1. Purpose of the Test: To test each cell/battery is of the type proved to meet the requirements in United Nations Recommendations on the TRANSPORT OF DANGEROUS GOODS, Manual of Tests and Criteria, Fifth revised edition, Amend.2, Section 38.3. 2. Test Quantity: 2.1 Four batteries, at first cycle, in fully charged states. (For T.1~T.5) 2.2 Four batteries, after 50 cycles ending in fully charged states. (For T.1~T.5) 2.3 Five component cells, at first cycle at 50% of the design rated capacity. (For T.6) 2.4 Four batteries, at first cycle, in fully charged states. (For T.7) 2.5 Four batteries, after 50 cycles ending in fully charged states. (For T.7) 2.6 Ten component cells, at first cycle in fully discharge states. (For T.8) 2.7 Ten component cells, after 50 cycles ending in fully discharged states. (For T.8) 3. Test Procedure: 3.1 All detailed test procedures must be based on United Nations Recommendations on the TRANSPORT OF DANGEROUS GOODS, Manual of Tests and Criteria, Fifth revised edition, Amend.2, Section 38.3. 3.2 Test flow shall be followed as below. Test Start Test 1: Altitude Simulation Test 2: Thermal Test Test 3: Vibration Test 6: Impact / Crush (Component Cell) Test 7: Overcharge Test 4: Shock Test 8: Forced Discharge (Component Cell) Test 5: External Short Circuit Test End Page 2 of 8
4. Test Result: 4.1 T.1 ~T.4 Test result: Passed 4.1.1 All batteries could meet the requirement of Table 38.3.1 Mass loss limit (M<1g: 0.5% ; 1g M 75g: 0.2% ; M>75g: 0.1%) and residual OCV not less than 90% after the test. 4.1.2 No leakage, no venting, no disassembly, no rupture and no fire. 4.2 T.5 Test result: Passed 4.2.1 All batteries could meet the requirement, external temperature did not exceed 170. 4.2.2 All batteries were no disassembly, no rupture and no fire during the test and within six hours after the test. 4.3 T.6 Test result: Passed 4.3.1 All component cells could meet the requirement, external temperature did not exceed 170. 4.3.2 All component cells were no disassembly and no fire during the test and within six hours after the test. 4.4 T.7 Test result: Passed 4.4.1 All batteries could meet no disassembly and no fire during the test and within seven days after the test. 4.5 T.8 Test result: Passed 4.5.1 All component cells could meet the requirement, no disassembly and no fire during the test and within seven days after the test. Conclusion: The samples had passed the test items of UN38.3. Page 3 of 8
