Kodi C-rate ya Battery ndi chiyani?

C-rate ya batire ndi gawo lomwe limayesa liwiro la kuthamangitsa kapena kutulutsa batire, lomwe limadziwikanso kuti kuchuluka kwacharge/kutulutsa. Makamaka, C-rate imayimira ubale wochulukirapo pakati pa kuchuluka kwa batire / kutulutsa kwamagetsi ndi kuchuluka kwake komwe kudavotera. Fomula yowerengera ndi:

Mtengo / Kutulutsa = Kulipiritsa / Kutulutsa Panopa / Kuthekera kwake

Tanthauzo ndi Kumvetsetsa kwa C-rate

• Tanthauzo: Mlingo wa C, womwe umatchedwanso kuchuluka kwa ndalama / kutulutsa, ndi chiŵerengero cha mtengo / kutulutsa panopa ku mphamvu yadzina ya batri. Mwachitsanzo, kwa batri yokhala ndi mphamvu ya 100Ah, kutulutsa pakalipano ya 20A kumagwirizana ndi kutulutsa kwa 0.2C.

• Kumvetsetsa: Kutulutsa kwa C-rate, monga 1C, 2C, kapena 0.2C, kukuwonetsa kuthamanga. Mulingo wa 1C umatanthauza kuti batire ikhoza kutulutsa kwathunthu mu ola limodzi, pomwe 0.2C ikuwonetsa kutulutsa kwa maola asanu. Nthawi zambiri, mafunde osiyanasiyana otulutsa amatha kugwiritsidwa ntchito kuyeza kuchuluka kwa batri. Kwa batire ya 24Ah, 2C yotulutsa pano ndi 48A, pomwe 0.5C yotulutsa pano ndi 12A.

Kugwiritsa ntchito C-rate

• Kuyesa Kwantchito: Potulutsa pamitundu yosiyanasiyana ya C, ndizotheka kuyesa magawo a batri monga kuchuluka, kukana kwamkati, ndi nsanja yotulutsa, yomwe imathandiza kuwunika momwe batire ilili komanso moyo wautali.

• Zochitika Zogwiritsira Ntchito: Zochitika zosiyanasiyana zogwiritsira ntchito zimakhala ndi zofunikira zosiyanasiyana za C-rate. Mwachitsanzo, magalimoto amagetsi amafunikira mabatire okwera kwambiri a C kuti athamangitse / kutulutsa mphamvu, pomwe makina osungira mphamvu amaika patsogolo moyo wautali komanso mtengo wake, nthawi zambiri amasankha kutsika kwa C-rate ndikutulutsa.

Zomwe Zimakhudza C-rate

Magwiridwe A Ma cell

• Kuchuluka Kwa Maselo: C-rate kwenikweni ndi chiyerekezo cha mtengo / kutulutsa kwapano ndi kuchuluka kwa ma cell. Chifukwa chake, mphamvu ya selo imatsimikizira mwachindunji kuchuluka kwa C. Kuchulukira kwa mphamvu ya cell, kumachepetsa kuchuluka kwa C-kutulutsa komweku komweko, ndi mosemphanitsa.

• Maselo a Maselo ndi Kapangidwe kake: Zida ndi kapangidwe ka selo, kuphatikizapo zipangizo za electrode, ndi mtundu wa electrolyte, zimakhudza ntchito ya malipiro / kutulutsa ndipo motero zimakhudza C-rate. Zida zina zitha kuthandizira kulipiritsa ndi kutulutsa, pomwe zina zitha kukhala zoyenera kugwiritsa ntchito zotsika mtengo.

Battery Pack Design

• Kuwongolera Kutentha: Panthawi yolipira / kutulutsa, batire limatulutsa kutentha kwakukulu. Ngati kuwongolera kwamafuta sikukukwanira, kutentha kwamkati kumakwera, kumachepetsa mphamvu zamagetsi ndikusokoneza C-rate. Chifukwa chake, kapangidwe kabwino ka kutentha ndikofunikira kuti batri ikhale ndi C-rate.

• Battery Monitoring System (BMS) : BMS imayang'anira ndikuyang'anira batri, kuphatikizapo kuyang'anira malipiro / kutulutsa, kutentha, ndi zina zotero. Mwa kuwongolera molondola mtengo / kutulutsa pakali pano ndi magetsi, BMS imakonza bwino ntchito ya batri, motero imapangitsa C-rate.

Zinthu Zakunja

• Kutentha Kozungulira: Kutentha kwa chilengedwe ndi chinthu chofunikira kwambiri pakugwira ntchito kwa batri. M'malo otentha, kuthamanga kwachakudya kumachepa, ndipo kutulutsa kumachepa, kumachepetsa kuchuluka kwa C. Mosiyana ndi izi, kutentha kwambiri, kutentha kwambiri kumatha kukhudzanso C-rate.

• Battery's State of Charge (SOC): Battery's State of Charge (SOC): Battery ya SOC ikatsika, kulipiritsa kumakonda kukhala kofulumira, chifukwa kukana kwa mankhwala mkati kumakhala kotsika. Komabe, ikayandikira chiwongolero chonse, liwiro la kulipiritsa limachepa pang'onopang'ono chifukwa chakufunika kowongolera bwino kuti musachulukitse.

Chidule

C-rate ndiyofunikira kuti mumvetsetse momwe batire imagwirira ntchito pamikhalidwe yosiyanasiyana. Ma C-otsika (mwachitsanzo, 0.1C kapena 0.2C) amagwiritsidwa ntchito poyesa kwanthawi yayitali / kutulutsa kuti awunike mphamvu, mphamvu, komanso moyo wautali. Ma C-okwera kwambiri (monga 1C, 2C, kapena kupitilira apo) amawunika momwe batire imagwirira ntchito kuti iperekedwe mwachangu/kutulutsa zofunika, monga kuthamanga kwagalimoto yamagetsi kapena kuwuluka kwa drone.

Ndikofunikira kudziwa kuti C-rate yapamwamba sikhala yabwinoko nthawi zonse. Ngakhale mitengo ya C-high imathandizira kulipiritsa / kutulutsa mwachangu, imabweretsanso zovuta zina monga kuchepa kwachangu, kutentha kwakukulu, komanso moyo wautali wa batri. Chifukwa chake, posankha ndikugwiritsa ntchito mabatire, kulinganiza kuchuluka kwa C-rate ndi magawo ena ogwiritsira ntchito molingana ndi kagwiritsidwe ntchito ndi zofunikira ndikofunikira.
