Patent number: 12334521Abstract: A device for enabling the reuse of a complete battery pack for electric vehicles (EV) is disclosed. The device allows reuse of a battery pack at a significantly lower cost than alternative methods that require the battery pack to be opened, batteries to be taken out and installed in a new pack with a new battery monitoring system (BMS), and undergoing certification as a new system. The disclosed device includes a controller having a software program operating therein and which is electrically coupled to a battery pack and provides electrical input and output signals to the BMS of the EV battery, which relate to optimal operating parameters of the battery pack including depth of discharge (DoD), depth of charge (DoC), charge rate, and temperature. The controller enables reuse of the complete battery pack without reopening and mimics electrical signaling compared to a car or other electric vehicles.Type: GrantFiled: January 20, 2022Date of Patent: June 17, 2025Assignee: ECO STOR ASInventor: Trygve Burchardt

Publication number: 20250172631Abstract: Understanding a health status and expected remaining lifetime of an EV (electric vehicle) battery is important before repurposing the battery for second life applications. A device for connecting to an unopened EV battery pack via operable coupling to signal and power wiring is disclosed. The device enables access to diagnostic information from the unopened EV battery. The device measures cell and/or module voltages and currents within the battery pack for several different depths of discharge. A self-learning algorithm implemented by the diagnostic device, which uses historical data and diagnostic information from the battery pack, determines a condition of the battery and provide recommended operational conditions for future use of the battery. For example, a degradation slope and expected capacity loss over time can be determined based on measured variations of cell and/or modular voltages and subsequently used, with cell impedance data, to recommend an operational C-rate for the battery pack.Type: ApplicationFiled: January 27, 2025Publication date: May 29, 2025Inventor: Trygve Burchardt
