Lithium mabhatiri anoshandiswa zvakanyanya mumidziyo senge smartphones, mota dzemagetsi, uye masosi eSolar. Nekudaro, kubhadharisa zvisizvo kunogona kutungamira kune njodzi dzekuchengetedza kana kukuvara zvachose.
WHY uchishandisa yakakwira-voltage charger ine njodzi uyeMaitiro ebhatiri manejimendi system (BMS) inodzivirira mabhatiri emabhatiri?
Njodzi yekukurira
Bliphium mabhatiri ane chimiro chakasimba voltage. Semuyenzaniso:
.ALifepo4(Lithium iron phosphate) cell ine komitari voltage ye3.2vuye anofaniraUsambofa wakapfuura 3.65VKana yabhadharwa zvakakwana
.ALi-ion(Lithium Cobalt) Sero, zvakajairika mumadhenji, inoshanda pa3.7Vuye inofanira kugara pazasi4.2V
Uchishandisa charger neyakawandisa voltage kupfuura muganho webhatiri masimba simba rakawandisa mumasero. Izvi zvinogona kukonzeraKuwedzera,kuzvimba, kana kunyangeThermal Runaway-A ngozi yekutarisa maitiro apo bhatiri rinobata moto kana kuputika
Mashandisiro anoita BMS zuva
Iyo bhatiri manejimendi system (BMS) inoita kunge "Guardian" yeBlhium mabhatiri. Heano maitiro azvinoita:
1.Voltage Control
Iyo BMS inotaririra yega yega cell's cell. Kana iyo yepamusoro-voltage charger yakabatana, iyo BMS inowana overvoltage uyeinocheka dunhu rekuchajakudzivirira kukuvara
2.Tembiricha yekudzora
Kubhadhara nekukurumidza kana kufuratira kunopisa kupisa. Iyo BMS inoteedzera tembiricha uye inoderedza yekubhadhara kumhanya kana kumira kubhadharisa kana bhatiri rikanyanyisa kupisa113.
3.Cell balancing
Mune akawanda-cell mabhatiri (se12V kana 24V mapaketi), mamwe masero anokuvara nekukurumidza kupfuura vamwe. Iyo BSS inogovera simba kuti uve nechokwadi chekuti masero ese anosvika kune imwe chete voltage, kudzivirira kuwanda mumasero akasimba
4.Kuchengetedza Shutdown
Kana iyo BSMS yakawana nyaya dzinonetsa senge dzakanyanya kufararira kana voltage spikes, inobvisa bhatiri zvichishandisa zvikamu zvakadaiMosfets(zvemagetsi switches) kanavatauri(mechanical kudzokorora)
Nzira yekurudyi yekubhadhara lithium mabhatiri
Gara uchishandisa chargerkufananidza voltage yako yebhatiri uye chemistry.
Semuyenzaniso:
A 12V Lifepo4 bhatiri (4 masero anoteedzana) anoda charger ne14.6V Yakakura Kubuda(4 × 3.65V)
A 7.4V Li-Ion Pack (2 masero) anoda8.4V charger
Kunyangwe kana bMS iripo, uchishandisa chisingapindirani charger chinosimbisa hurongwa. Ipo maBMS anogona kupindira, akadzokororwazve kuratidzwa kunogona kunetesa zvikamu zvaro nekufamba kwenguva
Mhedziso
Bliphium mabhatiri ane simba asi akaomesesa. AYakakwira-mhando BMSinokosha kuti uve nechokwadi chekuchengeteka, kushanda zvakanaka, uye hurefu. Kunyange zvichikwanisa kuchengetedza kwenguva pfupi kubva kune yakakwira-voltage charger, kuvimba neiyi ine njodzi. Gara uchishandisa iyo chaiyo charger-yako bhatiri (uye kuchengeteka) kuchakutenda!
Rangarira: BMS yakafanana nechigaro chechigaro. Imomo racho kuti akuponese mune emergency, asi haufanirwe kuyedza miganhu yayo!
