Chiyambi:
Ndi chitukuko chofulumira cha makampani opanga mphamvu zatsopano, mabatire a lithiamu, monga chipangizo chofunika kwambiri chosungiramo mphamvu, akhala akugwiritsidwa ntchito kwambiri pamagalimoto amagetsi, machitidwe osungira mphamvu, magetsi ogula ndi zina. Pofuna kuonetsetsa chitetezo, kudalirika ndi magwiridwe antchito a mabatire a lithiamu, kuyesa kwasayansi ndikuwunika kwakhala kofunikira. Monga chida chachikulu cha ndondomekoyi,zida za lithiamu batiregwira ntchito yofunika kwambiri. Nkhaniyi ifotokoza mwatsatanetsatane gulu, mfundo ntchito ndi kufunika kwa lithiamu batire zida kuyezetsa ntchito zosiyanasiyana.
Kufunika koyezetsa batire la lithiamu
Kuchita kwa mabatire a lithiamu kumakhudza mwachindunji moyo wawo wautumiki, kulipira ndi kutulutsa bwino, komanso chitetezo. Pofuna kuonetsetsa kukhazikika ndi kudalirika kwa batire, kuyezetsa kokwanira kuyenera kuchitidwa, kuphatikiza koma osawerengeka ku mphamvu, kulipira ndi kutulutsa ntchito, kukana kwamkati, moyo wozungulira, mawonekedwe a kutentha, ndi zina zotere. konzani kamangidwe ka batri, komanso thandizani opanga kukonza zinthu zabwino ndikuchepetsa zoopsa zachitetezo.
Mitundu ya zida zoyesera batire la lithiamu
Pali mitundu yambiri ya zida zoyesera za batri ya lithiamu malinga ndi zofunikira zosiyanasiyana zoyesa ndi njira zoyesera. Iwo akhoza kugawidwa makamaka m'magulu awa:
1. Choyesa mphamvu ya batri
Kuchuluka kwa batri ndi chizindikiro chofunikira kuyeza mphamvu yosungira mphamvu ya mabatire a lithiamu.Zoyesa kuchuluka kwa batriNthawi zambiri amagwiritsidwa ntchito kuyesa mphamvu zenizeni za mabatire a lithiamu. Njira yoyeserayi imaphatikizapo kuyang'anira momwe batire imathamangitsira ndi kutulutsa batire ndikujambulitsa kuchuluka kwa magetsi omwe amatha kutulutsidwa batire ikatulutsidwa kumagetsi omaliza (mu Ah kapena mAh). Chida chamtundu uwu chikhoza kudziwa kusiyana pakati pa mphamvu yeniyeni ndi mphamvu yadzina ya batri kupyolera mu kutulutsa nthawi zonse.
2. Battery charge and discharge test system
Makina oyesera a batri ndi kutulutsa ndi chida choyesera champhamvu chomwe chitha kutsanzira momwe amathamangitsira ndikutulutsa pakagwiritsidwe ntchito. Dongosolo loyeserali limagwiritsidwa ntchito nthawi zambiri kuti lizindikire momwe batire likuyendera bwino, moyo wake wozungulira, kuchuluka kwake komanso kutulutsa kwa batire. Imayesa magwiridwe antchito a batri pansi pamikhalidwe yosiyana yogwirira ntchito ndikuwongolera moyenera magawo monga charge and discharge current, charge voltage, discharge voltage and time.
3. Battery mkati kukana woyesa
Kukana kwa batri mkati ndi chimodzi mwazinthu zofunika zomwe zimakhudza magwiridwe antchito a mabatire a lithiamu. Kukaniza kwambiri mkati kungayambitse kutentha kwa batri, kuchepetsa mphamvu komanso mavuto a chitetezo. Thebatire mkati kukana testeramawerengera kukana kwa mkati mwa batire poyesa kusintha kwamagetsi kwa batri pansi pazifukwa zosiyanasiyana komanso kutulutsa. Izi ndizofunika kwambiri pakuwunika thanzi la batri ndikulosera moyo wa batri.
4. Battery simulator
Batire simulator ndi chida choyesera chomwe chitha kutsanzira kusintha kwamagetsi ndi mawonekedwe amakono a mabatire a lithiamu. Nthawi zambiri amagwiritsidwa ntchito popanga ndi kuyesa makina oyendetsa mabatire (BMS). Imatsanzira machitidwe amphamvu a batri pakugwiritsa ntchito kwenikweni kudzera pakuphatikiza katundu wamagetsi ndi magetsi, kuthandiza ogwira ntchito ku R&D kuyesa kuyankha kwa kasamalidwe ka batri pamalipiro osiyanasiyana ndi kutulutsa.
5. Njira yoyesera zachilengedwe
Kuchita kwa mabatire a lithiamu kudzasintha pazikhalidwe zosiyanasiyana zachilengedwe monga kutentha ndi chinyezi. Chifukwa chake, njira yoyesera zachilengedwe imagwiritsidwa ntchito kutengera momwe mabatire a lithiamu amagwirira ntchito pansi pazikhalidwe zosiyanasiyana zachilengedwe ndikuyesa kukana kwawo kutentha kwambiri, kutentha pang'ono, chinyezi ndi magwiridwe ena. Izi ndizofunikira kwambiri pakuwunika kukhazikika ndi chitetezo cha mabatire m'malo apadera.
Mfundo yogwiritsira ntchito lithiamu batire tester
Mfundo yogwiritsira ntchito lithiamu batire tester imachokera ku mawonekedwe a electrochemical a batri ndi mawonekedwe amagetsi panthawi yamalipiro ndi kutulutsa. Kutengabatire mphamvu testermwachitsanzo, imapereka mphamvu yokhazikika kuti ikakamize batri kuti itulutse pang'onopang'ono, imayang'anira kusintha kwa magetsi a batri mu nthawi yeniyeni ndikuwerengera mphamvu zonse za batri panthawi yotulutsa. Kupyolera mu mayesero obwerezabwereza ndi kutulutsa, kusintha kwa ntchito kwa batri kumatha kuyesedwa, ndiyeno thanzi la batri likhoza kumveka.
Kwa tester yotsutsa mkati, imayesa kusinthasintha kwa magetsi ndi zamakono panthawi yamalipiro ndi kutulutsa batri, ndikuwerengera kukana kwa mkati mwa batri pogwiritsa ntchito lamulo la Ohm (R = V / I). Kutsika kukana kwamkati, kuchepa kwa mphamvu kwa batri ndi ntchito yabwino.
Zida Zoyezera Battery za Heltec
Zida zoyezera batire la lithiamu ndi zida zofunika zowonetsetsa kuti mabatire a lithiamu akuyenda bwino komanso akugwira ntchito. Amathandizira ogwira ntchito ku R&D, opanga, ogwira ntchito yosamalira mabatire ndi ogwiritsa ntchito kumapeto kuti amvetsetse bwino zisonyezo zosiyanasiyana zamabatire, potero kuonetsetsa chitetezo ndi kudalirika kwa mabatire pakagwiritsidwe ntchito.
Heltec imapereka zida zosiyanasiyana zoyesera batire ndizida zokonzera batri. Oyesa mabatire athu ali ndi ntchito monga kuyezetsa mphamvu, kuyesa kulipiritsa ndi kutulutsa, ndi zina zambiri, zomwe zimatha kuyesa molondola magawo osiyanasiyana a batri, kumvetsetsa moyo wa batri, ndikupereka mwayi ndi chitsimikizo pakukonza batri motsatira.
