Open engineering · evidence first

Inspect the model, the result, and the boundary before trusting the claim.

This collection connects battery physics, estimation, power conversion, grid operation, and project acceptance through executable models, research benchmarks, playbooks, notes, and evidence controls.

Collection map

From cell behavior to accepted project evidence.

  1. 01Battery physicsElectrical states, heat generation, cooling, degradation
  2. 02EstimationSOC correction, fitted degradation, bounded EOL/RUL
  3. 03Power conversionDC link, converter dynamics, active and reactive limits
  4. 04Grid operationFollowing, forming, voltage, frequency, reserve, energy
  5. 05Project acceptanceRequirements, tests, evidence IDs, revisions, handover

Evidence legend

Validated does not mean universally qualified.

Validated reference
Automated checks passed for stated equations, invariants, or scenarios at a pinned source.
Research benchmark
Experimental protocol and result bundle are inspectable; deployment claims remain out of scope.
Illustrative / synthetic
Useful for demonstrating a method, never presented as measured plant or cell performance.
