    Setting the Frame Address A unique address must be assigned to all devices on the TP-BUS for the control unit to identify the unit frames connected to the TP-BUS. This address is called frame address. CAUTION • The frame address of the unit frame is set to 1 when it is shipped from the factory.
  • Page 33 Node number Unique numbers are assigned to the charge/discharge power supply units that are installed in the unit frame. This number is called node number. Node numbers are assigned according to the frame address and physical address as shown in Fig. 1-8. Physical address refers to the address that is determined by the slot position of the unit frame.
  • Page 34 Fig. 1-9 shows an example in which the maximum number of PFX2021 Charge/ Discharge Power Supply Units is connected to a single control unit. The maximum number of unit frames that can be connected to a single control unit is 12. The PFX2021 has one channel per unit. Therefore, the maximum number of channels that can be connected to a single control unit is 60.

  • Page 35: Connecting The Tp-Bus

    You can connect 12 unit frames and one impedance measurement unit to the control unit. NOTE • The control unit is a dedicated controller for the PFX2000 Series. You cannot con- nect Kikusui power supplies (such as the PMR Series) with the TP-BUS interface and control them.

  • Page 90 ■ Measurements during pulse charge/discharge operation The measurement method during pulse charge/discharge operation differs between the PFX2011 and the PFX2021. PFX2011 During pulse charge/discharge operation, the unit makes measurements at the fol- lowing times. If the specified pulse time is greater than or equal to 1.5 ms, the current and then the voltage are measured immediately before the next current value is set as shown in Fig.
  • Page 91 PFX2021 As shown in Fig. A-7, voltage measurement and current measurement are per- formed independently at the same time regardless of the specified pulse time width.

  • Page 92 ■ Pulse current measurement PFX2011 In pulse current measurement, each pulse current is measured and the average cur- rent is calculated over a unit time. IM1 • T1 + IM2 • T2 + IM3 • T3 + IM4 • T4 Average current = (Equation 1) Tave...
  • Page 93 NOTE • Points to note concerning the PFX2011 pulse current measurement • The calculation result of the average current is output after the relevant unit time for averaging has elapsed (this is also the same as the case shown in Fig. A-9). The average current calculation function of the unit is operating asynchronously with the period of the specified pulse waveform.

  • Page 95 ■ Moving average process You can decrease the fluctuation of the measured value even further by performing moving average. The unit allows you to select the average count from n = 0 (OFF), 2, 4, and 8. Fig. A-13 shows an example of the moving average process when n is set to 4.

  • Page 96: Power Regeneration Function

    Power Regeneration Function The power consumption can be reduced on the PFX2021 system (combination of the PFX2021 and PFX2332) using the regeneration function. This function extracts a portion of the battery discharge power from a discharging charge/discharge power supply unit and uses the power to run the fan or to charge other batteries of other units in the same frame.
