If I''m understanding correctly, the solar power was around 400V at 8-9A, which should equate to 30ish A / battery, which isn''t really all that high, so I wouldn''t expect there to be much voltage drop between the batteries. The voltage differential has to be 0 when you stop charging, and should start to reverse when you start discharging.
Essential tasks for EVs charging equipment are the ability to quickly charge the EVs battery, to detect the state of charge (SOC) of the battery and to adapt to various battery types and car models.

4. Charging behaviour greatly affects the PV-BS capacity integration results because the resulting load profiles are differently matched to the PV output, and charging time is such that the more charging is performed at midday the greater PV capacity and smaller BScapacity is required.
To design the optimal PV-BS capacity for EVCS at different venues, it is essential to consider user charging behavior, charging load modelling, operational control, and capacity optimization models. The following review examines recent research related to these aspects.
Large scale integration of solar PV power with high short-term variability raises questions about the reliability and continuity of supply.
