1. Mekhoa ea ho Tsoha
Ha o qala, ho na le mekhoa e meraro ea ho tsoha (lihlahisoa tsa nako e tlang li ke ke tsa hloka ts'ebetso):
- Ho tsosoa ha konopo ea konopo;
- Ho tsosoa ha ts'ebetso ea ho tjhaja;
- Ho tsosa konopo ea Bluetooth.
Bakeng sa matla a latelang, ho na le mekhoa e tšeletseng ea ho tsosa:
- Ho tsosoa ha konopo ea konopo;
- Tsoho ya ho tjhaja (ha motlakase wa tjhaja o le bonyane 2V ho feta matla a betri);
- 485 ho tsosa puisano;
- KANna puisano tshebetso tsoha;
- Ho tsosoa ha ts'ebetso ea ho tlosa (hona joale ≥ 2A);
- Tsoho ya ho kenya tshebetsong.
2. Mokhoa oa ho robala oa BMS
TheBMSe kena ka mokhoa o fokolang oa matla (nako ea kamehla ke metsotsoana ea 3600) ha ho se na puisano, ho se na tefiso / ho ntša motlakase, 'me ho se na pontšo ea ho tsoha. Nakong ea mokhoa oa ho robala, ho tjhaja le ho ntša MOSFET ho lula ho hokahane ntle le haeba betri e sa sebetse hantle, ka nako eo li-MOSFET li tla khaola. Haeba BMS e lemoha matshwao a puisano kapa maqhubu a tjhaja/ho ntsha (≥2A, le ho kenya tshebetsong ho tjhaja, motlakase wa tjhaja o tlameha ho ba bonyane 2V ho feta matla a betri, kapa ho na le letshwao la ho tsoha), e tla araba hanghang mme kena boemong ba ho sebetsa ba ho tsoha.
3. Leano la Tekanyo ea SOC
Bokhoni ba sebele ba betri le xxAH bo behiloe ka har'a komporo e amohelang. Nakong ea ho tjhaja, ha motlakase oa sele o fihla ho boleng bo phahameng ba overvoltage mme ho na le ho tjhaja hona joale, SOC e tla lekanyetsoa ho 100%. (Nakong ea ho ntša, ka lebaka la liphoso tsa lipalo tsa SOC, SOC e kanna ea se be 0% leha maemo a alamo ea undervoltage a fihlelleha. Hlokomela: Leano la ho qobella SOC ho zero kamora ts'ireletso ea cell overdischarge (undervoltage) e ka etsoa ka mokhoa o ikhethileng.)
4. Phoso Ho sebetsana le Leano
Liphoso li arotsoe ka mekhahlelo e 'meli. BMS e sebetsana le maemo a fapaneng a liphoso ka tsela e fapaneng:
- Boemo ba 1: Liphoso tse nyane, BMS e lla feela.
- Boemo ba 2: Liphoso tse matla, lialamo tsa BMS le ho khaola switch ea MOS.
Bakeng sa liphoso tse latelang tsa Level 2, switch ea MOS ha e khaotsoe: alamo ea phapang e feteletseng ea motlakase, alamo ea phapang e feteletseng ea mocheso, alamo e phahameng ea SOC, le alamo e tlase ea SOC.
5. Ho leka-lekanya Taolo
Ho sebelisoa passive balancing. TheBMS e laola ho tsoa ha lisele tsa motlakase tse phahamengka lihanyetsi, ho qhala matla joalo ka mocheso. Ho leka-lekanya hona joale ke 30mA. Ho leka-lekanya ho qala ha maemo ohle a latelang a phethiloe:
- Nakong ea ho tjhaja;
- The balancing activation voltage e fihletsoe (setable ka k'homphieutha e amohelang); Phapang ea motlakase lipakeng tsa lisele> 50mV (50mV ke boleng ba kamehla, bo ka hlophisoang ka komporo e amohelang).
- Default activation voltage bakeng sa lithium iron phosphate: 3.2V;
- Default activation voltage bakeng sa ternary lithium: 3.8V;
- Default activation voltage bakeng sa lithium titanate: 2.4V;
6. Khakanyo ea SOC
BMS e hakanya SOC e sebelisa mokhoa oa ho bala oa coulomb, ho bokella tefiso kapa ho tsoa ho lekanya boleng ba betri ea SOC.
Phoso ea Khakanyo ea SOC:
| Ho nepahala | Sehlopha sa SOC |
|---|---|
| ≤ 10% | 0% < SOC < 100% |
7. Ho nepahala ha Voltage, Hona Joale, le Mocheso
| Mosebetsi | Ho nepahala | Yuniti |
|---|---|---|
| Motlakase oa lisele | ≤ 15% | mV |
| Kakaretso ea Voltage | ≤ 1% | V |
| Hona joale | ≤ 3% FSR | A |
| Mocheso | ≤2 | °C |
8. Tšebeliso ea Matla
- Ho itšehla thajana ha boto ea lisebelisoa ha u sebetsa: <500µA;
- Ho itšehla thajana ha boto ea software ha u sebetsa: <35mA (ntle le puisano ea kantle: <25mA);
- Mokhoa oa ho iphelisa ka mokhoa oa ho robala: <800µA.
9. Soft Switch le Key Switch
- Maikutlo a kamehla bakeng sa ts'ebetso ea switjha e bonolo ke logic e fapaneng; e ka ikamahanya le maemo a nepahetseng.
- Tshebetso ya kamehla ya senotlolo ke ho kenya tshebetsong BMS; mesebetsi e meng ea logic e ka etsoa customized.
