| 摘 要： | The test process of electric vehicles (EVs) traction battery peak power is analyzed in detail. Aimed at a special ““traction““ design of versatile battery-HORIZON C^2M Battery, the features are introduced. According to the peak power test schedule, the test parameters of HORIZON C^2M Battery are calculated and the charging and discharging experiments are carried out. The sustained (30 s) discharge power capability of battery at 2/3 of its open circuit voltage at each of various depths of discharge is determined. The dynamic internal resistance under peak power test is established. Considering the temperature impact during discharging, the peak power capability at each of various depths of discharge is corrected. The correctness of peak power test is validated by combining theory analysis with test results.

| Abstract: | The test process of electric vehicles (Evs) traction battery peak power is analyzed in detail. Aimed at a special "traction" design of versatile battery-HORIZON(R) C2M Battery, the features are introduced. According to the peak power test schedule, the test parameters of HORIZON(R) C2M Battery are calculated and the charging and discharging experiments are carried out. The sustained (30 s) discharge power capability of battery at 2/3 of its open circuit voltage at each of various depths of discharge is determined. The dynamic internal resistance under peak power test is established. Considering the temperature impact during discharging, the peak power capability at each of various depths of discharge is corrected. The correctness of peak power test is validated by combining theory analysis with test results. |
