IN THE WORLD OF MOTORS
Heading materials prepared by Mikhail GZOVSKY
Ford is one of the companies striving to introduce cars with alternative energy sources into mass production. As soon as one prototype leaves the laboratory of the company, it becomes known about work on the next. The company recently announced that in 2003 the Escape all-terrain vehicle with a six-cylinder gasoline engine paired with an electric will go into the series. Ford is confident that the hybrid Escape will be the most economical and environmentally friendly all-terrain vehicle in the world. And now the next promising car is ready, this time a completely different class - an electric car based on the baby "Ka".
“E-KA”, so called the new product, is interesting primarily for the type of battery. The creators of the machine from the Ford Research Center in Aachen (Germany) decided to demonstrate the advantages of lithium-ion batteries using the e-Ka example. First of all, they are distinguished by a high energy density, as well as the absence of a "memory effect", which is characteristic, for example, for nickel cadmium ones. (This effect is familiar to the owners of cell phones and camcorders: if you regularly charge an undercharged handset or camera battery, then it will run out much faster.) 180 e-Ka batteries are packed in three blocks and weigh 280 kg, which is three times lighter than traditional Lead similar capacity. The blocks are located in the engine compartment and under the floor on both sides of the rear axle.
On a long trip to
“E-Ka”, of course, you won’t go, because the range of the “electrical appliance” at a speed of 80 km / h is limited to 200 km. When driving at a maximum of 130 km / h, the need to refuel will arise even earlier. And this despite the machine weight and tricks reduced by 45 kg, designed to save energy in any way. Even the power steering (of course, electric) here consumes it only at the moment of turning the wheels, and not constantly, as in hydraulic boosters.
