5 Frequently Asked Questions about “New Energy Battery Cabinet Polarity Test”
What is a battery test system?
It addresses the evolving battery test requirements for electric vehicles, renewable energy storage and critical power applications. NHR's battery test systems are used as battery cyclers, regenerative, bi-directional DC sources, regenerative DC loads, high power DC sources, or Battery/DC emulators.
How to calibrate discharge current if power supply is not installed?
By below connection, there will be another value indicated by standard meter. If there is no negative power supply installed, the equipment cannot discharge except you connect a battery to function as a power supply. You can calibrate discharge current at this situation just string a battery in the circuit as above diagram.
How to calibrate a negative power supply with constant voltage discharge?
For the equipment with negative power supply and empowered with Constant Voltage Discharge, you can use the same logical as above calibration for charge voltage. If no such conditions, a digital voltage signal source will be introduced for the calibration. Linearity is an important item of MSA (Measurement System Analysis).
How to copy Kb value after CC (charge current) calibration?
If you do not have equipment powered with negative power supply and no available battery function as an external power source, you may choose Copy KB Value on the right click menu after you have finished CC (Charge Current) calibration.
What is a channel in a battery test?
Each location on the tester that tests a single device is called a channel. The number of the channel. Generally it ranges from 1 to 8 in real, and from 1 to 32 in virtual. Also called faradic efficiency, faradic yield, coulombic efficiency or current efficiency. A ratio between output (discharging) and input (charging) capacity of the battery.
