Solar energy system includes energy conversion from solar power to electricity, battery charging, and the use of energy for vehicle driving.
Hyundai Motor Group’s solar energy system lowers the load of the alternator which is a generator of the internal combustion engine and also charges battery of environmentally-friendly electric vehicles.
The solar energy system significantly improves the fuel efficiency and procure CO₂ credit as well.

Next-gen High-Efficiency Energy Conversion Materials
Thermoelectric conversion is a process in which thermal energy is directly converted into electric energy for thermoelectric power generation, or the other way around for thermoelectric cooling/heating.
Thermoelectric power generation is based on the principle in which thermal energy is transferred from a hot place to a colder place while accompanying negative electrons and positive holes of semiconductors, thus generating electric power.
The principle is used to convert the waste heat from the exhaust gas of combustion engine into electricity, resulting in reduced mechanical load of the alternator and less fuel consumption.
This, in turn, leads to a higher mileage and less CO₂ gas emission of vehicles.
Thermoelectric cooling/heating is an environmentally friendly technology in which electric current produces temperature gradient, so that one side is heated up while the other is cooled down.
The technology provides cooling and heating at the same time without any refrigerant and noise, being applied to the auxiliary air-conditioning for cabin comfort as well as the controlling temperature of automotive parts.
