In-Cabin Wireless
Charging Solutions
for Automotive &
Transportation

Powermat’s in-car wireless charging technology meets the Qi®15w extended power protocol specification and supports Apple & Samsung’s fast charge protocols. Powermat’s unique system architecture provides higher efficiency than competing solutions in the market, enabling faster charging for a more extended period.

Yes. Powermat’s in-car wireless charging technology for automotive and transportation offers NFC & CAN Integration, including NFC card protection, Bluetooth, and Wi-Fi pairing & personalization settings. Powermat also offers pre & post-production system upgrades and ongoing support from our team of specialists.

Powermat’s automotive platform can be ported to any standard automotive-grade microcontroller to implement the wireless charging function and our firmware that controls all aspects of the charging. By doing this, we allow maximal flexibility and the ability to tune the design and provide software upgrades.

Powermat’s In-car wireless charging technology is an embedded component installed inside cars that can charge smartphones, wearables, and any Qi-enabled device wirelessly. Powermat also supports Apple and Samsung Fast Charge protocols.

Powermat’s wireless charging technology for automotive in-cabin integration offers automotive in-cabin systems for passenger vehicles, commercial vehicles, two-wheelers, public transportation, marine & boating, and aviation.

Powermat’s in-car wireless charging technology comes with our unique SmartInductive™ approach that provides up to 66% more range per coil and is available in single/multi-coil designs along with a significantly large active area, allowing flexibility and freedom of positioning.

The optimal recommended distance heavily depends on the specific design. However, a 2.5mm gap from coil-to-coil would seem to provide a good trade-off. With proper thermal isolation, it would allow keeping some airflow below the device needing power while keeping a close enough distance to avoid stressing the transmitter (Tx).

The most critical issue in wireless charging technology is finding the ideal way to cool off the handset. The transmitter can use passive cooling even for a 15W design as it may operate at high temperatures. Still, it is crucial to ensure that the surface temperature can evacuate heat from the phone itself.

Smartphone charging speed is mainly affected by the internal battery temperature. Internal battery temperature is a crucial factor for the charging rate. Most handset manufacturers use throttling for charge rates with threshold temperatures in the range of 37-40 degrees.

The Qi standard focuses on protocol compatibility to enable certified devices compatibility & interoperability and safety functions such as y FOD (Foreign Object Detection) and authentication.

Yes. Samsung and Apple both use proprietary extensions on top of the standard Qi BPP protocol. The extensions are known and are implemented by all Powermat designs. The charger recognizes the specific phone brand and uses the required extension to operate in fast charge mode with these handsets. It should be noted that there are many delicate details to the correct and safe implementation of fast charging.

As wireless charging continues to be an inherent part of the automotive in-cabin experience, its physical presence in the car as a charging “nest” for Smartphones becomes the ideal touchpoint for charging personal devices and also enable fast, secure, and authenticated connectivity features between the driver (or the passenger) and the vehicle. Powermat’s wireless charging platform for vehicle in-cabin applications comes with an optional NFC connectivity layer. Powermat’s NFC connectivity layer provides NFC card protection and enables connectivity features such as Driver or passenger authentication, personalization, and fast Bluetooth or Wi-Fi pairing.
