Key Considerations for Understanding EV Charger Terminology
As electric vehicles (EVs) become more popular, many Orange County residents are considering installing EV chargers at home. However, the technical jargon associated with EV chargers can be confusing. This guide will help you understand key EV charger terminology so you can make informed decisions about your charging setup.
One of the first considerations when installing an EV charger is determining the amperage you need. The higher the amperage, the faster your EV will charge, but it’s important to match the charger’s amperage to both your vehicle’s onboard charger and your home’s electrical system.
For example, a Hyundai Ioniq 5, equipped with an 11 kW onboard charger, can benefit from a 48-amp charger, while a Toyota bZ4X, with its 6.6 kW onboard charger, won’t see improved charging performance beyond 30 amps.
To maximize efficiency, consider working with a local electrician to assess your home’s electrical capacity and choose the right charger. Avoid low-amperage chargers, as they may not provide sufficient power for newer EV models, and remember that hardwired EVSEs are recommended for chargers above 48 amps.
Another important factor is whether to opt for a hardwired or plug-in charger. A plug-in charger offers portability, allowing you to take it with you when you move or travel. However, plug-in chargers may not support as high an amperage as hardwired models, potentially leading to slower charging times.
Additionally, if you live in an area with frequent power outages, you might want to invest in a smart charger. Smart chargers can notify you if charging is interrupted and may even qualify for utility rebates, offsetting their higher initial cost. Consulting with a certified electrician can ensure that your setup is optimal for your specific needs, especially if you rely on a home generator during outages.

Key EV Charger Terms You Should Know
Ampere (amp):
An ampere, or amp, measures the electrical current running through a circuit. The amperage of your home’s electrical panel determines how much power can flow through your circuits. For example, older homes with 60-amp panels might struggle to power modern appliances while charging an EV. In such cases, you might need to upgrade your electrical panel, which can be a significant investment.
EVSE (Electric Vehicle Supply Equipment):
EVSE is the technical term for what most people call an EV charger. Ensuring that your EVSE is installed correctly and meets safety standards is crucial for efficient and safe charging.
Kilowatt (kW):
A kilowatt is a unit of electrical power. To determine the power output of your EV fast charger, multiply the voltage (240 volts) by the charger’s amperage rating, then divide by 1,000. This calculation provides the kilowatt output, which dictates the charging speed of your EV.
Kilowatt hour (kWh):
A kilowatt hour (kWh) measures the energy stored in a vehicle’s battery. Knowing your EV’s kWh capacity helps you understand how long it will take to charge your vehicle fully.
Types of EV Chargers
Level 2 Charger:
A Level 2 charger is a 240-volt charger that can be installed at home or in public places. It provides 20 to 40 miles of range per hour, making it an efficient option for overnight charging. Many homeowners in Orange County opt for Level 2 chargers because they are efficient and convenient.
NEMA (National Electrical Manufacturers Association):
NEMA sets standards for electrical products, including the types of plugs used in EV charging. Ensuring your EV charger and outlets comply with NEMA standards is essential for safety and compatibility.
Common EV Charger Connectors
Type 1 Connector (J1772):
Also known as J1772, this connector is widely used on American and European EVs that aren’t made by Tesla. If you own a plug-in hybrid electric vehicle (PHEV) or a battery electric vehicle (BEV), you’re likely familiar with this type of connector.
NACS (North American Charging Standard) Connector:
This connector, also called J3400, is a combination AC/DC charging plug used primarily on Tesla vehicles. With Tesla’s growing popularity, NACS connectors are becoming more common on EVs from other brands as well. Adapters are available to convert between NACS and other charging standards, like the Combined Charging System (CCS).
Important Considerations for Home EV Charger Installation
Voltage:
Voltage measures the force that moves electrical current. Higher voltage means faster charging. For example, a 240-volt outlet charges an EV much faster than a standard 120-volt outlet. That’s why most homeowners installing a Level 2 charger need a dedicated 240-volt circuit.
UL Listed:
When choosing an EVSE, it’s important to look for units that are UL-listed or ETL-listed. These certifications ensure the charger meets safety standards set by nationally recognized testing labs. All the chargers recommended by Copperfield Electric come with these safety ratings, giving you peace of mind.
Benefits of Installing an EV Charger at Home
Installing an EV charger at home offers numerous benefits. Not only does it provide the convenience of charging your vehicle overnight, but it also helps you avoid the higher costs associated with public EV charging stations. Additionally, a home EV charger can increase your property’s value and contribute to a cleaner environment by reducing reliance on fossil fuels.
