Intelligent CHARGING

  • Can we determine the remaining service life of the battery?
  • Actual capacity is an indicator of battery health.
  • Calculating the actual capacity by state of charge and charged energy.
  • Continuous capacity test.
  • Gives a good indication of the remaining lifetime
  • Can be compared to actual usage (low electrolyte level, temperatures, deep discharges) to determine the service life affect of different usage
  • SOC algorithm with SOH determination in BMU (gen II)
