To avoid local grid overload and guarantee a higher percentage of clean energy, EV charging stations can be supported by a combined system of grid-connected photovoltaic modules and battery storage.
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
The BMS also features a dedicated alternator and system port. The alternator port will "current limit" the alternator current. It can be set for a variety of currents all the way up to 100A.
