Principle of operation

The electric motor is a “storage of energy”, which is transferred to it from the internal combustion engine when the car is idling, or the full potential of the power unit is not used. Thanks to this, unspent energy accumulates and allows you to move around on an electric motor, which is a large battery with the ability to recharge. The accumulated energy is released when the on-board computer determines the right moment.
