In North America, voltage (V) represents the electrical potential that drives electrons, while current (measured in amperes, A) indicates the flow rate of electrons in an electrical circuit.
These two key parameters determine the total charging power (P), calculated as P = V × A. Higher voltage enables faster energy delivery, and sufficient amperage ensures the current meets the vehicle’s demand.
Properly matching voltage and current is essential for maximizing Electric Vehicle (EV) charging speed, maintaining safety, and ensuring compatibility with North American residential, commercial, and public charging stations.
