Technology Description:

Lawrence Livermore National Laboratory (LLNL) is developing a wireless sensor system to improve the safety and reliability of lithium-ion (Li-Ion) battery systems by monitoring key operating parameters of Li-Ion cells and battery packs. This system can be used to control battery operation and provide early indicators of battery failure. LLNL's design will monitor every cell within a large Li-Ion battery pack without the need for large bundles of cables to carry sensor signals to the battery management system. This wireless sensor network will dramatically reduce system cost, improve operational performance, and detect battery pack failures in real time, enabling a path to cheaper, better, and safer large-scale batteries.

Potential Impact:

If successful, LLNL's wireless sensor network for large Li-Ion battery packs would improve the safety and reliability of electric energy storage systems.

Security:

Advances in energy storage management could reduce the cost and increase the adoption of electric vehicles and renewable energy storage technologies, which in turn would reduce our nation's dependence on foreign sources of energy.

Environment:

Improving the reliability and safety of electric vehicles and renewable energy storage facilities would enable more widespread use of these technologies, resulting in a substantial reduction in carbon dioxide emissions.

Economy:

Enabling alternatives to conventional sources of energy could insulate consumers, businesses, and utilities from unexpected price swings.
