cassie@lionbatterymachine.com1. Relevant standard test requirements
1.1 The test object is a complete vehicle or a complete vehicle-mounted lithium-ion battery system or a vehicle-mounted lithium-ion battery system subsystem including lithium-ion batteries and electrical connections
1.2 Test conditions
The test should be carried out under the following conditions:
A) This test should be carried out in an environment where the temperature is above 0°C, the relative humidity is 15% to 90%, and the atmospheric pressure is 86 to 106 kPa.
B) Before the start of the test, the SOC of the test object should be adjusted to be greater than [90% or 95%] of the normal SOC working range specified by the manufacturer.
C) Before the start of the test, all test devices must be in normal operation.
D) The test should make as few changes to the test sample as possible, and the manufacturer shall submit a list of the changes made.
E) The test should be carried out in an indoor environment or an environment where the wind speed is not greater than 2.5km/h
1.3 Thermal runaway trigger object
Two methods, heating and acupuncture, are recommended as candidate methods for thermal diffusion test of lithium-ion battery system. Manufacturers can choose one of them.
1.4 Heating trigger thermal runaway:
Use flat or rod-shaped heating device, and its surface should be covered with ceramic, metal or insulating layer. For the block heating device with the same size as the lithium ion battery, the heating device can be used to replace one of the lithium ion batteries and directly contact the surface of the trigger object; for the thin film heating device, it should always be attached to the surface of the trigger object; Whenever possible, the heating area of the heating device should not be larger than the surface area of the lithium-ion battery; if the heating surface of the heating device is in direct contact with the battery surface, the location of the heating device should correspond to the location of the temperature sensor specified in 1.6; After the installation is complete, immediately start the heating device to heat the trigger object with the maximum power of the heating device; the power requirements of the heating device are shown in Table A.1, but it is not mandatory; when thermal runaway occurs or the temperature at the monitoring point defined in 1.6 When it reaches 300℃, stop triggering.
Table A.1: Power selection of heating device
Test object energy E (Wh) | Maximum power of heating device (W) |
E<100 | 30-300 |
100≤E<400 | 300-1000 |
400≤E<800 | 300-2000 |
E≥800 | >600 |
1.5 The manufacturer judges whether thermal runaway occurs based on one or more of the following conditions, and at the same time, it is necessary to indicate the conditions for judging thermal runaway in the technical document.
a) The test object has a voltage drop;
b) The temperature of the monitoring point reaches the maximum operating temperature specified by the manufacturer;
c) The temperature rise rate of the monitoring point;
d) Other status parameters defined by the manufacturer.
1.6 Monitoring of voltage and temperature
Figure A.1 Schematic diagram of the layout position of the temperature sensor when acupuncture is triggered
Monitor the voltage and temperature of the trigger object to determine whether thermal runaway occurs. When monitoring the voltage, the original circuit should not be changed. The monitoring temperature is defined as temperature A (the highest surface temperature of the trigger object during the test). The sampling interval of temperature data should be less than 1s, the accuracy requirement should be ±2℃, and the diameter of the temperature sensor tip should be less than 1mm.
When acupuncture is triggered, the position of the temperature sensor should be as close as possible to the short-circuit point.
When the heating is triggered, the temperature sensor is arranged on the side away from the heat conduction, that is, installed on the opposite side of the heating device (see Figure A.2). If it is difficult to install the temperature sensor directly, place it in a position where it can detect the continuous temperature rise of the trigger object.
