Charging battery with constant voltage and current, with DC power supply
When the battery is at a low charge level, the voltage is below 4.2V. Upon connecting the battery, the current will jump to 1A. During this initial phase, the battery undergoes charging in constant current mode. The voltage of the cell gradually rises. Once the voltage reaches 4.2V, the charging mode transitions to constant voltage.

6 FAQs about [Lithium battery constant current power supply]
What happens when a battery is charged with a power supply?
When the discharged battery (at 15V) is connected to the power supply, the battery will start to charge at the pre-set constant current level. The current will remain constant until the voltage rises to 28V. At this point the power supply will transition to constant voltage mode and the current will decay to zero when the battery is fully charged.
How to charge a battery with a drooping power supply?
The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current. The other two characteristics should not be used to charge batteries.
How to charge a Li-ion battery in cc mode?
For a maximum current of 500 mA, a constant current source using a linear IC can be designed. By this constant current source, on trying to charge the Li-ion battery in CC mode, it was observed that during charging the actual voltage of the battery was 3.5 V which on charging by a maximum current of 500 mA, the battery voltage exceeded to 4 V.
What is a constant current battery?
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries.
How many volts does a battery charge?
According to the datasheet, the charging current is 1625mA and the charging voltage is 4.2V. Charging consists of two stages, first one is the constant current stage where you must supply a 1625mA constant current and when the battery voltage reaches 4.20V, the second stage starts, which is the constant voltage stage.
How to charge battery in CC & CV mode?
For charging the battery in CC and CV mode separate constant current and constant voltage source need to be designed. Both constant current and constant voltage sources can be designed using LM317 voltage regulator IC.
