Standards the test plan has to carry
A battery test plan is not one standard. Transport (UN 38.3), safety (IEC 62619), market access (EU 2023/1542) and process (ASPICE) sit in the same spec, often split across cell, module and pack.
Cevelar maps spec clauses onto these mandatory blocks, flags OEM deltas and gaps (samples, acceptance, DUT level) and outputs a plan the lab can book. The battery passport hangs off the regulation: about 90 fields, mandatory from 18 February 2027 for EV, LMT and industrial batteries above 2 kWh.
