Product Parameters

Deviation condition

When the absolute value of the ΔV between the main channel and the auxiliary channel exceeds the set value, the voltage callback check deviation will not be judged.
Protect

During the test, if the battery parameters meet the protection conditions of the test process, the battery test will be stopped automatically.
Unit ID

Logical ID of the device.
SIM

The properties test of battery under the simulation of electric vehicles in different states.
Lowest discharge voltage

The lowest allowable lower limit of the test instrument when the battery is discharged.
Voltage accuracy

The relative error between the actual output voltage and the theoretical output voltage.
Constant voltage cut-off current

The current at which the battery terminates the test while the voltage remains constant.
Charging and discharge conversion time

The time required to transition from a charging step to a discharge step.
Galvanostatic charge/discharge

The battery is charged/discharged at a constant current.
Constant-voltage charge/discharge

The battery is charged/discharged at a constant voltage.
Constant current and voltage charge/discharge

Charge/discharge at a constant current to a set voltage, and then charge/discharge at a constant voltage.
Constant-power charge/discharge

The battery is charged/discharged at constant power.
Pulse charge and discharge

The battery is charged and discharged at intermittent current/power.
Constant-resistance charge/discharge

The battery is charged/discharged at a constant resistance.
Minimum Pulse Width

The minimum pulse width of a battery charging or discharging device refers to the shortest time interval between current or voltage changes applied to the battery terminal during the process of battery charging or discharging.
DC internal resistance test

DCIR test is the DC internal resistance test, which refers to the ratio of the battery voltage change to the corresponding discharge current change under working conditions.
Cyclic test

The battery is tested repeatedly under certain conditions.
Software and hardware protection

Charge and discharge equipment in various test conditions to protect the safety of the equipment equipped with various functional modules.
Power-down data protection

When the power supply is abnormal, the system stores data in a timely manner to prevent data loss.
Voltage limit protection

When the voltage exceeds the maximum and minimum values, the device starts the protection state.
Current limit protection

When the current exceeds the maximum and minimum values, the device starts the protected state.
Capacity minimum limit protection

If the current working power is greater than or equal to the set value, the channel is protected.
Galvanostatic charge/discharge

The battery is charged/discharged at a constant current.
