100K OF CODE MAKES EV MOTORS MORE EFFICIENT – AUTOLINE EXCLUSIVES

EV Channels Review

Autoline Exclusives features Tula's innovative Dynamic Motor Drive (DMD) technology, a software-based solution designed to enhance electric motor efficiency. By pulsing electricity to the motor instead of a continuous flow, DMD reduces energy consumption, offering automakers the flexibility to either extend EV range or reduce battery size and cost. The technology, developed by a company with a proven track record in engine efficiency (Dynamic Skip Fire for GM), operates by pulsing at higher torques with lower relative losses, averaging out to the required lower torque with less overall energy. The system overlays a lower frequency pulsing strategy onto the vehicle's existing PWM control, requiring minimal additional computing power and memory (less than 100KB). Tula claims efficiency improvements of 0.3% to 2% on WLTP cycles, potentially translating to significant cost savings per vehicle. The company is licensing this technology competitively, positioning it as a cost-effective alternative to solutions like Silicon Carbide (SiC) and a strong enabler for wound rotor motors, reducing reliance on rare-earth magnets. Tula anticipates first production in China later this year, with ongoing engagement in Europe and the US.
