Shanduko yekuburitsa voltage curve inoenderana nezvinhu zvakati wandei, zvinosanganisira kuburitsa ikozvino, tembiricha yebhatiri, kuchembera kwebhatiri, uye anodic zvinhu mhando inoshandiswa bhatiri.

Parizvino, mabhatiri akawanda e-lithium-ion anoshandisa coke kana graphite. Iyo voltage curve yebhatiri imwe neimwe inoratidzwa mumufananidzo. Iyo voltage yekuburitsa inosiyana zvakanyanya pakati pe20% uye 80% yesimba reiyo graphite zvinhu, uye yobva yadzikira nekukurumidza kumagumo, uye coke anode ine yakadzikama voltage slope uye yakaderera 2.

5V yekubvisa voltage. Paunenge uchishandisa coke zvinhu, iyo yakasara bhatiri huwandu huri nyore kuona, uye bhatiri voltage inongoyerwa. Mune parallel kana nhevedzano-yakabatana bhatiri yekufambira mberi kwesimba, lithium ion mabhatiri anowanzobatanidzwa mukufanana.

Pamusoro pebhatiri, iyo makemikari zvinhu zvinofanirwa kushandiswa, kubva kune imwechete mugadziri uye saizi, hapana zvimwe zvakakosha zvinodiwa. Iyo tandem yakabatana bhatiri inoda kungwarira, sezvo bhatiri kuenzanisa uye kuyera bhatiri maseketi kazhinji inoda kuve nechokwadi chekuti bhatiri rega rega rinosvika kune imwechete inoyangarara voltage uye yakafanana yekuchaja nhanho. Bata mabhatiri maviri akateedzana (ane anoteedzana bhatiri pack ekudzivirira maseketi) haakurudzirwe, nekuda kwehuwandu husina kufanana, nekudaro uchibvisa kubatana kwebhatiri.

Pamusoro pezvo, akawanda mabhatiri mapaketi akaunganidzwa kubva kumugadziri webhatiri anofanira kutengwa kubva kumugadziri webhatiri. Hupenyu hwepepa iri hunotarwa nezvinhu zvakawanda, uye zvakanyanya kukosha, bhatiri kemikari zvinhu, kudzika kwekubuda, tembiricha yebhatiri uye kukosha kwekumisa bhatiri. 100% kugona kubhatiri kuchaja kumugadziri anogona kusvika kuhuwandu hwekuchajisa / kuburitsa kutenderera kwakaziviswa nemugadziri.

Sarudza charger inovimbisa kuchaja kusvika pachiyero chisingasviki 100%, ichaita kuti application inoda kuwedzera hupenyu hwebhatiri ibatsirwe zvakanyanya, izvi zvinowanikwa nekusarudza bhatiri charger ine yakaderera inoyangarara voltage kana yekutanga kupera ch.
