Inkqubo yokulawula ibhetri ye-BMS imane nje ingumphathi webhetri, idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukwandisa ubomi benkonzo kunye nokuqikelela amandla aseleyo. Lilungu elibalulekileyo lamandla kunye nogcino lweepakethi zebhetri, ukwandisa ubomi bebhetri ukuya kwinqanaba elithile kunye nokunciphisa ilahleko ebangelwa ngumonakalo webhetri.
Iinkqubo zolawulo lwebhetri yokugcina amandla zifana kakhulu neenkqubo zolawulo lwebhetri yamandla. Uninzi lwabantu aluwazi umahluko phakathi kwenkqubo yokulawula ibhetri yeBMS kunye nenkqubo yolawulo yeBMS yokugcina ibhetri. Okulandelayo, isingeniso esifutshane kwiiyantlukwano phakathi kweenkqubo zokulawula ibhetri ye-BMS kunye ne-BMS yokugcina ibhetri ye-BMS.
1. Ibhetri kunye nenkqubo yolawulo yayo izikhundla ezahlukeneyo kwiinkqubo ezifanelekileyo
Kwinkqubo yokugcina amandla, ibhetri yokugcina amandla isebenzisana kuphela nesiguquli sokugcina amandla ombane aphezulu, esithatha amandla kwigridi ye-AC kwaye ibize ipakethi yebhetri, okanye ipakethi yebhetri ibonelela ngesiguquli kwaye amandla ombane aguqulelwe kwigridi ye-AC. ngokusebenzisa isiguquli.
Inkqubo yokunxibelelana kunye nebhetri yenkqubo yokugcina amandla inolwazi lokusebenzisana ngokukodwa kunye nomguquli kunye nenkqubo yokucwangcisa isityalo sokugcina amandla.Kwelinye icala, inkqubo yolawulo lwebhetri ithumela ulwazi olubalulekileyo lobume kumguquli ukuze kubonwe ubume bonxibelelwano lwamandla aphezulu-voltage kwaye, kwelinye icala, inkqubo yolawulo lwebhetri ithumela olona lwazi lubanzi lokubeka iliso kwiPCS, ukuthumela. inkqubo yogcino lwamandla.
I-BMS yemoto yombane inobudlelwane botshintshiselwano lwamandla kunye nemoto yombane kunye netshaja ngokubhekiselele kunxibelelwano kwi-voltage ephezulu, inolwazi lokusebenzisana kunye neshaja ngexesha lenkqubo yokutshaja kwaye inolwazi oluthe kratya lokusebenzisana kunye nomlawuli wesithuthi ngexesha lazo zonke izicelo.
2. Isakhiwo esinengqiqo se-hardware sihluke
Kwiinkqubo zolawulo lokugcinwa kwamandla, i-hardware ngokubanzi ikwimowudi enemigangatho emibini okanye emithathu, enomlinganiselo omkhulu ojonge kwiinkqubo zolawulo lwamanqanaba amathathu. Iinkqubo zolawulo lwebhetri yamandla anomaleko omnye kuphela we-centralized or two layers of distributed, kwaye phantse akukho maleko amathathu.Izithuthi ezincinci zisebenzisa iinkqubo zolawulo lwebhetri kwindawo enye. Inkqubo yolawulo lwebhetri yamandla enemigangatho emibini.
Ukususela kumbono wokusebenza, iimodyuli zokuqala kunye neyesibini zenkqubo yokulawula ibhetri yokugcina amandla zilingana nemodyuli yokuqala yokuqokelela umaleko kunye nemodyuli yesibini yokulawula ibhetri yebhetri yamandla. Uluhlu lwesithathu lwenkqubo yokulawula ibhetri yogcino luluhlu olongezelelweyo phezu koku, ukujamelana nomlinganiselo omkhulu webhetri yokugcina. Ibonakaliswe kwinkqubo yokulawula ibhetri yokugcina amandla, lo mandla okulawula amandla okubalwa kwe-chip kunye nobunzima beprogram yesofthiwe.
3. Iiprothokholi zonxibelelwano ezahlukeneyo
Inkqubo yolawulo lwebhetri yokugcina amandla kunye nonxibelelwano lwangaphakathi lusebenzisa iprotocol ye-CAN, kodwa ngonxibelelwano lwangaphandle, lwangaphandle lubhekiselele ikakhulu kwisixhobo sokucwangcisa amandla okugcina amandla enkqubo yePCS, ikakhulu kusetyenziswa iprotocol ye-Intanethi yeTCP / IP protocol.
Ibhetri yamandla, indawo eqhelekileyo yezithuthi zombane ezisebenzisa i-CAN protocol, kuphela phakathi kwamacandelo angaphakathi kwi-pack yebhetri usebenzisa i-CAN yangaphakathi, ibhetri yepakethe kunye nesithuthi sonke phakathi kokusetyenziswa kwesithuthi sonke i-CAN ukuhlula.
