Pakalipano, mabatire a lithiamu amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana za digito monga zolemba, makamera a digito, ndi makamera avidiyo a digito. Kuphatikiza apo, alinso ndi chiyembekezo chokulirapo pamagalimoto, masiteshoni am'manja, komanso malo opangira magetsi. Pachifukwa ichi, kugwiritsa ntchito mabatire sikuwonekeranso kokha ngati mafoni a m'manja, koma zambiri monga mndandanda kapena mapaketi a batri ofanana.
Mphamvu ndi moyo wa batire paketi sizingogwirizana ndi batire iliyonse, komanso zimagwirizana ndi kusasinthika pakati pa batire iliyonse. Kusasunthika kosasinthika kumachepetsa kwambiri magwiridwe antchito a paketi ya batri. Kukhazikika kwa kudziletsa ndi gawo lofunikira la zinthu zomwe zimakhudza. Batire yokhala ndi kudziletsa kosagwirizana idzakhala ndi kusiyana kwakukulu mu SOC pambuyo pa nthawi yosungirako, zomwe zidzakhudza kwambiri mphamvu zake ndi chitetezo.
Chifukwa chiyani kudziletsa kumachitika?
Battery ikatsegulidwa, zomwe zili pamwambapa sizichitika, koma mphamvu idzacheperachepera, yomwe makamaka imayambitsidwa ndi kudziletsa kwa batri. Zifukwa zazikulu zodzichotsera nokha ndi:
a. Kutayikira kwa ma elekitironi amkati chifukwa cha ma elekitironi am'deralo a electrolyte kapena mabwalo ena amkatikati.
b. Kutuluka kwamagetsi akunja chifukwa cha kutsekeka kosakwanira kwa zisindikizo za batri kapena ma gaskets kapena kusakwanira kokwanira pakati pa zipolopolo zotsogola zakunja (makonda akunja, chinyezi).
c. Electrode/electrolyte reactions, monga dzimbiri la anode kapena kuchepetsa cathode chifukwa cha electrolyte, zonyansa.
d. Kuwonongeka pang'ono kwa ma elekitirodi yogwira.
e. Kupititsa patsogolo ma elekitirodi chifukwa cha kuwonongeka kwa zinthu (insolubles ndi mpweya wa adsorbed).
f. Elekitirodi imavalidwa mwamakina kapena kukana pakati pa ma elekitirodi ndi wokhometsa wapano kumakhala kokulirapo.
Chikoka cha kudziletsa
Kudziletsa kumabweretsa kuchepa kwa mphamvu panthawi yosungira.Mavuto ambiri omwe amayamba chifukwa cha kudziletsa kwambiri:
1. Galimoto yayimitsidwa kwa nthawi yayitali kwambiri ndipo siyingayambitsidwe;
2. Batire isanayambe kusungidwa, magetsi ndi zinthu zina zimakhala zachilendo, ndipo zimapezeka kuti magetsi ndi otsika kapena ngakhale zero pamene atumizidwa;
3. M'chilimwe, ngati GPS yagalimoto imayikidwa pagalimoto, mphamvu kapena nthawi yogwiritsira ntchito idzakhala yosakwanira pakapita nthawi, ngakhale batire ikuphulika.
Kudzitulutsa pawokha kumabweretsa kusiyana kwa SOC pakati pa mabatire ndi kuchepa kwa paketi ya batire
Chifukwa cha kusagwirizana kwadzidzidzi kwa batri, SOC ya batri mu paketi ya batri idzakhala yosiyana pambuyo posungirako, ndipo ntchito ya batri idzachepa. Makasitomala amatha kupeza vuto la kuwonongeka kwa magwiridwe antchito atalandira paketi ya batri yomwe yasungidwa kwakanthawi. Pamene kusiyana kwa SOC kufika pafupifupi 20%, mphamvu ya batire yophatikizidwa ndi 60% ~ 70% yokha.
Momwe mungathetsere vuto la kusiyana kwakukulu kwa SOC komwe kumayambitsidwa ndi kudziletsa?
Mwachidule, Timangofunika kulinganiza mphamvu ya batri ndikusamutsa mphamvu ya cell-voltage cell kupita ku cell-voltage cell. Pakali pano pali njira ziwiri: kusanja mokhazikika ndi kusanja mwachangu
Passive equalization ndikulumikiza chopinga chofananira ndi batri iliyonse. Selo likafika pakuwonjezera mphamvu, batireyo imathanso kulipiritsidwa ndikuyitanitsa mabatire ena otsika kwambiri. Kuchita bwino kwa njira yofananayi sikuli kwakukulu, ndipo mphamvu yotayika imatayika ngati kutentha. Kufanana kuyenera kuchitidwa pamalipiro, ndipo kufananiza komweko nthawi zambiri kumakhala 30mA mpaka 100mA.
Equalizer yogwiranthawi zambiri amalinganiza batire posamutsa mphamvu ndikusamutsa mphamvu zama cell ndi ma voliyumu ochulukirapo kupita ku maselo ena okhala ndi voteji yotsika. Njira yofananirayi imakhala ndi mphamvu zambiri ndipo imatha kufananizidwa m'maboma onse olipira ndi kutulutsa. Kufananiza kwake komweku kumakhala kokulirapo kambirimbiri kuposa momwe zimakhalira pano, nthawi zambiri pakati pa 1A-10A.
