Compare with SSR (Solid State Relay), the Chargery DCC is bi-directional and can handle up to 600A current at 100V DC. ONE Chargery bi-directional DCC can be used in common port, and receive both HV and LV cut off signal. If not using the Chargery DCC, you would require two SSR's or two relays, which would increase power consumption and have a higher cost. -
Page 36: Current Calibration (Shunt)
BMS16T V4.1 Current Calibration (Shunt) Current calibration is only required if you change the Shunt from the one supplied by Chargery which are calibrated at the factory. Use shunts which are 75mv or lower only. Press SET/START for 3 seconds to enter into Program Setup and find the Current Calibration, you can calibrate the current to improve the measurement accuracy. - Page 37 Current calibration is not suggested. We calibrate shunt and current before delivery. You only need to re- calibrate if you change shunts from the ones supplied by Chargery. If the current is not accurate, the WH and AH will not be accurate. SOC reading will also be wrong.
