The use of electricity to boost our car or our bicycle, although it is becoming widespread, is still something unusual, almost exotic. However, at the dawn of the 20th century, electric vehicles were very common.
At that time, steam, gasoline and electricity competed for automotive supremacy and did it almost at the same level, because electric cars were much simpler and more reliable, as well as silent and less polluting. In Chicago, for example, the electric car dominated the automobile industry.
In 1839, Robert Anderson invented what would be the first electric "car" in history. Actually it was a carriage equipped with an electric motor, which reached 6 km / h. In 1906 the "Association of Manufacturers of Electric Vehicles" was created. In 1911, Thomas Edison introduced new models of rechargeable nickel-iron batteries, which allowed reasonable autonomy for the time and speeds of up to 130 km / h. Y 1912 was probably the year of the electric car: in the streets of the United States there were more than 30,000, and another 4,000 circulated in Europe. In 1918, one fifth of all Berlin taxis were electric.
The disadvantage that begins to be advantageFlocken Elektrowagen (1888) considered the first electric manufacturing car.
So? Why was the gasoline engine imposed? Why aren't all roads in the world dominated by electric vehicles? The main reason is that electric vehicles must be charged with their own batteries, that they are not capable of storing large amounts of energy and that, once used up, require a lot of time to recharge.
The autonomy of those first electric cars was 150 kilometers, like a modern electric car. The difference is that those cars were very light and could barely carry cargo. A ballast that was not such for a gasoline engine, and therefore the balance leaned towards combustion engines. Currently electric cars are larger and can carry more weight, so the autonomy has been maintained in those 150 kilometers.
However, the tables seem to be changing little by little, as we talked a few days ago about the new batteries that will double their autonomy. Thus, by 2025 it is expected that approximately 15% of all new cars built in the world will incorporate at least one hybrid propulsion system. In Europe, more than a third of all new cars will be electrically powered.
In an RACC test track we had the opportunity to test an electric car and an electric bicycle. Specifically, we were invited to the RACC Safe Driving School, in Moraleja de Enmedio, Madrid, where we were introduced to the business area Bosch Mobility Solutions: automation, electrification and mobility connectivity.
Then you can see me testing an eBike with Bosch drive, which is integrated into many of the major brands of eBikes. The drive unit provides a dynamic, noticeable but homogeneous thrust thanks to the system taking measurements 1,000 times per second. From moderate assistance to maximum power, pedaling like this is a joy. For legal reasons, you cannot exceed 25 km / h, and if you do, the drive is deactivated and you only depend on the muscles of your legs.
The available lithium batteries are the Power Pack 300 (36V 8.2Ah = 300 Wh) and the Power Pack 400 (36V 11Ah = 400 Wh). The latter is able to provide you with more than 180 kilometers of maximum autonomy in ideal conditions and in applying the smallest assistance. There comes a time that you almost feel in a Deorean when he falls the lightning bolt and, zas, you travel in time: at the dawn of the 20th century, and also in the middle of the 21st century.
