More Information
Summary:The piezoelectric generator system (100) comprises at least one piezoelectric generator unit (650) comprising an array (400) of piezoelectric modules (M ji,i ) each including a piezoelectric element (E ji,i ) and a AC/DC converter (C ji,i ). The piezoelectric modules (M ji,i ) in the array (400) are connected to each other in series and they are each arranged in sets (i) connected to each other in parallel. When dynamic loads (F 1 , F 2 .. F n ) act on the piezoelectric generator units (650), said loads (F 1 , F 2 .. F n ) are adjusted such that a predetermined amount of force (F) is applied with a predetermined speed to the piezoelectric modules (M ji,i ), such that the array (400) supplies high electric power (P out-tot ) to one or more batteries (250) in, for example, an electric vehicle (1000), with each battery (250) being capable of working in at least storage, standby and supply conditions according to the corresponding electric power level thereof.
