How to regulate charging current of a battery with
I''m wanting to regulate the DC current coming from a battery charger (AC battery charger) into a battery in an attempt to control the power consumption of the battery charger. I''m hoping the design is applicable to all battery types as it should just regulate the current irrespective of the type of charger, however I''m using a lead acid and Lithium Iron Phosphate battery.

Can I use a constant voltage and constant current LED driver to charge
Same applies to the constant current power supply. It will push constant current into battery until battery voltage rises high enough so the supply can''t output constant current any more. But at this point the voltage will be the max output voltage, e.g. 12V, which will be way too much for a 1S or 2S pack. And the constant current is huge, much

Constant Current Battery Charger circuit diagram and instructions
Only one resistor is needed to set the desired charging current and is calculated by dividing the difference in battery voltages by the charge current. So, for example if 4 high capacity (4000 mA hour) ni-cads are to be charged at 300 mA from a 12 volt battery, the resistor needed would be 12-(4*1.25)/0.3 = 23.3 ohms, or 22 ohms which is the nearest standard value.

View more6 FAQs about [How to control constant current power supply when charging battery]
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 do you charge a battery?
There are three common methods of charging a battery: constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit. Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.
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.
What is constant voltage charging?
Constant voltage charging is a method of charging at a constant voltage to prevent overcharging. The charging current is initially high then gradually decreases. A constant charging method characterized by high initial current when the voltage is low, then decreasing current as the voltage gradually increases.
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.
What is constant voltage & how does it work?
Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage. The current will then taper down to a minimum value once that voltage level is reached.
