There is the possibility to replace this chemistry with a Li-ion technology in hybrid vehicles, due to its potential beneficial features. Besides, there is a need of an extremely reliable 12V electric system in hybrid cars, not only for the current electric distribution system in the car, but also due to the introduction of autonomous drive. Moreover, since packaging space is a big issue in modern cars there is also a need to reduce the number of components. Therefore, it is important to study the impact when integrating the 12V Li-ion battery to be a part of the electric system as a power source, including the power distribution system and loads, in order to improve the utilization and performance of the battery.
