BMW’s EV Wireless Charging

BMW’s Wireless Charging

The new BMW 5-Series iPerformance models boast some very cool ‘world-first’ technology.  Available factory-fitted with a fully integrated inductive charging facility means that you can arrive home, park over a ground pad (the inductive charging facility/station) and hey-presto your car charges up, ready for your next trip away.

BMW’s Wireless Charging consists of the GroundPad (an inductive charging station), that can be installed either in a garage or outdoors, and the CarPad, which is fixed to the underside of the vehicle will connect to the GroundPad once parked appropriately.  This technology is available as an option on the new BMW 530e iPerformance model.  The GroundPad generates a magnetic field that induces an electric current in the CarPad, which then charges the battery in the car.

BMW’s 530e iPerformance model has the parking systems that help the driver to manoeuvre into the correct parking position over the GroundPad using a WiFi connection between the charging station and the vehicle.  Once the connection has been made, an overhead view of the car and its surroundings then appears in the car’s display screen with coloured lines that help guide the driver into position.  An icon shows up on the screen when the correct parking position is reached for the process of inductive charging.  BMW say the position for parking over the top of the GroundPad isn’t difficult to locate as the position can deviate by up to 7 cm longitudinally and up to 14 cm laterally – so it has plenty of buffering for getting a good connection.  To easy!

We already are becoming familiar with the wireless charging systems inside many new cars from different manufacturers where mobile phones and electric toothbrushes can be wirelessly charged inside the car.  BMW says its wireless charging uses the same inductive charging technology already widely used for supplying power to devices such as these.

BMW has unveiled a wireless charging system that will be available in Germany, followed shortly by the UK, the US, Japan and China.  It’s nice to be able to boast this technology and do away with cords and manual contraptions for charging your hybrid.  Germany and Europe seem to be leading the way with cutting edge EV technology, and this inductive charging system, created by BMW, will set the ball rolling for other manufacturers to follow suit.

I can imagine, like BMW, a world where you just pull up to your car park in the city, and the wireless inductive charging facility that’s set in place, in the road, underneath your EV will charge up your car while you duck into the café for a coffee or buy the necessary office equipment for your business.  This is all pretty cool technology!
