Mau electronics in order to strengthen the power to test cover rate and efficiency Of energy storage battery industry, has developed a lithium battery module automatic test system solutions, can be applied to the battery pack in Line terminal (End Of the Line, EOL) test before delivery, including assembly, battery management system (BMS) communication, the internal switch parts, battery balance consistency, temperature distribution, etc., belongs to the comprehensive PASS/reject (PASS/FAIL) test.

This PASS/reject (PASS/FAIL) test not only can be used in the production line, nearing completion in development stage or electric/energy storage battery pack into the material inspection, integrity can be used to do a comprehensive judgment.Test automation can avoid error and ensure personnel safety, application areas include electric vehicles, electric locomotive and energy storage battery module of the system.

Test system was in line to the end of the test of the battery pack before shipment, including assembly, battery management system (BMS) communication, the internal switch parts, battery balance, temperature distribution, etc., is a comprehensive PASS/reject (PASS/FAIL) test.

This test is not only in the production line, nearing completion in development stage, or the battery pack into the material inspection, all the integrity of the comprehensive judgment can be used to do a short time.

(1) insulation test: High end/casing pressure & insulation test High voltage terminal EMC screening test Grounding short circuit/bonding test	(2) the electrical testing: High/low pressure relay switch function test High pressure Interlock (Interlock) line detection The temperature sensors read value/temperature range detection Single cell voltage value/static voltage difference detection
(3) the software/communications test: BMS burning software version confirmation/procedures/read/write the serial number/transportation test/water cooling mechanism, the... CAN error code diagnosis/BMS monitoring function	(4) battery pack performance test: The standard charge and discharge capacitance/condition simulation test Dynamic resistance measurement (DCIR Test) Open circuit voltage measurement

Connect with customized battery module fixture and automatic switch control ability

(A) the battery module and connecting fixture box example of automatic test system

(B) + drive signal control Digital I/O card, fixture On/Off automatic hydraulic/pneumatic switch, or the warning bell ring
