1. Hababka Toosinta
Marka ugu horreysa ee la shido, waxaa jira saddex hab oo lagu toosiyo (alaabada mustaqbalka uma baahna kicinta):
- Toosinta kicinta badhanka;
- Toosinta kicinta dallacaadda;
- Badhanka Bluetooth-ka oo toosi.
Wixii ku xiga ee korontada lagu shido, waxaa jira lix hab oo toosin ah:
- Toosinta kicinta badhanka;
- Toosinta kicinta dallacaadda (marka danabka gelinta dallacaadda uu ugu yaraan 2V ka sarreeyo danabka batteriga);
- 485 kicinta isgaarsiinta;
- Toosinta dhaqdhaqaaqa isgaarsiinta ee CAN;
- Toosinta kicinta dheecaanka (hadda ≥ 2A);
- Furaha kicinta degdegga ah.
2. Habka Hurdada BMS
TheBMS-kawuxuu galaa qaab koronto yar (waqtiga caadiga ah waa 3600 ilbiriqsi) marka uusan jirin isgaarsiin, ma jiro koronto koronto/dareerin, mana jiro calaamad soo-jeedin. Inta lagu jiro habka hurdada, MOSFET-yada dallacaadda iyo kuwa dallacaadda waxay ku xirnaan doonaan ilaa laga ogaado danab hoose oo batteriga ah, markaas MOSFET-yadu way go'i doonaan. Haddii BMS ay ogaato calaamadaha isgaarsiinta ama hirarka dallacaadda/dareerinta (≥2A, iyo si loogu dallaco dallacaadda, danabka gelinta dallacaadda waa inuu ahaadaa ugu yaraan 2V ka sarreeya danabka batteriga, ama uu jiro calaamad soo-jeedin), isla markiiba way ka jawaabi doontaa oo geli doontaa xaaladda shaqada soo-jeedinta.
3. Istaraatiijiyadda Kala-hagaajinta SOC
Awoodda guud ee dhabta ah ee baytariga iyo xxAH waxaa lagu dejiyaa kombiyuutarka martida loo yahay. Inta lagu jiro dallacaadda, marka danabku uu gaaro qiimaha ugu badan ee danab xad-dhaafka ah oo uu jiro koronto dallacaadda, SOC waxaa lagu hagaajin doonaa 100%. (Inta lagu jiro dallacaadda, khaladaadka xisaabinta SOC awgeed, SOC waxaa laga yaabaa inaysan noqon 0% xitaa marka xaaladaha digniinta danab hoosaadka la buuxiyo. Fiiro gaar ah: Istaraatiijiyadda lagu qasbayo SOC inay eber noqoto ka dib ilaalinta xad-dhaafka ah ee unugga (danab hoosaadka) waa la habeyn karaa.)
4. Istaraatiijiyadda Maareynta Khaladaadka
Khaladaadka waxaa loo kala saaraa laba heer. BMS waxay si kala duwan u maareysaa heerarka kala duwan ee cilladaha:
- Heerka 1: Cilladaha yaryar, digniinaha BMS oo keliya.
- Heerka 2: Cilladaha daran, digniinaha BMS iyo jarista badhanka MOS.
Cilladaha Heerka 2aad ee soo socda, badhanka MOS lama jarayo: digniinta farqiga danabka ee xad-dhaafka ah, digniinta farqiga heerkulka ee xad-dhaafka ah, digniinta SOC oo sareysa, iyo digniinta SOC oo hooseysa.
5. Xakamaynta Dheelitirka
Isku dheelitirka dadban ayaa la isticmaalaa.BMS waxay xakameysaa sii deynta unugyada danab sare lehiyada oo loo marayo iska caabbiyeyaal, iyadoo tamarta lagu kala firdhiyo kulaylka. Korontada dheelitirka waa 30mA. Dheellitirku wuxuu bilaabmaa marka dhammaan shuruudaha soo socda la buuxiyo:
- Inta lagu jiro dallacaadda;
- Danabka firfircoonida dheelitirka ayaa la gaarayaa (lagu dejin karaa iyada oo loo marayo kombiyuutarka martida loo yahay); Farqiga danabka ee u dhexeeya unugyada > 50mV (50mV waa qiimaha caadiga ah, oo lagu dejin karo iyada oo loo marayo kombiyuutarka martida loo yahay).
- Danabka firfircoonida caadiga ah ee fosfate-ka birta lithium: 3.2V;
- Danabka firfircoonida ee caadiga ah ee lithium-ka ternary: 3.8V;
- Danabka firfircoonida ee caadiga ah ee lithium titanate: 2.4V;
6. Qiimaynta SOC
BMS waxay qiyaastaa SOC iyadoo adeegsanaysa habka tirinta coulomb, iyadoo ururinaysa dallacaadda ama sii deynta si loo qiyaaso qiimaha SOC ee baytariga.
Khaladka Qiimaynta SOC:
| Saxnaanta | Kala duwanaanshaha SOC |
|---|---|
| ≤ 10% | 0% < SOC < 100% |
7. Saxnaanta Danabka, Hadda, iyo Heerkulka
| Shaqada | Saxnaanta | Cutubka |
|---|---|---|
| Danab Unug | ≤ 15% | mV |
| Wadarta Danabka | ≤ 1% | V |
| Hadda | ≤ 3% FSR | A |
| Heerkulka | ≤ 2 | °C |
8. Isticmaalka Korontada
- Hadda isticmaalka iskiis ah ee looxa qalabka marka la shaqeynayo: < 500µA;
- Hadda isticmaalka iskiis ah ee guddiga software-ka marka la shaqeynayo: < 35mA (iyada oo aan lahayn isgaarsiin dibadeed: < 25mA);
- Hawada is-isticmaalka ee qaabka hurdada: < 800µA.
9. Beddelka Jilicsan iyo Beddelka Furaha
- Macnaha caadiga ah ee shaqada badhanka jilicsan waa maan-gal rogan; waxaa loo habeyn karaa maan-gal togan.
- Shaqada caadiga ah ee badhanka furaha waa in la hawlgeliyo BMS; hawlaha kale ee macquulka ah waa la habeyn karaa.
