  • FAST CHARGING BATTERIES AT LOW TEMPERATURES WITH BATTERY PACK PREHEATING
    Publication number: 20230361366
    Abstract: A method and apparatus for charging a battery pack including a plurality of electrochemical cells distributed within a thermal management composite matrix, including a phase change material. The method operates upon determining that a battery pack temperature and/or voltage measurement is below a predetermined minimum threshold. The pack temperature and/or the voltage measurement is raised to the predetermined minimum threshold, such as by applying a low current rate, and then the charging rate is increased upon reaching the predetermined minimum threshold. The increased charging rate is further selected based upon a thermal state of charge of the thermal management composite matrix.
