Charge faster. Degrade less.
e-TRNL builds thermal intelligence for two-wheeler and EV battery pack engineers. Fingerprint your cells, optimize your charge protocol, and model cycle life before you commit to BMS firmware.
The gap in pack engineering
Conservative protocols waste capacity
Standard CC-CV charge schedules are calibrated for worst-case thermal headroom, not for your specific cell geometry, ambient range, or pack topology. The safety margin you inherit is not yours, and it costs you charge time and cycle depth every cycle.
Aggressive charge shortens pack life
Pushing C-rate without spatial thermal context generates uneven temperature gradients across the pack. Cells that run hot faster degrade faster, creating a capacity mismatch that compounds over hundreds of cycles until the weakest cell limits the whole pack.
Simulation-to-BMS transfer is manual
Bridging electrochemical simulation results to firmware-level charge protocol parameters requires thermal modeling expertise most pack engineering teams build piece by piece. The result is a disconnect between what the model says is safe and what the BMS actually executes.
The e-TRNL platform
Thermal Fingerprinting
Build a spatial thermal model from your cell geometry, impedance spectrum, and temperature readings. The fingerprint maps how heat distributes across your specific pack topology so every downstream decision is grounded in your actual hardware, not a generic cell approximation.
