The speed of electrons flowing through a wire is measured by volts (V) for electricity and the pressure, or force, is measured with amps (A).Ĭonsumption of electricity by a given device (watts) is measured by multiplying amps by volts, or W=(A*V). The speed of water flowing through a hose or pipe is measured in gallons per minute, while pressure in the hose or pipe is measured in pounds per square inch (PSI). In the case of water, a hose or pipe is typically the conductor and similarly, with electricity, the electrons flow through wires made out of material such as copper or aluminum. Volts, Amps, Watts: The Basics of ElectricityĮlectricity is much like water in that it flows through a conductor from the source to the terminal device. To get the best result and ensure safety, follow the guidelines covered in this article. Repairing damages from improper electrical work can be costly and time-consuming so doing it right the first time with save you money and effort. If not done correctly, the likelihood of EV charging station failures, damage to your home’s electrical system or EV, and even injury, increases exponentially. Upgrading your home’s electrical system to support a Level 2 EV charging station, regardless of the project scope, requires disciplined planning and an expert with specific training in electrical work and EV charger safety requirements, such as load calculations.ĭoing a proper job of load calculations is a key success factor for EV charger installations. At-home charging remains the most convenient solution for owners of electric vehicles (EVs) as it allows you to charge your electric car overnight, avoiding long waits for public charging, and saving money by charging when utility prices are lower.
