How to control the voltage of the battery current
Current into or out of the battery at any voltage is measured by the IBS and reported to the ECU DME which adjusts voltage (out of the alternator via the BSD PWM signal from the ECU to the alternator) to cause the appropriate current flow. Alternator no-load voltage higher than battery voltage causes current into the battery. - Download [PDF]
How does Alternator control current to Battery?
Current into or out of the battery at any voltage is measured by the IBS and reported to the ECU DME which adjusts voltage (out of the alternator via the BSD PWM signal from the ECU to the alternator) to cause the appropriate current flow.

How to Design a Simple Constant Current/Constant Voltage …
A DC-to-DC converter is typically implemented as a constant voltage (CV) regulator. The control loop adjusts the duty cycle in order to maintain a constant output voltage regardless of changes to the input voltage and load current.

Current flow in batteries?
However, current more than likely won''t (depending upon the age/use of the battery). The reason why is because the voltage potential difference - the "excess holes on the positive end" and the "excess electrons on the negative end" - is relative to a given battery. There are excess electrons/holes on the ends of a given battery with respect to ...
