BATTERY SYSTEM COMPRISING FIRST AND SECOND BATTERY CELL UNITS AND METHOD FOR CHARGING AND HEATING SAID BATTERY SYSTEM

Patentradars sammanfattning

Scania CV AB discloses a battery system with at least two battery cell units, each equipped with an individual current regulator arrangement, governed by a shared control arrangement. The control arrangement simultaneously directs conventional charging current to the first battery cell unit while applying high-frequency pulsed current (preferably 10 Hz–100 kHz) to the second, inducing Joule heating without triggering electrochemical reactions that would constitute charging or cause degradation. A decision layer based on measured or inferred resistance, temperature, state-of-health, and state-of-charge data selects which unit to charge and which to heat, and DC-DC converters independently regulate current/voltage to each unit. The architecture is targeted at electrified heavy-duty vehicles and generator sets requiring fast, service-life-preserving charging in cold environments.
