Mawallafi: Iflowpower - Mai Bayar da Tashar Wutar Lantarki

Kayayyakin lantarki, musamman samfuran lantarki waɗanda ya kamata a ɗauka tare da ku, za su yi amfani da batir lithium-ion waɗanda za su zama sarrafa wutar lantarki don batir lithium-ion, wanda zai haɗa da cajin baturi na lithium-ion, fitarwa, tsarin gwajin ƙarfin lantarki. Gwajin kayan aikin baturi. Mun tsara samfura saboda daidaiton buƙatun ƙarfin baturi ba su da girma, kuma ana amfani da ADCs na ciki da ke cikin microcontroller, kuma wutar lantarki ta magana kuma tana ba da wutar lantarki ga microcontroller.

Gabaɗaya, 3.3V ana amfani dashi azaman ƙarfin magana. Don gwajin ƙarfin lantarki na baturin lithium ion, tun da ƙarfin baturin lithium ion na iya zama har zuwa 4.

2V, idan cajin waje ya kasance ko da 5V ko 6V ƙarfin lantarki, guda-guntu cikakken kewayon shine 3.3V, don haka ana amfani da resistors guda biyu a jere, microcomputer guda-gutu Ana ƙididdige ƙarfin lantarki don tattara ƙarshen resistor na ƙarfin lantarki don ƙididdige ƙimar ƙarfin lantarki na baturin lithium ion a cikin rabon matsin lamba. Sashen saye na ADC na software, kowane saitin guntu guda ɗaya ya bambanta, daidaito ya bambanta, anan ana ɗauka don lissafin dabarar, 12-bit ADC jimlar tsari na 4096th, ɗauka cewa ƙarfin rarraba juriya biyu resistors 100K ne, idan an tattara darajar ADC shine 1234, sannan ƙimar ƙarfin lantarki da aka tattara ta ninka sau 2 ta ninka sau 2: 23. coefficients, sa&39;an nan kuma raba ta 4096 matakai, ƙarfin lantarki darajar ne 3778mV.

Formula: ƙarfin lantarki na baturi = (Ƙimar Tarin Yanzu * Ƙimar Matsi * Wutar Lantarki) / Bayarwa ADC. Zaɓin guntu na sarrafa cajin baturi yana cajin alamar guntu, sau da yawa muna la&39;akari da kwanciyar hankalin guntu, cajin girman halin yanzu, cajin wutar lantarki, da farashin guntu don yin la&39;akari sosai. Za mu iya amfani da SGM4056 na Holy Bang, idan ƙarfin baturi ba shi da girma, ana iya sarrafa shi a cikin 350mV, wannan guntu kuma na iya ba da cajin ra&39;ayoyin ra&39;ayi.

Menene zargin da ake yiwa na&39;ura mai kwakwalwa mai kwakwalwa guda daya?. Microcontroller na software na microcomputer guntu guda ɗaya don batirin lithium ion yana iya bambanta, ba caji, caji, caji. Yaya waɗannan manyan batura uku suke? Lokacin da ba&39;a cajin baturin lithium ion ba, tsarin tsarin guntu ɗaya ba shi da caja na waje, kuma ƙarfin lantarki da microcontroller ke tarawa ba zai wuce 4 ba.

3V. Range tsakanin ƙarfin yanke yanke baturi ~ 4.2V.

Lokacin da ake cajin cajin waje, gwajin ya fi 4.3V, kuma tsarin caji shine. Tsarin guntu guda ɗaya ne ke kula da shi, kuma lokacin da matakin fil na guntun sarrafa caji ya canza, idan ya zama babban matakin, yana nufin cewa cajin ya cika, kuma siginar amsawar cajin kowane iri na iya zama iri ɗaya, da fatan za a koma ga ƙayyadaddun ƙayyadaddun daidai.

A yayin amfani da tsarin fitarwa na yau da kullun, ana kuma yanke hukunci akan tarin ƙarfin lantarki, kuma yawan matsewar ƙarfin faɗakarwa yana lalacewa ta hanyar baturi ko kariyar baturi. Gabaɗaya, ana amfani da 3.4V azaman ƙimar kofa, wanda bai wuce 3 ba.

4V don kunna ƙararrawar ƙarfin baturi. Ya kamata a zaɓi bayanai a hade tare da halayen samfur. .
