  • Publication number: 20230170728
    Abstract: An emergency call (E-call) system may execute control such that an E-call battery operates in a 1 series 1 parallel (1S1P) mode or a 1 series 2 parallel (1S2P) mode depending on the temperature of a usage environment of the E-call battery to improve the discharge performance of the E-call battery in a low-temperature environment. A method for controlling an operation of the E-call system is also disclosed.