I-4.Iintlobo ezahlukeneyo zee-cores ezisetyenziselwa izityalo zokugcina amandla, iiparamitha zenkqubo yokulawula ziyahluka kakhulu
Izikhululo zamandla okugcina amandla, zithathela ingqalelo ukhuseleko kunye noqoqosho, khetha iibhetri ze-lithium, ubukhulu becala i-lithium iron phosphate, kunye nezikhululo zamandla okugcina amandla amaninzi zisebenzisa iibhetri ezikhokelayo kunye neebhetri zekhabhoni. Uhlobo lwebhetri oluqhelekileyo lwezithuthi zombane ngoku i-lithium iron phosphate kunye neebhetri ze-ternary lithium.
Iindidi ezahlukeneyo zebhetri zineempawu zangaphandle ezahlukileyo kwaye iimodeli zebhetri aziqhelekanga kwaphela. Iisistim zolawulo lwebhetri kunye neeparitha ezingundoqo kufuneka zihambelane enye kwenye. Iiparamitha ezicacileyo zisetelwe ngokwahlukileyo kuhlobo olufanayo lwesiseko esiveliswa ngabavelisi abahlukeneyo.
5. Iintsingiselo ezahlukeneyo kwi-threshold setting
Izikhululo zamandla okugcina amandla, apho isithuba sininzi, sinokuthwala iibhetri ezininzi, kodwa indawo ekude yezinye izitishi kunye nokuphazamiseka kokuthutha kwenza kube nzima ukutshintsha iibhetri kwizinga elikhulu. Ulindelo lwesikhululo samandla sokugcina amandla kukuba iiseli zebhetri zinobomi obude kwaye aziphumeleli. Ngesi siseko, umda ophezulu womsebenzi wabo wangoku ubekwe phantsi ukuphepha umsebenzi womthwalo wombane. Iimpawu zamandla kunye neempawu zamandla zeeseli akufuneki zibe zifuna kakhulu. Into ephambili ekufuneka ijongwe kukusebenza kweendleko.
Iiseli zamandla zahlukile. Kwisithuthi esinendawo encinci, ibhetri elungileyo ifakwe kwaye ubuninzi bomthamo wayo bufunwa. Ke ngoko, iiparamitha zesistim zibhekisa kumda weeparamitha zebhetri, ezingalunganga kwibhetri kwiimeko ezinjalo zosetyenziso.
6. Ezi zimbini zifuna iiparamitha zikarhulumente ezahlukeneyo ukuba zibalwe
I-SOC yiparameter karhulumente ekufuneka ibalwe ngazo zombini. Nangona kunjalo, kude kube namhlanje, akukho mfuneko efanayo kwiinkqubo zokugcina amandla. Ngawaphi amandla okubala iparameter karhulumente efunekayo kwiinkqubo zolawulo lwebhetri yokugcina amandla? Ukongeza, indawo yokusetyenziswa kweebhetri zogcino lwamandla ityebile ngokwendawo kwaye izinzileyo, kwaye ukuphambuka okuncinci kunzima ukukubona kwinkqubo enkulu. Ke ngoko, iimfuno zokukwazi ukubala kwiinkqubo zolawulo lwebhetri yogcino lwamandla zingaphantsi kunezo zeenkqubo zolawulo lwebhetri yamandla, kwaye iindleko zolawulo lomtya omnye ohambelanayo azikho phezulu njengeebhetri zamandla.
7. Iisistim zolawulo lwebhetri yogcino lwamandla Ukusetyenziswa kweemeko ezilungileyo zokulinganisa i-passive
Izikhululo zamandla okugcina amandla zinemfuno engxamisekileyo yokulinganisa umthamo wenkqubo yolawulo. Iimodyuli zebhetri yokugcina amandla zinkulu ngokwesayizi, zineentambo ezininzi zeebhetri eziqhagamshelwe kuthotho. Umahluko omkhulu wombane omnye unciphisa umthamo webhokisi yonke, kwaye okukhona iibhetri ezininzi kuthotho, kokukhona ziphulukana nomthamo. Ukusuka kwindawo yokujonga ukusebenza kakuhle kwezoqoqosho, izityalo zokugcina amandla kufuneka zilingane ngokwaneleyo.
Ukongeza, ukulinganisa okungahambiyo kunokusebenza ngakumbi kunye neendawo ezininzi kunye neemeko ezilungileyo ze-thermal, ukuze kusetyenziswe imisinga emikhulu yokulinganisa ngaphandle koloyiko lokunyuka kobushushu obugqithisileyo. Ixabiso eliphantsi le-passive balancing linokwenza umahluko omkhulu kwizityalo zamandla zokugcina amandla.
