Koj puas tau pom tias lub roj teeb lithium qhov hluav taws xob poob qis tom qab nws them tag nrho? Qhov no tsis yog qhov tsis xws luag - nws yog ib qho kev coj cwj pwm ntawm lub cev hu uahluav taws xob poob. Cia peb coj peb 8-cell LiFePO₄ (lithium hlau phosphate) 24V tsheb roj teeb demo qauv ua piv txwv los piav qhia.
1. Voltage poob yog dab tsi?
Txoj kev xav, lub roj teeb no yuav tsum ncav cuag 29.2V thaum them tag nrho (3.65V × 8). Txawm li cas los xij, tom qab tshem tawm qhov hluav taws xob sab nraud, qhov hluav taws xob sai sai poob mus rau ib puag ncig 27.2V (txog 3.4V ib lub xov tooj). Nov yog vim li cas:
- Qhov siab tshaj plaws voltage thaum them nyiaj yog hu uaCharge Cutoff Voltage;
- Thaum them nyiaj nres, cov polarization sab hauv ploj, thiab qhov hluav taws xob ib txwm poob rau hauvQhib Circuit Court voltage;
- LiFePO₄ hlwb feem ntau them txog 3.5-3.6V, tab sis lawvtswj tsis tau qib nontev. Xwb, lawv stabilize ntawm lub platform voltage ntawm3.2V thiab 3.4V.
Qhov no yog vim li cas qhov voltage zoo li "poob" tam sim tom qab them nyiaj.
2. Puas yog Voltage poob cuam tshuam rau lub peev xwm?
Qee cov neeg siv txhawj xeeb tias qhov kev poob qis no tuaj yeem txo cov roj teeb uas siv tau. Qhov tseeb:
- Cov roj teeb ntse lithium muaj cov txheej txheem tswj hwm uas raug ntsuas thiab kho lub peev xwm;
- Bluetooth-enabled apps tso cai rau cov neeg siv saib xyuasqhov tseeb khaws cia zog(piv txwv li, siv tau lub zog tawm), thiab rov kho SOC (State of Charge) tom qab txhua tus nqi tag nrho;
- Yog li ntawd,voltage poob tsis ua rau txo cov peev xwm siv tau.
3. Thaum twg yuav tsum ceev faj txog Voltage poob
Thaum qhov hluav taws xob poob qis yog qhov qub, nws tuaj yeem ua rau exaggerated nyob rau hauv tej yam kev mob:
- Kub cuam tshuam: Kev them nyiaj rau qhov kub siab lossis tshwj xeeb tshaj yog qis tuaj yeem ua rau muaj hluav taws xob sai dua;
- Kev laus ntawm tes: Ua kom muaj kev tiv thaiv sab hauv lossis siab dua tus kheej tawm tus nqi kuj tuaj yeem ua rau lub zog poob sai dua;
- Yog li cov neeg siv yuav tsum ua raws li cov kev siv kom raug thiab saib xyuas cov roj teeb tsis tu ncua.
Xaus
Voltage poob yog ib qho tshwm sim hauv cov roj teeb lithium, tshwj xeeb hauv LiFePO₄ hom. Nrog rau kev tswj hwm roj teeb siab heev thiab cov cuab yeej saib xyuas ntse, peb tuaj yeem ua kom muaj tseeb ntawm kev nyeem ntawv muaj peev xwm thiab kev noj qab haus huv mus sij hawm ntev thiab kev nyab xeeb ntawm lub roj teeb.
