1. Izindlela zokuvuka
Uma uqala unikwa amandla, kunezindlela ezintathu zokuvuka (imikhiqizo yesikhathi esizayo ngeke idinge ukwenza kusebenze):
- Inkinobho activation ukuvuka;
- Ukushaja kusebenze ukuvuka;
- Inkinobho ye-Bluetooth Vuka.
Okwenziwa amandla alandelayo, kunezindlela eziyisithupha zokuvuka:
- Inkinobho activation ukuvuka;
- Ukushaja kusebenze ukuvuka phezulu (lapho i-voltage yokufaka ishaja okungenani i-2v ephakeme kune-voltage yebhethri);
- Ukusebenza kwezokuxhumana okungu-485 Ukuvuka;
- Ingabe isebenze ukuxhumana kusebenze;
- Ukulahlwa kusebenze ukuvuka-up (≥ 2a);
- Kusebenze okusemqoka ukuvuka.
2. Imodi yokulala ye-BMS
Le khasiI-BMSIngena kwimodi yamandla aphansi (isikhathi esizenzakalelayo yimizuzwana engama-3600) lapho kungekho ukuxhumana, akukho mali ekhokhiswayo, futhi akukho signali-up. Ngemodi yokulala, ukushaja kanye nokukhipha ama-Mosfets kuhlala kuxhunyiwe ngaphandle kokuthi kutholakale ibhethri elingaphansi kwebhethri, lapho ama-Mosfets azonqamula. Uma i-BMS ithola amasiginali okuxhumana noma amacala okukhokhisa / ama-≥2a, kanye nokushaja i-activation, i-voltage yokufaka ishaja kumele okungenani ibe ngu-2v ngaphezulu kwe-voltage, noma kunesiginali yokuvuka), izophendula ngokushesha futhi ingene ekusebenzeni okusebenzayo.
3. Icebo le-SOC Calibration Strategy
Umthamo wangempela webhethri futhi i-xxah isethwe ngekhompyutha yomgcini. Ngesikhathi sokushaja, lapho i-cell voltage ifinyelela inani eliphakeme kakhulu le-overvoltage futhi kukhona ukushaja okwamanje, i-SOC izokwenziwa i-100%. (Ngesikhathi sokudilizwa, ngenxa ye-SOC Amaphutha wokubala, i-SOC kungenzeka kungabi ngu-0% noma ngabe kuhlangatshezwane nezimo ze-alamu ezingaphansi. Qaphela: Icebo lokuphoqelela i-SoCro ngemuva kokuvikelwa kwe-cell (ngaphansi kwe-undervoltage) kungenziwa ngokwezifiso.)
4. Isu lokuphatha iphutha
Amaphutha ahlukaniswa ngamazinga amabili. I-BMS iphatha amazinga ahlukene amaphutha ngendlela ehlukile:
- Ileveli 1: Amaphutha amancane, ama-arms we-BMS kuphela.
- Ileveli 2: Amaphutha abuhlungu, ama-alamu we-BMS bese usika i-mos switch.
Kula maphutha alandelayo ama-2, i-Mos switch ayinqunyelwe: I-alamu yemikhuba eminingi ye-voltage umehluko, i-alamu yokulinganisa ngokweqile, i-alamu ephezulu, ne-alamu ephansi.
I-5. Ukulawula Ukulinganisa
Kusetshenziswa ukulinganisa. Le khasiI-BMS ilawula ukuphuma kwamaseli aphezulu we-voltageNgaphezulu kokumelana, ukuqeda amandla njengokushisa. Ukulinganisa kwamanje kungu-30mA. Ukulinganisa kubangelwa lapho zonke izimo ezilandelayo zihlangatshezwa:
- Ngesikhathi sokushaja;
- I-Balancing activation Vertage ifinyelelwa (ichitheke ngekhompyutha yomgcini); Umehluko weVoltage phakathi kwamaseli> I-50MV (50MV yinani elizenzakalelayo, lihlala ngekhompyutha elisingathwa).
- I-voltage esebenzayo esebenzayo ye-Lithium Iron phosphate: 3.2V;
- I-Volfage Ezenzakalelayo Ye-activation ye-ternary Lithium: 3.8V;
- I-Volfage Ezenzakalelayo Yokusebenza Kwe-Lithium Titanate: 2.4V;
6. Isilinganiso se-SOC
I-BMS ilinganisa i-SoC isebenzisa indlela yokubala ye-coulomm, iqoqa icala noma lokulahlwa ukulinganisa inani le-SOC yebhethri.
Iphutha Lokulinganisa Kwe-SOC:
| Ukuqonda nqo | I-SOC HANNAR |
|---|---|
| ≤ 10% | 0% <soci <100% |
7
| Sebenza | Ukuqonda nqo | Umuvo |
|---|---|---|
| I-Cell Voltage | ≤ 15% | mV |
| Inani eliphelele | ≤ 1% | V |
| -Dlulayo | ≤ 3% FSR | A |
| Izinga lokushisa nokubanda | ≤ 2 | ° C |
8. Ukusetshenziswa kwamandla
- Ukuzisebenzisa kwamanje kwebhodi le-Hardware lapho usebenza: <500μa;
- Ukuzisebenzisa kwamanje kwebhodi lesoftware lapho usebenza: <35MA (ngaphandle kokuxhumana kwangaphandle: <25ma);
- Ukuzijwayeza kwamanje kwimodi yokulala: <800μa.
9
- I-Logic Ezenzakalelayo yomsebenzi wokushintsha okuthambile ngumbono we-inverse; Kungenziwa ngokwezifiso ku-logic enhle.
- Umsebenzi ozenzakalelayo we-Key Shintsha ukwenza kusebenze i-BMS; Eminye imisebenzi enengqondo ingenziwa ngokwezifiso.
