6 FAQs about [Battery constant voltage and constant current power changes]

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.

What happens when a battery is fully charged?

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. The charge current is controlled to avoid overheating and the float voltage limited to avoid over-charging.

What is constant current & constant voltage?

Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Constant current/constant voltage is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.

What are the characteristics of a constant voltage source?

Characteristics of Constant Voltage Source: Fixed Output Voltage: The primary feature of a CV source is its ability to supply a consistent voltage output regardless of the load current. Varying Current: The output current changes depending on the load.

What is the transition between constant voltage and constant current?

The transition between constant voltage and constant current is automatic. As an example, consider a 24V battery system (with a maximum float voltage of 28V) and discharged down to 15V. 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.

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.
