The basis of the EV

08.10.2008

Today we’ll have a bit of theory. What are the basic elements of an electric vehicle (EV)? They are:

· batteries

· controller

· electric engine

If I have to compare the different parts of an EV and a normal petrol car, then the batteries of the EV should be the tank in the normal car. The energy is stored in the batteries and later it will be transformed in some kind of mechanical movement. The controller serves to command the electric engine. It determines the velocity of rotation of the electric motor. It has the same aim as the carburettor. It measures the fuel depending on the velocity we’d like to reach. In our case, the given fuel is the voltage of the batteries. The controller can perform other tasks just like the other controllers in the modern automobiles. The electric motor itself is simple If I have to be more specific, the electric motor has a moving part – a rotor and an immobile part – a stator. Just one electric motor has much less moving parts than an internal combustion engine. It has a bigger efficacy, but I’ll write about this in a separate post.

   Здравейте,
   имам една забележка към горната тема. В изречението: ” В нашия случай подаваното гориво е напрежението от батериите.” би трябвало ” напрежението” да се замени с “ток”, защото той ” двищението на електроните от – към + ” е физическия еквивалент на горивото на при двигателите с вътрешно горене. Иначе ви поздравявам за сайта и решмостта да се занимавате с електрически двигатели. Успех!
