Battery Module Maintenance and Certification Test

Application: Any battery or battery pack

Test items:

• DC resistance measurement
  This is the basic action for confirming battery status. The DC resistance (Ohm) affects the battery cell’s capacity and the charge/discharge level of pressure difference. DC Resistance generally tends to be the first hurdle for battery testing or maintenance.

• Capacity test
  This test confirms the capacity of each battery cell. The difference in capacity of each battery cell in the same battery pack should not be very great as a large capacity gap may seriously affect the overall efficiency of battery pack.

• Battery cell balance test
  This adjusts the specific voltage of the battery cells in the battery pack in order to balance the energy levels and overcome the capacity deterioration rate that may cause a mismatched effect within the battery cells. Regular implementation of balancing battery cells helps maximize the battery capacity and life.
  In addition, this function can also be used to create unbalanced voltage conditions for various battery cells in order to perform voltage unbalance related tests (such as UL2271)
