1. Hababka toosinta
Marka ugu horeysa ee la shido, waxaa jira seddex qaab oo toos ah (alaabta mustaqbalka uma baahna firfircooni):
- Soo kicinta badhanka;
- Dallacaadda kicinta kicinta;
- Baraarujinta badhanka Bluetooth
Korontada xigta, waxaa jira lix hab oo toos ah:
- Soo kicinta badhanka;
- Dallacaadda kicinta kicinta (marka korantada gelinta xeedhuhu uu ugu yaraan 2V ka sarreeyo tamarta batteriga);
- 485 kicinta kicinta isgaarsiinta;
- CAN kicinta kicinta isgaarsiinta;
- Soo kicinta kicinta dareeraha (hadda ≥ 2A);
- Soo kicin furaha.
2. Habka hurdada ee BMS
TheBMSwuxuu galaa qaab awood yar ah (waqtiga ugu talagalka ah waa 3600 ilbiriqsi) marka aysan jirin isgaarsiin, lacag la'aan/dadin hadda, iyo calaamad la'aan. Inta lagu jiro qaabka hurdada, dallacaadda iyo dallacaadda MOSFET-yadu waxay ahaanayaan kuwo isku xidhan haddii aan la ogaan batteriga ka hooseeya, markaas oo MOSFET-yadu ay goynayaan. Haddii BMS ay ogaato calaamadaha isgaadhsiinta ama qulqulka dallaca / shubista (≥2A, iyo ku dallacaadda firfircoonida, gelinta korantada jaajuurtu waa inuu ka sarreeyaa ugu yaraan 2V korantada batteriga, ama waxaa jira calaamad toosin), isla markiiba way ka jawaabi doontaa oo geli xaaladda shaqada ee toosinta.
3. Istaraatiijiyada Calibration ee SOC
Awoodda dhabta ah ee batteriga iyo xxAH waxaa lagu dejiyay kombuyuutarka martida loo yahay. Inta lagu jiro dallacaadda, marka korantada unuggu gaadho qiimaha ugu badnaan ee koronto-dhaafka ah oo uu jiro dallaco hadda, SOC waxaa lagu qiyaasi doonaa 100%. (Inta lagu jiro bixinta, khaladaadka xisaabinta SOC dartiis, SOC ma noqon karto 0% xitaa marka shuruudaha alaarmiga hooseeyo la buuxiyo. Fiiro gaar ah: Istaraatiijiyada qasabka ah ee SOC inay eber noqoto ka dib marka ilaalinta xad-dhaafka ah ee unugyada (voltage) la habeyn karo.)
4. Xeeladda Xakamaynta Khaladka
Cilladaha waxaa loo kala saaraa laba heer. BMS waxay u maareysaa heerar kala duwan oo cillado ah:
- Nivå 1: Cilladaha yaryar, BMS-ga oo keliya ayaa qaylo-dhaanta.
- Heerka 2: Cillad aad u daran, BMS alaarmiga oo gooyay furaha MOS.
Cilladaha Heerka 2 ee soo socda, beddelka MOS lama gooyo: qaylo-dhaan faraqa koronto oo xad-dhaaf ah, alaarmiga faraqa heerkulka xad-dhaafka ah, alaarmiga SOC sare, iyo alaarmiga SOC hooseeya.
5. Xakamaynta dheellitirka
Isku dheellitirnaan dadban ayaa la isticmaalaa. TheBMS waxa ay maamushaa soo daynta unugyada danabkoodu sareeyoiyada oo loo marayo resistors, oo tamarta u kala firdhisa kulayl ahaan. Isku dheelitirka hadda jira waa 30mA. Isku dheellitirnaanta waxa ay kicisaa marka dhammaan shuruudaha soo socda la buuxiyo:
- Inta lagu jiro dallacaadda;
- Korantada firfircoonida dheellitirka ayaa la gaadhay (lagu dejin karaa iyada oo loo marayo kombuyuutarka martida loo yahay); Farqiga korantada ee u dhexeeya unugyada> 50mV (50mV waa qiimaha caadiga ah, lagu dejin karo iyada oo loo marayo kumbuyuutarka martida loo yahay).
- Danab firfircoonida ugu talagalka ah ee fosfateed birta lithium: 3.2V;
- Danab firfircoonida caadiga ah ee lithium ternary: 3.8V;
- Danab firfircoonida ugu talagalka ah ee lithium titanate: 2.4V;
6. Qiyaasta SOC
BMS waxay ku qiyaastay SOC iyadoo la isticmaalayo habka tirinta coulomb, ururinta kharashka ama sii daynta si loo qiyaaso qiimaha SOC ee batteriga.
Khaladka Qiyaasta SOC:
| Saxnaanta | Xaddiga SOC |
|---|---|
| ≤ 10% | 0% < SOC < 100% |
7. Saxnaanta korantada, hadda, iyo heerkulka
| Shaqada | Saxnaanta | Unug |
|---|---|---|
| Voltage Cell | ≤ 15% | mV |
| Wadarta Voltage | ≤ 1% | V |
| Hadda | ≤ 3% FSR | A |
| Heerkulka | ≤ 2 | °C |
8. Isticmaalka Korontada
- Is-isticmaalka hadda ee guddiga qalabka marka la shaqeynayo: <500µA;
- Is-isticmaalka hadda ee guddiga software marka uu shaqeynayo: <35mA (la'aanteed isgaarsiinta dibadda: <25mA);
- Is-isticmaalka hadda ee qaabka hurdada: <800µA.
9. Furaha Furaha iyo Furaha
- Caqliga caadiga ah ee shaqada beddelka jilicsan waa caqli gal; waxaa loo habeyn karaa si macquul ah.
- Shaqada caadiga ah ee furaha furaha waa in la dhaqaajiyo BMS; hawlaha kale ee macquulka ah waa la beddeli karaa.
