Coil Driver™

Coil Driver™ is the most intelligent motor controller, optimizing electric motor performance and efficiency via direct control of the motor coil windings. Depending on load and application demand at any given time, Coil Driver™ is designed to switch motor configurations between series and parallel modes on the fly, without any disruption in motor operation.

Energy Storage System

Exro’s intelligent Energy Storage System that is equipped with it's proprietary Battery Control System™ (BCS) uses cell-level control mechanisms. This introduces the next generation of energy storage solutions that can extend the life of retired electric vehicle batteries and repurpose those cells for stationary energy storage applications.

Energy Storage System

Optimized for the Present.
Extended for the Future.

In traditional lifecycles, second life energy requires tear down, testing, and certification, which can be complicated by varying battery cell chemistries and forms. In an Exro lifecycle, our class of control technology expands the capabilities of any electric motor, generator, and battery, achieving more with less energy consumed.

The Exro Difference

Switching automatically and seamlessly, Coil Driver™ selects the appropriate torque profile to optimize the current torque and speed demand. Unlike standard inverters, Coil Driver™ achieves 100% utilization of DC link voltage in both its series and parallel modes. This significantly extends the capabilities of the electric motor, leading to:

  • Starting torque increase
  • Overall torque output improvement across the speed spectrum
  • Enhanced power across the speed spectrum
  • Reduced mechanical loss and total cost of ownership
Legend indicates blue line on graph represents Exro Coil Driver and grey line is Industry Standard.
Line graph shows Exro Coil Driver has 60% performance improvement compared to industry standard.Line graph shows Exro Coil Driver has 150% performance improvement compared to industry standard.
Performance curves are based on a system comprised of Exro 800 Coil Driver™ and TSA TMPW 38-26-8 motor.
