Hi, I have a simulink model for charging and discharging lithium acid battery. It consists of two batteries one is working as a power source and the other working as a charging source for the other battery when it reaches below 20%. The charging and discharging model is controlled by a MATLAB function using circuit breakers. Now I want to replace the changing battery with PV block model. What are the power electronics should I use to connect it. Because when I connect it directly, some error appears such as (NaN). So how could I connect a PV block model to a battery to charge it?
