#### Example - Small Charging Station

From the diagram above - a small single phase AC 230V 16 amps charging station can deliver max 3.7 kW.

#### Example - Fast Charger

Current battery systems for electric cars typically use voltage levels between 200 and 800 V.

From the diagram above - a DC 400 V 125 amps fast charger can deliver max 50 kW.

#### Electric Power Nomogram

The nomogram below can be used to estimate power vs. voltage and ampere.
