BATTERY PACK AND METHOD OF PROTECTING THE SAME
This abstract first appeared for US patent application 20250125637 titled 'BATTERY PACK AND METHOD OF PROTECTING THE SAME
Original Abstract Submitted
a battery pack includes battery cells between first and second pack terminals, balancing resistors respectively connected to the battery cells, balancing switches respectively connected to the battery cells and to the balancing resistors, and configured to form a closed circuit by connecting a corresponding one of the battery cells to a corresponding one of the balancing resistors, a rack fuse between the battery cells and the first pack terminal, or between the battery cells and the second pack terminal, a current sensor between the battery cells and the first pack terminal or the second pack terminal, and a controller configured to detect pack current between the first and second pack terminals through the current sensor, to control the balancing switches, and to detect a short-circuit between the first and second pack terminals based on the pack current and turn on all of the balancing switches.
