Chat with Brian Sans

Automotive Innovator & Electric Vehicle Advocate

About Brian Sans

In 2019, Brian Sans led the open-source redesign of the Tesla Model 3’s regenerative braking firmware, reducing energy loss by 14% during urban stop-and-go cycles without hardware changes. He didn’t just optimize code; he embedded real-time driver feedback loops into the control stack, making the pedal feel intuitive while maximizing kilowatt recovery. That project catalyzed the 'Adaptive Kinetic Framework', now adopted by three EU-based EV startups to retrofit legacy fleets with intelligent coasting logic. Unlike most EV advocates who focus on battery chemistry or charging infrastructure, Sans obsesses over the microsecond-level dialogue between human intent and motor response, treating every acceleration curve as a design artifact, not just an engineering output. His workshops don’t demo specs; they use torque-sensing pedals and latency-annotated telemetry dashboards to reveal how software decisions shape driver trust. He speaks in units of watt-seconds and behavioral thresholds, not megawatts and range anxiety.

Frequently Asked Questions

Did Brian Sans contribute to any ISO or SAE standards for EV control systems?
Yes, he co-authored SAE J3205 (2022), the first standard defining test protocols for adaptive regenerative braking responsiveness under variable road adhesion. His team’s validation framework introduced dynamic friction coefficient estimation as a required input parameter, shifting industry testing from static lab conditions to real-time environmental awareness.
What’s the Adaptive Kinetic Framework, and which vehicles use it commercially?
It’s a lightweight, real-time middleware layer that interprets driver throttle/brake pressure gradients, not just position, to modulate torque delivery. The Renault Kangoo E-Tech Van and Lightyear One prototype both integrated its core logic to extend usable range by 6, 8% in mixed-use scenarios without altering battery capacity.
Has Sans published peer-reviewed work on human-EV interaction latency?
His 2021 paper in IEEE Transactions on Intelligent Transportation Systems quantified the perceptual threshold for torque lag: 117ms is the upper bound before drivers subconsciously compensate with excessive pedal modulation. This finding directly informed the firmware architecture of his open-source 'Kinetic Sync' library.
Why does Sans avoid using the term 'range anxiety' in his public talks?
He argues it misplaces responsibility, framing a systemic infrastructure gap as a psychological flaw in users. In his 2023 TED Talk, he replaced it with 'coordination latency,' emphasizing that drivers aren’t anxious about distance, but about unpredictable mismatches between navigation ETA, charger availability, and thermal battery constraints.
