Lapho uxhuma amabhethri e-lithium ngokuhambisana, kufanele kuqashelwe ukuvumelana kwamabhethri, ngoba amabhethri e-lithium afanayo angaguquguquki kahle azohluleka ukushaja noma ukushaja ngokweqile phakathi nenqubo yokushaja, ngaleyo ndlela acekele phansi ukwakheka kwebhethri futhi athinte impilo yalo lonke iphakethe lebhethri. . Ngakho-ke, lapho ukhetha amabhethri ahambisanayo, kufanele ugweme ukuxuba amabhethri e-lithium emikhiqizo ehlukene, amandla ahlukene, namazinga ahlukene amadala namasha. Izidingo zangaphakathi zokungaguquguquki kwebhethri yilezi: i-lithium battery cell voltage difference≤10mV, umehluko wangaphakathi wokumelana≤5mΩ, kanye nomehluko wamandla≤20mA.
Iqiniso liwukuthi amabhethri azungeza emakethe wonke amabhethri esizukulwane sesibili. Nakuba ukuvumelana kwawo kukuhle ekuqaleni, ukuvumelana kwamabhethri kuyawohloka ngemva konyaka. Ngalesi sikhathi, ngenxa yomehluko we-voltage phakathi kwamaphakethe webhethri kanye nokumelana kwangaphakathi kwebhethri kukuncane kakhulu, i-current enkulu yokushaja okuhlangene izokwenziwa phakathi kwamabhethri ngalesi sikhathi, futhi ibhethri lonakala kalula ngalesi sikhathi.
Ngakho indlela yokuxazulula le nkinga? Ngokuvamile, kunezixazululo ezimbili. Enye iwukwengeza i-fuse phakathi kwamabhethri. Uma i-current enkulu idlula, i-fuse izophephetha ukuze ivikele ibhethri, kodwa ibhethri nayo izolahlekelwa isimo sayo sokuhambisana. Enye indlela ukusebenzisa isivikeli esihambisanayo. Lapho umsinga omkhulu udlula, i-umvikeli ohambisanayoikhawulela amandla amanje ukuvikela ibhethri. Le ndlela ilula kakhulu futhi ngeke iguqule isimo esihambisanayo sebhethri.
