As the automotive industry moves toward more electrification, the deployment of start-stop systems, eCall telematics, and hybrid vehicles is fueling the need for advanced battery management systems that charge the battery in a safe manner and prolong its useful life. This white paper explains Li-ion and LiFePO4 chemistries, including their characteristics and charging profiles. It also identifies charging solutions that derive the maximum energy from the battery while maximizing battery life and reliability.
