I-PCS (iNkqubo yokuGuqulwa kwamandla) inokulawula inkqubo yokutshaja kunye nokukhupha ibhetri, iqhube ukuguqulwa kwe-AC / DC, kunye nokubonelela ngokuthe ngqo amandla kwimithwalo ye-AC ngokungabikho kwegridi yamandla.PCS iquka i-DC/AC bi-directional converter, ulawulo. iyunithi, njl Umlawuli we-PCS ufumana umyalelo wokulawula umva ngonxibelelwano, kwaye ulawula umguquli ukuba ahlawule okanye akhuphe ibhetri ukuze aqonde ukulawulwa kwamandla asebenzayo kunye namandla asebenzayo kwigridi yamandla ngokweesimboli kunye nobukhulu bemiyalelo yamandla.Umlawuli we-PCS ufumana imiyalelo yolawulo lwangasemva ngonxibelelwano kwaye ulawula umguquli ukuba ahlawule okanye akhuphe ibhetri ngokuhambelana nomqondiso kunye nobukhulu bomyalelo wamandla, ukuze aqonde ukulawulwa kwamandla asebenzayo kunye namandla asebenzayo egridi yamandla.Umlawuli we-PCS unxibelelana ne-BMS nge-interface ye-CAN ukufumana ulwazi lwemeko yebhetri, enokuqonda ukutshaja okukhuselekileyo kunye nokukhupha ibhetri kunye nokuqinisekisa ukhuseleko lokusebenza kwebhetri.
Iyunithi yolawulo ye-PCS: Yenza iintshukumo ezifanelekileyo:
Undoqo wePCS nganye yiyunithi yolawulo, efumana imiyalelo yolawulo lwangasemva ngokusebenzisa amajelo onxibelelwano.Umlawuli okrelekrele utolika le miyalelo ngokuchanekileyo, evumela ukuba ibonise ukutshaja okanye ukukhupha ibhetri ngokusekelwe kumqondiso kunye nobukhulu bomyalelo wamandla.Okona kubaluleke kakhulu, iyunithi yokulawula ye-PCS ilawula ngokusebenzayo amandla asebenzayo kunye asebenzayo egridi ukuqinisekisa ukusebenza kakuhle.Unxibelelwano olungenamthungo phakathi komlawuli we-PCS kunye nenkqubo yolawulo lwebhetri (BMS) ngojongano lwe-CAN luphucula ngakumbi ukusebenza kwayo.
Ukukhusela ukusebenza kwebhetri: ukuqinisekisa ukhuseleko:
Uqhagamshelwano phakathi komlawuli we-PCS kunye ne-BMS ludlala indima ebalulekileyo ekukhuseleni ukusebenza kwebhetri.Ngokusebenzisa i-CAN interface, umlawuli we-PCS uqokelela ulwazi oluxabisekileyo lwexesha langempela malunga nobume bebhetri.Ngolu lwazi, inokuphumeza amanyathelo okukhusela ngexesha lokuhlawula kunye nokukhupha.Ngokujonga ngokusondeleyo iiparameters eziphambili ezifana nobushushu, i-voltage kunye nekhoyo ngoku, abalawuli be-PCS banciphisa umngcipheko wokutshaja okanye ukutshaja, ukuthintela umonakalo onokwenzeka kwibhetri.Olu khuseleko lwandisiweyo alwandisi nje kuphela ubomi bebhetri kodwa lukwanciphisa ithuba leziganeko ezingalindelekanga, ukunceda ukubonelela ngesisombululo esizinzileyo nesithembekileyo sokugcina amandla.
Iinkqubo zokuguqula amandla (PCS) ziyiguqule indlela esigcina ngayo kunye nokusetyenziswa kwamandla.Ngobuchule bayo obunamandla bokulawula ukutshaja kunye neenkqubo zokukhupha, ukwenza ukuguqulwa kwe-AC ukuya kwi-DC, kunye nokubonelela ngokuzimeleyo amandla kwimithwalo ye-AC, i-PCS iye yaba sisiseko seenkqubo zokugcina amandla zanamhlanje.Unxibelelwano olungenamthungo phakathi kweyunithi yokulawula ye-PCS kunye ne-BMS yenza ukuba ukutshaja okukhuselekileyo kunye nokukhupha ukuqinisekisa ukusebenza ngokukhuselekileyo kwebhetri.Xa sisebenzisa amandla e-PCS, sivula indlela yekamva elizinzileyo apho amandla ahlaziyekayo anokugcinwa kwaye avunwe ngeyona ndlela iphezulu yokusebenza nokuthembeka.
