Constant voltage (CV) allows the full current of the charger to flow into the battery until it reaches its pre-set voltage. CV is the preferred way of charging a battery in laboratories.

How do constant current constant voltage devices work?

The devices work by not being constant current and constant voltage at the same time. You set a voltage (V) for the output. You set a current (A)for the output. It will supply constant V for any current up to A. When the current your circuit draws goes above A, then it will reduce the voltage to keep A at the value set. Example: V set to 10V; A

batteries

Thinking of a battery as a constant voltage source is no better than thinking of it as constant current. Batteries are not regulators. They are storage devices with internal resistance, internal capacitance, a variable SoC, and even a little bit of internal inductance. None of these things are consistent across all batteries of the same chemistry, and SoC isn''t

A PV Panel is a Constant Current Source?

A PWM will just connect the panel to the battery, which will drag the panel down to the battery voltage, so for a 12 volt battery it would charge at 2.7 amps (in the constant current portion of the curve) and 12 volts. Multiply them together and you get 32.4 watts. If we divide the two, 43/32.4 = 1.327 so the MPPT charger gets about 32.7% more power out of the panel than
