Mabatire a lithiamu-ionzakhala zopezeka paliponse m'moyo watsiku ndi tsiku.Ali paliponse, kuyambira mafoni a m'manja mpaka ma laputopu, magalimoto amagetsi mpaka mabanki amagetsi.Mabatirewa ndi amphamvu, ophatikizana, ndipo amatha kusunga mphamvu.Komabe, mphamvu imeneyi imabwera ndi udindo.Kasamalidwe koyenera ndi chitetezo ndizofunikira pankhani ya mabatire a lithiamu-ion.
Chigawo chimodzi chofunikira pachitetezo ndi magwiridwe antchito a mabatire a lithiamu-ion ndi Battery Management System (BMS).BMS imayang'anira ndikuwongolera kuchuluka kwa batri, kutuluka, kutentha, ndi magetsi ndikuteteza batire kuti lisachuluke, kuthamangitsidwa, komanso ma frequency afupi.M'nkhaniyi, tiona mmene ntchito 4s Li-ion lithiamu 18650 batire BMS mapaketi PCB chitetezo bolodi.
Kodi 4s Li-ion lithium 18650 batire BMS mapaketi PCB chitetezo board?
Batire ya 4s Li-ion lithium 18650 BMS imanyamula bolodi lachitetezo cha PCB ndi bolodi laling'ono loyang'ana dera lomwe lapangidwa kuti liteteze batire ku zoopsa zosiyanasiyana monga kuchulukira, kutulutsa kwambiri, mabwalo amfupi, komanso kusinthasintha kwa kutentha.Bungweli lili ndi ma micro-controller unit (MCU), ma switch a MOSFET, resistors, capacitor, ndi zida zina zomwe zimagwirira ntchito limodzi kuyang'anira kuchuluka kwamagetsi a batri ndi kuchuluka kwapano komanso kuwongolera kuyitanitsa ndi kutulutsa batire.
"4s" m'dzina la BMS imatanthawuza kuchuluka kwa maselo mu batire paketi.18650 imatanthawuza kukula kwa maselo a lithiamu-ion.Selo la 18650 ndi cell ya cylindrical lithiamu-ion yomwe imayesa 18mm m'mimba mwake ndi 65mm m'litali.
Chifukwa chiyani 4s Li-ion lithiamu 18650 batire BMS mapaketi PCB chitetezo bolodi?
Kugwiritsa ntchito 4s Li-ion lithiamu 18650 batire BMS mapaketi PCB chitetezo bolodi n'kofunika chifukwa zimatsimikizira kuti batire otetezeka ndi moyenera.BMS idapangidwa kuti iteteze batri kuti lisachuluke, kutulutsa mopitilira muyeso, komanso kutentha kwambiri.Kuchucha mochulukira ndi kutulutsa mopitirira muyeso kungayambitse kuwonongeka kosasinthika kwa batire, kuchepetsa moyo wake, ngakhale kuyambitsa moto kapena kuphulika.
Kuphatikiza apo, BMS imayang'anira kusanja ma cell mu batire paketi.Maselo a lithiamu-ion ali ndi mphamvu yocheperako, ndipo ngati selo limodzi lachulukira kapena kulipiritsa pang'ono, zimatha kukhudza magwiridwe antchito ndi chitetezo cha batri.BMS imawonetsetsa kuti ma cell onse omwe ali mu batire paketi amachajitsidwa ndikutulutsidwa mofanana, kukulitsa moyo wa batri.
Momwe mungagwiritsire ntchito batri ya 4s Li-ion lithium 18650 BMS mapaketi a PCB chitetezo board?
Kugwiritsa ntchito 4s Li-ion lithiamu 18650 batire BMS mapaketi PCB chitetezo bolodi n'zosavuta ndipo safuna luso lapadera kapena zida.Komabe, m'pofunika kutsatira malangizo a Mlengi mosamala kuonetsetsa otetezeka ndi imayenera ntchito batire.
Nazi njira zogwiritsira ntchito 4s Li-ion lithium 18650 batire ya BMS mapaketi a PCB chitetezo bolodi:
Gawo 1: Sonkhanitsani zigawozo
Musanayambe kusonkhanitsa batire paketi, muyenera kusonkhanitsa zigawo zonse zofunika.Izi zikuphatikiza ma cell a 18650, bolodi la BMS, chosungira batire, mawaya, ndi chitsulo chosungunulira.
Gawo 2: Konzani ma cell
Yang'anani selo lililonse kuti muwonetsetse kuti silinaonongeke kapena lodetsedwa.Kenako, yesani mphamvu ya cell iliyonse pogwiritsa ntchito multimeter.Ma cell ayenera kukhala ndi ma voltages ofanana.Ngati maselo aliwonse ali ndi mulingo wosiyana kwambiri wamagetsi, zitha kukhala chizindikiro chakuti selo lawonongeka kapena lagwiritsidwa ntchito mopitilira muyeso.Bwezerani maselo owonongeka kapena olakwika.
Khwerero 3: Sonkhanitsani paketi ya batri
Lowetsani ma cell mu chotengera batire, kuonetsetsa kuti polarity ndiyolondola.Kenako, lumikizani ma cell angapo.
