As we stand at the cusp of a transportation revolution, the adoption of electric vehicles is dramatically increasing.

According to the National Renewable Energy Laboratory, it is estimated that only in the US there will be at least 33 million electric vehicles on the streets by 2030.

However, to fuel these modern marvels, we require a robust and reliable charging infrastructure – this is where Electric Vehicle Supply Equipment (EVSE) comes into play.

What is EVSE?

Electric Vehicle Supply Equipment, commonly known as EV charging stations or charging points, is the primary infrastructure that powers our electric cars.

Think of it as the fuel station for EVs. It is a system that consists of a power outlet, a control box, and a communication interface, all of which enable drivers to plug in, charge up, and monitor their vehicle’s charging status.

Why EVSE is crucial in the electric vehicle world?

EVSE is the backbone of the electric vehicle industry. With more EVs hitting the roads, the demand for a reliable and accessible charging system skyrockets.

You’ll find EVSE units in public places like parking lots, but many people also install them at home or in their businesses.

Most public EVSEs offer Level 2 charging, which provides up to 240 volts and an impressive 80 miles of range per hour.

The more advanced Level 3 is rarer due to its higher costs, but it offers up to 480 V and 200 miles of range per hour.

How does EVSE function?

While the EVSE is the connection point, the actual charging magic happens within the vehicle itself.

When you plug in, the EVSE and your vehicle communicate, deciding on the best charging rate.

Depending on the type of EV charger you’re using (AC or DC charging devices), the charging method differs. AC chargers power the onboard system in the EV, which then converts the power for the battery.

On the other hand, DC charging bypasses this system and directly powers the battery, offering faster charging (also known as dc fast charging) but at a steeper price.

What is EVSE?

It’s the equipment which allows you to recharge electric vehicles. Whether you’re at home or in public, you’re likely using an EVSE system comprising a charging cord, a connector, and a control box.

What is an EVSE charger?

Also known as an EV charging station, it’s the point that supplies your EV’s battery with electric power.

Which EVSE is the best?

The best EVSE depends on individual needs, the type of EV, the location of the charging station, and the preferred charging speed.

Is EVSE the same as a charging station?

Absolutely! People often use EVSE, charging station, or charging point interchangeably. They all refer to the system that provides electricity to charge up EV batteries.

How does an EVSE operate?

Simply put, EVSE offers electric energy to an EV. It chats with the vehicle, decides the charging pace, and then kicks off the charging process. However, the actual charging takes place within the vehicle.

Public vs. Private EVSE – What’s the difference?

Public EVSEs are like public parking – open for all EV owners. Private ones are for specific users, often installed in homes or workplaces, and are accessible only to a select few.
