This document describes the performance and durability test procedures and calculation methods for alkali-ion (for example Li-ion, Na-ion), Pb, NiMH and combined chemistries EV battery systems, battery packs, battery modules and battery cells. This document considers the most appropriate metric based on application for electrical performance between different models/products on the market. It specifies performance test procedures and calculation methods to obtain performance and durability values for:
-
rated capacity (in Ah) and capacity fade (in %);
-
power (in W) and power fade (in %);
-
internal resistance (in ê¥) and internal resistance increase (in %);
-
energy round trip efficiency and its fade (in %);
-
expected lifetime (number of reference cycles).
