1. Iyiphi yamanje engcono kakhulu yamabhethri e-lithium aphinde ashajwe?

Amabhethri e-lithium kufanele ashajwe ngokuqhubekayo okwamanje, okungukuthi, kufanele kube khona okwamanje, futhi umthamo webhethri nenqubo yokushaja ikhula kancane kancane, lapho i-voltage yebhethri ingu-4.2V, kufanele ifinyelele ku-4.1V), ukuze ishaje njalo, hhayi I-voltage kufanele ibe nesisekelo sokushaja kwamanje kwesikali esigcwele esiqhubekayo kwenziwa ohlangothini olungenhla, futhi inqubo yokushaja iyancipha ngokuqhubekayo. Uma izinga lokushisa lehliswa libe ngu-0.01 degrees Celsius, ukushaja kuyamiswa. (C indlela yokuveza umthamo olinganiselwe webhethri ngokuya ngezamanje. Isibonelo, uma umthamo webhethri ungu-1000mAh, i-1C ingu-1000mA wokushaja. Qaphela ukuthi lena i-mA, hhayi i-Ah. Kungani ucabanga ukuthi 0.01C inkokhiso yokugcina: Lena indinganiso kazwelonke ye-GB / T18287-2000 nayo ebuyekeziwe. Esikhathini esidlule, siqede u-20mA. Izinga lembonini elingu-YD/T998-1999 loMnyango Wezokuthumela Nokuxhumana linemithetho efanayo, yokuthi ukuthi, kungakhathaliseki ukuthi ubukhulu bebhethri bukhulu kangakanani, i-stop current ingu-20mA. Izinga likazwelonke elingu-0.01c liwusizo ekushajeni Ngokugcwele kakhulu, lokhu kuyinzuzo eqinisekiswe umenzi. Ngaphezu kwalokho, izinga likazwelonke libeka ukuthi isikhathi sokushaja kufanele ingadluli amahora angu-8, okungukuthi, noma ingafinyeleli ku-0.01c, ithathwa njengokushaja kwamahora angu-8. (Ikhwalithi yebhethri ayinayo inkinga, futhi kufanele ibe phakathi kwamahora angu-8. 0.01 degrees Celsius, ayikho ibhethri elisezingeni elihle, futhi akunangqondo ukulinda) I-ch engcono kakhulu isilinganiso sokushaja se-lithium ion noma i-lithium yi-1 c, okusho ukuthi ibhethri engu-1000 mAh inesimanje sokushaja esisheshayo esingu-1000 mAh futhi izindleko yilesi. ukuphila. Ukuze kuzuzwe leli zinga eligculisayo lokushaja, kuyadingeka ukwandisa inani lamanje lokushaja lephakethe lebhethri njengoba umthamo ukhula.

2. Iyiphi i-voltage engcono kakhulu yamabhethri e-lithium aphinde ashajwe?

I-voltage yegama lebhethri ye-lithium ingu-3.7V (3.6V), futhi i-voltage yokunqanyulwa kweshaji ngu-4.2V (4.1V, kuye ngohlobo lwebhethri, futhi umklamo uhlukile). Ihlukaniswa kanjani i-4.1V ne-4.2V: Abathengi abakwazi ukuhlukanisa phakathi kwayo, futhi kuncike ekukhiqizeni ibhethri okucaciswe komkhiqizo woMkhiqizi. Ezinye izinhlobo zamabhethri ngokuvamile ziyi-4.1V kanye ne-4.2V, njenge-A&TB (Toshiba), abakhiqizi basekhaya bangama-4.2V. Kwenzekani uma ushaja ibhethri elingu-4.1V ukuya ku-4.2V? Lokhu kuzokhuphula umthamo webhethri futhi kwenze kube lula ukulisebenzisa. Cabanga ukusuka ku-500 kuye ku-300. Ngokufanayo, uma ibhethri le-4.2V lishajwe ngokweqile, impilo yalo izofushaniswa. Amabhethri e-lithium antekenteke. Uma ibhethri linebhodi lokuvikela, singalilungisa? Cha, ngoba ipharamitha enqanyuliwe yebhodi lokuvikela ingu-4.35V (kulungile, kodwa umehluko phakathi kwe-4.4V ne-4.5V), ngakho ibhodi lokuvikela kufanele libhekane nemvamisa emaphakathi. Uma ibhethri lishajwa njalo, lizoguga ngokushesha.

3. Ungakanani umthamo webhethri le-Apple iPhone?

Imininingwane yebhethri ye-Apple iPhone ine-voltage yegama engu-3.7V, i-voltage esike ukushaja engu-4.2V, kanye nomthamo webhethri ongu-1400mAh. Kuyabonakala kulokhu okungenhla ukuthi izinga lokushaja elilungile ngu-1C. Eyamanje edingekayo ukuze ifinyelele ku-1400mA iqala ukushaja ku-voltage engu-3.7V.

4. Ithini i-voltage kanye ne-current port ye-usb neshaja?

I-Usb interface yamanje ingu-500mA, i-voltage ingu-+5V. Uma uphenyisisa i-HWinfo ngenkathi ishaja, ungakwazi futhi ukubona ukunikezwa kwamandla kwangaphandle. Ishaja engu-500mA yakhelwe i-iPhone. Kafushane, lapho i-USB ishaja, i-voltage ingu-+5V futhi yamanje ingu-500mA kuphela. Kusukela ezimpendulweni zoMbuzo 1 kanye nombuzo 2, siyazi ukuthi le ndlela inyusa umthamo webhethri, okuyinto enhle ukuyisebenzisa, kodwa yehlisa impilo yebhethri. Uma usebenzisa ishaja ukushaja, singase sibuze, awushongo yini ukuthi ijubane elingcono kakhulu ngu-1C? Kulungile ukucabanga ukuthi i-iPhone kufanele ikhokhiswe i-current ye-1400mA, yebo, kodwa izwe linemithethonqubo. Izinga lokushaja eliphansi elicaciswe yi-gb ngu-0.2C. (Uhlelo lokushaja olulawulwayo), futhi thatha ibhethri le-iPhone elingu-1400mAh njengesibonelo, elingu-280mA. Ngokombono, ibhethri elincane, lizuza kakhulu. Kodwa awukwazi ukulinda izinsuku ezintathu ukuze ushaje ibhethri. (Umthamo mAh = wamanje mA x isikhathi h) Ngakho i-Apple ikhetha i-0.7C, amabhethri amaningi aphakathi kuka-0.5C no-0.8C, ungakhetha u-5! Ngokusobala, abanye abantu basebenzisa i-USB ukushaja, okuzwa impilo ende, kodwa leli ibhethri elikhethekile Inani lempilo
