3.2v 6ah 48v Bms Lithium Ion roj teeb pob
Electrochemical Performance: Initial Peev Xwm: Cell yuav tsum tau them ib 3.2 thiab tawm ib 3.3 nyob rau hauv 1h tom qab them tag nrho.cycle: Nyob rau hauv cov txheej txheem kuaj, lub cell yog thawj zaug them rau 3.65 V nrog ib tug tas li tam sim no ntawm 1I 1, thiab ces them toless tshaj. 0. Lub xovtooj tawm mus rau 2.5 V nrog qhov tsis tu ncua tam sim no ntawm 1I 1, tso tseg rau 30min, thiab tom qab ntawd nqa lub voj voog tom ntej rau 2000 zaug sib law liag. Ua haujlwm lub voj voog: 1/3I 1 tawm rau 23 vib nas this, tom qab ntawd 1/3I 1 tso tawm rau 8 vib nas this, ces 1/3I 1 them rau 23 vib nas this, ces 0.1I 1 tso tawm rau 26 vib nas this, kom txog rau thaum soc 20 feem pua, teem cia rau 30min. Rov ua dua cov kauj ruam saum toj no kom txog rau thaum tus nqi tso tawm tsawg dua los yog sib npaug rau 90 feem pua ntawm thawj lub peev xwm. Kev ua haujlwm kub qis: Cell yuav tsum tau them ib 3.2 thiab khaws cia rau hauv qhov ntsuas kub ntawm 4h. Tom qab ntawd tso tawm raws li 3.3.Room Temperature Storage Test: Cell yuav tsum tau them ib 3.2, ces khaws cia ntawm 25 degree ± 2 degree rau 28 hnub. Thaum kawg tso tawm ntawm tes ntawm 0.5 I 1 mus rau qhov kawg voltage.High Temperature Storage Test: Cell yuav tsum tau them ib 3.2, ces khaws cia ntawm 55 degree ± 2 degree rau 7 hnub. Tom qab sawv ntsug rau 5h, tso tawm ntawm tes rau 3.3.
