Parizvino, mabhatiri e-lithium ari kuwedzera uye anoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yedhijitari yakadai semabhuku ekunyorera, makamera edhijitari, uye makamera evhidhiyo edhijitari. Pamusoro pezvo, ivo zvakare vane tarisiro yakakura mumotokari, nharembozha nhepfenyuro, uye magetsi ekuchengetedza magetsi. Muchiitiko ichi, kushandiswa kwemabhatiri hakuchaoneki ega semunharembozha, asi zvakanyanya muchimiro chenhevedzano kana parallel bhatiri packs.
Kugona uye hupenyu hwebhatiri pack hazvisi chete zvine chekuita nebhatiri rimwe nerimwe, asi zvakare zvine chekuita nekusagadzikana pakati pebhatiri rega rega. Kusasimba kunoenderana kunokwevera zvakanyanya pasi kushanda kwebhatiri pack. Kusagadzikana kwekuzvisunungura chikamu chakakosha chezvinhu zvinofurira. Bhatiri ine isingawirirani yekuzviburitsa ichave nemusiyano wakakura muSOC mushure menguva yekuchengetedza, izvo zvichakanganisa zvakanyanya kugona kwayo uye kuchengeteka.
Sei kuzvisunungura kuchiitika?
Kana bhatiri yakazaruka, mhinduro iri pamusoro haiitike, asi simba richaramba richiderera, iro rinonyanya kukonzerwa nekuzvibvisa kwebhatiri. Zvikonzero zvikuru zvekuzvibvisa pachako ndezvi:
a. Internal leakage erekitironi kunokonzerwa nemunharaunda maerekitironi conduction of electrolyte kana mamwe mukati mapfupi maseketi.
b. Kubuda kwemagetsi ekunze nekuda kwekushomeka kwemabhatiri zvisimbiso kana gaskets kana kusakwana kwekudzivirira pakati pemagomba ekutungamirira ekunze (makondakita ekunze, humidity).
c. Electrode/electrolyte reactions, sekuora kweanode kana kuderedzwa kwecathode nekuda kwe electrolyte, kusvibiswa.
d. Kuparara kwechikamu che electrode inoshanda zvinhu.
e. Passivation ye electrodes nekuda kwekuora zvigadzirwa (insolubles uye adsorbed magasi).
f. Iyo electrode inopfekwa nemagetsi kana kushorwa pakati pe electrode uye muunganidzi wezvino inova yakakura.
Kufurira kuzvibvisa
Kuzvibvisa pachako kunotungamirira kukudonha kwesimba panguva yekuchengetedza.Matambudziko mazhinji akajairika anokonzerwa nekunyanyisa kuzvibvisa:
1. Motokari yakamira kwenguva yakareba uye haigoni kumutswa;
2. Bhatiri risati raiswa mukuchengetedza, mhepo uye zvimwe zvinhu zvakajairika, uye inowanikwa kuti mhepo yakaderera kana kunyange zero painotumirwa;
3. Muzhizha, kana GPS yemotokari yakaiswa pamotokari, simba kana nguva yekushandisa ichave isina kukwana zvakakwana mushure mechinguva, kunyange nebhatiri rinoputika.
Kuzviburitsa wega kunotungamira kuwedzera SOC misiyano pakati pemabhatiri uye kuderedzwa kwebhatiri paki
Pamusana pekusagadzikana kwekuzvibvisa kwebhatiri, SOC yebhatiri mubhatiri pack ichave yakasiyana mushure mekuchengetedza, uye kushanda kwebheteri kuchaderera. Vatengi vanogona kazhinji kuwana dambudziko rekuderera kwekuita mushure mekugamuchira bhatiri paki yakachengetwa kwenguva yakati. Kana mutsauko weSOC uchisvika pa20%, huwandu hwebhatiri yakasanganiswa inongova 60% ~ 70%.
Nzira yekugadzirisa sei dambudziko rekusiyana kukuru kweSOC kunokonzerwa nekuzvisunungura?
Zviri nyore, Isu tinongoda kuenzanisa simba rebhatiri uye kuendesa simba repamusoro-voltage sero kune yakaderera-voltage sero. Parizvino pane nzira mbiri: passive balancing uye inoshanda kuenzanisa
Passive kuenzana ndeyekubatanidza kuenzanisa kwekudzivirira mukufanana kune yega bhatiri sero. Kana sero richinge rasvika pakuwedzeredza kumberi, bhatiri rinogona kuramba richichajwa uye kuchaja mamwe mabhatiri ane low-voltage. Kubudirira kweiyi nzira yekuenzanisa haisi yakakwirira, uye simba rakarasika rinorasika nenzira yekupisa. Iko kuenzana kunofanirwa kuitwa mune yekuchaja modhi, uye yakaenzana ikozvino inowanzoita 30mA kusvika 100mA.
Active equalizerkazhinji anoenzanisa bhatiri nekufambisa simba uye kuendesa simba remaseru ane yakawandisa voltage kune mamwe maseru ane low voltage. Iyi nzira yekuenzanisa ine hunyanzvi hwepamusoro uye inogona kuenzana mune zvese kuchaja uye kuburitsa nyika. Kuenzana kwayo kwazvino kwakakura kakawanda kupfuura kuenzana kwazvino, kazhinji pakati pe1A-10A.
