The standard charge (SCH) procedure at the different temperatures shall follow 6.2.2.3. The standard cycle (SC) procedure shall follow 6.2.All discharge tests shall be terminated at the supplier's discharge voltage limits. All fast charge tests shall follow or shall be terminated at the supplier's requested limits. The sampling rate for test data during testing shall be ≤50 ms. Calculate energy efficiency for the following SOCs: — from SOC at discharge test termination to the next rounded SOC decade and each following 10 % SOC increment up to the SOC level at fast charge termination,— from each rounded SOC decade following the discharge test termination to each following 10 % SOC increment up to the SOC level at fast charge termination, based on measured voltage and current data for each standard discharge and the following fast charge test. Use the following formula for calculation of the requested energy efficiency values:
