锂离子电池充电/放电特征,Li-ion Battery Charge/Discharge Feature
Li-ion Battery Charger & System Topology (1/2)
Li-ion Battery Charger & System Topology (2/2)
Li-ion Battery Charge Feature
Pre-charge current = 1/10 program charge current
Pre-charge threshold voltage = 2.8V (or 2.9V)
Constant current mode (CCM) charge current = program charge current
Constant voltage mode (CVM) threshold voltage = 4.2V
Termination charge current = 1/10 program charge current
Re-charge threshold voltage = 4.1V
