Lithium bhatiri zvinhu zvine humwe hunhu hunovadzivirira kubva pakuchajiswa, pamusoro-kusunungurwa, pamusoro-ikozvino, ipfupi-inotenderera, uye inochajiswa uye inoburitswa pane yakanyanya-yepamusoro uye yakaderera tembiricha. Naizvozvo, iyo lithium bhatiri paki inogara ichiperekedzwa neyakapfava BMS. BMS inoreva iyoBattery Management Systembhatiri. Management system, inonziwo protection board.
BMS basa
(1) Maonero uye kuyerwa kuyerwa kuona mamiriro ebhatiri
Iri ndiro basa guru reBMS, kusanganisira kuyerwa uye kuverenga kwezvimwe zviratidzo zvinoratidzira, zvinosanganisira voltage, ikozvino, tembiricha, simba, SOC (state of charge), SOH (mamiriro ehutano), SOP (nyika yesimba), SOE (nyika simba).
SOC inogona kunzwisiswa kazhinji sekuti ingani simba rasara mubhatiri, uye kukosha kwayo kuri pakati pe0-100%. Iyi ndiyo inonyanya kukosha parameter muBMS; SOH inoreva mamiriro ehutano hwebhatiri (kana dhigirii rekuderera kwebhatiri), iyo ndiyo chaiyo kugona kwebhatiri razvino. Kuenzaniswa nehuwandu hwehuwandu, apo SOH yakaderera kupfuura 80%, bhatiri haigoni kushandiswa munzvimbo yemagetsi.
(2) Alarm uye dziviriro
Kana chisionekwi chikaitika mubhatiri, BMS inogona kuzivisa chikuva kuchengetedza bhatiri uye kutora matanho anoenderana. Panguva imwecheteyo, iyo isina kujairika alarm ruzivo inotumirwa kune yekutarisa uye manejimendi chikuva uye kugadzira akasiyana mazinga eruzivo rwealarm.
Semuenzaniso, kana tembiricha yanyanya kupisa, iyo BMS inobvisa zvakananga kubhadharisa uye kuburitsa dunhu, kuita kudzivirira kwekupisa, uye kutumira alarm kumashure.
Lithium mabhatiri anozonyanya kuburitsa yambiro kune zvinotevera nyaya:
Overcharge: single unit pamusoro-voltage, yakazara voltage pamusoro-voltage, kuchaja pamusoro-current;
Over-discharge: single unit pasi-voltage, yakazara voltage pasi-voltage, discharge over-current;
Tembiricha: Iyo tembiricha yebhatiri yakakwira zvakanyanya, tembiricha yepakati yakakwira zvakanyanya, tembiricha yeMOS yakanyanya kukwira, tembiricha yepakati yebhatiri yakadzikira, uye tembiricha yepakati yakadzikira;
Mamiriro: kunyudzwa mumvura, kudhumhana, inversion, nezvimwe.
(3) Kutarisira kwakadzikama
Kudiwa kwekutungamirira kwakadzikamainomuka kubva mukusawirirana mukugadzirwa kwebhatiri uye kushandiswa.
Kubva pakuona kwekugadzira, bhatiri rega rega rine hupenyu hwayo uye maitiro. Hapana mabhatiri maviri akafanana chaizvo. Pamusana pekusawirirana kwezviparadzanisa, cathodes, anodes nezvimwe zvinhu, masimba emabhatiri akasiyana haakwanisi kunyatsoenderana. Semuenzaniso, zviratidzo zvekusagadzikana kwekusiyana kwemagetsi, kupikisa kwemukati, nezvimwewo zvebheteri rimwe nerimwe rinoumba 48V / 20AH bhatiri pack rinosiyana mukati meimwe nhanho.
Kubva pamaonero ekushandisa, iyo electrochemical reaction process haigone kuenderana panguva yekuchaja uye kuburitsa bhatiri. Kunyangwe iri bhatiri paki imwe chete, bhatiri yekuchaja uye kubuda simba kuchave kwakasiyana nekuda kwekusiyana kwetembiricha uye kudhumhana madhigirii, zvichikonzera kusaenderana kwebhatiri maseru masimba.
Naizvozvo, bhatiri rinoda zvese zviri zviviri kuenzanisa uye kuenzanisa kunoshanda. Iko ndiko kuseta maviri ezvikumbaridzo zvekutanga uye kupedzisa kuenzana: semuenzaniso, muboka remabhatiri, kuenzana kunotanga apo musiyano uripo pakati pekunyanya kukosha kwesero voltage uye avhareji voltage yeboka inosvika 50mV, uye kuenzana kunopera. ku5mv.
(4) Kukurukurirana uye nzvimbo
Iyo BMS ine yakaparadzanakutaurirana module, iyo ine basa rekutumira data uye bhatiri chinzvimbo. Inogona kufambisa iyo yakakodzera data yakanzwiwa uye kuyerwa kune yekushanda manejimendi chikuva munguva chaiyo-nguva.
Nguva yekutumira: Nov-07-2023
