaja ngokweqile singabhubhisa amaseli unomphela. I-BMS engalungile
kubangela izinyanga zokunqamuka okungaqondakali kanye nokusetshenziswa kwamandla okuchitha isikhathi. Lo mhlahlandlela
ihlanganisa konke okudingayo ukuze wenze isinqumo esifanele.
I-BMS yenza imisebenzi emithathu ngesikhathi esisodwa:
Isivikeloinquma isekethe ngesikhathi noma yiliphi iseli lidlula ifasitela lalo eliphephile — ukushaja okungaphezu kuka-3.65 V/iseli, ukukhishwa okungaphansi kuka-2.8 V/iseli (umkhawulo wokusebenza onconywayo), noma lapho izimo zamanje, izinga lokushisa, noma zesekethe esifushane ziba yingozi.
Ukulinganiselailungisa ukuzulazula kwemvelo phakathi kwamaseli ngamanye emijikelezweni engamakhulu. Ngaphandle kwayo, iseli lakho elibuthakathaka kakhulu lichaza amandla angasetshenziswa yiphakethe lakho lonke - futhi liwohloka ngokushesha.
UkuqaphaIlandelela isimo sokushaja (i-SOC), isimo sempilo (i-SOH), i-voltage ngeseli ngalinye, izinga lokushisa, kanye nokubalwa komjikelezo ngesikhathi sangempela. Le datha ikuvumela ukuthi ubambe iseli elihlulekayo ngaphambi kokuba lidilize iphakethe.
Ijika lokukhipha eliyisicaba le-LiFePO4 lidinga i-BMS eqondene ne-chemistry. I-BMS ejwayelekile izofunda kabi i-SOC kulo lonke ithafa futhi ibangele ukunqamuka kwamandla kagesi aphansi okungamanga okusele amandla amakhulu.
Indlela Yokulinganisa I-BMS Yakho
Imininingwane emibili kumele ifane kahle nephakethe lakho.
Isinyathelo 1 — I-Voltage (inani lamaseli ochungechunge).Iphakethe le-4S lidinga i-4S BMS. Iphakethe le-16S lidinga i-16S BMS. Ukuvalwa kweseli elilodwa kubangela ukungafundi kahle kwamandla kagesi kanye nokuvikelwa okungathembekile.
| Ukulungiselela | I-Voltage Ejwayelekile | I-Voltage Ephezulu Yokushaja | Isicelo Esijwayelekile |
|---|---|---|---|
| 4S | 12.8 V | 14.6 V | I-RV, i-marine, ngaphandle kwegridi |
| 8S | 25.6 V | 29.2 V | Ama-trolling motors, amandla elanga angu-24V |
| 16S | 51.2 V | 58.4 V | Indawo yokugcina izinto ekhaya, inqola yegalofu |
| 24S | 76.8 V | 87.6 V | I-72V EV, yezimboni |
Isinyathelo 2 - Okwamanje.Hlukanisa umthwalo wakho oqhubekayo ophezulu ngama-watts nge-voltage yephakethe, bese wengeza i-margin yokuphepha engu-25–30%.
5,000 W ÷ 48 V = 104 A → Khetha i-BMS engu-150 AUngalokothi usebenzise i-BMS ngo-100% wamandla ayo alinganiselwe. Ukunciphisa ukushisa kanye nemithwalo yokwanda kwamandla kuhlale kusunduza isidingo sangempela ngaphezu kwesibalo esibaliwe.
Ukulinganisela Okusebenzayo vs. Okungasebenzi
Ukulinganisela okungenamsebenziIchitha ishaja eningi njengokushisa nge-resistor (50–200 mA). Igcina amaphakethe ahambisana kahle kodwa ayikwazi ukubuyisa ukugeleza okukhulu kweseli — ukulungisa ukungalingani kwe-500 mAh kuthatha cishe amahora ama-5 ku-100 mA.
Ukulinganisela okusebenzayoIdlulisela amandla phakathi kwamaseli ngesekethe ye-inductor-capacitor (1–5 A, ukusebenza kahle okungu-80–95%). Ilungisa ukungalingani ngokushesha okungu-10–50× futhi isebenza kulo lonke umjikelezo wokushaja okugcwele nokukhipha, hhayi nje phezulu.
| Isimo | Ukungenzi lutho | Kuyasebenza |
|---|---|---|
| Amaseli eqembu elifanayo, ≤ 0.3C ukujikeleza | Kwanele | Intuthuko engaphansi |
| Iphakethe ≥ 200 Ah, ukugibela ibhayisikili nsuku zonke | Imizabalazo | Kunconyiwe |
| Izinga lokukhipha igesi > 0.5C eliqhubekayo | Ayikwazi ukulandelela | Kuyadingeka |
| Amaseli ahlanganisiwe noma asebekhulile | Ayikwazi ukululama | Ingabuyisa iphakethe |
Khetha ukungasebenzikumaseli eqembu elifanayo ajikelezwe ku-≤ 0.3C.
Khetha okusebenzayokumaphakethe angu-≥ 200 Ah, amazinga okukhishwa angaphezu kuka-0.5C, noma amaseli avela kumaqoqo axubile.
Uhlu Lokuhlola Lokukhetha Okuguquguqukayo Okune
Ngaphambi koku-oda, qinisekisa zonke iziguquguquko ezine ngasikhathi sinye:
| Okuguquguqukayo | Isidingo |
|---|---|
| Inani lochungechunge | Ifana ncamashi nokucushwa kweseli lakho |
| I-current eqhubekayo | Umthwalo ophezulu (W) ÷ i-voltage (V) + imajini engu-25–30% |
| Izici | I-Bluetooth (konke) · I-RS485/I-CAN (yelanga) · Ukulinganisela okusebenzayo (≥ 200 Ah) |
| Ikhemistri | Qinisekisa ukucushwa komkhawulo we-LFP/LiFePO4 |
Amayunithi e-DALY Energy BMS amboza ama-4S kuya ku-24S kanye nama-10 A kuya ku-500 A, kuzilungiselelo ezijwayelekile, ezihlakaniphile (i-Bluetooth + RS485/CAN), kanye nebhalansi esebenzayo — konke kuthunyelwa ngemikhawulo ye-LFP chemistry ngokuzenzakalelayo.
