These voltage limits will have to be applied anyway, but they tend to be a hard stop. If the vehicle controller knows the current/power limits ahead of time then the battery pack can be protected and the user can be limited more gradually to avoid the sudden loss of power.
The current is limited to approximately 1A (≈1.25V / R2) in this battery limiter. Note that the minimum voltage drop across the limiter is about 2.5V. In your design, the point where the current starts to drop is the constant-voltage value from your regulator.
You cannot control both voltage and current simultaneously in a battery charger. If the voltage is held constant, then the current will be determined by the load (battery). Conversely, if you limit the current, the voltage will be less than it would have been without the limiting.
The current control system is commanded by a superimposed battery voltage controller aimed at bringing the battery terminal voltage to the fully-charged state while also limiting the maximum battery charging current.
A simple current limiter can be built using an LM317 IC regulator (LTspice simulation below). Install it between the input supply voltage and your constant-voltage circuit to limit the current. The current is limited to approximately 1A (≈1.25V / R2) in this setup. Rload (horizontal axis resistance value) simulates the increase in voltage as the battery charges.
For the purpose of designing the battery terminal voltage-limiting controller, the open-circuit voltage U oc and polarization voltage u p dynamics were treated as slow "disturbances", so that "fast" battery terminal voltage dynamic variations were primarily affected by the series resistance voltage drop .
