Cell Driver™

Commercial and Industrial energy storage solution with an innovative Battery Control System™

The Exro Cell Driver™ is a fully integrated system equipped with our proprietary Battery Control System™ (BCS). The BCS actively balances the charging and discharging, enables a higher depth of control on the cells, enhances safety, and intelligently isolates faults to ensure continuous power delivery while matching power quality.

The Cell Driver™ is also an optimal solution for second-life EV batteries as the BCS technology estimates State-of-Charge and State-of-Health of battery cells starting in the commissioning process. Substantially reducing the emissions and the need for raw earth materials by almost doubling the lifetime of retired EV batteries.

Enhanced Safety: Dynamic micro-protection mechanisms with functions for current, temperature, and voltage. Electrically isolate defected cells without disruptions to system operation.

Decreased Total Cost of Ownership: Fault isolation minimizes down time and prevents disruptions in power delivery. Cell Driver™ also offers shortened installation and maintenance time using modular plug-in design.

Optimizing and Extending Battery Capabilities

Exro Cell Driver™ 90kW/192kWh: Commercial and Industrial Energy Storage

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). Active cell balancing enables enhanced depth of control, maximized cell lifetime, and micro-protection mechanisms for improved safety and uninterrupted operation.

Second Life Energy Storage

The battery cells in an electric vehicle reach end of life in about 8-12 years, depending on battery conditions. 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 Cell Driver™ can utilize retired EV batteries and give them a second life in energy storage applications, significantly reducing total cost of ownership with enhanced reliability and safety.
