Electric vehicles (EVs) have become more popular over the recent past as more environmentally-friendly and cost-effective alternatives. Most people get the motivation to switch to EVs due to the rising fuel costs.
Some governments also offer lucrative incentives for people to switch from gas-powered cars to EVs. However, potential EV owners often hesitate due to charging concerns.
Although charging an EV requires prior planning, the process is simple, and you can install a charging station at home.
Read on for insights on how EV chargers work and why you should consider getting an EV charger at home.
What are EV Chargers?
Like your smartphone, an EV requires charging to ensure enough power to run the vehicle.
An EV charger or charging station is a device or tool that helps replenish EV batteries and plug-in hybrid electric vehicles (PHEVs). The charging process is simple: the charger delivers electrical power from the grid to the EV’s battery.
The EV has a charging cable or EVSE (Electric Vehicle Supply Equipment). One end of the charging cable goes into the EV’s charging port, while the other fits into the power outlet.
There’s two-way communication between the EV and the EV charging station for safety purposes. The electricity moves through the charging cable but waits for the signal from your EV to deliver power.
You can charge your EV at your workplace, public charging station, or at home.
Charging Levels
There are three EV charging levels: Level 1, Level 2, and Level 3. Generally, the higher the charging level, the more the power output and the faster your EV charges.
Level 1 – Portable EVSE
Level 1 charging refers to charging your EV through a standard 120-volt outlet. This charging method lasts longer, adding about 3 to 4 miles (5 to 6 km) of range every hour.
For instance, if you have a PHEV with an electric range of 53 miles, it will take about 13 hours to recharge the battery. Slow chargers only work if you can charge your EV overnight or rarely drive long distances.
Level 2 – Wall Chargers
Most EV owners use Level 2 chargers installed at home. These chargers require a 240-volt outlet, and the charging process is faster.
You can charge the same PHEV with an electric range of 53 miles in about 2 hours and 15 minutes. Furthermore, you can connect a level 2 charger to your solar system to save more on energy costs.
Level 3 – DC Fast Chargers
DC fast chargers or Level 3 chargers are the fastest, increasing your EV’s driving range by about 80 miles (129 km) within 20 minutes. However, not all EVs are compatible with level 3 chargers.
These rapid chargers require a high voltage of 480+ volts and advanced technology to install and maintain. They are, therefore, more suitable for industrial and commercial uses.
While level 1 and 2 chargers carry alternating current (AC), level 3 chargers deliver direct current (DC) directly to the EV battery.
Conclusion
Charging your EV at home is the cheapest and most convenient option. Most homes can accommodate a level 2 charger without elaborate or extensive upgrades.
You’ll need a dedicated 240-volt circuit for your charging station, much like an electric clothes dryer requires. Rather than attempting to DIY, call an electrician to install your EV chargers.
