Latest Patents

One of John C Hewson's latest patents is titled "Dispersion of stored energy within a battery system at risk of failure." This invention presents a method and system for dispersing stored energy in an energy storage system to delay or arrest the propagation of thermal runaway and thermally-induced cascading failures. The system comprises a plurality of battery sub-assemblies and DC-DC converters connected to a shared DC bus, allowing for energy exchange. It can interface with an AC power grid or DC power system through an additional power converter. The method utilizes this system to charge and discharge sub-assemblies, making it less susceptible to thermal runaway. It determines the sequence of charging and discharging actions based on the current system state, battery types, and electrical and thermal structure, thereby inhibiting thermal runaway while preserving the system's ability to perform subsequent energy redistribution.
