The Drive Module, a 100-percent aluminum chassis mounted under the Life Module, houses everything that makes the i3 go. It includes the 22-kilowatt, 450-pound lithium ion battery mounted as centrally as possible, and provides power to a rear-mounted electric motor that turns the rear wheels. With 170 horsepower and 184 pound-feet of torque from zero rpm, the single-gear i3 can accelerate from 0-30 miles per hour in 3.5 seconds and 0-60 mph in about 7.0 seconds, but it has a top speed of only 93 mph. BMW says the i3 has a real-world EV range of 80-100 miles, and the standard charger can fill the battery in three hours. Opt for the SAE DC Combo Fast Charger and 30 minutes is all it takes for a full charge; 20 minutes will bump the battery to 80 percent. For customers who have range anxiety, BMW gives them the option to install a 34-hp, 650cc two-cylinder generator as a range extender for the electric drive system.
Previously if we recall correctly BMW was going to move towards fuel cells.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Funny, I wouldn’t expect to see a battery rated in Kilowatts. All that would tell me is, perhaps, how quickly it could deliver energy to the motor.
I think people (at least those who understand how to measure electrical energy, anyway) would be more interested in knowing the energy capacity of the battery.
Kilowatt-hours is the dimensionally correct unit for that, as would be Joules.
Capacity can be inferred from an Amp-hour rating if the battery voltage is known.
I wish people would be more careful with things like that. I certainly didn’t expect that kind of gaffe from BMW.
