Battery Monitoring

Sentinel

S-Box

Technical data:

• One Sentinel per monobloc/cell
• Measures the voltage, temperature, and impedance of the bloc
• Sentinel voltage range from 0.9 to 16V
• Daisy chain communication to the S-BOX for up to 254 Sentinel
• Din rail mounting

Technical data:

• Communicates with 254 Sentinels
• 6 strings/current transducers + ambient temperature probe
• LAN and internet connection
• Different ‘modes’ of operation, reflecting different battery status:
  Normal / Discharge / Recharge
• Minimum of 11 hours of data storage (without discharge)
• Easy commissioning software “Wizard like” (SIMS)
• Graphical viewer software (Cellview net)
• Daily logs (configurable)
• Alarms & Weekly reporting

A software battery management tool that provides information on each of the cell for the user to manage the performance of the battery and scheduling the maintenance programs.

The Benefits:

• Greatly reduces the time required to review battery data
• Allows for easy graphical analysis and data interpretation
• A planning tool for scheduling maintenance work
• Saves money in reduced staffing required to gather the system data

Each Sentinel needs two Washers, one Power Cable (incl. temperature probe) and one Communication Cable.

Each S-BOX needs one S-BUS Converter to interface with the serial input.

One current transducer is needed for each string. LEM can offer differents series for it: DH Series and DK Series.
