The working principle of the automatic calibration metering device provided by the invention is as follows:
the control computer is in wireless communication with the calibration tray, the calibration tray switches a calibration or metering channel in a charging/discharging/constant-voltage state, when the control computer sends a charging calibration/metering command through wireless communication, the calibration tray sends a command to the singlechip when the calibration tray calibrates or meters charging current, the CH and COL1 ports of the singlechip are low-level, the DH, HY, ROW ports are high-level, the coils of the relays K1, K2, K3 and K4 are electrified, corresponding contacts are closed, current of a circuit is generated by the charging and discharging device, flows out from the positive electrode probe, finally reaches the negative electrode probe through the K1B, K B, the current divider and the K3B, and returns to the charging and discharging device, so that a charging current calibration or metering loop is formed. Similarly, when the calibration metering device receives the calibration or metering of the discharge current, DH and COL1 ports of the singlechip are low level, CH, HY, ROW ports are high level, and then coils of the relays K1, K2, K3 and K5 are electrified, corresponding contacts are closed, the current flows out from a +5V direct-current voltage source and finally returns to the negative electrode of the switching power supply through the K5B, K B, the positive electrode probe, the charge-discharge device, the negative electrode probe, the K3B and the shunt, so that a circuit for calibrating or metering the discharge current is in a stroke.

When the calibration metering device receives constant voltage calibration or metering, the HY and COL1 ports of the singlechip are low level, the CH, DH, ROW port is high level, the coils of the relays K1, K2, K3 and K6 are electrified, current is generated by the charging and discharging device, flows out of the positive electrode probe, finally reaches the negative electrode probe through the K1B, K6B, R1 and the K6C, K B, and returns to the charging and discharging device, so that a constant voltage calibration or metering loop is formed.
