Kodi kusungirako mphamvu zamagalimoto amagetsi kumayendetsedwa bwanji

The mphamvu yosungirako wa magalimoto oyendetsa magetsiimazindikiridwa makamaka kudzera m'mabatire. Batire ndi chipangizo chomwe chimasintha mphamvu zamagetsi kukhala mphamvu yamagetsi, yomwe imakhala yodziwika kwambiri ndi batri ya lithiamu-ion.

Mabatire a lithiamu-ion omwe amagwiritsidwa ntchito m'magalimoto oyendera magetsi nthawi zambiri amakhala ndi ma cell angapo. Selo lililonse limalumikizidwa ndi cholekanitsa chokulungidwa ndi zinthu zabwino komanso zoyipa. Zinthu za cathode nthawi zambiri zimagwiritsa ntchito ma oxides, monga lithiamu cobalt oxide, lithiamu manganate, ndi zina zambiri, ndipo ma elekitirodi olakwika nthawi zambiri amagwiritsa ntchito graphite.

Njira yosungira mphamvu ya mabatire a lithiamu-ion imatha kugawidwa m'magawo awiri: kuyitanitsa ndi kutulutsa. Pochajitsa, gwero lamagetsi limadutsa magetsi kudzera mu electrode yabwino ya batri, zomwe zimapangitsa kuti ma ion a lithiamu atseke pakati pa ma elekitirodi abwino ndi oipa. Panthawiyi, ma ion a lithiamu amachotsedwa ku electrode yabwino, amatumizidwa ku electrode yolakwika kudzera mu ma ion mu electrolyte, ndipo amaikidwa mu graphite ya zinthu zoipa za electrode. Panthawi imodzimodziyo, ma ion abwino mu electrolyte mu batri amasunthanso kuti asatengere mbali zamagetsi pakati pa ma electrode.

Pamene mphamvu yamagetsi yosungidwa ikufunika, zamakono zimalowa mu chipangizocho kuchokera ku electrode yolakwika, ndipo ma ion a lithiamu amasuntha mosiyana kuchokera ku electrode yolakwika kupita ku electrolyte pakati pa ma electrode abwino ndikubwerera kuzinthu zabwino za electrode. Panthawiyi, kuyenda kwa ma lithiamu ion kumayambitsa kutuluka kwa magetsi ndipo kumatulutsa mphamvu yamagetsi yosungidwa.

Kusungirako mphamvu ya batri yamagalimoto oyendetsa magetsi kumafunikanso kuganizira zizindikiro zina, monga mphamvu ya batri ndi magetsi. Mphamvu imatanthawuza mphamvu yamagetsi yomwe batire ya lithiamu-ion imatha kusunga ndikumasula, yomwe nthawi zambiri imayezedwa mu ma ampere-hours (Ah). Voltage ndi mphamvu yamagetsi ya lithiamu-ion batire. Nthawi zambiri, magetsi a DC amagwiritsidwa ntchito, monga 3.7V, 7.4V, etc.

M'magalimoto oyendetsa magetsi, kuti akwaniritse bwino mphamvu zosungirako ndi kutulutsa mphamvu, kuthandizira kachitidwe ka kayendetsedwe ka batri (BMS) kumafunikanso. BMS ndi chipangizo chomwe chimayang'anira ndikuwongolera paketi ya batri, yomwe imatha kutsimikizira chitetezo cha batri, kuwonjezera moyo wake ndikuwongolera mphamvu zamagetsi.

BMS makamaka imaphatikizapo masensa a kutentha, masensa apano, masensa ma voltage ndi tchipisi chowongolera. Sensa ya kutentha imagwiritsidwa ntchito kuyang'anira kutentha kwa paketi ya batri kuti ipewe kutenthedwa kapena kuzizira; sensa yamakono imagwiritsidwa ntchito kuti izindikire ndalama ndi kutulutsa panopa pakiti ya batri kuti iwonetsetse kuti panopa ili mkati mwa malo otetezeka; sensor yamagetsi imagwiritsidwa ntchito kuyang'anira voteji ya paketi ya batri kuti iwonetsetse kuti siyikuchulukira kapena kupitilira. Chip chowongolera chimakhala ndi udindo wosonkhanitsa deta ya sensor ndikuwongolera ndikuwongolera batire kudzera mu ma aligorivimu.

Kuphatikiza apo, kuti muwonjezere mphamvu zosungirako mphamvu zamabatire a lithiamu-ion, kuwongolera koyenera kwa batire ndi kutulutsa kumafunikanso. Mwachitsanzo, kuyitanitsa nthawi zonse komanso kuyitanitsa ma voliyumu nthawi zonse kutha kugwiritsidwa ntchito pakuyitanitsa, ndipo magetsi otulutsa ndi magetsi amatha kusinthidwa malinga ndi zosowa pakutulutsa. Mwa kuwongolera moyenerera ndikuwongolera ndi kutulutsa, mphamvu yosinthira mphamvu ya batri imatha kukulitsidwa ndipo moyo wantchito wa batri utha kuwonjezedwa.

Nthawi zambiri, kusungirako mphamvu zamagalimoto am'manja kumatheka kudzera mu mabatire a lithiamu-ion. Mabatirewa amasunga mphamvu zamagetsi ndikuzitulutsa pakafunika. Kupyolera mu chithandizo cha kasamalidwe ka batri, chitetezo ndi ntchito ya batri ikhoza kutsimikiziridwa. Pa nthawi yomweyo, mwa kukhathamiritsa chaji ndi kutulutsa kuwongolera, mphamvu yosungiramo mphamvu imatha kuwongolera komanso moyo wa batri ukhoza kukulitsidwa. Kukula kosalekeza ndi luso laukadaulo wosungira mphamvu kupititsa patsogolo chitukuko ndi kugwiritsa ntchito mafoni
