DiLiCo cell voltage reliably measures the cell voltage of every single cell in the stack. The recorded measurement data are transmitted to your control system via an RS232 or CAN interface. The device has an external power supply (15 - 36 VDC) and a 50-pin D-Sub socket for connecting the cell voltage taps. The measuring system is suitable for all common energy converters and accumulators for cell voltages up to 4.5 V. Use DiLiCo cell voltage to detect faults and unfavorable operating conditions in good time, reducing or avoiding downtime and maintenance costs.
