The idea of ​​using electric energy to move vehicles is not new, it arose as soon as the first electric motors began to operate, batteries having been discovered before. As early as the 1840s, prototypes of railway vehicles (Edinburgh, 1842) and boats (Saint Petersburg, 1834) were propelled by electromagnetic motors powered by batteries.

At the end of the last century, several electric cars powered, this time by electrochemical accumulators were produced. At that time when heat engines were far from the current stage, it seemed that electric propulsion had its chances, we know the rest. Note however the honorable performance achieved by all these prototypes, so the famous “Jamais Contente” (Figure 1.1) had driven 105 km / h in 1899 and, in 1901, a journey of 307 km without recharging had been achieved [1].
