LTO IS Li2TiO3
LPO IS LI-ION Lithium
LFP IS LiFePo4
Technical parameters.
Operating voltage 1.8V-4.5V, suitable for Li-ion LiFePo4 LTO.
Working principle:
capacitive degree of fly transfer charge porter, equalizer board connected to the battery will be above the start of equalization work, using the original new ultra-low internal resistance MOS, 2OZ copper thick PCB, equilibrium current 0-5.5A, the more balanced the battery current is smaller, reserved sleep switch wiring position, sleep off mode operating current is less than 0.1mA, equilibrium voltage accuracy within 5mv!
Static current of about 12 mAh, the recommended battery capacity to 60-300AH battery applicable!
Measured fault battery pack combination 4 string 25Ah equalization curve
As the battery battery cycle times increase, the battery capacity decay speed is inconsistent, causing the battery voltage to be seriously out of balance. The battery barrel effect will cause the battery to charge. The BMS system detects that the battery has entered the overcharge protection in advance. In fact, only one of the batteries is full, or let The BMS system detects that the battery enters the over-discharge protection state, which is actually caused by over-discharge of one of the lower-voltage batteries. After the device acts, each battery voltage reduces the capacity attenuation caused by the battery barrel effect and prolongs the problem. The battery pack has a service life.
