Energiavisszaadás

Energiavisszaadás, also known as energy recovery or regenerative braking, is a technology that captures and reuses energy that would otherwise be lost during a process. This is most commonly associated with electric vehicles and trains, where it is used to slow down the vehicle by converting kinetic energy back into electrical energy. This electrical energy is then stored in a battery or supercapacitor for later use.

The principle behind energy recovery is based on Faraday's law of induction. When an electric motor is used in reverse, it acts as a generator. As the vehicle decelerates, the motor spins, generating electricity. This process not only helps to slow the vehicle down but also reduces the wear on traditional friction brakes.

In industrial applications, energy recovery systems can be found in various processes such as ventilation, heating, and cooling. For example, in a building's ventilation system, heat from the outgoing air can be used to preheat the incoming fresh air, thus reducing the energy required for heating. Similarly, in manufacturing, waste heat from one process can be used to power another.

The benefits of energy recovery include reduced energy consumption, lower operating costs, and decreased environmental impact due to lower emissions. It is a key component in improving the efficiency of many modern technologies and industrial processes, contributing to sustainability efforts.
