Kia Explains Differences Between AC and DC Charging for Electric Vehicles
Kia Deutschland GmbH has released information clarifying the distinctions between AC (Alternating Current) and DC (Direct Current) charging for electric vehicles. The guide aims to help EV owners understand and optimize their charging strategies.
Kia Clarifies AC vs. DC Charging for Electric Vehicles
Kia Deutschland GmbH has issued a detailed explanation differentiating between AC (Alternating Current) and DC (Direct Current) charging methods for electric vehicles. This information is presented to help EV owners better understand their charging options, whether at home, work, or on the go.
AC power, used by electrical grids, periodically reverses direction. DC power flows in a single direction and is the type of electricity stored in EV batteries. When an electric car is charged using AC, the vehicle's onboard charger converts the AC electricity to DC before it can be stored in the battery. This process is typically slower.
AC charging is the most common method for home and workplace charging. The conversion happens inside the car, which is generally considered gentler on the battery and more cost-effective for infrastructure. However, charging times are considerably longer; for instance, charging a Kia EV3 GT-Line to 100% with an 11kW home AC charger can take over 7 hours, making it suitable for overnight charging, which can be scheduled via the Kia Connect app.
DC charging, predominantly found at public charging stations, bypasses the car's internal converter and supplies DC power directly to the battery. This enables significantly faster charging speeds. Kia states its electric cars can achieve an 80% charge from 10% in as little as 18 minutes using DC chargers. To further improve speed, newer Kia models feature battery pre-conditioning, which automatically prepares the battery when a charging station is set as a navigation destination.
DC fast charging offers convenience and speed, especially for long journeys or when time is limited. It is beneficial for drivers needing a rapid recharge. Limitations include higher infrastructure costs and potential increased strain on the battery with frequent use of DC fast charging. Kia offers DC charging solutions ranging from 50 kW up to over 350 kW.
