Abstract

An automotive battery system including a first battery that couples to an electrical system. Additionally, the first battery includes a first battery chemistry. Further, the automotive battery system includes a second battery coupled in parallel with the first battery and couples to the electrical system. Furthermore, the automotive battery system includes a first switch coupled to a positive terminal of the second battery, which electrically couples or decouples the second battery to or from the electrical system. Moreover, the automotive battery system includes a battery control unit that detects a short circuit condition of the first battery, the second battery, or both and decouples the second battery from the electrical system by opening the first switch upon detecting the short circuit condition.
