Kia targets 15% CO2 reduction for new mild hybrid system
Developed in Germany, the system comprises a 48-volt lead-carbon battery and motor-generator, the latter offering regenerative braking while decelerating, functioning as the engine starter and alternator and providing power while cruising or at low speeds.
Kia said lead-carbon batteries are being used as they require no active cooling, function more efficiently in sub-zero temperatures and can be recycled more easily at the end of the vehicle’s life cycle.
In more powerful applications the system can also be equipped with an electric supercharger to increase torque and power at low engine speeds, assisting a larger turbocharger for higher revolutions.
Kia said the system will be fitted to new diesel and production cars in the near future.
