A machine can cover a wide range of application requirements, easy to choose the required models for users. Photovoltaic / solar simulation power supply supports edge time independent set for each mode, has double quadrant current seamless switching function, and supports OVP, OCP, OPP, OTP, Vsense reverse and other protection functions.

 Graphical software interface

ITECH high speed high performance photovoltaic / solar simulation power supply has graphical software interface, users can easily use the software to output, measure, display the maximum power tracking status of photovoltaic inverter in real time and record value. Built-in EN50530 / Sandia and other five kinds of regulatory testing procedures, it is convenient for users to test the static and dynamic MPPT performance of PV inverters and generate reports, so as to compare with competitors’ results. Solar simulation power supply also provides the shadow and table mode, the user can enter the 128 ~ 4096 points array to edit any shielded IV curve to achieve dynamic shadow effect and also can store 100 I-V curves under different irradiation and temperature to test the long-term maximum power tracking performance of photovoltaic inverters under different climatic conditions.

 Simulate the output characteristics of various solar cell (FILL FACTOR)

Since solar cell utilization is not only related to its internal characteristics, but also related to weather, season, temperature, irradiation, cloud cover, rain and snow and other factors, solar cell has different I-V characteristics in different periods. Therefore, PV inverter must have a strategy to adjust real-time working point of the solar cell to make it always work in the vicinity of the maximum power point, this process is called MPPT. ITECH high speed high performance photovoltaic / solar simulation power supply can be used to directly simulate various real-life solar cell arrays in a laboratory test environment to test the static & dynamic MPPT performance of photovoltaic inverters.

 Static & Dynamic MPPT performance test

MPPT tracking performance is a very important specification of PV inverter, PV inverter needs a built-in MPPT mechanism to track real-time maximum output power of solar cell. Therefore, some of the industry’s organizations have defined some “standard” test patterns to match all kinds of inverters, which allows inverter manufacturers to test and improve MPPT performance. Build-in MPPT test program of EN50530、SANDIA、NB/T32004、NB/T32004、CGC/GF004, users can set their own Vmp, Pmp, materials and other parameters, test run time and maximum run power percentage, the I-V curve and the real-time trace process are displayed on the screen to verify MPPT performance of the PV inverter, record the data during the whole test and generate report.

Different from the traditional parallel connection, IT6000B and IT6000C use optical fiber parallel technology. After paralleling, the synchronization and performance of master and slave are almost the same as one single unit. And there is no need to calibrate again, which greatly simplifies the parallel connection.Meanwhile it’s helpful on cost control and high equipment utilization.

 Graphical design interface to simulate fuel cell output polarization curve

The output voltage of a real fuel cell stack is affected by driving conditions. When the working current changes, the output voltage of the FC stack is a three-stage curve due to the internal polarization reaction, including electrochemical polarization zone and ohmic polarization zone and the concentration difference polarization zone.

The FCS3000 software is based on the measured fuel cell polarization curve, and allows users to import the .csv file, download it to the device and realize the fuel cell output polarization characteristic curve simulation. In the experiment, the FCS3000 fuel cell simulation software changes the output voltage of the control system according to the polarization curve, and records the parameters such as voltage, current and power in real time, which helps to study fuel cell propulsion systems to provide important experimental data.

Functions and Advantages

Professional System Software

ITS5300 Test System is equipped with a battery charge/discharge testing software developed on the basis of user specifications. By editing test steps, the user may perform constant current charge, constant pressure charge and constant current/power/resistance discharge tests on multi-channel cells or battery packs. Furthermore, the software will help the user monitor cell voltage, temperature and IR, produce charge/discharge curves and monitor and store relevant data.

 Real-time Charging & Discharging Monitor of Each Channel

A battery pack is typically a set of cells connected in series which exhibit different characteristics during charge and discharge. For this reason, monitoring of cells is of great importance. Apart from key parameters of each channel, ITS5300 test system may install a thermograph and IR tester to realize real-time monitoring of cell voltage, IR and temperature. During the test, user can clearly observe the test information of each channel through the software. The software has intuitive colored block charts to symbolize normality or abnormality of cell characteristics and give early warning where necessary, including channel configuration, cell voltage, current, discharge capacity and other parameters. That is not only easy for observation and record, but also improves the testing
reliability.

 Power-off Memory Protection

ITS5300 Test System is superior over traditional integrated charge & discharge device in that it has a power-off memory feature while the latter has single protection configuration only. Power-off memory feature is the most cutting-edge and perfect protection function developed by ITECH and designed for time-consuming aging tests. With the protection function, previously acquired data can be effectively stored intact in case of unexpected power failure or computer crash during a time-consuming aging test and the user may proceed with the test program from the faulty link after the system is back to normal. In this way, repeated tests are avoided for higher efficiency. Likewise, if the power-off state continues for long, the system will automatically cut off the active charge/discharge circuit so as to prevent overcharge and over-discharge and guarantee the safety and reliability of battery testing.

Modular design

ITS5300 Battery charge-discharge testing system is comprised of power supply, electronic load,internal resistance tester, temperature data acquisition instrument and IT9320 software. It breaks through the traditional testing system limitation,providing professional testing steps toimprove testing efficiency. User can choose the most suitable equipments for their own test requirements to build automotive test platform.
