Lithium mabhatiri anoshandiswa zvakanyanya mumidziyo yakaita sema smartphones, mota dzemagetsi, uye solar simba system. Nekudaro, kuvabhadharisa zvisizvo kunogona kutungamira kune njodzi dzekuchengetedza kana kukuvara zvachose.
Why kushandisa charger yepamusoro-voltage kune njodzi uyeiyo Battery Management System (BMS) inodzivirira sei lithium mabhatiri?
Ngozi Yekuwedzeresa
Lithium mabhatiri ane yakasimba voltage limits. Semuyenzaniso:
.ALiFePO4(Lithium Iron Phosphate) sero rine simba rezita re3.2Vuye anofanirahaimbopfuuri 3.65Vkana yazara
.ALi-ion(Lithium Cobalt) sero, inowanikwa mumafoni, inoshanda pa3.7Vuye inofanira kugara pasi4.2V
Kushandisa charger ine voltage yakakwira kupfuura inogumira bhatiri kunomanikidza simba rakawandisa mumaseru. Izvi zvinogona kukonzerakupisa kwakanyanya,kuzvimba, kana kunyangethermal runaway-Kuitika kweketani ine ngozi uko bhatiri rinobata moto kana kuputika
Maitiro eBMS Inochengetedza Zuva
Battery Management System (BMS) inoita se "muchengeti" wemabhatiri e lithium. Heino mashandiro ayo:
1.Voltage Control
Iyo BMS inotarisisa magetsi esero rega rega. Kana yakakwira-voltage charger yakabatana, BMS inoona overvoltage uyeinodimbura dunhu rekuchajakudzivirira kukanganisa
2.Tembiricha Regulation
Kuchaja nekukurumidza kana kuwandisa kunounza kupisa. Iyo BMS inoteedzera tembiricha uye inoderedza kumhanya kwekuchaja kana kumira kuchaja kana bhatiri rikapisa zvakanyanya113.
3.Cell Bancing
Mune akawanda-sero mabhatiri (se12V kana 24V mapaketi), mamwe maseru anochaja nekukurumidza kupfuura mamwe. Iyo BMS inogoverazve simba kuti ive nechokwadi chekuti masero ese anosvika kune imwechete voltage, kudzivirira kuwandisa mumasero akasimba
4.Safety Shutdown
Kana iyo BMS ikaona nyaya dzakakomba senge kunyanyisa kupisa kana voltage spikes, inobvisa bhatiri zvachose uchishandisa zvinhu zvakaita se.MOSFETs(magetsi switch) kanacontactors(mechanical relays)
Iyo Yakarurama Nzira Yekuchaja Lithium Mabhatiri
Gara uchishandisa chargerkuenzanisa voltage yebhatiri rako uye chemistry.
Semuyenzaniso:
Bhatiri re12V LiFePO4 (masero mana akatevedzana) inoda charger ine14.6V yakanyanya kubuda(4 × 3.65V)
A 7.4V Li-ion pack (2 masero) inoda8.4V charger
Kunyangwe kana BMS iripo, kushandisa charger isingaenderane kunosimbisa sisitimu. Nepo BMS ichigona kupindira, kudzokororwa overvoltage exposure inogona kuderedza zvikamu zvayo nekufamba kwenguva
Mhedziso
Lithium mabhatiri ane simba asi akapfava. Ayemhando yepamusoro BMSzvakakosha kuti uve nechokwadi chekuchengetedzwa, kushanda zvakanaka, uye hupenyu hurefu. Kunyange ichikwanisa kuchengetedza kwenguva pfupi kubva kune yakakwira-voltage charger, kuvimba neizvi kune njodzi. Gara uchishandisa charger chaiyo — bhatiri rako (nechengetedzo) zvichakutenda!
Rangarira: BMS yakafanana nebhandi repachigaro. Iripo kuti ikuponese munguva dzekukurumidzira, asi haufanirwe kuyedza miganhu yayo!
