N8130 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
N8130 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.
QC/T 741 DCIR calculation:
N8130 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, processes, storage and many other links.
During the supercapacitor test, a large current will be outputted, which will cause a voltage drop in the leads and affect the measurement accuracy. N8130 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.
Considering the test application scenarios of different scales, NGI provides two types of test fixture: Kelvin clamp and 12-channel special fixture. Both test fixtures support four-wire connection.
1) N8130 software adopts a platform design, which allows the users to customize the test process according to their requirements.
2) 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.
3) N8130 is designed with power limit circuit and has fast response, which can prevent N8130 from being damaged due to over power.
4) N8130 adopts shielding technology, which has wide adaptability to harsh test environment, and improves the anti-interference ability.
