The sampling rate for test data during testing shall be ≤50 ms. 7.8.4 Requirement The following data shall be reported: energy efficiency at SOC 65 %, 50 % and 35 % for the test temperatures RT, 40 °C and 0 °C. 7.8.5 Calculation example for energy efficiency test Based on a fictive 300 V battery with 6 A⋅h capacity, the results shall correspond (estimated) to the following data: — discharge/charge during 12 s discharge at 20C: 0,4 A⋅h; — electrical power assist (e.g.): 32,40 kW; — regenerative power (e.g.): 39,60 kW; — SOC swing: 6,667 %; — energy output during 12 s discharge at 20C (e.g.):108 W⋅h; — energy input during 16 s charge at 15C (e.g.): 132 W⋅h; — energy efficiency 81,8 %. NOTE These values seem realistic, appearing during typical acceleration or boost phases during driving.
