摘要： Systems for suppressing adverse exothermic reactions in an energy storage container. One energy storage system includes a container configured to support a plurality of battery cells; a plurality of battery cells disposed inside and supported by the container; an agent supply port attached to the container; and a tube disposed inside the container and having a closed end and an open end. The open end of the tube is in fluid communication with the agent supply port. The tube comprises fusible portions which are designed to melt or soften at a temperature which is lower than the melting or softening temperature of another portion of the tube. In response to melting or softening of the fusible portions of the tube, pressurized exothermic reaction-suppressing agent is distributed inside the container via the tube.

摘要： A battery and related methods are described. The battery can include a plurality of battery cell segments. Each of the battery cell segments can include an anode segment, a cathode segment, and one or more current limiters. The one or more current limiters are configured to conditionally electrically isolate the battery cell segment based on an occurrence of a short circuit within the battery cell segment. The battery can be used to store electrical power and/or provide electrical power to a load.

摘要： A reconfigurable battery system is disclosed. The reconfigurable battery system comprises a reconfigurable battery cell array, a controller, and a bus switch. The battery cell array is configured to operate in a first discharge mode, a second discharge mode, or a charge mode. The battery cell array includes a plurality of battery cells arranged as at least a first column of battery cells between a second battery terminal and a first battery terminal and a switch between each battery cell within the first column of battery cells. The bus switch is in signal communication with the battery cell array at the first battery terminal and is configured to select between electrically connecting the first battery terminal to a normal voltage bus or a high-voltage bus.

摘要： System and method for allocating load power drawn from multiple batteries for powering propulsion of a vehicle. The system includes: high-energy and high-power batteries respectively designed for optimal production of DC power during high-specific-energy and high-specific-power propulsion; and battery health management systems configured to monitor state of charge and state of health of the batteries and generate battery status signals. The system further includes a propulsion load configured to produce propulsion force using power converted from power generated by at least one of the batteries and a system controller configured to allocate load power drawn from the high-energy and high-power batteries for use by the propulsion load in dependence on a propulsion phase of the vehicle and the battery status.

摘要： System and method for allocating load power drawn from multiple batteries for powering propulsion of a vehicle. The system includes: high-energy and high-power batteries (18a; 18b) respectively designed for optimal production of DC power during high-specific-energy and high-specific-power propulsion; and battery health management systems (16a; 16b) configured to monitor state of charge and state of health of the batteries (18a; 18b) and generate battery status signals. The system further includes a propulsion load (26a; 26b) configured to produce propulsion force using power converted from power generated by at least one of the batteries (18a; 18b) and a system controller (12) configured to allocate load power drawn from the high-energy and high-power batteries (18a; 18b) for use by the propulsion load (26a; 26b) in dependence on a propulsion phase of the vehicle and the battery status.
