Chiyambi：
Ndi chitukuko chachangu cha makampani atsopano amagetsi, mabatire a lithiamu, monga chipangizo chofunikira chosungiramo mphamvu, akhala akugwiritsidwa ntchito kwambiri m'magalimoto amagetsi, makina osungiramo mphamvu, zamagetsi ndi madera ena. Pofuna kuonetsetsa kuti mabatire a lithiamu ndi otetezeka, odalirika komanso ogwira ntchito, kuyesa ndi kuwunika kwasayansi kwakhala kofunikira. Monga chida chachikulu cha njirayi,zida zoyesera batire ya lithiamuimagwira ntchito yofunika kwambiri. Nkhaniyi ifotokoza mwatsatanetsatane za magulu, mfundo yogwirira ntchito, komanso kufunika kwa zida zoyesera batire ya lithiamu m'magwiritsidwe osiyanasiyana.
Kufunika kwa kuyesa batri ya lithiamu
Kugwira ntchito kwa mabatire a lithiamu kumakhudza mwachindunji nthawi yawo yogwirira ntchito, mphamvu ya chaji ndi kutulutsa, komanso chitetezo. Pofuna kuonetsetsa kuti batireyo ndi yokhazikika komanso yodalirika, mayeso athunthu ayenera kuchitika, kuphatikizapo koma osati kokha mphamvu, mphamvu ya chaji ndi kutulutsa, kukana kwamkati, nthawi ya kuzungulira, mawonekedwe a kutentha, ndi zina zotero. Mayesowa sangathandize ogwira ntchito za kafukufuku ndi chitukuko kukonza kapangidwe ka batire, komanso kuthandiza opanga kukonza ubwino wa malonda ndikuchepetsa zoopsa zachitetezo.
Mitundu ya zida zoyesera batire ya lithiamu
Pali mitundu yambiri ya zida zoyesera batire ya lithiamu malinga ndi zofunikira zosiyanasiyana zoyesera ndi njira zoyesera. Zitha kugawidwa m'magulu otsatirawa:
1. Choyesera kuchuluka kwa batri
Kuchuluka kwa batri ndi chizindikiro chofunikira poyesa kuchuluka kwa mphamvu zomwe mabatire a lithiamu amasungira.Oyesa mphamvu ya batriKawirikawiri amagwiritsidwa ntchito poyesa mphamvu yeniyeni ya mabatire a lithiamu. Njira yoyeserayi imaphatikizapo kuyang'anira njira yochapira ndi kutulutsa mphamvu ya batire ndikulemba kuchuluka kwa magetsi omwe angatulutsidwe batire ikatulutsidwa ku voltage yomaliza (mu Ah kapena mAh). Mtundu uwu wa chida ukhoza kudziwa kusiyana pakati pa mphamvu yeniyeni ndi mphamvu yeniyeni ya batire kudzera mu kutulutsa mphamvu kosalekeza.
2. Dongosolo loyesera la batri ndi kutulutsa mphamvu
Dongosolo loyesera la chaji ndi kutulutsa mphamvu ya batri ndi chida champhamvu choyesera chomwe chingayerekezere momwe chaji ndi kutulutsa mphamvu ya batri panthawi yogwiritsa ntchito. Dongosolo loyeserali nthawi zambiri limagwiritsidwa ntchito kuzindikira momwe batri imagwirira ntchito, nthawi yozungulira, momwe chaji ndi momwe imagwirira ntchito. Limayesa momwe batri imagwirira ntchito pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito powongolera molondola magawo monga chaji ndi kutulutsa mphamvu ya batri, magetsi a chaji, magetsi a kutulutsa mphamvu ndi nthawi.
3. Choyesera kukana kwamkati mwa batri
Kukana kwamkati mwa batri ndi chimodzi mwazinthu zofunika kwambiri zomwe zimakhudza magwiridwe antchito a mabatire a lithiamu. Kukana kwambiri kwamkati kungayambitse kutenthedwa kwambiri kwa batri, kuchepa kwa mphamvu komanso mavuto achitetezo.choyesera kukana kwamkati mwa batriimawerengera kukana kwa mkati mwa batri poyesa kusintha kwa magetsi a batri pansi pa mikhalidwe yosiyanasiyana ya chaji ndi kutulutsa. Izi ndizofunikira kwambiri poyesa thanzi la batri ndikulosera moyo wa batri.
