How Fast is Wireless Charging in Cars?

Wireless charging for electric vehicles (EVs) has been gaining traction as a convenient and futuristic way to power up your car. While it offers a cable-free solution, many potential EV owners wonder just how fast wireless charging in cars really is. In this article, we delve into the world of wireless EV charging, exploring its speed and efficiency.

Wireless charging for EVs

1. Wireless Charging Technology

Wireless charging for EVs utilizes a technology called Inductive Power Transfer (IPT). This system relies on electromagnetic fields to transfer energy from a charging pad (usually on the ground) to a receiver pad on the EV. The receiver pad converts the electromagnetic energy back into electricity to charge the vehicle's battery. The efficiency and speed of wireless charging depend on several factors.

2. Charging Power Levels

The speed of wireless charging in cars primarily depends on the power level of the charging system. Common power levels for wireless charging are 3.7 kW, 7 kW, and 11 kW. The higher the power level, the faster the charging process. For example, a 3.7 kW wireless charger may take several hours to fully charge an EV, while an 11 kW charger can significantly reduce the charging time.

3. Efficiency

Wireless charging systems are designed to be highly efficient, but there is some energy loss during the transfer process. The efficiency can vary depending on the quality of the system and the alignment between the charging pad and the receiver pad on the EV. Proper alignment is crucial for minimizing energy loss and ensuring faster charging.

4. Alignment and Positioning

Achieving optimal alignment and positioning of the EV over the charging pad is vital for maximizing the charging speed. Advanced wireless charging systems use sensors and automated alignment mechanisms to ensure precise positioning. However, the user's ability to park the car accurately also plays a role in the charging speed.

5. Battery Capacity

The capacity of the EV's battery also affects the charging speed. A larger battery will take longer to charge, even with a high-power wireless charger. However, wireless charging allows for convenient "top-up" charging, where you can replenish the battery during short stops, such as at a coffee shop or a parking garage.

6. Charging Infrastructure

The availability of wireless charging infrastructure can vary by region and is a critical factor in the overall charging speed. Some areas may have a robust network of wireless charging stations with high-power levels, while others may have limited coverage. The expansion of wireless charging networks is expected to improve the accessibility and speed of wireless charging for EVs.

7. Future Developments

As technology continues to advance, wireless charging systems are expected to become faster and more efficient. Research and development efforts are focused on increasing the power levels of wireless chargers, reducing energy losses, and enhancing the user experience. These developments will likely lead to even faster wireless charging for EVs in the future.


Wireless charging for electric vehicles is a convenient and cable-free solution for powering up your car. The speed of wireless charging depends on several factors, including the power level of the charging system, efficiency, alignment, battery capacity, and the availability of charging infrastructure. While wireless charging may not be as fast as some wired fast-charging options, it offers the convenience of hassle-free charging without the need for physical cables.
