Vana vakangwarira vanogona kuona kuti zvese zvinotakurika magetsi uye laptop zvine bhatiri rakafanana re5000mAh, asi iyo yekupedzisira yakakura kupfuura yekutanga.

Saka mubvunzo ndewokuti: Iwo ese mabhatiri e-lithium, asi nei mabhatiri mamwechete ari kure kure? Zvinoitika kuti kunyangwe ari ese ari maviri, asi kunyatsotarisisa, iwo voltages V uye Wh emabhatiri maviri pamberi mAh akasiyana.

Ndeupi musiyano uripo pakati pemAh neWh?

Milliampere awa (milliampere awa) ndiyo unit yemagetsi, uye Wh ndiyo unit yesimba.

Aya mafungire maviri akasiyana, fomula yekushandura ndeiyi: Wh=mAh×V(voltage)&Pide;1000.

Kunyanya, maawa emamiliampere anogona kunzwisiswa sehuwandu hwehuwandu hwemaerekitironi (nhamba yemaerekitironi anopfuura nepakati penguva ye1000 milliampere-maawa). Asi kuverenga simba rose, tinofanira kuverenga simba re electron imwe neimwe.

Ngatitii tine 1000 milliampere emaelectrons, uye voltage yerekitironi imwe neimwe i 2 volts, saka tine maawa mana ewatt. Kana erekitironi imwe neimwe iine 4v chete, tinongova neawa imwe chete yesimba.

Sezviri pachena, ndinoda peturu yakawanda sei, yakadai serita imwe; Wh inoreva kuti rita rimwe repeturu rinogona kusvika papi. Kuti tiverenge kuti rita rimwe remafuta rinogona kusvika papi, tinofanira kutanga taverenga kutamiswa. Muchiitiko ichi, kusunungurwa ndiko V.

Naizvozvo, kugona kwemhando dzakasiyana dzemidziyo (nekuda kwekusiyana kwevoltage) kazhinji haigone kuyerwa. Mabhatiri eLaptop anotaridzika akakura uye ane simba zvakanyanya, asi anoita basa rakawanda kupfuura mabhatiri enhare panguva imwe chete, uye haatore nguva yakareba kupfuura magetsi enhare.

Sei vamiririri vachishandisa Wh panzvimbo yemAh semuganhu?

Vanhu vanogara vachibhururuka nendege vanogona kuziva kuti Civil Aviation Administration ine inotevera mirau pamabhatiri e lithium:

Chishandiso chemagetsi chinotakurika chine lithium bhatiri chiyero chisingapfuure 100Wh chiri kukwira, uye haigone kuvanzwa mumukwende uye kutumirwa. Simba rose rebhatiri remidziyo yese yemagetsi inotakurwa nevafambi haifanire kudarika 100Wh. Lithium mabhatiri anodarika 100Wh asi asingadariki 160Wh anoda mvumo yendege yekutumira tsamba. Lithium mabhatiri anodarika 160Wh haazotakurwi kana kutumirwa.

Isu hatifanire kubvunza chete, nei iyo FAA isingashandise maawa-milliampere sechikamu chekuyera?

Tichifunga kuti bhatiri rinogona kuputika, kusimba kwekushandiswa kwekuputika kunoenderana zvakananga nehukuru hwesimba (Wh ndiyo unit unit), saka simba remagetsi rinofanira kutsanangurwa semuganhu. Semuenzaniso, 1000mAh bhatiri idiki kwazvo, asi kana bhatiri voltage inosvika 200V, ipapo ine 200 watt-maawa esimba.

Sei nharembozha dzichishandisa milliampere-maawa pachinzvimbo chewatt-maawa kutsanangura 18650 lithium mabhatiri?

Nharembozha lithium bhatiri masero ane kukosha kukuru, nekuti vanhu vazhinji havanzwisise pfungwa yewatt-maawa. Chimwe chikonzero ndechekuti 90% yenharembozha lithium mabhatiri mabhatiri e3.7V polymer. Iko hakuna musanganiswa wenhevedzano uye parallel pakati pemabhatiri. Nokudaro, simba rekutaura zvakananga Harizokonzeri kukanganisa kwakawanda.

Imwe 10% yakashandisa 3.8 V polymer. Kunyangwe paine musiyano wemagetsi, pane musiyano pakati pe3.7 ne3.8. Naizvozvo, zvakanaka kushandisa tsananguro yemAh yebhatiri mukushambadzira kwenharembozha.

Chii chinonzi bhatiri remalaptop, makamera edhijitari, nezvimwe?

Iwo magetsi ebhatiri akasiyana, saka anonyatso kucherechedzwa newatt-maawa: malaptop-akadzika-ekupedzisira ane simba renge anosvika makumi matatu-30 watt-maawa, epakati-renji malaptops ane simba renji rinosvika makumi matanhatu watt-maawa, uye akakwira. -mabhatiri ekupedzisira ane simba re 40. -60 watt-maawa. Simba remagetsi emakamera edhijitari i80 kusvika ku100 watt-maawa, uye nharembozha dzinowanzoita gumi watt-maawa.

Nenzira iyi, unogona kushandisa laptops (60 watt maawa), nharembozha (10 watt maawa) uye digitaalinen makamera (30 watt maawa) kubhururuka pedyo muganhu.
