Lub voj voog tiv thaiv ntawm lub lithium solar cell muaj ib lub IC tiv thaiv thiab ob lub hwj chim MOSFETs. Lub IC tiv thaiv saib xyuas lub roj teeb voltage thiab hloov mus rau lub hwj chim MOSFET sab nraud yog tias muaj overcharge thiab discharge. Nws cov haujlwm suav nrog kev tiv thaiv overcharge, kev tiv thaiv over-discharge, thiab Overcurrent/Short Circuit Protection.
Cov cuab yeej tiv thaiv overcharge.
Lub hauv paus ntsiab lus ntawm kev tiv thaiv overcharge IC yog raws li nram no: thaum lub charger sab nraud tab tom them lub lithium solar cell, nws yog qhov tsim nyog yuav tsum tsis txhob ntseeg siab kom tiv thaiv lub siab sab hauv los ntawm kev nce vim qhov kub nce. Lub sijhawm no, kev tiv thaiv IC yuav tsum ntes lub roj teeb lub zog. Thaum nws mus txog (xav tias qhov overcharge ntawm lub roj teeb yog), kev tiv thaiv overcharge tau lees paub, lub zog MOSFET tau qhib thiab kaw, thiab tom qab ntawd kev them raug kaw.
1.Tsis txhob cia qhov kub thiab txias heev. Cov roj teeb hnub ci Lithium rhiab heev rau qhov kub thiab txias heev, yog li nws yog ib qho tseem ceeb kom paub tseeb tias lawv tsis raug rau qhov kub thiab txias qis dua 0°C lossis siab dua 45°C.
2.Tsis txhob muaj av noo ntau. Av noo ntau tuaj yeem ua rau cov lithium cell xeb, yog li nws yog ib qho tseem ceeb kom khaws cia rau hauv qhov chaw qhuav.
3.Khaws lawv kom huv. Cov av qias neeg, hmoov av, thiab lwm yam khoom tsis huv tuaj yeem txo qhov ua haujlwm ntawm cov cell, yog li nws yog ib qho tseem ceeb kom khaws lawv kom huv thiab tsis muaj hmoov av.
4.Tsis txhob raug kev poob siab. Kev poob siab tuaj yeem ua rau cov hlwb puas tsuaj, yog li nws tseem ceeb heev kom tsis txhob poob lossis ntaus lawv.
5.Tiv thaiv kom tsis txhob raug tshav ntuj ncaj qha. Kev tshav ntuj ncaj qha tuaj yeem ua rau cov cell kub dhau thiab puas tsuaj, yog li nws yog ib qho tseem ceeb uas yuav tsum tiv thaiv lawv kom tsis txhob raug tshav ntuj ncaj qha thaum twg ua tau.
6.Siv lub thawv tiv thaiv. Nws yog ib qho tseem ceeb uas yuav tsum khaws cov cell rau hauv lub thawv tiv thaiv thaum tsis siv kom tiv thaiv lawv ntawm cov huab cua.
Tsis tas li ntawd xwb, yuav tsum tau ceev faj txog qhov ua tsis tau zoo ntawm kev kuaj pom overcharge vim muaj suab nrov kom tsis txhob raug txiav txim siab tias yog kev tiv thaiv overcharge. Yog li ntawd, yuav tsum teeb tsa lub sijhawm ncua, thiab lub sijhawm ncua yuav tsum tsis pub tsawg dua lub sijhawm suab nrov.
