Title:
MANAGEMENT OF ELECTRICAL STORAGE CAPACITY OF BATTERY PACK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/094051
Kind Code:
A1
Abstract:
Managing battery cells in a battery pack circuit for reducing stored energy can include a plurality of battery packs electrically connected in a circuit in a battery system to provide a system output voltage. Each of the battery packs include a plurality of battery cells connected in an electrically conductive circuit, and each of the battery packs generate a pack output voltage collectively resulting in the system output voltage. In response to detecting when a cell of the plurality of battery cells of a battery pack of the battery packs approaches a threshold of a thermal state related to battery capacity, discharging electrical capacity of remaining cells in the battery pack thereby reducing available energy in the battery pack.
