The applicability of the optimized JEVS test method in the study of the peak power test of lithium ion batteries is analyzed based on the experimental results of different test methods. 2. Test methods for peak power 2.1. HPPC test According to the Freedom CAR Battery Test Manual , 1C charge for 10s, reset 40s, 4C/3 discharge 10s.
If this information to Appendix H. The peak power test is to be performed at 10 intervals, during a single . These discharge DOD values are achieved by from a fully charged state to each % DOD at the the 90% DOD step sequence is performed, the battery of its rated capacity (assuming this can be done performed with no regenerative energy applied to
In this paper, the research object is 2.75Ah lithium ion battery. Peak current can be directly characterized by the peak power, so we use HPPC, optimized JEVS and constant current charge/discharge to test the battery peak current between 5%SOC and 95%SOC at different duration in 10℃, 25℃ and 45℃.
This testing determines battery power capability over the cell’s usable voltage range. It is a test profile that incorporates both discharge and regeneration pulses that take place at various states of charge (SOC), and which can be performed under various temperature stressors and current loads.
The peak power of the battery (SOP) is an important parameter index for electric vehicle to improve the efficiency of battery utilization and ensure the safety of the system in the maximum limit. The estimation and prediction of SOP is based on a large number of test data at different temperature, different SOC and different time scales.
The peak power output test is a great way to test your client’s level of anaerobic performance/anaerobic capacity. The purpose of this test is to measure a person’s maximal anaerobic power. In simple terms, this is the maximum amount of power a person can exert in a given time. This can be a great piece of data to have for a client screening.
