Overdischarge kune zero voltage test:
Iyo STL18650 (1100mAh) lithium iron phosphate simba bhatiri yakashandiswa kuburitsa kusvika zero voltage test.Mamiriro ekuedzwa: 1100mAh STL18650 bhatiri yakachajiswa zvizere ne0.5C yekuchaja chiyero, uye yobva yaburitswa kune bhatiri voltage ye0C ine 1.0C yekuburitsa mwero.Zvadaro gurai mabhatiri akaiswa pa0V mumapoka maviri: rimwe boka rinochengetwa kwemazuva 7, uye rimwe boka rinochengetwa kwemazuva makumi matatu;mushure mekunge chengetedzo yapera, inochajiswa zvizere ne0.5C yekuchaja chiyero, uye yozoburitswa ne1.0C.Pakupedzisira, misiyano pakati penguva mbiri dze zero-voltage yekuchengetedza inofananidzwa.
Mhedzisiro yemuyedzo ndeyekuti mushure memazuva manomwe ekuchengetera zero voltage, bhatiri harina kubuda, kuita kwakanaka, uye kugona kuri 100%;mushure memazuva makumi matatu ekuchengetedza, hapana kudonha, kuita kwakanaka, uye huwandu huri 98%;mushure memazuva makumi matatu ekuchengetedza, bhatiri rinoiswa pasi pe 3 kubhadharisa-kubvisa mitsetse, Iyo simba inodzokera ku100%.
Muedzo uyu unoratidza kuti kunyangwe iyo lithium iron phosphate bhatiri yakawandisa (kunyangwe kusvika ku0V) uye yakachengetwa kweimwe nguva yenguva, bhatiri harizobvisike kana kukuvara.Ichi chinhu icho mamwe marudzi emabhatiri e-lithium-ion haana.
