Share:

Relevant standards requirement

Temperature shock

  1. Test Object: Battery storage pack or system.
  2. Li-ion battery pack or system placed in (-40±2) ℃~ (85±2) ℃ alternation temperature, the conversion time of two extreme temperatures is less than 30 minutes. Place the test objects into each extreme temperature keeps 8h, test 5 cycles.
  3. Observe for 2 hours under the room temperature after testing,

 

Humidity & Temperature Cycling

  1. Test Object: Battery storage pack or system.
  2. Refer to the GB/T2423.4 Test Db, variable refer the Graph 4, the highest temperature is +80℃, 5 cycles. Observe for 2h under room temperature.

 

Y1: Relative humidity %RH;    Y2: Temperature, ℃;       X: Time, h;

a: end of the heating;      b: cooling start;

c: recommended temperature and humidity values;

d: condensation;         e: desiccation;        f: 1 cycle.
