But, as we indulge in the luxury of wire-free charging, a question lingers in the minds of many – can you fast charge wirelessly? In this article, we’ll delve into the world of wireless charging, exploring its limitations, the current state of fast wireless charging, and what the future holds.
The Basics Of Wireless Charging
Before we dive into the realm of fast wireless charging, it’s essential to understand the fundamental principles of wireless charging. Wireless charging, also known as inductive charging, uses an electromagnetic field to transfer energy between a transmitter (the charging base) and a receiver (the device to be charged). This technology relies on the principle of electromagnetic induction, where an electrical current is generated in the receiver coil when it’s placed within the magnetic field of the transmitter coil.
There are three primary types of wireless charging:
- Qi (pronounced “chee”) – an open standard developed by the Wireless Power Consortium
- AirFuel – a proprietary standard developed by the AirFuel Alliance
- PMA (Power Matters Alliance) – a proprietary standard developed by the Power Matters Alliance
Qi is the most widely adopted wireless charging standard, used by manufacturers like Samsung, Apple, and Google.
The Limitations Of Wireless Charging
Wireless charging, in its current form, has some limitations that hinder its ability to keep up with the demands of fast charging.
- Power Transfer Efficiency: Wireless charging is less efficient than traditional wired charging. The energy transferred wirelessly is typically around 70-80% efficient, compared to the 90-95% efficiency of wired charging. This means more energy is wasted as heat during wireless charging, leading to slower charging speeds.
- Distance and Alignment: Wireless charging requires the device to be in close proximity to the charging base, with the coils ideally aligned for optimal energy transfer. Misalignment or increased distance between the coils can significantly reduce charging speeds.
The Emergence Of Fast Wireless Charging
Fast wireless charging, also known as fast inductive charging, is an enhanced version of traditional wireless charging. It uses advanced technologies to increase the power transfer rate, making it more comparable to wired fast charging.
- Qi Fast Wireless Charging: The Wireless Power Consortium introduced Qi Fast Wireless Charging, which allows for power transfer rates of up to 15W. This is significantly faster than the standard 5W wireless charging, but still lags behind the speeds of wired fast charging.
- AirFuel Resonant Wireless Charging: AirFuel’s resonant technology enables faster power transfer rates, up to 50W, over longer distances. This technology uses a resonant coil to amplify the magnetic field, allowing for more efficient energy transfer.
Fast Wireless Charging Standards
Several fast wireless charging standards have emerged, offering varying levels of power transfer rates:
- Qi Extended Power Profile (EPP): Supports power transfer rates up to 15W
