Additional information





  • Tracing variation of impedance and capacity by dynamic modeling algorithm,so we can know well about the temperature and use record,meanwhile,we need not to standardize it full-cycled and regularly.
  • By making use of the influence of impedance on loads and temperature,we can make accurate modeling.
  • Mastering battery parameters dynamically,so we can guarantee the accuracy of the measurement of power.
  • Maintaining precision measurement of battery capacity by using Impedance Track algorithm.
