The invention discloses a piezoelectric transducer for road and a power generation characteristic test device and an energy storage experiment device thereof. The piezoelectric transducer for road includes a positive wire, a negative wire, a plurality of first conductive substrates and a plurality of second conductive substrates. The first conductive substrates and the second conductive substratesare in cross distribution in sequence from top to bottom. A plurality of piezoelectric vibrators are arranged between each first conductive substrate and the second conductive substrate adjacent to the first conductive substrate. The positive electrode of each piezoelectric vibrator is in contact with the corresponding first conductive substrate, and the negative electrode of each piezoelectric vibrator is in contact with the corresponding second conductive substrate. The positive wire is connected with the first conductive substrates, and the negative wire is connected with the second conductive substrates. The piezoelectric vibrators are prepared from PZT and PVDF. The piezoelectric transducer has good bearing capacity, power generation performance and durability. The test device can detect the power generation characteristic of the piezoelectric transducer for road. The experiment device can simulate the power generation and energy storage of the piezoelectric transducer for road.
