Cell Resistance / Capacitance Test
Battery cell is the smallest unit of the battery. Selecting a battery cell with a better capacity and internal resistance consistency can ensure stable performance and greater output capacity of the battery module or battery pack after series and parallel connection. Therefore, in the test of cell, resistance and capacitance testing becomes particularly important. ITECH ITS5300 cell test system supports the simultaneous testing of hundreds of channels.

Functions and Advantages
Battery DCIR/ACIR Test
The internal resistance of the battery is related to the discharge capacity of the battery. The larger the internal resistance, the smaller the charge and discharge rate of the battery, which will easily cause the battery to generate heat. ITECH provides battery AC internal resistance and DC internal resistance measurement functions. The AC internal resistance is matched with a special AC internal resistance tester to apply a 1KHz excitation signal to both ends of the battery to measure the internal resistance of the battery under static conditions. However, under the real condition, it also includes the polarization internal resistance, the impedance of the connection point, etc. The DC resistance test can more directly reflect the resistance value of the battery in continuous application.
Battery Capacity Test
Because the battery capacity is affected by the ambient temperature and discharge rate, the capacity test is usually combined with the temperature characteristics and discharge rate. The higher the temperature, the larger the capacity; the larger the discharge rate, the smaller the capacity. ITS5300 system can integrate the control of thermostat, and simulate the environment of normal temperature, high temperature and low temperature. ITS5300 system provides the function of user-defined X-axis and Y-axis parameter categories. You can set the Y-axis as the capacity and the X-axis as the time to obtain the corresponding curve.
Battery Cycle Life Test
The battery cycle life test is one of the necessary test items for the battery. When the capacity declines to 80% of the original, the life can be considered to end, and the battery life is generally obtained by cyclic charging and discharging. Speaking of the factors affecting battery life, in addition to temperature and frequency of use, dynamic operating conditions will also accelerate battery aging. ITS5300 provides pulse charge and discharge mode and edit steps according to rich charge, rich discharge curve marked in the ISO12405-4-2018 standard.
Coulombic Efficiency Test
Coulombic efficiency describes the efficiency with which charge (electrons) is transferred in a system facilitating an electrochemical reaction. The closer the discharge charge is to the charge, the higher the utilization rate of the battery. If the ratio is small, it indicates that the technical or other aspects of the battery need to be improved. For batteries with good characteristics, high-precision test equipment is necessary for telling the difference between the charged and discharged charges. ITS5300 presents ultra-high sampling rate and measurement accuracy.
The HPPC test is a very important test in electric vehicles. It is used to test the performance of hybrid and pure electric vehicles. It is a common test item when evaluating battery systems / modules or single cells. The main test purpose of HPPC is to establish the relationship between discharge depth and power within the battery voltage range. The second is to use the voltage and current curve to establish a function of the discharge depth, conductive resistance and polarization resistance. Then it can evaluate power degradation during life testing by the resistance measurement results. It is a detection method for fully analyzing power batteries. ITS5300 supports users to edit discharge pulse and feedback pulse value according to HPPC curve.
Battery Over-charge / Over-discharge Endurance Test
For a sealed secondary battery, in the case of overcharging and over discharging, gas will quickly accumulate in the sealed container, and the internal pressure will rise rapidly, which will easily cause the battery to explode. So overcharge and over discharge are important test items to test the safety performance of the battery. Under a certain degree of overcharge, the shape of the battery should not change and catch fire. In order to ensure the safety of the battery, it should be specified of the battery's charging limit voltage, charging upper limit voltage, lower discharging limit voltage, maximum charging current and recommended charging current.
Equilibrium Charge and Discharge Test
The differences in the manufacturing and use processes will cause inconsistencies in the cells inside the battery, which are manifested in terms of cell capacity, internal resistance, and charge and discharge efficiency. In order to avoid the life and capacity loss of the overall battery pack caused by degradation of individual performance, BMS generally has a balanced function. At present, the balancing strategy of each BMS is different. The individual cells can be balanced with each other or an energy-consuming method may also be adopted. A resistor is connected to the back end of each cell to consume the power of the cell with a higher power. ITS5300 can accept the balanced start and stop signals of the BMS during the charging and discharging process. Adopting balancing operation of the BMS during the charging and discharging can prevent large differences in battery cells and extend battery life.
Equilibrium Charge and Discharge Test
When the power battery pack is placed in the vehicle for testing, the battery charging and discharging system needs to simulate the DC charging pile to interact with the BMS. It can dynamically adjust the charging parameters according to the request of the BMS or stop charging when receiving wrong messages. The ITS5300 system supports the import of DBC files, and after the operation ends, all CAN messages sent and received during the process are recorded.
Simulate Dynamic Road Condition
ITS5300 provides comprehensive dynamic operating simulation functions for EV battery applications. Users can import 10,000,000 points of current waveform data to simulate the process from battery consumption or reverse charging during starting, braking, acceleration and deceleration of an EV under different road conditions in cities or suburbs. The .csv file import is available. ITS5300 software can also help to calculate vehicle mileage for vehicle manufacturers which reflects the performance of electric vehicles more directly.
Acousto-Optic Emergency Stop
The ITS5300 battery cell / module / battery pack test system provides audio and visual emergency stop protection device. When an abnormal situation occurs, the emergency stop button can be used to quickly cut off the output and ensure that the equipment is powered off reliably. The cabinet is equipped with three-color lights, which indicate different operating states through red / yellow / green lights, which is convenient to identify the status of the system from a long distance and provide audible alarm.
Power-Off Memory Protection
Battery performance verification is often a long-term test process. The power-off memory protection module is designed and developed specifically for long-term testing. It can effectively ensure that the long-term test data is protected from abnormal power failures or computer crashes. After the system resumes normal operation, the program continues to execute the next steps, avoiding repeated testing and improving the safety and reliability of the experiment.
Anto-Reverse / Anti-Spark Protection
Anti-reverse anti-spark module is a functional module specially designed to improve safe wiring and reliable power-on. It prevents from the fire phenomenon caused by the suddenly battery charging to internal capacitor of the device during the wiring. And also prevent the battery from being reversely connected to both ends of the device and result in equipment damage.
User Rights Management
The ITS5300 test system can set different operation permissions for people in charge of quality, R&D, and production through the user permission setting function. So it can prevent system programs from being arbitrarily modified or artificially stopped abnormally and ensure the reliability and security of the system.
Comprehensive Charge and Discharge Protection
In the battery BOL test, to avoid overcharging and over discharging of the battery, it is necessary to monitor the status of the single cell and the entire battery pack in real time, and when the certain conditions are reached, the circuit is cut off in time to protect the battery. The ITS5300 system provides comprehensive protection, including over and under voltage of each channel and cell, pressure difference of cell, over temperature, over power, etc. Users can customize single or multiple protection settings based on battery specifications.
Anti-Islanding Protection (Regenerative System)
For the energy regenerative battery system solution, the instrument has an anti-islanding protection function to prevent itself from keeping feeding back energy to the grid in the event of a mains power outage, causing unnecessary injury. The energy regenerative system provides pure AC power(harmonics<5%). The feedback energy can be used as power supply for other equipment in the plant, good for saving electricity costs, especially for high power applications where a battery pack or a large number of cells are tested simultaneously.
