The article discusses the overall automotive voltage requirements of the 12-volt (V) systems and high-voltage hybrid vehicles. The increase of load requirements in vehicles have prompted to produce electrical power to run systems that were not present in past generations. With the addition of complex electronics into the battery system such as current measurement circuits and microcontrollers, its operation would greatly be enhanced. Details related to battery management of 12-V and hybrid battery to improve dependability and life span are discussed.
