Test objects: The test object is the whole vehicle or the complete vehicle-borne ion battery system or the subsystem of vehicle-borne lithium-ion battery system, including a lithium ion battery and an electrically connected lithium ion battery.
Test conditionsThe test shall be started under the following conditions.
Testing should be started at temperature higher than 0 ℃, relative humidity 15%~90%, and the atmospheric pressure 86~106 kpa.
.Before testing, The SOC of the test object should be adjusted to 90% or 95% of the normal SOC working range specified by the manufacturer.
Before testing, all the test device must be running normally.
The test objects should be modified as little as possible when testing, and the manufacturer should submit a list for all changes.
Testing should be at the room temperature or wind speed is not more than 2.5 km/h.
3. Thermal runaway trigger object Heating and needling are recommended as candidates for thermal runaway test of lithium ion battery systems. Manufacturers can choose one of them.
