This system is suitable for comprehensive performance testing of lithium polymer, lithium ion, nickel hydrogen, nickel cadmium, lead acid and other batteries, Battery Materials Research, The formation and capacity separation of small batch battery production, Assembled battery, laptop/tablet battery, smart phone battery, charging treasure, new energy electric vehicle single 18650 lithium battery and other product testing.




  1. The system hardware is stable and reliable, and each channel has independent constant current and hardware constant voltage source.

  2. Each channel can set the work step independently; increase the professional work step setting scheme; in any case, "stop" (including power off) work step "connect" function.

  3. Data acquisition speed is fast, accurate capture of voltage and current changes in detail, with log function. Powerful data and curve processing, report function. Data and curves can be exported to excel and word. Data and curves can be edited.

  4. Various types of fixtures can be used to test different types of electric cores, button batteries and composite batteries.

  5. Can be used offline, measurable temperature and internal resistance, and laptop battery smbus function

  6. It can be connected by serial port, network and USB. Using c/s mode, remote control.
