1. Iindlela zokuvuka
Xa kulayitiwe okokuqala, kukho iindlela ezintathu zokuvuka (iimveliso zexesha elizayo aziyi kufuna zisebenze):
- Ukuvuka kweqhosha kusebenze;
- Ukutshaja ukuvuswa kokuvula;
- Ukuvuka kweqhosha leBluetooth.
Ukuvula amandla alandelayo, kukho iindlela ezintandathu zokuvuka:
- Ukuvuka kweqhosha kusebenze;
- Ukutshaja ukuvuswa kokuvuka (xa igalelo lombane wetshaja ubuncinane yi-2V ephezulu kunombane webhetri);
- 485 ukuvuswa konxibelelwano;
- I-CAN ivuse unxibelelwano;
- Ukukhutshwa kokuvuswa kokuvuswa (okwangoku ≥ 2A);
- Ukuvusa okungundoqo.
2. Imo yokuLala ye-BMS
IBMSingena kwimowudi yamandla aphantsi (ixesha elimiselweyo yimizuzwana engama-3600) xa kungekho nxibelelwano, akukho ntlawulo/ukukhutshwa kwangoku, kwaye akukho signali yokuvuka. Ngexesha lemo yokulala, ukutshaja kunye nokukhupha ii-MOSFET zihlala ziqhagamshelwe ngaphandle kokuba kuchongiwe ukuba ibhetri ingaphantsi kombane, ngelo xesha ii-MOSFET ziya kuqhawuka. Ukuba i-BMS ibona iimpawu zonxibelelwano okanye ukutshaja/ukukhupha imisinga (≥2A, kunye nokuvula ukutshaja, amandla ombane okufaka itshaja kufuneka ubuncinane abe yi-2V ephezulu kunombane webhetri, okanye kukho isignali yokuvuka), iya kuphendula ngoko nangoko kwaye ngena kwimo yokusebenza yokuvuka.
3. ISicwangciso soQuquzelo seSOC
Umthamo opheleleyo webhetri kunye ne-xxAH zisetwe kwikhompyuter yokusingatha. Ngethuba lokutshaja, xa i-voltage yeseli ifikelela kwixabiso eliphezulu lokugqithiswa kwe-overvoltage kwaye kukho ukutshaja okwangoku, i-SOC iya kulinganiswa kwi-100%. (Ngexesha lokukhutshwa, ngenxa yeempazamo zokubala ze-SOC, i-SOC ayinakuba yi-0% nangona iimeko ze-alamu eziphantsi kombane zihlangatyezwana nazo. Qaphela: Isicwangciso sokunyanzelisa i-SOC kwi-zero emva kokukhuselwa kwe-cell overdischarge (undervoltage) ingenziwa ngokwezifiso.)
4. ISicwangciso-qhinga sokuPhathwa kweePhoso
Iimpazamo zihlelwa ngamanqanaba amabini. I-BMS iphatha amanqanaba ahlukeneyo eziphoso ngokwahlukileyo:
- Inqanaba loku-1: Iimpazamo ezincinci, i-BMS ilumkisa kuphela.
- Inqanaba lesi-2: Iimpazamo ezinzulu, i-alamu ye-BMS kwaye inqumle i-MOS switch.
Kwezi mpazamo zilandelayo zeNqanaba lesi-2, iswitshi ye-MOS ayinqunyulwanga: i-alam yokwahlukana kwamandla ombane amaninzi, i-alam yokwahlukana kobushushu obugqithisileyo, i-alamu ephezulu ye-SOC, kunye ne-alarm ye-SOC ephantsi.
5. Ukulawula ukulinganisa
Kusetyenziswa iPasisive balancing. II-BMS ilawula ukukhutshwa kweeseli zamandla aphezulungokusebenzisa izixhasi, ukukhupha amandla njengobushushu. I-balance current yi-30mA. Ulungelelwaniso luqalwa xa yonke le miqathango ilandelayo ihlangatyezwane:
- Ngexesha lokutshaja;
- I-voltage yokuvula i-bancing ifikelelwe (isetyenzisiwe ngekhompyutha yokusingatha); Umahluko wamandla ombane phakathi kweeseli> 50mV (50mV lixabiso elingagqibekanga, elinokusetwa ngekhompyuter yenginginya).
- Amandla ombane wokuvula i-lithium iron phosphate: 3.2V;
- I-voltage yokuvula i-default ye-ternary lithium: 3.8V;
- I-voltage esebenzayo yokuvula i-lithium titanate: 2.4V;
6. Uqikelelo lweSOC
I-BMS iqikelela i-SOC isebenzisa indlela yokubala i-coulomb, iqokelela intlawulo okanye ukukhupha ukuqikelela ixabiso lebhetri le-SOC.
Imposiso yoqikelelo lwe-SOC:
| Ukuchaneka | Uluhlu lwe-SOC |
|---|---|
| ≤ 10% | 0% < SOC < 100% |
7. Ukuchaneka kombane, ngoku, kunye nokuchaneka kobushushu
| Umsebenzi | Ukuchaneka | Iyunithi |
|---|---|---|
| Umbane weSeli | ≤ 15% | mV |
| Umbane opheleleyo | ≤ 1% | V |
| Okwangoku | ≤ 3%FSR | A |
| Ubushushu | ≤ 2 | °C |
8. Ukusetyenziswa kwamandla
- Ukuzisebenzisela ngoku kwibhodi yehardware xa usebenza: <500µA;
- I-self-consumption current yebhodi yesoftware xa usebenza: <35mA (ngaphandle konxibelelwano lwangaphandle: <25mA);
- Ukuzityela ngoku kwimo yokulala: <800µA.
9. Ukutshintsha okuthambileyo kunye noTshintsho olungundoqo
- Ingqiqo engagqibekanga yomsebenzi wokutshintsha okuthambileyo yingqiqo eguqukileyo; ingenziwa ngokwezifiso ukuya kwingqiqo eyakhayo.
- Umsebenzi omiselweyo wesitshixo sesitshixo kukwenza iBMS isebenze; eminye imisebenzi yengqiqo inokwenziwa.
