In this section:

  • Battery cover – a signal from the battery cover;
  • Charger connected – a signal indicating that charger is connected;
  • Power up/down request – a request to power down the device;
  • Inhibit charging – a command to open the charging contactor;
  • Inhibit discharging – a command to open the discharging contactor;
  • CH contactor feedback – a signal from charging contactor feedback loop;
  • DCH contactor feedback – a signal from discharging contactor feedback loop;
  • Insulation status – a signal from an insulation monitoring device;
  • Charge request – a request to close the charging contactor;
  • Precharge request – a request to close the precharging contactor;
  • Discharge request – a request to close the discharging contactor;
  • PCH contactor feedback – a signal from precharging contactor feedback loop;
  • CH/DCH contactor feedback – a signal from charging/discharging contactor feedback loop;
  • Main contactor feedback – a signal from main contactor feedback loop;
  • Interlock – a signal from interlock loop;
  • Fuse 1, Fuse 2, Fuse 3 – signals from fuses;
  • Circuit breaker status – status of protection disconnector;

In this section:

  • Online – a flag showing that the communication with the BMS Current Sensor is established;
  • Errors – a list of internal errors of the shunt sensor;
  • Current – an instantaneous value of current measured by the BMS Current Sensor, A (measuring frequency is 50 Hz);
  • Current (mean) – a mean value of current measured by the BMS Current Sensor, A (the value is calculated as an average of 100 consistent measurements);
  • Temperature – a temperature of the shunt sensor, °C.
