Isixhumanisi Esibalulekile Esixhuma Amabhethri Amandla Nezimoto zikagesi – BMS (Isistimu Yokulawula Ibhethri)-1

 

1.Yini i-BMS Battery Management System?

I-BMS Battery Management System isetshenziselwa kakhulu ukuphatha nokunakekela amayunithi ebhethri ngobuhlakani, ukuvimbela ukushajwa ngokweqile nokushajwa ngokweqile kwamabhethri, ukwelula impilo yebhethri, nokuqapha isimo sebhethri.

2.Izingxenye ze-BMS

I-BMS yakhiwe ngokuyinhloko isilawuli esiyinhloko se-BMU, isilawuli esingaphansi kwe-CSC, imojula yokulinganisa ye-CSU, isilawuli se-HVU high-voltage, iyunithi yesikhombi sesimo sebhethri ye-BTU, kanye nemojula yokuxhumana ye-GPS.

3.Ifomu lomjikelezo wempilo we-BMS

IbhethriI-Management System (BMS) iyingxenye ebalulekile yezimoto zikagesi nezinye izinhlelo zebhethri. Inesibopho sokuqapha nokulawula isimo sebhethri ukuze kuqinisekiswe ukusebenza okuphephile nokusebenza kahle. Umjikelezo wempilo ka-aI-BMSzingahlukaniswa izigaba eziningana:

• Isigaba sokuklama: Ngesikhathi sesigaba sokuklama i-BMS, umsebenzi we-BMS nokucushwa kufanele kunqunywe ngokusekelwe ezintweni ezifana nohlobo lwebhethri, isimo sohlelo lokusebenza, kanyeizidingo zokusebenza. Lesi sigaba sidinga ucwaningo olunzulu nokuhlolwa ukuze kuqinisekiswe ukuthiIdizayini ye-BMSihlangabezana nezidingo zohlelo lwebhethri.

 

• Isiteji sokukhiqiza: Ngesikhathi sesigaba sokukhiqiza i-BMS, izingxenye ezehlukene ze-BMS kumele zikhiqizwe ngokwezidingo zomklamo futhi zihlanganiswe futhi zihlolwe. Lesi sigaba sidinga ukulawulwa kwekhwalithi okuqinile ukuze kuqinisekiswe ukuthi ikhwalithi nokusebenza kwe-BMS kuhlangabezana nezidingo zokuklama.

 

• Isiteji sokufaka nokulungisa iphutha: Ngesikhathi sohleloUkufakwa kwe-BMSfuthiisigaba sokulungisa iphutha, i-BMS kufanele ifakwe ohlelweni lwebhethri futhi ihlolwe futhi ilungiswe. Lesi sigaba sidinga ukunakekelwa okukhulu nokunemba ukuze kuqinisekiswe ukuthi ukufakwa nokulungisa iphutha kwe-BMS akulimazi ibhethri noma kuthikameze ukusebenza kwayo.

 

• Isigaba sokusebenza nokulungisa: Ngesikhathi sokusebenza nokulungiswa kwe-BMS, kufanele kuhlolwe njalo futhi kulungiswe ukuze kuqinisekiswe ukusebenza okuvamile nokusebenza kwe-BMS. Lesi sigaba sidinga ukuqoshwa kwedatha nokuhlaziywa ukuze kutholakale ngokushesha futhi kuxazululwe izinkinga kanye nokuthuthukisa nokugcina i-BMS.

 

• Umhlalaphansifuthiisiteji sokuvuselela: Ngesikhathi sokuthatha umhlalaphansi kwe-BMS kanye nesigaba sokuvuselela, i-BMS kufanele ibuyekezwe noma ishintshwe ngokusekelwe kubude bempilo yebhethri nokusebenza kwayo. Lesi sigaba sidingaukuhlaziya idathakanye nokuhlola ukuze kutholwe ukuthi i-BMS idinga ukubuyekezwa noma ukushintshwa kanye nendlela yokuvuselela noma ukufaka esikhundleni i-BMS.

 

4.Imisebenzi esemqoka yesoftware ye-BMS

Umsebenzi wokulinganisa

(1) Isilinganiso solwazi oluyisisekelo: ukuqapha umthamo webhethri, isignali yamanje, nezinga lokushisa lephakethe lebhethri. Umsebenzi oyisisekelo kakhulu wohlelo lokuphatha ibhethri ukukala amandla kagesi, amandla amanje, kanye nezinga lokushisa lamaseli ebhethri, okuyisisekelo sazo zonke izibalo ezisezingeni eliphezulu kanye nokucabanga kokulawula kohlelo lokuphatha amabhethri.

(2) Ukutholwa kokumelana nokushisisa: Lonke isistimu yebhethri kanye nesistimu ye-voltage ephezulu idinga ukuhlolelwa ukwahlukanisa ngohlelo lokuphatha ibhethri.

(3) Ukutholwa kwe-high-voltage interlock (HVIL): isetshenziselwa ukuqinisekisa ubuqotho bayo yonke isistimu ye-high-voltage. Uma ubuqotho besifunda sesistimu ye-voltage ephezulu bonakalisiwe, izinyathelo zokuphepha ziyasebenza.

Umsebenzi wokulinganisa

(1) Ukulinganisa kwe-SOC ne-SOH: ingxenye ewumgogodla nenzima kakhulu

(2) Ukulinganisa: lungisa ukungalingani komthamo we-SOC x phakathi kwama-monomer ngokusebenzisa isekethe yokulinganisa.

(3) Umkhawulo wamandla ebhethri: amandla okufaka nawokukhiphayo ebhethri anomkhawulo emazingeni okushisa e-SOC ahlukene.

Eminye imisebenzi

(1) Isilawuli sokudlulisa: okuhlanganisa okuyinhloko +, okuyinhloko-, ukudluliselwa kokushaja +, ukudluliselwa kokushaja -, ukudluliswa kokushaja kwangaphambili

(2) Ukulawula ukushisa

(3) Umsebenzi wokuxhumana

(4) Ukuxilongwa kwephutha kanye ne-alamu

(5) Ukusebenza okubekezelela amaphutha
