TL;DR – Zvauchadzidza muMasekondi makumi matatu:
• Nzira yekuchaja yelithium-ion ndeyeCC-CV (Constant Current-Constant Voltage).
• CC chikamu chinopa kukurumidza kuchaja (kusvika ku60-80% simba), CV chikamu chinochengetedza yakachengeteka topping-off uye inodzivirira hupenyu hwebhatiri.
• Kupisa kwakanyanya (pasi pe0°C kana pamusoro pe45°C) kunokanganisa kuchaja.
• Yakazvipira Battery Management System (BMS) yakakosha kune chaiyo voltage uye ikozvino mutemo.
Kuchaja kwaunoita lithium-ion bhatiri ndechimwe chezvinhu zvakakosha zvinotaridza hupenyu hwayo, kuita kwayo, uye kuchengeteka. Kunyangwe zvingaite senge mashandiro enguva dzose, iyo lithium-ion charge process inomira yakaparadzana neyekare bhatiri tekinoroji senge lead-acid kana NiMH. Kutevera akanakisa maitiro ndiko kwakakosha kudzivirira kusashanda uye kuwedzera ROI.
Nei iyo Lithium-Ion Charge process yakasarudzika
Kusiyana nemabhatiri e-lead-acid, masero e-lithium-ion haakwanise kushivirira kubhadharisa. Vanoda yakanyatsodzorwa yekuchaja ikozvino uye voltage kuti ive nechokwadi chekuti lithium ion inopinda zvakachengeteka muzvikamu zveanode graphite. Iyo yakajairwa, indasitiri-inogamuchirwa nzira yekuchaja yakakwana uye yakachengeteka yelithium-ion ndiyo CC-CV (Constant Current-Constant Voltage) algorithm. A robust Battery Management System (BMS) yakakosha kuita iyi algorithm nemazvo.
Danho 1: Constant Current (CC) - The Fast Charging Phase
Munguva yenguva inogara iripo, charger inopa yakatsiga, yakafanotemerwa ikozvino.
• Hunhu : Voltage inokwira zvishoma nezvishoma asi ikozvino inoramba yakagadziriswa.
• Kugona Kwakawanikwa : Bhatiri reLi-ion rinogona kusvika 60% kusvika 80% yehuwandu hwayo panguva ino.
• C-Rate : Yakanakira kuchaja parizvino inotangira pakati pe0.2C ne1.0C. Kune 2000mAh sero, chiyero che 0.5C chingave 1000mA.
• Transition Point : Chikamu cheCC chinoenderera mberi kusvikira magetsi esero asvika pakakwirira, kazhinji akapoteredza 4.2V pasero.
Danho rechipiri: Constant Voltage (CV) - Iyo Inodzivirira Topping-Off
Kana iyo 4.2V pachikumbaridzo yasvika, charger inochinja zvisina mutsindo kuenda kunogara voltage mode.
• Hunhu : Chaja inobata voltage yakadzikama uku iyo yazvino ichidzikira zvishoma nezvishoma.
• Sei Zvichidiwa : Pasina iyi CV nhanho, yazvino yaizoramba ichisundira maion mukati, zvichiita kuti metallic lithium iite plate pane anode, chikonzero chikuru chekupisa kwekupisa.
• Kugumiswa : Iyo lithium-ion charge cycle inopera, kana kupera, kana chaji chiripo ichidzika kusvika padanho re 'kupera kwechaji', kazhinji pakati pe0.02C ne0.07C.
Maitiro Akanakisisa uye BMS Monitoring
Kuchaja manejimendi haaitike mune vacuum. Kune chaiwo-epasi maapplication senge data nzvimbo kana telecom base zviteshi, yakasimba
Battery Management System (BMS) yakakosha.
✅
Tembiricha Monitoring : Kuchaja kunofanirwa kuitika pakati pe0°C ne45°C.
✅
Sarudzo yeChaja : Gara uchishandisa charger yakagadzirirwa Li-ion chemistry inotevera iyo chaiyo CC-CV mbiri.
✅
Voltage Precision : BMS yemhando inoita kuti sero rega rega risvike pamhepo yakakwana, kuwedzera huwandu hwese kutenderera kwechaji.
Chaiyo-Nyika Zvishandiso mune Yakakosha Simba
Misimboti yeyakachengeteka uye inoshanda lithium-ion kuchaja haisi yedzidzo chete; iwo ndiwo hwaro kune emazuva ano magetsi ekuchengetedza masisitimu. Mukati meUPS, lithium mabhatiri anopa yakakwira simba density kune mamwe compact backup simba. Iyo chaiyo yeCC-CV nzira yakakosha pakuvimbika. Pamusoro pezvo, kukura kwekushandiswa kwesimba rezuva uye Battery Energy Storage Systems (BESS) inotsamira pane yakaomesesa yekuchaja algorithms kuti iwedzere hupenyu hwekubatanidza simba rinogoneka nekuchengetedza bhatiri.
Kune mishoni-yakakosha maapplication, DFUN inopa yepamusoro lithium-ion bhatiri mhinduro dzakagadzirirwa kushanda zvisina musono nepuratifomu yedu yeBMS, kuve nechokwadi chekuita kwekuchaja kwakaringana, hupenyu hwakareba hwekutenderera, uye kuchengetedzwa kwakawedzera.
