1. Iindlela zokuvuka

Xa kulayitiwe okokuqala, kukho iindlela ezintathu zokuvuka (iimveliso zexesha elizayo aziyi kufuna zisebenze):

  1. Ukuvuka kweqhosha kusebenze;
  2. Ukutshaja ukuvuswa kokuvula;
  3. Ukuvuka kweqhosha leBluetooth.

Ukuvula amandla alandelayo, kukho iindlela ezintandathu zokuvuka:

  1. Ukuvuka kweqhosha kusebenze;
  2. Ukutshaja ukuvuswa kokuvuka (xa igalelo lombane wetshaja ubuncinane yi-2V ephezulu kunombane webhetri);
  3. 485 ukuvuswa konxibelelwano;
  4. I-CAN ivuse unxibelelwano;
  5. Ukukhutshwa kokuvuswa kokuvuswa (okwangoku ≥ 2A);
  6. 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. IQhinga lokuPhatha iFault

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:

  1. Ngexesha lokutshaja;
  2. 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.
