Technology to Increase Energy Density of Electric Car Batteries

Abstract

The article deals with a small-sized unit developed using ferro-piezoelectric ceramics for electric power generation. The use of an electrochemical generator in the unit makes it possible to increase the efficiency of electricity generation by controlling the polarization of ferro-piezoelectric ceramics. At the consumption of 1 joule of electricity, using mechanical energy, 3, 5...5 joules of output electrical energy are generated. The increase in the energy density of the batteries occurs in two stages: the first stage is to increase the degree of polarization of the segmentelectric, the second stage is to increase the electrical power to the load. The power plant efficiency is about 55...60 percent and depends on the ceramic modification and the electric circuit.
