Ngaba wakha wazibuza ukuba njani aBMSiyakwazi ukubona okwangoku ipakethe yebhetri ye-lithium? Ngaba kukho i-multimeter eyakhelwe kuyo?
Okokuqala, kukho iindidi ezimbini zeeNkqubo zoLawulo lweBattery (BMS): iinguqulelo ze-smart kunye ne-hardware. Kuphela i-BMS ehlakaniphile inamandla okuhambisa ulwazi lwangoku, ngelixa i-hardware version ayinayo.
I-BMS idla ngokuba nesekethe edibeneyo yolawulo (IC), iiswitshi zeMOSFET, iisekethe zangoku zokubeka iliso, kunye neesekethe zokubeka iliso kubushushu. Inxalenye ephambili ye-smart version yi-IC yokulawula, esebenza njengengqondo yenkqubo yokukhusela. Inoxanduva lokujonga ixesha lokwenyani lebhetri yangoku. Ngokudibanisa nesekethe yangoku yokubeka iliso, i-IC yolawulo inokufumana ngokuchanekileyo ulwazi malunga nebhetri yangoku. Xa i-current idlula imida yokhuseleko olucwangcisiweyo, i-IC yokulawula ngokukhawuleza yenza isigwebo kwaye ibangele izenzo zokukhusela ezihambelanayo.
Ke, ibonwa njani ngoku?
Ngokuqhelekileyo, i-sensor effect yeHolo isetyenziselwa ukubeka iliso ngoku. Le sensor isebenzisa ubudlelwane phakathi kwemimandla yamagnetic kunye neyangoku. Xa ngoku kuqukuqela, umhlaba wemagnethi uveliswa ujikeleze inzwa. I-sensor ikhupha isignali yombane ehambelanayo ngokusekelwe kumandla omhlaba wemagnethi. Nje ukuba i-IC yolawulo ifumane lo mqondiso we-voltage, ibala ubungakanani obukhoyo ngoku usebenzisa i-algorithms yangaphakathi.
Ukuba i-current idlula ixabiso lokhuseleko olusethiweyo, njenge-overcurrent okanye i-short-circuit current, i-IC yolawulo iya kulawula ngokukhawuleza ii-switch ze-MOSFET ukunqumla indlela yangoku, ukukhusela zombini ibhetri kunye nenkqubo yesekethe yonke.
Ukongeza, i-BMS inokusebenzisa ezinye izixhasi kunye namanye amacandelo ukunceda ekubekeni iliso ngoku. Ngokulinganisa ukuhla kwamandla ombane kwi-resistor, ubungakanani bangoku bunokubalwa.
Olu luhlu loyilo lwesekethe olunzima kunye oluchanekileyo kunye neendlela zokulawula zonke zijolise ekubekeni iliso kwibhetri yangoku ngelixa zikhusela kwiimeko ezidlulayo. Badlala indima ebalulekileyo ekuqinisekiseni ukusetyenziswa ngokukhuselekileyo kweebhetri ze-lithium, ukwandisa ubomi bebhetri, kunye nokuphucula ukuthembeka kwayo yonke inkqubo yebhetri, ngakumbi kwizicelo ze-LiFePO4 kunye nezinye iinkqubo ze-BMS series.
