Glossary	You hit a term you don't recognise (battery subsystem, thermal event, housing crack, etc.). One page per defined term.
Symbols and abbreviations	You need to remember what I₁, I₃, BCU, RMS, PSD, FS mean.
Vehicle category cheat sheet	A test parameter depends on M1/N1 vs other, or on curb weight tier (≤3.5 t / >3.5–<7.5 t / ≥7.5 t).
Referenced standards	A test method points at GB/T 2423.x or similar and you want to know what those standards specify.
Typical pack and system structures	You need a primer on how packs/systems are typically architected (Appendix A reference).
Index by clause number	You have a clause citation (e.g., "8.2.16") and need to find the wiki page. The clause-sorted alternative to the cheatsheet.
