Wakambozvibvunza here kuti sei aBMSinogona kuona ikozvino ye lithium bhatiri pack? Pane multimeter yakavakirwa mairi?
Chekutanga, kune marudzi maviri eBattery Management Systems (BMS): smart uye hardware shanduro. Chete smart BMS inokwanisa kufambisa ruzivo rwazvino, nepo vhezheni yehardware haina.
A BMS kazhinji ine yekudzora yakabatanidzwa dunhu (IC), MOSFET switch, ikozvino yekutarisa maseketi, uye tembiricha yekutarisa maseketi. Chinhu chakakosha cheiyo smart vhezheni ndiyo inodzora IC, iyo inoshanda sehuropi hwekudzivirira system. Iyo ine basa rekutarisa-nguva chaiyo yebhatiri ikozvino. Nekubatanidza neyezvino yekutarisa dunhu, iyo control IC inogona kunyatso kuwana ruzivo nezve bhatiri iripo. Kana iyo yazvino ichipfuura preset kuchengetedza miganho, iyo yekutonga IC inokurumidza kuita mutongo uye inokonzeresa zviito zvekudzivirira.
Saka, ikozvino inowanikwa sei?
Kazhinji, iyo Hall effect sensor inoshandiswa kutarisa ikozvino. Iyi sensor inoshandisa hukama pakati pemagineti minda uye yazvino. Kana ikozvino ichifamba, magnetic field inogadzirwa yakakomberedza sensor. Iyo sensor inoburitsa inoenderana voltage siginecha zvichienderana nesimba reiyo magineti. Kana iyo IC yekudzora yagamuchira iyi voltage chiratidzo, inoverengera saizi chaiyo iripo uchishandisa algorithms emukati.
Kana yazvino ikadarika kukosha kwekuchengetedza preset, senge overcurrent kana pfupi-circuit ikozvino, iyo IC yekudzora ichakurumidza kudzora MOSFET switch kuti icheke nzira iripo, ichidzivirira zvese bhatiri uye yese yedunhu system.
Pamusoro pezvo, iyo BMS inogona kushandisa zvimwe zvinopikisa uye zvimwe zvikamu kubatsira mukutarisisa kwazvino. Nekuyera kudonha kwevoltage pane resistor, saizi iripo inogona kuverengerwa.
Iyi nhevedzano yeakaomesesa uye akajeka edunhu madhizaini uye ekudzora masisitimu ese ane chinangwa chekutarisa bhatiri ikozvino uchidzivirira kubva kune overcurrent mamiriro. Ivo vanoita basa rakakosha mukuona kushandiswa kwakachengeteka kwemabhatiri e-lithium, kuwedzera hupenyu hwebhatiri, uye kuwedzera kuvimbika kweiyo yese bhatiri system, kunyanya muLiFePO4 maapplication uye mamwe maBMS akatevedzana masisitimu.
