Bhatiri yekuchaja algorithm inoona kumhanyisa kuchaja, kuchaja nekukurumidza uye kuchaja kwakagadzikana

Zvinoenderana nezvinodiwa zvesimba zvechishandiso chekupedzisira, bhatiri paki inogona kunge iine zvimedu zvina kana lithium, iyo inogona kugadziridzwa neyakajairwa magetsi adapter: yakananga adapter, USB ports kana mota majaja. Pasinei nenhamba yemabhatiri, mhando yemidziyo yebhatiri kana adapta yemagetsi, aya mabhatiri mapaketi ane maitiro ekuchaja akafanana. Saka iyo yekuchaja algorithm yakafanana. Iyo yakakwana yekuchaja algorithm yelithium mabhatiri uye lithium polymer mabhatiri anogona kukamurwa kuita matanho matatu: inononoka kuchaja, kukurumidza kuchaja uye yakagadzikana kuchaja.

* Yakaderera ikozvino kuchaja. Inoshandiswa pakuchaja kwakadzika bhatiri. Kana magetsi ebhatiri adonha ne2.8V, inochajwa neyakagadzika parizvino ye0.1C.

* kukurumidza kuchaja. Kana magetsi ebhatiri akadarika chikumbaridzo chekuchaja, iko kuchaja kunowedzerwa kuti iwane kukurumidza kuchaja. Iko kukurumidza kuchaja ikozvino kunofanirwa kunge kuri pasi pe1.0C.

*Safety voltage. Munguva yekukurumidza kuchaja maitiro, kana bhatiri voltage yasvika 4.2V, inotanga kupinda muchikamu chekudzikamisa voltage. Muchiitiko ichi, kuchaja kunogona kumiswa neishoma yekuchaja ikozvino kana timer kana musanganiswa wezvose. Kuchaja kunogona kumiswa kana iyo shoma ikozvino iri pasi pe0.07C. Iyo timer inokonzeresa neyakagadzikwa nguva.

Machaja ebhatiri epamusoro anowanzo ane mamwe maficha ekuchengetedza. Semuenzaniso, kana tembiricha yebhatiri ikadarika hwindo rakapihwa, kazhinji 0°C kusvika 45°C, kuchaja kuchamiswa.

Nekubviswa kwezvimwe midziyo yakaderera-yekupedzisira, nzira dzazvino dzekuchaja dzemabhatiri e-lithium-ion/lithium polymer pamusika dzinobva pakubatanidzwa kwehunhu hwekuchaja kana zvinhu zvekunze zvekuchaja, kwete chete kuita zvirinani kuchaja, asiwo kune. kuchengeteka.

*Li-ion/polymer bhatiri yekuchaja muenzaniso-mbiri yekuisa 1.2a lithium bhatiri charger LTC4097

LTC4097 inogona kushandiswa seadapter yekutaurirana kana USB simba sosi yekuchaja imwe lithium ion/polymer bhatiri. Mufananidzo 1 idhizaini yechirongwa cheLTC4097 dual-input 1.2a lithium bhatiri charger, inoshandisa yakatsiga ikozvino uye voltage kudzikamisa algorithm pakuchaja. Paunenge uchichaja kubva kune yekutaurirana adapta magetsi, iyo inorongeka yekuchaja ikozvino inosvika 1.2A, nepo USB magetsi anosvika ku1A, uye achishingairira kuona kuvepo kwega rega rega voltage. Chigadzirwa chacho chinopawo USB ikozvino muganho. Zvishandiso zvinosanganisira pdas, MP3 players, digital cameras, portable medical and test equipment, uye mbozhanhare dzine zvikirini zvakakura zvemavara. Maitiro ekuita: Hapana chekunze microcontroller yekumisa kuchaja, kushingaira kuona uye kusarudzwa kwesimba rekuisa; programmable kuchaja ikozvino yekupinza yekutaurirana adapta kuburikidza nekupikisa 1.2; programmable USB kuchaja ikozvino kuburikidza nekupikisa 1; 100% kana 20% USB yekuchaja ikozvino kuseta, Iyo yekupinza magetsi inobuda uye NTC bias (VNTC) pini 120mA yekugona kutyaira, NTC thermistor input (NTC) pini inochajwa pane yakatarwa tembiricha, bhatiri inoyangarara voltage iko ± 0.6%, LTC4097 inogona kushandiswa seadapter yekutaurirana kana USB simba rekupa kune imwechete lithium Charge ion/polymer bhatiri. Kuchaja kunotora yakachengeteka ikozvino / yakachengeteka voltage algorithm. Paunenge uchichaja kuburikidza neiyo yekutaurirana adapta magetsi, iyo inogoneka kuchaja ikozvino inosvika 1.2A, uye USB magetsi anosvika ku1A. Uye kana paine inoshanda kuona yevoltage yega yega yekuisa terminal. Chishandiso chinopawo USB ikozvino muganho. Zvishandiso zvinosanganisira pdas, MP3 players, digital cameras, portable medical and test equipment, uye mbozhanhare dzine zvikirini zvakakura zvemavara.
