Ingcamango yeiseli balancingmhlawumbi iqhelekile kuninzi lwethu. Oku kungenxa yokuba ukuhambelana kwangoku kweeseli akulunganga ngokwaneleyo, kwaye ukulinganisa kunceda ukuphucula oku. Kanye njengokuba awukwazi ukufumana amagqabi amabini afanayo emhlabeni, awukwazi ukufumana iiseli ezimbini ezifanayo. Ke, ekugqibeleni, ukulungelelanisa kukujongana neziphene zeeseli, zisebenza njengomlinganiselo wembuyekezo.
Yeyiphi imiba ebonisa ukungangqinelani kweSeli?
Kukho iinkalo ezine eziphambili: iSOC (iState of Charge), ukuchasana kwangaphakathi, ukuzikhupha ngoku, kunye nomthamo. Nangona kunjalo, ukulinganisa akunako ukusombulula ngokupheleleyo ezi ntlukwano zine. Ukulinganisa kunokuhlawula kuphela iyantlukwano ye-SOC, ngengozi ukujongana nokungahambelani kokuzikhupha. Kodwa ngenxa yokuchasana kwangaphakathi kunye nomthamo, ukulinganisa akunamandla.
Kubangelwa Njani Ukungangqinelani Kweseli?
Kukho izizathu ezibini eziphambili: enye kukungahambelani okubangelwa ukuveliswa kweeseli kunye nokucubungula, kwaye enye kukungahambelani okubangelwa yindawo yokusetyenziswa kweeseli. Ukungangqinelani kwemveliso kuvela kwizinto ezifana neendlela zokucwangcisa kunye nemathiriyeli, into eyenza lula umba onzima kakhulu. Ukungahambelani kokusingqongileyo kulula ukuyiqonda, njengoko indawo nganye yeseli kwi-PACK yahlukile, ekhokelela kumahluko okusingqongileyo njengokwahluka okuncinci kwiqondo lokushisa. Ngokuhamba kwexesha, le yantlukwano iqokelelana, ibangela ukungangqinelani kweeseli.
Isebenza Njani I-Balanceing?
Njengoko bekutshiwo ngaphambili, ukulinganisa kusetyenziswa ukuphelisa iyantlukwano yeSOC phakathi kweeseli. Ngokufanelekileyo, igcina i-SOC yeseli nganye ifana, ivumela zonke iiseli ukuba zifikelele kwimida yombane ephezulu kunye nesezantsi yentlawulo kwaye ikhuphe ngaxeshanye, ngaloo ndlela isonyusa umthamo osebenzisekayo wepakethi yebhetri. Kukho iimeko ezimbini zomahluko we-SOC: enye kuxa amandla eseli afana kodwa ii-SOC zahlukile; enye kuxa iiseli capacities kunye neeSOCs zahlukene zombini.
Imeko yokuqala (ekhohlo kakhulu kumfanekiso ongezantsi) ibonisa iiseli ezinomthamo ofanayo kodwa ii-SOC ezahlukeneyo. Iseli ene-SOC encinci ifikelela kumda wokukhupha kuqala (ithatha i-25% ye-SOC njengomda ophantsi), ngelixa iseli ene-SOC enkulu ifikelela kumda wentlawulo kuqala. Ngokulinganisa, zonke iiseli zigcina i-SOC efanayo ngexesha lokuhlawuliswa kunye nokukhutshwa.
Imeko yesibini (eyesibini ukusuka ekhohlo kumfanekiso ongezantsi) ibandakanya iiseli ezinomthamo ohlukeneyo kunye nee-SOC. Apha, iseli enezona ntlawulo zincinci zomthamo kunye nokukhupha kuqala. Ngokulinganisa, zonke iiseli zigcina i-SOC efanayo ngexesha lokuhlawuliswa kunye nokukhutshwa.
Ukubaluleka Kokulungelelanisa
Ukulinganisa ngumsebenzi obalulekileyo kwiiseli zangoku. Kukho iindidi ezimbini zokulinganisa:ukulinganisa okusebenzayokwayeulungelelaniso lokwenziwa. I-Passive balancing isebenzisa izixhasi zokukhupha, ngelixa ukulinganisa okusebenzayo kubandakanya ukuhamba kwentlawulo phakathi kweeseli. Kukho ingxoxo malunga nala magama, kodwa asiyi kungena kuloo nto. I-Passive balancing isetyenziswa kakhulu xa kusenziwa, ngelixa ukulinganisa okusebenzayo kuqhelekile.
Ukugqiba ngeBancing Current for BMS
Ngokumalunga nokwenziwa kolungelelwaniso, kufuneka kumiselwe njani umsinga wokulinganisa? Ngokufanelekileyo, kufuneka ibe nkulu ngokusemandleni, kodwa izinto ezifana neendleko, ukutshatyalaliswa kobushushu, kunye nendawo zifuna ukuthobela.
Phambi kokukhetha i-bancing current, kubalulekile ukuqonda ukuba ingaba umahluko we-SOC ubangelwa yimeko enye okanye i-scenario yesibini. Kwiimeko ezininzi, isondele ngakumbi kwimeko enye: iiseli ziqala ngokufana nomthamo kunye ne-SOC, kodwa njengoko zisetyenziswa, ngakumbi ngenxa yokungafani kokuzikhupha, i-SOC yeseli nganye iyahluka ngokuthe ngcembe. Ngoko ke, amandla okulinganisa kufuneka ubuncinane aphelise impembelelo yokwahlukana kokuzimela.
Ukuba zonke iiseli bezizikhupha ngokufanayo, ukulinganisa bekungayi kuba yimfuneko. Kodwa ukuba kukho umahluko kwi-self-discharge yangoku, iya kuvela iyantlukwano ye-SOC, kwaye ulungelelwaniso luyafuneka ukuhlawulela oku. Ukongeza, kuba umndilili wexesha lokulinganisa imihla lilinganiselwe ngelixa ukuzikhupha kuyaqhubeka yonke imihla, ixesha elililo kufuneka liqwalaselwe.
