Quick charging Low rate charging Pulse current charging Intermittent charging
Peak voltage control charging dT/dt control charging -⊿V control charging Timer control charging
V : Battery voltage
I : Charge current
T : Battery temperature
①Main charging
②Storage (Self-discharge)
③Maintenance charging
Terminate charging by detecting battery peak voltage Terminate charging by detecting battery temperature rate Terminate charging by detecting specified battery voltage drop after peak voltage Terminate charging by counting elapsed time Charging by pulse current to compensate self-discharge after main charging to keep fully charged state Charging intermittently after main charging to return to fully charged state (Factor of recharging: battery voltage, elapsed time)
