Stay Safe and Secure: Understanding Wireless Charging Safety

Wireless charging systems have been in development for quite a period of time. This technology provides the user with a “Hands-free” method of charging, while also introducing some safety features that are unique to wireless charging.

Design and safety standards are being developed, and these standards will be required to ensure safe equipment that is functional and can operate as designed when used in various combinations of wireless charging station. Today, we will be talking about the safety and security concerns of wireless charging that one must know and follow while using wireless charging solutions.

How Does Wireless Charging Work

Wireless charging is based on the magnetic resonance (MR) or inductive power transfer principle (IPT). Energy is transmitted from the charger to the device’s receiver via electromagnetic induction. Using an induction coil, the charger generates an alternating electromagnetic field, which the receiver coil converts back into electricity. Several wireless charging methods are:

Radio Charging: This method is commonly used to power devices with small batteries and low power consumption, such as smartphones, wireless mice, keyboards, medical devices, smartwatches, music players, and many others. The device’s receiver is set to the same frequency as the transmitter, allowing it to charge via radio waves.

Inductive charging: Inductive charging is a popular method for charging medium-sized gadgets. Inductive charging requires the device to be placed on a wireless or conductive charging pad before being plugged into an electrical outlet.

Resonance Charging: Resonant wireless chargers are utilized for high-power devices such as computers, electric cars, vacuum cleaners, and robots. The copper coil in the device is tailored to the same electromagnetic intensity as the coil in the power source during resonance charging.

Safety Concerns with Wireless Charging

Wireless charging technology has been hailed as a huge convenience, but it is important to consider the safety concerns associated with it as well. The primary safety concern with Wireless Charging is as follows:

Overheating of devices

One of the main safety concerns with wireless charging is that the device can overheat due to prolonged exposure to the electromagnetic field generated by the wireless charger. This can lead to an increased risk of fire or even permanent damage to the device. To avoid this, it is essential to make sure that the device is not left on the wireless charger for an extended period of time and that the charger is not overused. It is also critical to be aware of the device’s listed maximum charging temperature before charging.

Interference with other devices

Wireless charging works by creating a magnetic field, which can disrupt other nearby devices such as cell phones, laptops, and tablets. This interference can cause data loss, slow speeds, and other technical issues. To avoid interference, it is important to use the correct charger for the device and to keep other devices away from the charger when in use.

Potential for electrocution

One of the most significant concerns is the potential for electrocution. As with any device that uses electricity, there is always a risk of electric shock if the device is not properly installed or maintained. To prevent this, wireless charging units should always be installed and should be checked by a qualified electrician from time to time.

Effects on pacemakers and implanted medical devices

Wireless charging can potentially affect the functioning of pacemakers and other types of implanted medical devices. When wireless charging is used, it can create a magnetic field that could disrupt the functioning of these medical devices. To reduce the risk of any adverse effects of charging mobile security, it is important to keep any wireless charging devices at least 15 cm away from any implanted medical devices.


Ensuring Safe Wireless Charging

  • Using certified products that have passed strict, independent laboratory tests for safety, interoperability, and energy efficiency. Alternative claims such as “Qi compliant,” “Qi compatible,” or “Works with Qi” indicate that a product has not been subjected to proper Qi certification testing.
  • The charging pad should be placed on a flat, stable surface, away from any objects that could interfere with the charging, such as metal objects or magnets. The device should then be placed on the charging pad, with the back of the device facing down, and making sure that the device and charging pad are aligned properly.
  • To ensure safe and fast charging, remove any metal cases from the device before charging. Additionally, keep the device away from any metal objects and ensure that it is placed in an open, well-ventilated area.
  • One of the best ways to ensure safe wireless charging is to unplug the charging pad when it is not in use. This eliminates the risk of overcharging or overheating, as the charging pad will not be drawing any power from the outlet.


Future of Wireless Charging and its Safety

Wireless charging will be more accessible in public spaces like hotel rooms, on flights, and in lobbies. The business and commercial sectors are also introducing new and innovative wireless charger applications. Some potential applications of the wireless charging security include restaurant tables that charge mobile phones and other smart devices, office furniture with interconnected charging solutions, and kitchen counters that power the coffee machine and other appliances wirelessly.
