Maɓalli 6 Maɓalli na Kariya don Neman Lokacin Siyan Batura Masu Wutar Lantarki a 2023

1.Kariyar yawan caji

Kariyar wuce gona da iri tana nufin: batir lithium a cikin aiwatar da caji, tare da ƙarfin lantarki ya tashi zuwa sama da ma'ana, zai kawo rashin tabbas da haɗari. Ayyukan kariya na overcharge na hukumar kariyar shine kula da wutar lantarki na fakitin baturi a ainihin lokacin, da kuma yanke wutar lantarki lokacin da cajin ya kai kololuwar kewayon wutar lantarki mai aminci, yana hana wutar lantarki ci gaba da tashi, don haka kunna wuta. rawar kariya.
Ayyukan kariya da yawa: Lokacin caji, hukumar kariyar za ta kula da wutar lantarki na kowane kirtani na fakitin baturi a cikin ainihin lokaci, muddin ɗayan igiyoyin wutar lantarki ya kai ƙimar kariya ta wuce gona da iri (tsohuwar wutar lantarki ta ternary ita ce 4.25V± 0.05). V, da tsoho overcharge ƙarfin lantarki na LiFePO4.75V ± 0.05V), hukumar za ta yanke wutar lantarki, da dukan rukuni na lithium baturi. zai daina caji.

2.Over-fitarwa kariya

Kariyar wuce gona da iri tana nufin: batirin lithium a cikin aikin fitarwa, tare da raguwar ƙarfin lantarki, idan duk wutar lantarki ta ƙare zuwa gaji, kayan sinadarai da ke cikin baturin lithium zasu rasa aiki, wanda ke haifar da caji cikin ƙarfi ko raguwar ƙarfin aiki. Aikin kariyar wuce gona da iri na hukumar kariyar shine kula da wutar lantarki na fakitin baturi a ainihin lokacin, da kuma yanke wutar lantarki lokacin fitarwa zuwa mafi ƙasƙanci.na ƙarfin baturi, yana hana wutar lantarki ci gaba da faɗuwa, ta yadda za a taka rawar kariya.

Ayyukan kariya daga sama-sama: Lokacin fitarwa, hukumar kariyar za ta kula da wutar lantarki na kowane kirtani na fakitin baturi a cikin ainihin lokaci, muddin ɗayan igiyoyin wutar lantarki ya kai ƙimar kariya ta sama-saba (tsofaffin wutar lantarki na sama da ƙasa na ternary shine 2.7V ± 0.1V, kuma tsohowar wutar lantarki na LiFePO4 shine 2.2V± 0.1V), hukumar zata yanke wutar lantarki, da duka rukunin. na batirin lithium zai daina fitarwa.

3.Kariya ta wuce gona da iri

Kariyar kariya ta wuce gona da iri tana nufin: baturan lithium a cikin wutar lantarki zuwa kaya, halin yanzu zai canza tare da ƙarfin lantarki da canje-canjen wutar lantarki, lokacin da halin yanzu yayi girma sosai, yana da sauƙin ƙone allon kariya, baturi ko kayan aiki. Babban aikin kariya na hukumar kariya shine kula da halin yanzu na fakitin baturi a cikin ainihin lokaci yayin aiwatar da caji da caji, kuma lokacin da na yanzu ya wuce iyakar aminci, zai yanke abin wucewa ta yanzu, yana hana motsi na yanzu.m lalata batura ko kayan aiki, don taka rawar kariya.

Ayyukan kariya na overcurrent: lokacin caji da fitarwa, hukumar kariyar za ta kula da fakitin baturi a cikin ainihin lokaci, muddin ya kai ƙimar kariya ta wuce gona da iri, kwamitin kariya zai yanke wutar lantarki, da duka rukunin batir lithium. zai daina caji da fitarwa.

4.high / low zafin jiki kariya

Kariyar kula da yanayin zafi: Binciken kula da zafin jiki na allon kariyar kayan aiki ana walda shi zuwa uwa na ciki na allon kariya kuma ba za a iya cire shi ba. Binciken kula da zafin jiki na iya lura da canjin zafin baturin baturi ko yanayin aiki a cikin ainihin lokacin, lokacin da yawan zafin jiki ya wuce ƙimar da aka saita (tsoho na kariyar sarrafa zafin jiki na hardware: caji -20 ~ 55 ℃, fitarwa -40 ~ 75 ℃, wanda za a iya canza bisa ga abokin ciniki ta bukatun, da abokin ciniki ba zai iya saita shi da kansa), da baturi fakitin za a katse daga caji da fitarwa, da baturi fakitin iya ci gaba. da za a caje da fitarwa lokacin da aka mayar da zafin jiki zuwa kewayon da ya dace don taka rawa a cikin kariya.

5.Kariyar daidaitawa
Daidaitaccen daidaituwa yana nufin: lokacin da rashin daidaituwar wutar lantarki tsakanin igiyoyin batura, hukumar kariyar za ta daidaita wutar lantarki ta kowane kirtani don daidaitawa yayin caji p.roce.

Ayyukan daidaitawa: Lokacin da hukumar kariyar ta gano bambancin wutar lantarki tsakanin jerin baturin lithium da kirtani, lokacin da ake caji, manyan igiyoyin wutar lantarki sun kai darajar daidaitawa (ternary: 4.13V, LiFe3.525V), fitarwa (ci) tare da resistor daidaitawa tare da A halin yanzu na kusan 30-35mA, kuma sauran ƙananan igiyoyin wuta suna ci gaba da caji. Ci gaba har sai an cika.

6.short kewayawa kariya (gano kuskure + anti-reverse dangane kariya)
Gajeren kewayawa yana nufin: gajeriyar kewayawa tana samuwa ne lokacin da aka haɗa tashoshi masu inganci da mara kyau na baturinctly ba tare da wani kaya ba. Gajeren kewayawa zai haifar da lalacewa ga baturi, kayan aiki da sauransu.

Aikin kariyar gajeriyar kewayawa: batirin lithium ba da gangan ba ya haifar da gajeriyar kewayawa (kamar haɗa layin da ba daidai ba, ɗaukar layin da ba daidai ba, ruwa da sauran dalilai), allon kariya zai kasance cikin ɗan gajeren lokaci (0.00025 seconds) , yanke hanyar da ke cikin halin yanzu, don taka rawar kariya.
