BMW is patenting new wireless charging technology that can be used with electric vehicles

BMW is patenting an innovative new technology that would charge electric motorcycles via their standards

  • BMW has applied for a new patent for a new way to charge electric motorcycles
  • The patent would use an AC coil in a motorcycle stand to draw electricity
  • A is placed as standard on a charging pad with an AC coil that is connected to a wall

BMW has filed a new patent that demonstrates an innovative approach to wireless charging for electric motorcycles.

In an illustration submitted to the depot, the German car manufacturer shows a standard for a charging station with an AC coil connected to a wall.

The standard has its own AC coil embedded in the tip, which converts electromagnetic current from the ground pad into electricity that is sent via a cable to the motor battery.

The patent application contains no information about how quickly the system could charge a battery, according to a report from Electrek.

Although wireless charging is a common feature in mobile phones, electric toothbrushes and video game controllers, it remained a challenge for electric vehicles because most vehicles have no conductive material that could come into direct contact with a charging station.

Last year, a wireless charging company, Momentum Dynamics, announced it would provide wireless charging stations for a small number of public buses in the state of Washington.

That technology would place large receiver blocks with copper wire in buses.

Those cushions would be charged when they rest in place above the electromagnetic field created by a similar cushion embedded in the sidewalk at targeted bus stops.

The company said that with five minutes of charging at a routine stopover, buses would receive enough electricity to complete an additional route, although the exact charging speeds were not shared at the time.

Usually, wireless charging speeds depend on the distance between the two coils, with speeds increasing the closer the two are.

In contrast to cars, motorcycles have a clear advantage with their conductive metal standards, which can easily be used to receive currents from a much shorter distance than receiver blocks under car-floor plates.

In 2018, Kia announced that it had developed a wireless charging station for its electric cars, but refused to release it to the public.

Viewers in the industry have speculated that one of the major obstacles to wireless charging is that the convenience of not connecting a car or motorcycle to the wall is not worth the significant increase in charging time.

HOW DOES WIRELESS CHARGING WORK?

Wireless charging as a concept has been around since Nikola Tesla, a Croatian inventor, first suggested in the 19th century that you could transfer energy between two objects via an electromagnetic field.

The charging station contains a loop of coiled wires around a bar magnet, also called an inductor.

When an electrical current flows from the net through the coiled wire, it creates an electromagnetic field around the magnet.

This can then be used to transfer a voltage – or charge – to the smartphone.

It is said that Apple is working on a charging system that works at 7.5 watts.

This means that it does not offer higher charging speeds than conventional chargers, which offer 15 watts as standard.

With a direct contact solution via a conductive standard, it is possible that the charging times are considerably faster than previous wireless charging solutions.

In 2016, BMW showed a number of other futuristic ideas with a concept-electric motorcycle, the Motorrad Vision Next 100, with gyroscopic sensors with which the motorcycle could always remain horizontal.

In 2017, it shared a similar experimental concept for an electric scooter that could automatically adjust the seat height for different riders.
