 Linear Circuit Series Features

Stable & Low Noise Output

Chroma 17010 is equipped with low output noise and high measurement accuracy. The test current and voltage data can be converted into highly accurate and clear characteristic peaks to efficiently research the aging mechanism of Li-ion batteries.

High-precision & Multiple Current Range Design

Quick switching of current ranges: Chroma 17010 series provide multiple current outputs and measurement range switching, fitting test plans with both large and small currents. At the start of a test step, the system will detect the output current and then automatically and quickly switch to the appropriate current range. This improves the test accuracy and resolution for highly accurate test data.
Automatic range switching under constant voltage mode: Chroma 17010 linear circuit models support automatic switching of the current range in the constant voltage test mode, without any output interruption. This is perfect for applications such as float charging or potential regulation, which require long-term and highly stable testing of extremely small current output.

Three Voltage Ranges

Chroma 17216M-10-6 model built in three voltage ranges, for more profuse product development applications.

• 0V – +5V: Half-cell, full-cell, EDLC testing

• -5V – +5V: Symmetric battery testing

High-speed Sampling Technology

Chroma 17010 uses high-speed voltage and current sampling with double integration of computing to capture transient changes in the test without distortion. The advanced test system provides more accurate capacity calculations to solve the issue that general battery test equipment only use the report sampling speed to record key data, causing large cumulative errors.

• Hardware internal voltage/current sampling rate: 1mS
• Report single point transient sampling rate: 1mS
• Report sampling rate: 10mS

• Real-time abnormality detection in each tester automatically detects deviations based on independent logic. When the system is interrupted, the test can be continued after the exception is eliminated without missing any data.

③ Integrable chamber and peripheral safety device

• The Battery LEx software provides built-in chamber setting controller and chamber control steps, which can control temperature and humidity, indicate the temperature control time, delay time, and standby temperature, as well as control timeout and over-temperature protections.
• To ensure consistency of the test state, the grouping management structure allows all testing channels in the same chamber to enter the temperature control phase at the same time.
• The built-in DI/DO function can be connected with smoke/gas detection, fire extinguisher, and alarms for over-temperature, over-voltage, and open door. The system performs different levels of handling according to the degree of damage, including stopping the test or powering off. Alarm data can be sent remotely via e-mail.

 Test Applications

Direct Current Internal Resistance (DCIR)

The battery’s internal resistance value is related to its charge/discharge ratio. The larger the internal resistance value, the lower the efficiency when temperature rises. ACIR measurement of traditional 1KHz LCR meters can only evaluate the ohmic resistance (Ro) of the battery that affects the instantaneous power output, but is unable to evaluate the polarization resistance (Rp) produced during electrochemical reaction. DCIR assessment includes ACIR and comes closer to the actual polarization effect of the battery under continuous power application. Chroma 17010 has two programmable DCIR test modes, and – with the variable calculation function – can automatically obtain test results that meet the IEC 61960 standard.

• DCIR (1) is based on the voltage difference caused by one current change.
• DCIR (2) is based on the voltage difference caused by the change between two currents.

Differential Voltage (dV/dQ)

The key to plotting the dV/dQ curve is to charge and discharge the battery with a small current ( < C/20) in order to eliminate polarization effects on the test results. Chroma 17010 has low noise to draw high-definition dV/dQ vs. Q curves, users can view and mark each characteristic peak in detail. The ageing test allows users to analyze the battery’s aging system based on the deviation and height of each characteristic peak.

Hybrid Pulse Power Characteristic (HPPC)

Chroma 17010 has a flexible editing program that can compile HPPC test steps, as used by the U.S. Council for Automotive Research (USCAR) to evaluate the battery performance of new energy vehicles. The purpose is to obtain the open circuit voltage, ohmic resistance (Ro), and polarization resistance (Rp) data of a specific depth of discharge within the operating voltage range, following standard test methods. It establishes a functional relationship between the depth of discharge and the charge/discharge peak power, as an index to evaluate the battery cell’s aging and output power capacity.

Battery Capacity

The capacity can be obtained by integrating current over time, from the start of charging/discharging until the cut-off condition is reached. Common test items include current ratio and temperature characteristics. Comparing the results lets users analyze performance differences between products. Higher accuracy of current/voltage measurement and faster sampling enable to distinguish more accurately the differences in battery cell capacity.

Battery Cycle Life

Cycle life is one of the most important test items for batteries. In accordance with the experimental purpose, it tests the same battery through repeated charge and discharge conditions until the capacity falls to 80%, and then calculates the number of cycles. The cycle life test can be used to evaluate battery performance or define proper conditions of use.

Coulombic Efficiency (CE)

CE is calculated by the charge/discharge capacity ratio when the battery is fully charged and then fully discharged. Good batteries have higher CE, and need high precision and stable equipment to distinguish differences. Chroma 17010 offers accurate CE testing that can estimate the battery lifespan with only a few cycles.

Charge & Discharge Rate

The battery is charged and discharged at different currents to evaluate how its voltage platform and capacitance maintain. Such test results are often used for adjusting the proportion of active materials during product development as well as for verifying performance of power batteries for rapid charging and discharging.

 Optional Calibration System and System Accessories
