Sensors Inside of Battery Cells

Access more energy from lithium ion batteries and increase their charge rate. Our disruptive technology has the potential to reduce battery costs considerably. More mileage in vehicles, smaller battery packs in power tools, a lower price for energy storage, and a secondary market for vehicle batteries make Insplorion’s battery sensor a potential game-changer for the green economy.

On-Board Sensors
Our sensors will improve battery performance and lifetime for on-board applications such as electric vehicles and industrial power tools. They will also enable a second-life market by providing information about battery health.
Quality Assurance & Control
For battery manufacturers, our sensor will aid in scaling up production, as well as in quality assurance and control, by assessing cell quality and performance at an early stage.
Stationary Energy Storage
Our sensors will enhance the performance and longevity of batteries in stationary energy storage systems. They will also enable evaluation of batteries previously used in other applications and make them available as lower-cost options for energy storage.
Research & Development
In research and development, our sensor will contribute to shortened development times and increased understanding of internal processes within the battery cell.

Improving Battery Monitoring

Insplorion’s battery sensor enables more effective use of batteries, resulting in increased accessible energy, reduced risk of explosion, and a longer battery life span.

This is made possible by measuring State of Charge (SoC), State of Health (SoH), and temperature from inside of the cell. Our disruptive technology can enhance state-of-the-art battery monitoring in unprecedented ways. Moving from non-precise estimations based on measuring voltage, current, and temperature externally, to precise measurements from within the cells, allows using up to 50% more of the available energy [1], and increases the charge rate with up to 23% [2] without running the risk of damaging the battery.

Improved battery status information also allows for an active aftermarket and more efficient use of nature’s resources.

Insplorion’s technology is currently available in commercially manufactured prototypes and can be scaled up to match the growing needs of electrified economies.
