BMW's ActiveAssist collision avoidance system and EV's Inductive charging - 2015 CES LIVE video
The company challenged CES attendees to crash an i3 equipped with BMW's ActiveAssist collision avoidance system dotted with concealed external laser sensors.
Unlike traditional ultrasonic parking sensors, the ActiveAssist system pinpoints obstacles and collision risks and makes the car react accordingly.
Inductive charging re-energizes an EV's battery with a magnetic field rather than a wire from car to power source.
It's achieved by fitting a primary coil in a floor-plate over which a car can park and a secondary coil on the underside of the car itself.
An alternating magnetic field is generated between the two coils, which creates electricity that is then sent to the BMW's on-board battery.
At a charge rate of 3.3 kW, the battery of a BMW i8 can be charged in under two hours, which is about the same amount of time as it takes the current wired recharger.
Down the line, a 7kW rate will be able to charge the larger batteries of an all-electric vehicle, like the i3, overnight
