For EV owners, home charging solutions provide both convenience and economic benefits, potentially transforming the whole driving and refuelling experience. But, as with anything new, the myriad of charger options can make choosing the right one a daunting task. This article will take a closer look at the different types of home EV chargers and go over some essential factors to consider when purchasing one.
Home Charging Options
As the heart of your EV charging experience, selecting the right charger type is crucial. There are two primary types of home EV chargers: portable and wall-mounted chargers, each with unique advantages.
Portable Home EV Charger
Portable EV chargers, also known as “granny cables,” offer a plug-and-play solution for EV charging. These chargers can be used with a standard household power outlet, providing excellent flexibility for those who travel frequently. You can easily take a portable charger with you, ensuring you can charge your vehicle wherever there’s a standard power socket. While their versatility is a significant advantage, portable chargers generally offer slower charging speeds compared to their wall-mounted counterparts.
Wall-Mounted Home EV Charger
If speed is your primary concern, wall-mounted chargers, often referred to as “wallboxes,” might be the ideal choice. They are permanently installed on a wall in your home or garage and hardwired into your home’s electrical system. Wall-mounted chargers provide faster charging speeds and often include additional features like programmable charging schedules or remote control through smartphone apps. However, as they require professional installation to ensure safety and compliance with electrical regulations, they can be more expensive than portable chargers.
Things to Consider When Buying a Home EV Charger
Purchasing an EV charger is a significant decision that warrants careful consideration of a few important factors:
Which EV You Own
The specifications of your EV largely determine the type of charger you need. Different EVs have different charging capabilities and port types, so ensure that your chosen charger is compatible with your vehicle.
Power Availability in Your Home
The power capacity of your home’s electrical system is also crucial. Your home must be able to handle the extra load an EV charger brings. This is especially important when considering a high-powered, wall-mounted charger, as you might need to upgrade your electrical system.
Desired Charging Speed
When choosing an EV charger, your lifestyle and driving patterns also matter. Think about how fast you’d need to replenish your vehicle’s battery routinely. If you frequently use your EV for long trips or have little time to wait for charging, you might lean towards a Level 2 or even Level 3 charger.
EV Charger Levels
Chargers are classified into different levels based on their power output and charging speed:
Level 1
Level 1 chargers are the most basic and use a standard household electrical outlet. They offer slow charging speeds, which can be sufficient for plug-in hybrids or if you only drive short distances with your EV. However, for fully electric cars or longer commutes, Level 1 charging might be impractically slow, taking up to 24 hours for a full charge.
Level 2
Many people find that Level 2 chargers are the sweet spot for home charging. They offer significantly faster charging speeds than Level 1 chargers, fully charging an EV in just a few hours. That said, they do require the installation of a dedicated 240-volt circuit, similar to what you would use for a home air conditioner or an electric oven.
Level 3
Level 3 chargers, also known as DC Fast Chargers, are the fastest charging solution available. Some of them can charge an EV battery to 80% in just 20-30 minutes. However, due to their high cost, power requirements, and the complex installation process, Level 3 chargers are typically used in commercial settings rather than residential homes.
Final Thoughts
Selecting the best home EV charger hinges on understanding the different options and a careful assessment of your vehicle’s charging compatibility, your residential electrical capabilities, and your preferred charging speed. Remember, it’s not a one-size-fits-all solution. If you’re feeling uncertain, don’t hesitate to get in touch with a trusted EV charger installation expert who can provide personalised guidance.
