Ngaba wakha wazibuza ukuba indlelaI-BMSNgaba iyakwazi ukubona umsinga webhetri ye-lithium? Ngaba kukho i-multimeter eyakhelwe kuyo?
Okokuqala, kukho iintlobo ezimbini zeNkqubo yoLawulo lweBhetri (i-BMS): iinguqulelo ezikrelekrele kunye neenguqulelo zehardware. Yi-BMS ekrelekrele kuphela enokukwazi ukudlulisa ulwazi lwangoku, ngelixa inguqulelo yehardware ingenalo.
I-BMS idla ngokuba nesekethe edibeneyo yokulawula (i-IC), iiswitshi ze-MOSFET, iisekethe zokujonga zangoku, kunye neesekethe zokujonga ubushushu. Icandelo eliphambili lenguqulelo ehlakaniphileyo yi-IC yokulawula, esebenza njengengqondo yenkqubo yokukhusela. Inoxanduva lokujonga umbane webhetri ngexesha langempela. Ngokuqhagamshela nesekethe yokujonga yangoku, i-IC yokulawula inokufumana ngokuchanekileyo ulwazi malunga nombane webhetri. Xa umbane udlula imida yokhuseleko emiselweyo, i-IC yokulawula yenza isigqibo ngokukhawuleza kwaye iqalise izenzo zokukhusela ezifanelekileyo.
Ngoko ke, ifunyanwa njani i-current?
Ngokwesiqhelo, i-Hall effect sensor isetyenziselwa ukujonga umbane. Le sensor isebenzisa ubudlelwane phakathi kwamacandelo emagnethi kunye nombane. Xa umbane uhamba, kwenziwa i-magnetic field ejikeleze i-sensor. I-sensor ikhupha isignali ye-voltage ehambelanayo ngokusekelwe kumandla e-magnetic field. Nje ukuba i-IC yokulawula ifumane esi signali ye-voltage, ibala ubungakanani bombane bokwenyani isebenzisa ii-algorithms zangaphakathi.
Ukuba umbane udlula ixabiso lokhuseleko elimiselweyo, elifana nombane ogqithisileyo okanye umbane omfutshane, i-IC yokulawula iya kulawula ngokukhawuleza iiswitshi ze-MOSFET ukuze inqumle indlela yangoku, ikhusela ibhetri kunye nenkqubo yesekethe yonke.
Ukongeza, i-BMS ingasebenzisa ezinye ii-resistor kunye nezinye izinto ukunceda ekujongeni umbane. Ngokulinganisa ukuhla kwe-voltage kwi-resistor, ubungakanani bamandla bunokubalwa.
Olu luhlu lweendlela zoyilo lwesekethe ezintsonkothileyo nezichanekileyo kunye neendlela zokulawula zonke zijolise ekujongeni amandla ebhetri ngelixa zikhusela kwiimeko zoxinzelelo olugqithisileyo. Zidlala indima ebalulekileyo ekuqinisekiseni ukusetyenziswa ngokukhuselekileyo kweebhetri ze-lithium, ukwandisa ubomi bebhetri, kunye nokuphucula ukuthembeka kwenkqubo yebhetri yonke, ngakumbi kwizicelo zeLiFePO4 kunye nezinye iinkqubo zeBMS series.
