Before we get to shred the tires in the totally kick-ass Ford Focus ST, we’ll get to hum around town in the Ford Focus Electric. The charged hatch will debut in the U.S. later this year, proving that Ford cares just as much about kicking fossil fuel as it does about destroying the track. At any rate, the little electric will use temperature-controlled lithium-ion batteries to push itself around. The new liquid temperature control system will keep the batteries at the optimum temperature, pumping warm liquid the batteries on chilly days and cooling them off when things warm up. The system even brings the batteries to the optimum temperature for charging. It’s a big deal—lithium-ion batteries are very sensitive to temperature. Get them too hot or too cold and you’ll lose capacity and power and possibly shorten their overall lifespan. The boffins at Ford say the system will drastically improve battery performance and overall lifespan.
