It takes 3.5 hours to charge the 530e's battery pack without a cord.

The plug-in hybrid BMW 530e will soon be available with wireless charging technology. The Munich-based company has released a short video to highlight how it works.

The system's main components are two coils; the first is bolted under the car's body and linked to the battery pack, while the second is attached to the user's garage floor and hooked up to a power supply. Lines that show up on the car's infotainment screen help the driver position the top coil right over the bottom one.

Charging begins automatically as soon as the car is positioned correctly, and the engine is turned off. The inductive charger tops up the 530e's 9.2-kWh battery pack in about three and a half hours, which makes it a little bit slower than the regular charger. A smartphone application lets users remotely monitor the charging process.

Owners can drive the 5 Series for up to 16 miles on a full charge, which is enough to navigate through many urban centers in zero-emissions mode. BMW expects the wireless charging option will be a popular one because it makes the charging cord an item of the past.

Wireless charging will be available on the 2018 530e. It will be offered at an extra cost, but BMW hasn't released pricing information yet. Other plug-in hybrid members of the BMW lineup -- like the 740e and the 330e -- are expected to receive the technology in the not-too-distant future.
