​​BATTERY RESISTANCE TESTER


The battery resistance tester was requested by a California-based manufacturer of electric vehicle lithium-ion batteries. The tester applies a brief, high-current load to a battery to precisely measure its' internal resistance. The fixture includes an interface to the manufacturer's Battery Management System (BMS). The software records the measured battery parameters, and the data provided by the BMS, in a production log file. 


Specifications:

  • ​For use with lithium-ion traction batteries up to 12V, 1000Ah
