This test is performed to characterize thermal durability of a cell by exposing at a low and high temperature environment alternately to cause expansion and contraction of cell components.
Technical Parameters
IEC 62660-2 Test Standard Temperature Test Chamber
Thermal Test
a) Adjust the SOC of the cell to 100% for BEV application, and to 80% for HEV application.
b) The cell, stabilized at room temperature, shall be placed in a gravity or circulating air-convection oven. The oven temperature shall be raised at a rate of 5K/min to a temperature of 130℃±2K. The cell shall remain at this temperature for 30 min before the test is discontinued.
Temperature Cycling
a) Adjust the SOC of the cell to 100% for BEV application, and to 80% for HEV application.
b) Perform the temperature cycling in accordance with ISO 16750-4 as shown in Table 4 the minimum operating temperature shall be -40℃ or Tmin specified by the cell manufacturer and the maximum operating temperature shall be 85℃ or Tmax specified by the cell manufacturer. Perform 30 test cycles as specified.