4. Choyeserera batri
Choyeserera batire ndi chida choyesera chomwe chingayerekezere kusintha kwa mphamvu yamagetsi ndi mphamvu yamagetsi ya mabatire a lithiamu. Nthawi zambiri chimagwiritsidwa ntchito popanga ndi kuyesa machitidwe oyang'anira mabatire (BMS). Chimayerekezera momwe batire imagwirira ntchito pogwiritsa ntchito magetsi amagetsi ndi magetsi, zomwe zimathandiza ogwira ntchito za kafukufuku ndi chitukuko kuyesa momwe makina oyang'anira mabatire amayankhira pazochitika zosiyanasiyana zolipirira ndi kutulutsa mphamvu.
5. Njira yoyesera zachilengedwe
Kagwiridwe ka ntchito ka mabatire a lithiamu kamasintha malinga ndi nyengo zosiyanasiyana monga kutentha ndi chinyezi. Chifukwa chake, njira yoyesera zachilengedwe imagwiritsidwa ntchito kutsanzira momwe mabatire a lithiamu amagwirira ntchito pazochitika zosiyanasiyana zoopsa zachilengedwe ndikuyesa kukana kwawo kutentha kwambiri, kutentha kochepa, chinyezi ndi magwiridwe antchito ena. Izi ndizofunikira kwambiri poyesa kukhazikika ndi chitetezo cha mabatire m'malo apadera.
Mfundo yogwirira ntchito ya choyesera batri ya lithiamu
Mfundo yogwirira ntchito ya choyezera batire ya lithiamu imachokera pa makhalidwe amagetsi a batire ndi makhalidwe amagetsi panthawi yolipiritsa ndi kutulutsa.choyesera kuchuluka kwa batriMwachitsanzo, imapereka mphamvu yokhazikika yokakamiza batire kuti itulutse pang'onopang'ono, imayang'anira kusintha kwa magetsi a batire nthawi yeniyeni ndikuwerengera mphamvu yonse ya batire panthawi yotulutsa. Kudzera mu mayeso obwerezabwereza a chaji ndi kutulutsa, kusintha kwa magwiridwe antchito a batire kumatha kuyesedwa, kenako thanzi la batire limatha kumveka.
Pa choyesera chamkati, chimayesa kusinthasintha kwa magetsi ndi mphamvu yamagetsi panthawi ya chaji ndi kutulutsa mphamvu ya batri, ndikuwerengera kukana kwamkati kwa batri pogwiritsa ntchito lamulo la Ohm (R = V/I). Kukana kwamkati kukakhala kochepa, mphamvu ya batri imachepa ndipo magwiridwe antchito ake amakhala abwino.
Zipangizo Zoyesera Mabatire a Heltec
Zipangizo zoyesera mabatire a lithiamu ndi zida zofunika kwambiri kuti zitsimikizire kuti mabatire a lithiamu ndi abwino komanso amagwira ntchito bwino. Zimathandiza ogwira ntchito za kafukufuku ndi chitukuko, opanga, ogwira ntchito yokonza mabatire ndi ogwiritsa ntchito kumapeto kumvetsetsa bwino zizindikiro zosiyanasiyana za mabatire, motero kuonetsetsa kuti mabatire ndi otetezeka komanso odalirika akagwiritsidwa ntchito.
Heltec imapereka zida zosiyanasiyana zoyesera mabatire ndizida zokonzera batri. Oyesa mabatire athu ali ndi ntchito monga kuyesa mphamvu, kuyesa kuyatsa ndi kutulutsa mphamvu, ndi zina zotero, zomwe zimatha kuyesa molondola magawo osiyanasiyana a batire, kumvetsetsa nthawi ya batire, ndikupereka zosavuta komanso chitsimikizo cha kukonza batire pambuyo pake.
