Constant Resistance

Dynamic Waveform Simulation

The feature allows researchers to better understand battery performance in real-world driving condition. In order to achieve the goal, charge/ discharge rapid switch technology is developed, and the less than 5ms switch time makes simulating battery charge/ discharge pattern in real-road conditions become possible. Major international EV testing standards such as Federal Urban Driving Schedule (FUDS) and Dynamic Stress Test (DST) from U.S. Advanced Battery Consortium (USABC) are built-in for drive simulation feature. In addition, users are capable of importing the battery charge/ discharge patterns from a field test, or even defining their own testing patterns.

BMS & Gas Gauge Data Collection

During battery modules/ packs testing, the Gas Gauge/ BMS data is retrieved and recorded.
The data obtained can be used as the condition for program step change or providing protection.
1. Supports communication protocols such as SMBus, I2C, HDQ etc. for IT batteries and Modbus, CANBus etc. for power batteries.
2. Supports CAN .dbc file editing and import.

Chamber Integration

The synchronous control of chambers can be achieved during the testing processes.
Temperature and humidity levels can be adjusted to simulate different environments for measuring the battery’s performance.

Data Analyzer

With Data Analyzer feature, a variety of test data presentations could be adjusted according to the needs of researchers, such as text and graphical reports, self-defined X and Y-axis parameters on graphs and graphs zoom-in / zoom-out. It also helps researchers to easily analyze the data from cycle test. Data from each cycle can be superimposed and drew on a single chart to produce a lifecycle test report. Evaluating test results and finding variation are easy! Moreover, test data can be exported in csv format and manipulated in the third-party software that researchers are familiar with, improving the data usability.

BMS/ Gas Gauge Data Collector

Records the static/ dynamic parameters of the BMS in energy/ power batteries. It supports SMBus, I2C, HDQ, Modbus, CANbus and other communication protocols that are commonly used in energy and power batteries, and it is scalable. With GDA 300, users are allowed to define customized parameters as step cutoff condition while running battery test. Additional parameters can also be defined by researchers to collect and analyze advanced data.

Auto Calibrator ACP2 Series

ACP is especially designed to improve the efficiency and precision of calibration for CTE test equipment. It is applicable for CTE equipment with maximum voltage under 20V and maximum current lower than 100A. Its flexible and scalable design can be expanded to include up to 8 meters, thus ACP is capable of calibrating 8 testing channels simultaneously, which greatly reduces labor cost and time. Also, removable shunts and meters are built-in, making it easy to calibrate and maintain.
