Processes of battery pack development

  1. STEP 1
    • Determine battery pack specification(output/capacity)
    • Battery Cell basic data measurement
    • Examined the battery management algorithms
    • The SOC judging method examination... etc.
  2. STEP 2
    • Cell monitoring system
    • Voltage monitoring, Current limit, Temperature
    • Monitoring, Balance circuit, SOC operation
    • Battery pack management system
    • Communication with Vehicle ECU
    • Fail safe function
  3. STEP 3
    • Automotive battery Case
    • Safety/ Cooling performance confirmation
    • Installation battery ECU
    • High voltage cable/ Contactor... etc.
  4. STEP 4
    • Simulation under actual condition
    • Performance/ Life evaluation
    • High/ Low temperature test... etc.

Battery Management System[BMS]
by PUES

BMS is the system which can use Lithium-ion
battery pack safely.
It can achieve energy management and fail safe
at the time of trouble occurrence.
