Electric cars can use two types of fuel: alternating current (AC) and direct current (DC). The power from the grid is always AC, but batteries, like the one in your EV, can only store DC power. To charge electronic devices, such as smartphones, the plug converts AC power to DC, making it compatible with the battery. Make sure to follow the merchant’s instructions for a professional and factual tone.
AC charging for electric vehicles
Electric vehicles typically have a converter, also known as an “onboard charger,” built into the car. This converter is responsible for converting AC power to DC power and supplying it to the car’s battery. This charging method is widely used in electric vehicles and relies on AC power.
DC charging for electric vehicles
When using power from the grid, it is important to note that it always operates on AC. The key distinction between AC charging and DC charging is where the conversion of AC power takes place: either inside or outside the car. Unlike AC chargers, DC chargers have the converter built into the charger unit, enabling them to directly supply power to the car’s battery without the need for an onboard converter. This advancement makes DC chargers larger, quicker, and a groundbreaking development for electric vehicles.
Where do I find AC charging? Where DC charging?
AC charging is commonly used by charging stations today with a charging speed of 22 kW, varying depending on the car and available power. It is suitable for charging at home or work, as it requires more time to complete. On the other hand, DC charging is more common at public stations and highways, which provide limited recharge time. However, DC charging is now being introduced in home charging, providing customers with new options for fast and bidirectional charging.
A guide to the two charging types, and what they mean for electric vehicle users
As a product or industry expert, you may have heard about ‘AC’ and ‘DC’ charging while considering or transitioning to an electric vehicle (EV). What is the distinction, and what should you be aware of?
Learn about the differences between AC and DC electric currents, which refer to alternating and direct current respectively. Each type has its own benefits, but DC charging generally offers a quicker charge for EV drivers. Here are 7 commonly asked questions we’ve answered for those looking to hit the road with confidence.
Learn about EV battery energy storage.
Although both AC and DC charging stations can charge an EV, the EV’s battery can only store DC energy.
So, how to charge an EV using AC?
EV drivers can utilize an AC charging point to charge their vehicles, as the car’s built-in converter will convert AC electricity to DC to be stored in the battery for use.
Could AC charging be made more efficient?
When charging an EV battery, converting AC energy to DC is necessary. This means that AC charging may take longer than DC charging. If you are on a trip, it is important to keep in mind the type of charging available to ensure you have enough time for recharging.
Where is AC charging typically used?
Electricity is supplied in homes through AC at a slower rate (7kW in some cases). Typically, a home charger will transfer power through a socket to a car converter to convert the energy into DC and store it in the car’s battery.
Guidelines for DC Charging.
When utilizing rapid or ultra-fast charging, the charging infrastructure will supply energy to your EV in DC, eliminating the need for conversion and allowing the energy to be directly transferred to the battery.
So, is DC charging always faster?
DC charging allows for higher speed charging as it does not require energy conversion, but charging speeds may vary depending on your EV make and model, as well as the charger being used.
