Inkqubo yolawulo lwebhetri yeBMS sisixhobo esinamandla sokuphucula ubomi beebhetri zesixokelelwano selanga. Inkqubo yolawulo lwebhetri yeBMS ikwanceda ekuqinisekiseni ukuba iibhetri zikhuselekile kwaye zithembekile. Apha ngezantsi kukho ingcaciso enzulu yenkqubo ye-BMS kunye neenzuzo ezifunyanwa ngabasebenzisi.
Isebenza njani iNkqubo ye-BMS
I-BMS yeebhetri ze-lithium isebenzisa ikhompyutha ekhethekileyo kunye nezinzwa zokulawula indlela ibhetri esebenza ngayo. Izinzwa zovavanyo lobushushu, izinga lokutshaja, umthamo webhetri, nokunye. Ikhompyutha ekwibhodi yesistim ye-BMS emva koko yenza izibalo ezilawula ukutshajwa kunye nokukhutshwa kwebhetri. Injongo yalo kukuphucula ubomi benkqubo yokugcina ibhetri yelanga ngelixa uqinisekisa ukuba ikhuselekile kwaye inokwethenjelwa ukusebenza.
Amacandelo eNkqubo yoLawulo lwebhetri
Inkqubo yolawulo lwebhetri ye-BMS iquka izinto ezininzi ezibalulekileyo ezisebenza kunye ukunikezela ngeyona ndlela ifanelekileyo yokusebenza kwibhetri. Amacandelo ngala:
Itshaja yebhetri
Itshaja ifaka amandla kwipakethi yebhetri ngevoltheji echanekileyo kunye nesantya sokuhamba kwayo ukuqinisekisa ukuba itshajwe ngokufanelekileyo.
Ukujongwa kwebhetri
Isixhobo sokujonga ibhetri sisisuti sezivamvo ezibeka iliso kwimpilo yebhetri kunye nolunye ulwazi olubalulekileyo njengemo yokutshaja kunye nobushushu.
Umlawuli webhetri
Umlawuli ulawula ukutshaja kunye nokukhupha ipakethi yebhetri. Iqinisekisa ukuba amandla angena kwaye ashiye ipakethi yebhetri ngokufanelekileyo.
Izihlanganisi
Ezi ziqhagamshelanisi ziqhagamshela inkqubo ye-BMS, iibhetri, i-inverter, kunye nepaneli yelanga. Iqinisekisa ukuba i-BMS inokufikelela kulo lonke ulwazi oluvela kwisixokelelwano sokukhanya kwelanga.
Iimpawu zeNkqubo yoLawulo lwebhetri yeBMS
Yonke i-BMS yeebhetri ze-lithium ineempawu zayo ezizodwa. Nangona kunjalo, iimpawu zayo ezimbini ezibalulekileyo zikhusela kwaye zilawula umthamo webhetri. Ukukhuselwa kwebhetri yepakethe kufezekiswa ngokuqinisekisa ukukhuselwa kombane kunye nokukhuselwa kwe-thermal.
Ukukhuselwa kombane kuthetha ukuba inkqubo yokulawula ibhetri iya kuvala ukuba indawo yokusebenza ekhuselekileyo (SOA) igqithile. Ukukhuselwa kwe-thermal kunokusebenza okanye ukulawulwa kweqondo lokushisa okungapheliyo ukugcina ipakethe yebhetri ngaphakathi kwe-SOA yayo.
Ngokuphathelele ulawulo lwebhetri, i-BMS yeebhetri ze-lithium yenzelwe ukwandisa umthamo. Ibhetri iya kuba lilize ukuba akwenziwanga ulawulo lwamandla.
Imfuneko yolawulo lomthamo kukuba ibhetri nganye ekwipakethi yebhetri inomsebenzi owahluke kancinane. Lo mahluko wokusebenza uphawuleka kakhulu kumazinga okuvuza. Xa isitsha, ipakethi yebhetri inokusebenza kakuhle. Nangona kunjalo, ngokuhamba kwexesha, umahluko ekusebenzeni kweeseli zebhetri uyanda. Ngenxa yoko, kunokukhokelela kumonakalo wokusebenza. Isiphumo ziimeko zokusebenza ezingakhuselekanga kuyo yonke ipakethi yebhetri.
Isishwankathelo, inkqubo yokulawula ibhetri ye-BMS iya kususa intlawulo kwiiseli ezihlawuliswa kakhulu, ezithintela ukugqithiswa. Ikwavumela iiseli ezingahlawuliswanga kakhulu ukuba zifumane umsinga wokutshaja.
I-BMS yeebhetri ze-lithium iyakuphinda iqondise enye okanye phantse wonke umsinga wokutshaja ojikeleze iiseli ezitshajiweyo. Ngenxa yoko, iiseli ezingahlawuliswanga kancinci zifumana umsinga wokutshaja ixesha elide.
Ngaphandle kwenkqubo yolawulo lwebhetri ye-BMS, iiseli ezitshaja kuqala ziya kuqhubeka zihlawulisa, nto leyo enokukhokelela ekufudumezweni. Ngelixa iibhetri ze-lithium zibonelela ngokusebenza okugqwesileyo, zinengxaki yokufudumeza ngokugqithisileyo xa kuziswa ngokugqithisileyo ngoku. Ukugqithisa ibhetri ye-lithium kunciphisa kakhulu ukusebenza kwayo. Kwimeko embi kakhulu, kunokukhokelela ekungaphumelelini kwayo yonke ipakethe yebhetri.
Iindidi ze-BMS zeebhetri zeLithium
Iisistim zolawulo lwebhetri zinokulula okanye zibe nzima kakhulu kwiimeko ezahlukeneyo zokusetyenziswa kunye nobuchwepheshe. Nangona kunjalo, zonke zijolise ekunyamekeleni ipakethe yebhetri. Ezona zigaba zixhaphakileyo zezi:
