According to foreign media reports, a team of researchers from the University of Palermo and ICAR developed an electric kinetic energy recovery system (e-KERS) for internal combustion engine vehicles (ICEV), which uses super capacitors as Energy storage equipment can be connected to a brushless motor through a power converter.
The researchers said that the system can save 20% of the energy, and only slightly increase the weight of the vehicle (2%). Due to improved fuel economy and reduced carbon dioxide emissions, it can offset the total commercial cost of the system within 5 years.
The researchers believe that the system has low complexity, the weight of the components is moderate, and such components are available on the market, so the solution is suitable for introduction into current automobile production.
The only kinetic energy recovery system (KERS) currently being developed for internal combustion engine vehicles is KERS controlled by an alternator, and some car manufacturers (such as BMW Efficient Dynamics) have brought it to market. In this type of system, when the vehicle brakes, the output of the alternator will increase, and then part of the kinetic energy of the vehicle will be transferred to the battery. The energy of the battery is used to power the electronic consumer products of the car, which ultimately reduces the alternator. Electricity absorbed while the vehicle is running. The advantage of this type of system is that it can be directly introduced into the current ICEV production process. However, because its components are not dedicated and not optimized for KERS applications, the improvement in fuel economy is very limited, generally only 1% to 5%.
This time, the researchers proposed an electric KERS (e-KERS) for internal combustion engine vehicles, which consists of a super capacitor, a motor generator assembly (MGU) and a power converter. The supercapacitor is used as an energy storage system. The motor generator assembly can convert the kinetic energy of the vehicle into electrical energy (or vice versa), and the task of the power converter is to manage the energy transfer between the supercapacitor and the motor generator assembly. The system charges the supercapacitor to recover the kinetic energy generated when the vehicle brakes, and then the energy stored in the supercapacitor will be used by the motor generator assembly for the vehicle and then accelerated.
The supercapacitor is electronically connected to the motor generator assembly through a designed power converter. The motor generator assembly is mechanically connected to the drive shaft through a fixed transmission shaft ratio, which converts the kinetic energy of the vehicle into electrical energy and vice versa.
