Power Battery Short Circuit Test Machine
Remote control large current short circuit devices are designed according to standard requirements of various kinds ofbattery short circuit test.It applys to many standard specifications,such as GB IEC EN UN38.3 UL QC/T 743-2006 Lithium ion battery for electric vehicle,Lithium ion power battery pack and system for electric vehicle part 3:Safety requirements and test methods,“863 plan”Energy saving and new energy vehicles major projects 2008 EV lithium ion power battery performance test specification etc.According to standard requirements,the short circuit device mustconform to the internal resistance range<5mΩ(or20mΩ),so that maximum short-circuit current,which is required for the test, would be measured.
Equipment design discription:
This devices are designed according to standard requirements of various kinds of battery short circuit test, so thatmaximum short-circuit current,which is required for the test, would be measured.
Besides, short circuiting device must also be able to withstand large current impact.So we choose the industriallevel DC electromagnetic contactor, pure-copper wiring terminal and internal copperplate to deflect, which effectively improve the cooling effect and ensure the security of large current short circuit device , effectively reduce the loss of test equipment, ensure the accuracy of test data.
Adopts PLC man-machine interface control mode.Use the relay contactor as switching element, set up the test conditions on the interface of PLC. Actuation of contactors emits strong short-circuit current ,which reaches the current required by the test.The loop resistance in the process (i.e. contactor resistance + connecting pin wiring + battery clamp) smaller than 5mΩ(or 20mΩ). The maximum short-circuit current that testing circuit can withstand is 5000A. The battery surface temperature,voltage change data and current change data are detected by collecting element and feed back to PLC main control program.
