Power Short Circuit Battery Testing Equipment 304 Stainless Steel Plate
Remote control large current short circuit devices are designed according to standard requirements of various kinds of battery short circuit tests. This equipment applies to multiple standard specifications including GB, IEC, EN, UN38.3, UL, and QC/T standards for lithium-ion batteries used in electric vehicles and other applications.
According to standard requirements, the short circuit device must conform to internal resistance range <5mΩ (or 20mΩ) to measure the maximum short-circuit current required for testing.
This device is engineered to withstand large current impacts while measuring maximum short-circuit current. We utilize industrial-level DC electromagnetic contactors, pure-copper wiring terminals, and internal copper plates to effectively improve cooling performance and ensure security during large current short circuit operations.
The design effectively reduces test equipment loss and ensures the accuracy of test data through robust construction and optimized thermal management.
Utilizes PLC human-machine interface control mode with relay contactors as switching elements. Test conditions are set on the PLC interface, and contactor actuation generates strong short-circuit current meeting test requirements.
The loop resistance (contactor resistance + connecting pin wiring + battery clamp) is maintained below 5mΩ (or 20mΩ), with maximum short-circuit current capacity of 5000A. Battery surface temperature, voltage, and current data are detected by collection elements and fed back to the PLC main control program.
