1. Uburyo bwo gukanguka
Iyo ukoresheje bwa mbere, hari uburyo butatu bwo gukanguka (ibicuruzwa bizaza ntibisaba gukora):
- Gukangura buto gukanguka;
- Kwishyuza ibikorwa kubyuka;
- Akabuto ka Bluetooth gukanguka.
Kubububasha bukurikiraho, hariho uburyo butandatu bwo gukanguka:
- Gukangura buto gukanguka;
- Kwishyuza kwishyuza kubyuka (mugihe amashanyarazi yinjiza byibuze byibuze 2V kurenza ingufu za bateri);
- 485 itumanaho ryitumanaho kubyuka;
- URASHOBORA gutangiza itumanaho kubyuka;
- Gusohora ibikorwa byo gukanguka kubyuka (ubungubu ≥ 2A);
- Gukangura urufunguzo.
2. BMS Uburyo bwo Gusinzira
UwitekaBMSyinjira muburyo buke-imbaraga (igihe gisanzwe ni amasegonda 3600) mugihe nta tumanaho, nta kwishyuza / gusohora amashanyarazi, kandi nta kimenyetso cyo gukanguka. Mugihe cyo gusinzira, kwishyuza no gusohora MOSFETs bikomeza guhuzwa keretse iyo bateri ya bateri itabonetse, icyo gihe MOSFETs izahagarara. Niba BMS itahuye ibimenyetso byitumanaho cyangwa kwishyuza / gusohora amashanyarazi (≥2A, no mugukoresha amashanyarazi, voltage yinjira igomba kuba byibuze 2V hejuru ya voltage ya bateri, cyangwa hari ikimenyetso cyo kubyuka), izahita isubiza kandi andika leta ikangura.
3. Ingamba zo Guhindura SOC
Ubushobozi bwuzuye bwa bateri na xxAH bushyirwa muri mudasobwa yakira. Mugihe cyo kwishyuza, iyo voltage ya selile igeze kumurongo ntarengwa wa voltage kandi hariho amashanyarazi, SOC izahinduka kugeza 100%. .
4. Ingamba zo Gukemura Amakosa
Amakosa yashyizwe mubice bibiri. BMS ikemura urwego rutandukanye rw'amakosa:
- Urwego 1: Amakosa mato, BMS itabaza gusa.
- Urwego rwa 2: Amakosa akomeye, gutabaza kwa BMS no guca kuri MOS.
Ku makosa yo mu rwego rwa 2 akurikira, MOS yahinduwe ntabwo yaciwe: impuruza irenze urugero itandukanyirizo, impuruza yubushyuhe bukabije, impuruza ndende ya SOC, hamwe nimpuruza ya SOC.
5. Kugenzura Kuringaniza
Kuringaniza gusa. UwitekaBMS igenzura isohoka rya selile zo hejurubinyuze mumurwanya, gukwirakwiza ingufu nkubushyuhe. Impuzandengo iringaniye ni 30mA. Kuringaniza biterwa iyo ibisabwa byose bikurikira:
- Mugihe cyo kwishyuza;
- Kuringaniza ibikorwa bya voltage bigerwaho (bikemurwa hakoreshejwe mudasobwa yakiriye); Itandukaniro rya voltage hagati ya selile> 50mV (50mV nigiciro gisanzwe, gikemurwa hakoreshejwe mudasobwa yakiriye).
- Ubusanzwe imbaraga za voltage ya lithium fer fosifate: 3.2V;
- Ubusanzwe ibikorwa bya voltage ya lithium ya ternary: 3.8V;
- Default ya voltage ya lithium titanate: 2.4V;
6. Ikigereranyo cya SOC
BMS igereranya SOC ikoresheje uburyo bwo kubara coulomb, gukusanya amafaranga cyangwa gusohora kugirango igereranye agaciro ka bateri ya SOC.
Ikosa rya SOC Ikigereranyo:
| Ukuri | Urwego rwa SOC |
|---|---|
| ≤ 10% | 0% <SOC <100% |
7. Umuvuduko, Ibiriho, na Ubushyuhe Bwuzuye
| Imikorere | Ukuri | Igice |
|---|---|---|
| Umuvuduko w'akagari | ≤ 15% | mV |
| Umuvuduko wose | ≤ 1% | V |
| Ibiriho | ≤ 3% FSR | A |
| Ubushyuhe | ≤ 2 | ° C. |
8. Gukoresha ingufu
- Kwikoresha-wenyine wibikoresho byibyuma mugihe ukora: <500µA;
- Kwikoresha-kwifashisha ikibaho cya software mugihe ukora: <35mA (nta itumanaho ryo hanze: <25mA);
- Kwikoresha wenyine muburyo bwo gusinzira: <800µA.
9. Guhindura byoroshye no guhinduranya urufunguzo
- Mburabuzi logique kubikorwa byoroshye byahinduwe ni logique ihinduka; irashobora guhindurwa kuri logique nziza.
- Igikorwa gisanzwe cyurufunguzo ni ugukora BMS; indi mikorere yumvikana irashobora gutegurwa.
