Exro Technology

Battery Control System™

An innovative battery control solution, extending batteries into a second life.

The battery cells in an electric vehicle reach end of life within 8-12 years, depending on battery conditions. These batteries can be optimized and repurposed into a second life with Exro's Energy Storage System (ESS) that is equipped with our Battery Control System™ (BCS).

Exro’s BCS is an innovative battery management inverter combined with an advanced cell control software that can expand the capabilities of batteries by enabling a greater depth of control on the cells. Our technology not only repurposes batteries into an ESS, but it can also be utilized as an effective solution for first life applications.

Optimizing and Extending Battery Capabilities

Exro 90kW/192kWh Energy Storage System (ESS). Concept design Exro ESS, sizes are not to scale.

Second Life Energy Storage

As more electric vehicles reach end of first life, there is a growing number of batteries that can be utilized for second life energy storage. The Battery Control System™ can lead the rapidly growing energy storage markets by extending battery life, increasing reliability, and reducing total costs.

Next-Gen Cell Control Solution

Exro’s proprietary Battery Control System™ controls the charging and discharging based on state-of-charge (SOC) and State-of-Heath (SOH). Considering the enhanced depth of control, the solution is optimized for maximum cell lifetime while enabling micro-protection mechanisms for improved safety and uninterrupted operation.
