• The TAs collect the voltage, internal resistance, and temperature of each cell.
• The TC collects the ambient temperature and the charge and discharge current of battery
strings.
• All sensors and TCs are connected though a UART bus, back to the BC.
• The BC is connected through Ethernet or a serial port to give you centralized management
and allow you to view the health of battery string.
• TAs monitor cell voltage, Internal resistance and temperature, and uploads data through
the COM port:
• TAs are powered by the monitored battery:
• 1V Ni-Cd, 13mA maximum.
• 6V, less than 7mA.
• 2V current absorption, 7mA maximum (no more than 13mA).
• 12V current absorption, 3mA maximum (no more the 7mA).
• Sensors must be installed on a battery with the appropriate voltage for the sensor or
the unit can be damaged:
• 1V Ni-Cd only.
• 6V battery only.
• 2V battery only.
• 12V battery only.
• TCs monitor charge and discharge current and ambient temperature for one string. The TC
communicates with the BC through the COM1 and COM2 serial ports. Each string must have
separate TCs.
• The current threshold is -3 Amp with a sample rate every 20 seconds.
