Lub roj teeb LiFePO4 uas tsis muaj BMS yog lub luag haujlwm tsis muaj kev tiv thaiv.
Ib qho kev them nqi ntau dhau tuaj yeem ua rau cov hlwb puas tsuaj mus tas li. BMS tsis raug
ua rau muaj ntau lub hlis ntawm kev txiav tawm phantom thiab lub peev xwm pov tseg. Phau ntawv qhia no
npog txhua yam koj xav tau los txiav txim siab zoo.
Ib lub BMS ua peb txoj haujlwm tib lub sijhawm:
Kev Tiv Thaivtxiav lub voj voog thaum twg muaj lub cell twg dhau nws lub sijhawm nyab xeeb - them siab tshaj 3.65 V/cell, tso tawm qis dua 2.8 V/cell (qhov txwv ua haujlwm pom zoo), lossis thaum tam sim no, kub, lossis luv luv Circuit ua rau muaj kev phom sij.
Kev sib npaugkho qhov kev hloov pauv ntuj tsim ntawm cov hlwb ib leeg dhau ntau pua lub voj voog. Yog tsis muaj nws, koj lub hlwb tsis muaj zog tshaj plaws txhais tau tias tag nrho koj lub pob muaj peev xwm siv tau - thiab lwj sai tshaj plaws.
Kev saib xyuastaug qab lub xeev them (SOC), lub xeev kev noj qab haus huv (SOH), qhov hluav taws xob ib lub cell, qhov kub, thiab suav lub voj voog hauv lub sijhawm tiag tiag. Cov ntaub ntawv no cia koj ntes tau lub cell ua haujlwm tsis zoo ua ntej nws rhuav tshem lub pob.
LiFePO4 txoj kab tso tawm tiaj tiaj tshwj xeeb xav tau BMS tshwj xeeb rau tshuaj lom neeg. BMS dav dav yuav nyeem SOC tsis raug thoob plaws hauv thaj chaw tiaj tus thiab ua rau muaj kev txiav tawm hluav taws xob qis cuav nrog lub peev xwm tseem ceeb.
Yuav Ua Li Cas Loj Koj Lub BMS
Ob qho specs yuav tsum phim koj lub pob khoom raws nraim.
Kauj Ruam 1 — Qhov hluav taws xob (sib suav cov cell series).Ib pob 4S xav tau 4S BMS. Ib pob 16S xav tau 16S BMS. Ib lub cell tawm ua rau tsis nyeem tau qhov voltage thiab tiv thaiv tsis tau zoo.
| Teeb tsa | Lub zog nominal | Qhov Siab Tshaj Plaws ntawm Kev Them Nqi | Daim Ntawv Thov Ib Txwm Muaj |
|---|---|---|---|
| 4S | 12.8 V | 14.6 V | RV, marine, tawm ntawm grid |
| 8S | 25.6 V | 29.2 V | Cov cav trolling, 24V hnub ci |
| 16S | 51.2 V | 58.4 V | Chaw cia khoom hauv tsev, lub tsheb golf |
| 24S | 76.8 V | 87.6 V | 72V EV, kev lag luam |
Kauj Ruam 2 — Tam sim no.Faib koj qhov siab tshaj plaws ntawm qhov txuas ntxiv mus rau hauv watts los ntawm lub zog hluav taws xob ntawm pob khoom, tom qab ntawd ntxiv 25–30% kev nyab xeeb.
5,000 W ÷ 48 V = 104 A → Xaiv 150 A BMSTsis txhob khiav BMS ntawm 100% ntawm nws cov hluav taws xob tam sim no. Kev txo qhov kub thiab cov khoom siv hluav taws xob ntau dhau ib txwm thawb qhov kev thov tiag tiag ntau dua li tus lej xam.
Kev Sib Npaug Ua Haujlwm vs. Kev Sib Npaug Tsis Zoo
Kev sib npaug tsis tu ncuankim cov nqi ntau dhau ua cua sov los ntawm lub resistor (50–200 mA). Nws ua kom cov pob khoom sib phim zoo tab sis tsis tuaj yeem rov qab tau qhov teeb meem loj ntawm lub cell - kev kho qhov tsis sib npaug ntawm 500 mAh siv sijhawm li 5 teev ntawm 100 mA.
Kev sib npaug nquagHloov lub zog ntawm cov cell ntawm lub voj voog inductor-capacitor (1–5 A, 80–95% efficiency). Nws kho qhov tsis sib npaug sai dua 10–50 × thiab ua haujlwm thoob plaws lub voj voog them thiab tso tawm tag nrho, tsis yog nyob rau sab saum toj xwb.
| Xwm txheej | Tsis ua haujlwm | Ua haujlwm |
|---|---|---|
| Cov hlwb tib yam, ≤ 0.3C kev caij tsheb kauj vab | Txaus | Kev txhim kho me ntsis |
| Pob ≥ 200 Ah, caij tsheb kauj vab tob txhua hnub | Kev Tawm Tsam | Pom zoo |
| Tus nqi tawm > 0.5C tas mus li | Tsis tuaj yeem taug qab | Yuav tsum muaj |
| Cov hlwb sib xyaw ua ke lossis cov hlwb laus | Tsis tuaj yeem rov qab tau | Rov qab tau pob khoom |
Xaiv qhov tsis siv neegrau tib lub hlwb uas tau hloov pauv ntawm ≤ 0.3C.
Xaiv cov khoom siv nquagrau cov pob khoom ≥ 200 Ah, cov nqi tso tawm siab dua 0.5C, lossis cov hlwb los ntawm cov pawg sib xyaw.
Daim Ntawv Teev Xaiv Plaub Qhov Hloov Pauv
Ua ntej yuav xaj, xyuas kom meej tag nrho plaub qhov hloov pauv tib lub sijhawm:
| Hloov pauv tau | Qhov Yuav Tsum Tau Ua |
|---|---|
| suav cov koob | Sib phim koj qhov kev teeb tsa ntawm lub xov tooj ntawm tes |
| Tam sim no tas mus li | Qhov siab tshaj plaws (W) ÷ qhov hluav taws xob (V) + 25–30% ntawm qhov ntsuas |
| Cov yam ntxwv | Bluetooth (txhua yam) · RS485/CAN (hnub ci) · Kev sib npaug zog (≥ 200 Ah) |
| Tshuaj lom neeg | Paub meej tias qhov kev teeb tsa ntawm LFP/LiFePO4 |
Cov chav DALY Energy BMS npog 4S txog 24S thiab 10 A txog 500 A, hauv tus qauv, ntse (Bluetooth + RS485/CAN), thiab kev teeb tsa sib npaug nquag - txhua tus xa nrog LFP chemistry thresholds los ntawm lub neej ntawd.
