Dab tsi yuav tsum tau txiav txim siab thaum txhim kho lub Lithium roj teeb?

Txhim kho lub roj teeb lithium roj teeb tsis yooj yim li qee tus neeg yuav xav, nws yog ib qho kev ua haujlwm loj thiab yuav tsum ua kom tiav kom zoo thiaj li ua kom koj cov peev nyiaj tau los thiab, qhov tseem ceeb tshaj, ua kom muaj kev nyab xeeb. Hauv cov ntawv tshaj tawm no, peb yuav muab qee cov ntaub ntawv yooj yim los pab koj nkag siab yuav ua li cas kom tsis txhob ua yuam kev kim thaum txhim kho koj lub roj teeb lub zog.

 

 

Rau xam koj cov kev siv zog thiab xav tau System Peev xwm

Koj Kev Siv Txhua Hnub / Xav Tau Lub Zog yog:

Pro Lub Tswv Yim: Xav txog qhov tsawg kawg ib qho ntxiv 20% rau koj qhov peev xwm khaws cia rau hnub npog huab cua thiab kev nthuav dav.

Voltage Compatibility

Feem ntau cov kev teeb tsa hauv tsev ua haujlwm ntawm 48 V system thiab yog qhov txiaj ntsig zoo tshaj plaws rau tus nqi. Txhua Hnub Ci Systems yuav tsum muaj cov inverters uas phim cov zis voltage ntawm cov roj teeb.

Roj teeb Chemistry

Yog li, LiFePO4 roj teeb? Saib lawv tsuas yog xaiv txoj cai xwb. Cov khoom no muaj kev nyab xeeb rau kev siv thiab kav ntev li ntawm 2,000 txog 5,000 tus nqi. Tsis tas li ntawd, lawv ua haujlwm zoo txawm tias nws txias heev lossis kub heev.

Puas yog NMC roj teeb? Lawv ntim cov punch, tab sis koj tus account hauv txhab nyiaj yuav hnov ​​​​nws. Tsis tas li ntawd, lawv tsis yog kiv cua ntawm huab cua huab cua lossis raug khob ib ncig.

Lub cev Dimensions

Nco ntsoov xyuas seb qhov chaw koj lub roj teeb xav tau ntau npaum li cas. Zoo li, 10 kWh LiFePO4 system feem ntau noj li ntawm 400 square feet.

 

 

Cable Size​

Siv cov cables tuab dua rau siab -cov tshuab tam sim no (xws li 2/0 AWG rau 48V / 300Ah).

Txoj cai ntawm Thumb: Khaws qhov hluav taws xob poob<2% (use the formula: VD = (2 × L × I × R) / 1000).

Fusing & Kev Nyab Xeeb​

Nruab Chav T fuses (20,000 AIC qhov ntsuas) ntawm lub davhlau ya nyob twg zoo.

Dab neeg tiag tiag: Ib tug phooj ywg hla fuses thiab kib nws lub inverter thaum lub hnub ci cua daj cua dub -tsis txhob yog nws!

Bus Bars & Terminals​

Siv tooj liab cov tsheb npav rau kev khiav tam sim no.

Torque terminals rau specs (piv txwv li, 15-20 Nm) kom tsis txhob arcing.

 

 

Charger Compatibility​

Siv MPPT hnub ci chargers (20-30% ntau npaum li PWM).

Rau kab hluav taws xob- khi tshuab, xyuas inverter compatibility nrog LiFePO4 .

Charging Parameters​

Tus nqi them0.5C-1C (piv txwv li, 50A rau 100Ah roj teeb).

Kev them nyiaj kub kub: Txo them tam sim no los ntawm 0.05V /℃saum 25 degree.

 

 

Kev Tshawb Fawb Txhua hli​

Tshawb xyuas cov terminals rau corrosion (ntshiab nrog baking soda + dej).

Saib xyuas SoC ntawm BMS app (kwv nws ntawm 20–80% rau kev siv txhua hnub).

Txhua xyoo Deep Dive​

Sib npaug (0.1V tshaj li qub) kom sib npaug ntawm cov hlwb.

Kuaj BMS firmware hloov tshiab (cov kab mob tshwm sim!).

Case Study: The Off-Grid Cabin Win​

Ntsib Sarah, tus tswv tsev nyob deb nroog Alaskan:

Teeb tsa: 20 kWh LiFePO4 + 10 kW hnub ci + Tesla Powerwall.

Feem ntau yuam kev kom zam​

Mixing Old & New Battery: Guarantees imbalance thiab thaum ntxov tsis ua hauj lwm.

Tsis quav ntsej qhov cua: Kub tua-ib txwm ntxiv cov kiv cua yog tias qhov kub siab tshaj 35℃.

Pheej yig Cables: Txuag 100 tam sim no, them 5,000 tom qab kev puas tsuaj hluav taws.

Daim Ntawv Xeem Kawg​

✅ Txheeb xyuas qhov yuav tsum tau muaj kev pov hwm (qee qhov yuav tsum tau muaj ntawv pov thawj installers).

✅ Kuaj BMS kev sib txuas lus nrog inverters / chargers.

✅ Khaws ib daim ntawv teev cov hluav taws xob, qhov kub thiab txias.

Vim li cas thiaj tso siab rau peb?​

Peb tau muab tso rau hauv ntau tshaj 500 lub tshuab, yog li peb paub yuav ua li cas messed khoom tuaj yeem tau txais yog tias koj hla cov kauj ruam. Ua raws li cov lus qhia no, thiab koj yuav cawm koj tus kheej ntau yam teeb meem thiab tau txais txiaj ntsig ntau ntawm koj lub roj teeb.
