How is the charge current of EVSE affected by the voltage supplied?

The charge current of Electric Vehicle Supply Equipment (EVSE) is directly influenced by the voltage supplied. When the voltage is increased, according to Ohm's Law (current = voltage / resistance), it results in a higher charge current for a given resistance in the circuit. This higher charge current means that the vehicle’s battery can receive energy more quickly, thereby reducing the time it takes to charge the vehicle.

This principle underpinning electrical systems highlights that if the voltage is increased while maintaining a similar resistance level, the flow of current (or charge current in the context of EVSE) will also increase. Therefore, supplying a higher voltage to the charging system effectively speeds up the charging process, allowing electric vehicles to be charged more efficiently.

Other statements do not accurately represent the relationship between voltage and charge current. For instance, while lower voltage might indeed offer certain safety benefits, it does not directly relate to how the charge current is affected by the voltage. Similarly, stating that voltage does not influence charge rate overlooks the fundamental electrical principles that govern charging systems.
