Self-repairing cells improve battery life and EV performance
December 07, 2021
New technology from StoreDot, a developer of extreme fast charging battery technology for electric vehicles (EVs), will allow battery cells to regenerate while in use through a seamless background repair mechanism.
The self-repairing system includes a suite of software algorithms with corresponding hardware to identify a cell or string of cells that are underperforming or overheating. The targeted components are temporarily disabled in order to proactively recondition them back to 100% performance, without the operator experiencing any driving interruption or loss of EV performance. This advancement of a 'self-healing' approach for EVs will play a major role in prolonging battery life and driving range, as well as improving safety by preventing overheating or any danger of thermal runaway.
A recently granted patent
, 'Recovering defective branches and/or cells of battery packs by deep discharges,' details how this innovation should be implemented in various EV battery pack scenarios, while the vehicle is either charging, resting or driving.

The Israel-based company has also been granted patents for technologies that deliver a constant range throughout the life of an EV as the battery deteriorates. It has also made available, through open-source, hardware, and software advancements of a booster technology that allows cells to receive a higher charging current, giving faster charging times even in limited charging infrastructure scenarios.
