Problems solved by technology
[0020] The main disadvantage of the second group of piezoelectric generators is that, due to the use of piezoelectric rods, the applied force causes the rods to twist, resulting in a gradual increase in force, so the current generated by the set piezoelectric components is undesirably for low
Therefore, the piezoelectric generators used in vehicles etc. in the prior art can only be used as an additional energy source to partially move the vehicles etc.

A piezoelectric generator system (100) comprises at least one piezoelectric generator unit (650) comprising an array (400) of piezoelectric modules (Mji,i) each including a piezoelectric element (Eji,i) and a AC / DC converter (Cji,i). The piezoelectric modules (Mji,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 (F1, F2.. Fn) act on the piezoelectric generator units (650), said loads (F1, F2.. Fn) are adjusted such that a predetermined amount of force (F) is applied with a predetermined speed to the piezoelectric modules (Mji,i), such that the array (400) supplies high electric power (Pout-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.
Description
[0001] This application claims the benefit of European Patent Application EP 15382601.1 filed on December 2, 2015. [0002] The present disclosure relates to piezoelectric generator systems and electrical systems including such piezoelectric generator systems. Background technique [0003] The continuous increase in global energy demand is one of the most important problems that exist today, causing energy scarcity, polluting energy use, impacts on climate change, disease, shortened life expectancy, poverty, hunger, and wars for energy control. [0004] This has attracted considerable attention in recent years, and alternatives to polluting energy sources have been proposed, such as renewable and sustainable energies. However, they do not provide enough energy to cope with the increased energy demand, so said non-environmentally friendly energy sources are still used in large quantities. [0005] Clean energy sources such as hydro or eolic power plants require a large amount ...
