Functions & Advantages

Capacitance test 

N5800 can measure the charging capacitance and discharging capacitance of supercapacitor. The test method is as follows: charge or discharge the measured supercapacitor under CC mode, record the time and voltage during the charging or discharging process, and calculate the capacitance by calculating the slew rate of the voltage and time during the process.

Users can choose voltage and time for calculation according to various measurement standards, such as IEC.

Charging capacitance calculation: 

Discharging capacitance calculation: 

Ur: Rated voltage

U1: Start voltage for charging capacitance

U2: End voltage for charging capacitance

U3: Start voltage for discharging capacitance

U4: End voltage for discharging capacitance

I1: Charging current

I2: Discharging current 


DCIR test

N5800 supports a variety of DCIR test methods: multi-pulse, single-pulse, charge-to-discharge, six-step test and IEC test, which can meet the test needs of most users. NGI core technology ensures that highly accurate results are obtained in various test methods.

Life test

N5800 can measure the physical parameters of the supercapacitor during the repeated charging and discharging process and extract its attenuation curves. By analyzing the parameters and curves, users can obtain the expected life of supercapacitor in different application environments, charging and discharging cycles, and performance index at different stages. Life test results can be used to improve the materials, craft, storage and many other links.


Four-wire sense

During the supercapacitor test, a large current will be outputted, which will cause a voltage drop in the leads and affect the measurement accuracy. N5800 series adopts the four-wire sense system and directly acquires the voltage at DUT output terminals to avoid voltage loss and ensure the measurement accuracy.


No overcharge during charge-to-discharge

N5800 is designed with precision circuit to ensure fast and accurate charging and discharging transition. During the charging process, there is no overcharge during  CC charging converting to CV charging, which can protect the DUT from being damaged.

N5800 has the features of seamless transition from CV charging to CC charging and up to 1ms sampling rate, which can meet the test requirements of QC/T 741, six-step method, and charge-to-discharge method for DCIR.


Application software

1) N5800 software adopts a platform design, which allows the users to customize the test process according to their requirements.

2) N5800 is designed with power limit circuit and has fast response, which can prevent N5800 from being damaged due to over power.

3) N5800 adopts shielding technology, which has wide adaptability to harsh test environment, and improves the anti-interference ability.

4) Office-like interface, independent display of each channel, supporting voltage and current waveform generation, and result display in tabular form make this professional software multifunctional and easy-to-use.
