Compared to traditional battery cycling that may use exclusively constant current and constant voltage (CC-CV) charge\/discharge profiles, EV testing applications require both cells and battery packs to be charged\/discharged based on various real-world applications. These charge\/ discharge profiles are highly dynamic and require much greater current demands relative to \u201ctraditional\u201d testing.<\/p>\r\n\r\n\r\n\r\n

The Hybrid Pulse Power Characterization (HPPC) Test is intended to determine dynamic power capability over the device\u2019s useable voltage range using a test profile that incorporates both discharge and regen pulses.<\/p>\r\n\r\n\r\n\r\n

The objective of this profile is to demonstrate the discharge pulse and regen pulse power capabilities at various depth of discharge (DOD) values for both the Minimum and Maximum PowerAssist goals (10-s discharge, 10-s regen). The normal test protocol uses constant current (not constant power) at levels derived from the manufacturer\u2019s maximum rated discharge current.<\/p>\r\n\r\n\r\n\r\n

                  The Cold Cranking Test is intended to measure 2-s power capability at low temperature (normally -30\u00baC) for comparison with the Cold Cranking Power target(s). The test is conducted at the maximum DOD (minimum state-of-charge) where CS and CD Available Energy targets are just met, i.e., after removal of the energy required by both targets, based on the most recent L-HPPC data.<\/p>\r\n\r\n\r\n\r\n

                  The Cold Cranking Test Profile is a literal implementation of the Cold Cranking Power targets, which require the ability to provide 7 kW of discharge power for three 2-s pulses at 12-s intervals (i.e., 10 seconds between pulses). The profile is defined in Table and illustrated in Figure below for the Plug-In Hybrid Battery targets.<\/p>\r\n\r\n\r\n\r\n
