Charging four steps, the #battery #charge has such a major problem

 

#Lithium #batteries in use with the release of #electricity, the #voltage drop, the battery's #chemical activity will be reduced. In order to better protect the performance of lithium batteries, lithium batteries will generally require charging process by trickle charge (low voltage precharge), constant current charging, constant voltage charging and charging termination of four stages, for control.

The standard charging process is: to set the current constant current charging, the battery voltage rose to 4.20V, to constant voltage charging, to maintain the charging voltage of 4.20V. At this time, the charging current gradually decreases, when the current drops to set the charge current of 1/10, the charge is over.

Phase 1: #Trickle Charge - Trickle Charge is used to precharge the fully discharged battery cell (rechargeable charge).

Phase 2: Constant #Current Charge - When the battery voltage rises above the trickle charge threshold, the charge current is increased for constant current charging.

Phase 3: #Constant #Voltage Charging - When the #battery voltage rises to 4.2V, the constant current charge ends and the constant voltage charging stage begins.

Phase 4: #Charging is terminated.
