1.Chii chinonzi BMS Battery Management System?
Iyo BMS Battery Management System inonyanya kushandiswa kune hungwaru manejimendi uye kugadzirisa mabhatiri mayuniti, kudzivirira kuwandisa uye kudhaya-kuburitsa mabhatiri, kuwedzera hupenyu hwebhatiri, uye kuongorora mamiriro ebhatiri.
2.Zvikamu zveBMS
Iyo BMS inonyanya kuumbwa neBMU master controller, CSC sub-controller, CSU balancing module, HVU high-voltage controller, BTU bhatiri chimiro chechiratidzo unit, uye GPS yekutaurirana module.
3.Life cycle fomu yeBMS
BhatiriManagement System (BMS) chinhu chakakosha chemotokari dzemagetsi uye mamwe mabhatiri maapplication. Iyo ine basa rekutarisa nekudzora mamiriro ebhatiri kuti ive nechokwadi chekuchengetedza uye kushanda zvakanaka. Hupenyu hwe aBMSinogona kukamurwa kuita matanho akati wandei:
- Dhizaini nhanho: Munguva yeBMS dhizaini nhanho, basa reBMS uye kumisikidzwa kunofanirwa kutariswa zvichibva pazvinhu zvakaita serudzi rwebhatiri, mamiriro ekushandisa, uyekuita zvinodiwa. Iyi nhanho inoda tsvakiridzo yakakura uye kuyedzwa kuti ive nechokwadi chekutiBMS dhizainiinosangana nezvinodiwa zvebhatiri application.
- Kugadzira nhanho: Munguva yeBMS yekugadzira nhanho, izvo zvakasiyana zvikamu zveBMS zvinofanirwa kugadzirwa zvinoenderana nedhizaini zvinodiwa uye kuunganidzwa nekuedzwa. Iyi nhanho inoda kusimba kwehutongi hwemhando kuti ive nechokwadi chekuti mhando nekuita kweBMS zvinosangana nezvinodiwa zvekugadzira.
- Kuisa uye kugadzirisa nhanho: Panguva yeKuiswa kweBMSuyedebugging stage, BMS inofanira kuiswa mubhatiri system uye yakaedzwa uye yakagadziriswa. Iyi nhanho inoda kutarisisa kukuru uye kurongeka kuti ive nechokwadi chekuti kuisirwa nekugadzirisa kweBMS hakukuvadze bhatiri kana kukanganisa kuita kwayo.
- Kushanda nekugadzirisa nhanho: Munguva yeBMS yekushanda nekugadzirisa nhanho, nguva dzose cheki uye kugadzirisa kunofanirwa kuitwa kuti ive nechokwadi chekushanda kwakajairika uye kuita kweBMS. Iyi nhanho inoda kurekodha uye ongororo yedata kuti ikurumidze kuona nekugadzirisa matambudziko uye kusimudzira nekuchengetedza iyo BMS.
- Retirementuyerenewal stage: Panguva yeBMS yekurega basa uye nhanho yekuvandudza, BMS inofanirwa kuvandudzwa kana kutsiviwa zvichienderana nehupenyu hwebhatiri uye nekuita zvinodiwa. Danho iri rinodadata analysisuye ongororo yekuona kana BMS ichida kuvandudzwa kana kutsiviwa uye nekuvandudza kana kutsiva BMS.
4.Core software mabasa eBMS
Kuyera basa
(1) Yekutanga ruzivo kuyerwa: yekutarisa bhatiri voltage, yazvino chiratidzo, uye bhatiri paki tembiricha. Basa rakanyanya kukosha reiyo bhatiri manejimendi system ndeyekuyera voltage, ikozvino, uye tembiricha yemasero ebhatiri, inova hwaro hwese epamusoro-chikamu kuverenga uye kutonga mantiki yebhatiri manejimendi system.
(2) Insulation kuramba yekuona: Iyo yese bhatiri system uye yakakwira-voltage system inoda kuedzwa kuti ivharwe nebhatiri manejimendi system.
(3) High-voltage interlock monitor (HVIL): inoshandiswa kusimbisa kutendeseka kwese high-voltage system. Kana kutendeseka kwe-high-voltage system circuit kwakakuvadzwa, matanho ekuchengetedza anoshandiswa.
Estimation function
(1) SOC uye SOH fungidziro: iyo yakakosha uye yakanyanya kuoma chikamu
(2) Kuyera: gadzirisa iyo SOC x kugona kusaenzana pakati pemamonomers kuburikidza nekuenzanisa dunhu.
(3) Battery simba kudzikamisa: iyo yekupinza uye yekubuda simba yebhatiri inogumira pane dzakasiyana tembiricha dzeSOC.
Mamwe mabasa
(1) Relay control: inosanganisira main +, main-, kuchaja relay +, kuchaja relay -, pre-charging relay
(2) Kudzora kupisa
(3) Kukurukurirana basa
(4) Kukanganisa kuongororwa uye alarm
(5) Kutadza-kushivirira kushanda
