Supercapacitor modulesfeem ntau ntsib teeb meem ntawm voltage imbalance ntawm hlwb.Lub npe hu ua supercapacitor module yog ib qho module uas muaj ntau lub supercapacitor;Vim tias qhov tsis sib xws ntawm supercapacitor yog qhov nyuaj ua kom zoo ib yam, qhov tsis sib xws ntawm qhov hluav taws xob yog qhov tshwm sim, thiab qee qhov supercapacitor tuaj yeem ntsib overvoltage, uas cuam tshuam rau cov khoom tsim tawm thiab lub neej ntawm supercapacitor, thiab tseem ua rau tsis ua haujlwm.
Nyob rau hauv tus txheej txheem ntawm daim ntawv thov supercapacitor, voltage ntsuas yog tsim nyog.Lub tshuab ntsuas hluav taws xob uas twb muaj lawm yog muab faib ua ob pawg: passive balancing thiab nquag ntsuas.
Passive Balancing
Passive ntsuas yog siv cov resistors thiab semiconductor keyboards lossis diodes kom sib npaug ntawm qhov hluav taws xob, thiab ua lub luag haujlwm ntawm kev tiv thaiv overvoltage los ntawm kev siv lub zog ntau dhau ntawm high-voltage supercapacitor.Feem ntau suav nrog kev sib npaug ntawm cov resistor ntsuas, hloov qhov ntsuas qhov ntsuas, thiab qhov ntsuas hluav taws xob ntsuas lub raj ntsuas.
Ntawm no peb tsuas yog tham txog qhov yooj yim tshaj plaws thaum uas tig mus resistor voltage ntsuas (dynamic yam ntxwv tsis zoo heev):
Req yog qhov ntsuas qhov sib npaug, uas yog txuas ncaj qha mus rau qhov sib npaug nrog lub cell supercapacitor.Thaum lub sij hawm them tus txheej txheem ntawm lub module, lub xov tooj ntawm tes kuj tseem tso tawm los ntawm Req, thiab lub xov tooj ntawm tes nrog high voltage tawm sai, yog li ua lub luag hauj lwm ntawm kev sib npaug tiv thaiv.Ntawm no, raws li kev sib txawv ntawm kev them nqi (kev them nqi hluav taws xob tsis tu ncua thiab kev them nyiaj tam sim no, ob qho tib si tuaj yeem siv dav hauv kev siv tswv yim), kuj tseem muaj qhov sib txawv ntawm cov qauv rau kev xaiv Req.
Tsis tu ncua voltage them
Piv txwv tias qhov them nqi hluav taws xob yog U, txij li qhov voltage ntawm lub supercapacitor module nyob rau hauv lub xeev khov kho yog qhov pib faib raws li EPR (kwv yees qhib Circuit Court tom qab C tau them tag nrho, thiab ESR tsawg heev), tom qab ntxiv Req, nws tuaj yeem ua tau. Qhov tseeb yuav nkag siab tias hloov EPR nrog Req, yog li Req yuav tsum xaiv cov resistors nrog sib npaug sib npaug thiab me dua EPR, kom qhov kev sib txuas ua ke tuaj yeem ua lub luag haujlwm tseem ceeb (feem ntau 0.01 ~ 0.1EPR).Qhov voltage ntawm lub supercapacitor ntawm lub xeev khov kho yog ReqU / (nReq).
Kev them nyiaj tam sim no tsis tu ncua
Piv txwv tias qhov them tam sim no yog kuv, txhua tus supercapacitor cell thiab Req tsim ib lub voj voog cais.Thaum qhov hluav taws xob ntawm lub capacitor cell nce, qhov tam sim no ntws los ntawm lub capacitor cell poob, thiab tam sim no ntws los ntawm Req nce.Thaum lub capacitor tau them tag nrho, qhov tam sim no ntawm lub capacitor yog 0, thiab lub cell voltage ntawm lub capacitor yog ReqI, uas yog, thaum lub cell voltages ntawm tag nrho cov series capacitors ncav cuag ReqI, qhov ntsuas yog tiav.Yog li, tus nqi ntawm qhov ntsuas qhov ntsuas yog Req = U (rated) / I.
Active Balancing
Active ntsuas yog hloov lub zog ntawm lub siab dua voltage cell los yog tag nrho cov module mus rau lwm lub hlwb kom txog rau thaum lub voltage ntawm tag nrho cov hlwb yog balanced.Feem ntau, qhov poob yog qhov tsawg, tab sis tus qauv tsim yuav nyuaj dua.Feem ntau yog DC / DC converter ntsuas, tshwj xeeb super capacitor tswj chips, thiab lwm yam.
