Battery short-circuit tester
The device is designed based on a variety of battery short-circuit test standards.
According to the standard requirements, the short-circuit device must meet the
internal resistance range of 80 soil 20m, so as to obtain the maximum short-circuit
current required by the test. In addition, the circuit design of the short-circuit device
must also be able to withstand the impact of large current, so we choose industrial
grade DC electromagnetic contactors and all copper terminals and internal copper
plates to guide the flow, wide and thick copper plates effectively improve the heat
dissipation effect, make the high-current short-circuit device safer, effectively reduce
the loss of test equipment, and ensure the accuracy of the test data.
Meet the standard
GB/T31485-2015 "Safety requirements and test methods for power batteries for
electric vehicles"
GB/T31241-2022 "Safety requirements for Lithium-ion batteries and battery packs
for portable electronic products"
UN38.3 United Nations Manual of Tests and Standards for the Transport of
Dangerous Goods
IEC62133 "Safety requirements for batteries （groups） composed of cells and for
use in portable equipment"
UL1642:2012 "Lithium Battery Standard"
