There are so many kinds of EV chargers in the market, which making it difficult to distinguish which one is best fit for us. because individual factors play a big role in selecting the right charger. If you are facing this problem, ask yourself the following questions before making your decision:
Which Charging Speed Do You Prefer?
People usually consider either a Level 1 or Level 2 EV charger for home use. A Level 1 EV charger can operate directly on a standard 110V outlet, while a Level 2 EV charger requires a 240V outlet, typically installed by a professional electrician. The difference in input voltages results in varying charging speeds.
For example, if you own an AMPROAD iFlow P9 portable EV charger, which can work with adaptive voltage (90-250V), setting the power output at 40A will yield different charging speeds. On a Level 1 outlet, the charging speed will be 4.4kW/h. However, when charging the EV on a dedicated 240V Level 2 outlet, the speed can go up to 9.6kW/h. This demonstrates that the charging speed of a Level 2 charger is faster than a Level 1 EV charger, given that their power outputs are the same.
At this point, someone might ask, "Why not choose a Level 3 EV charger, which would be many times faster?" Level 3 EV charger, also known as DC fast charger, are indeed much faster than Level 1 and Level 2 chargers. They can charge an electric vehicle to 80% capacity in as little as 20-30 minutes, depending on the vehicle and the charger. This speed is achieved by using direct current (DC) rather than alternating current (AC), and by operating at significantly higher power levels, often between 50 kW and 350 kW.
However, there are several reasons why Level 3 chargers are not typically used for home charging. Firstly, the installation cost for a Level 3 charger is considerably higher than for Level 1 or Level 2 chargers. These chargers require substantial electrical infrastructure, including higher-capacity wiring, transformers, and other equipment that can handle the high power output. This makes Level 3 chargers prohibitively expensive for most homeowners. Additionally, the electrical requirements for a Level 3 charger are beyond what is available in a typical residential setting. Upgrading a home's electrical system to support a Level 3 charger would be an extensive and costly process, often involving coordination with local utility companies and significant modifications to the electrical grid.
How Many Amps Can Your Circuit Carry?
Another crucial factor to consider when selecting a home EV charger is the amperage capacity of your home's electrical circuit. The amperage of the circuit determines how much electrical current it can safely carry. Level 1 chargers typically require 15-20 amps, while Level 2 chargers usually need 30-60 amps. It's essential to ensure that your home's electrical system can support the charger you choose without overloading the circuit.
Consulting with a professional electrician can help you determine your home's electrical capacity and whether any upgrades are necessary to accommodate a Level 2 EV charger. Overloading a circuit can lead to tripped breakers, potential damage to your electrical system, and safety hazards.
What Type of Connector Does Your Car Require?
Different EVs use different types of connectors, so it's important to ensure that the home EV charger you choose is compatible with your vehicle. Most EVs in North America use the J1772 charger connector for Level 1 and Level 2 charging. This connector is compatible with nearly all electric vehicles sold in the region, including popular models from Tesla, which come with an adapter for J1772 connectors.
However, if you drive a vehicle that uses a different connector, such as the CHAdeMO or CCS for Level 3 charging, you'll need to ensure that your home charger is compatible or that you have the appropriate adapter. It's always best to check your vehicle's specifications and consult with the manufacturer if you have any doubts about compatibility.
Will You Install the Home EV Charger Indoors or Outdoors?
Where you plan to install your home EV charger can influence your choice. If you have a garage or covered parking area, an indoor installation might be more convenient and protect the charger from the elements. However, if you need to install the charger outdoors, you'll want to choose a unit that is weatherproof and designed for outdoor use.
Outdoor chargers should have a high IP (Ingress Protection) rating, indicating that they are resistant to dust and water. For instance, a charger with an IP66 rating can withstand heavy rain and dust, making it suitable for outdoor installation. Additionally, outdoor chargers should be robust and durable to endure various weather conditions over time.
Are You Looking for a Permanently Installed or Portable EV Charger?
When deciding on a home EV charger, you also need to consider whether you prefer a permanently installed unit or a portable EV charger. Each option has its advantages and considerations.
A permanently installed Level 2 EV charger, often referred to as an EV wall charger, is mounted on a wall or a dedicated stand and is hardwired into your home's electrical system. This type of charger offers a fixed and reliable charging solution, ensuring that you always have a charging station available at home. It's a great option for those who do most of their charging at home and want a clean, uncluttered setup.
On the other hand, a portable EV charger offers flexibility and convenience, allowing you to take the charger with you wherever you go. Portable chargers are especially useful for people who travel frequently, have multiple properties, or want the ability to charge their vehicle at different locations. While portable chargers may not offer the same high-speed charging as a permanently installed Level 2 EV charger, they provide a versatile and practical solution for on-the-go charging needs.
For those looking for a range of options to suit different needs, AMPROAD offers various home EV chargers. Their product line includes the permanent installed Wallbox EV charger for those seeking a fixed solution, the semi-permanent plug-in home flex for users who want a balance between stability and flexibility, and portable EV chargers for maximum mobility. This diverse range allows EV owners to choose the charging solution that best fits their lifestyle and charging requirements.
Energy Star Home EV Charger or Not?
Energy efficiency is another important factor to consider when selecting a home EV charger. Energy Star certified chargers are designed to be more energy-efficient, potentially reducing your electricity costs over time. These chargers meet strict energy efficiency guidelines set by the Environmental Protection Agency (EPA), ensuring that they consume less power during operation and standby modes.
AMPROAD offers a range of safe home EV chargers, including Energy Star certified models. Choosing an Energy Star EV charger can lead to lower energy consumption, translating to a smaller environmental footprint and cost savings on your electricity bill. Additionally, energy-efficient chargers often feature smart charging capabilities, allowing you to schedule charging during off-peak hours when electricity rates are lower.
Choose a Best Fit Home EV Charger
Choosing the right home EV charger involves considering various factors, including charging speed, circuit capacity, connector type, installation location, and whether you prefer a permanent or portable EVSE solution. Additionally, opting for an energy-efficient charger can provide long-term cost savings and environmental benefits.
By asking yourself these critical questions and evaluating your specific needs, you can make an informed decision that ensures a convenient, reliable, and cost-effective charging solution for your electric vehicle. Whether you choose a Level 1 charger for its simplicity, a Level 2 charger for its faster charging speeds, or an Energy Star certified charger for its efficiency, the right choice will enhance your EV ownership experience and contribute to a more sustainable future.
