Scienlab Battery Test System – Cell Level

Test up to 64 cells, 6 V, ±25 to ±1600 A

Accelerate lab throughput with fast, accurate testing of up to 64 cells using the SL1007A battery cell test system (25 to 1600 A). Our purpose-built Energy Storage Discover software helps you automate common compliance, load, and endurance tests. The system hardware provides excellent accuracy, ensuring precise capacity, efficiency, internal resistance, and cell lifespan measurements. The high-resolution dynamic output produces a realistic power profile, for example, emulating EV driving to characterize cell behavior and performance. In addition, calibrated electrochemical impedance spectroscopy (EIS) measurements and reference-electrode connections enable you to gain deeper insights into the potential benefits of your latest cell chemistry and design innovations. Of further benefit to your lab, this solution keeps operating costs under control with an efficiency of up to 90% by returning power to the grid.

SL1007A Power electronics

The SL1007A cell test system has high regeneration capabilities, allowing highly efficient, cost-effective, and environmentally friendly operation. Thanks to the bi-directional power supply, up to 90% of the discharge energy is fed back to the mains.

The SL1007A includes safety features within the power electronics preventing overheating, overcharging, short-circuiting and open-circuiting. It also has reverse polarity protection and monitors all internal voltages, currents, and temperatures. In the case of an emergency shutdown, contacts on the mains ensure that there is no voltage, and all internal high-voltage sources are automatically discharged.

The SL1007A is a Complete Cell Test System

The SL1007A provides electrical charge, discharge, and measurement capability for the cells you are testing. You can select current capacities ranging from ±25 A to ±600 A and the number of test system channels from 4 to 64 channels.

In a cell test application, the SL1007A will typically be combined with additional system resources, including test system software, contacting, and fixturing for your cells, cables, environmental chambers, and redundant safety systems. The user or Keysight can provide the supporting equipment. Keysight can combine and integrate all the components to create a test solution. Contact Keysight to discuss complete customized test solutions incorporating one or more of these additional components that will meet your specific test needs for the number and types of cells you require.

Electrochemical impedance spectroscopy

You can gain deeper insights into the characteristics of your cells with the optional electrochemical impedance spectroscopy (EIS) capability. SL1007A provides integrated electrochemical impedance spectroscopy measurements per test channel, independently programmable within a test sequence. Multi-sinusoid excitation delivers faster results. Find out more below.

Parallel channels to increase current

You can increase the total current/power for a cell being tested by manually connecting channels in parallel, outside of the system cabinets. Up to 16 channels with identical current can be connected in parallel for up to a maximum total current of 1600 A. For example:

• Up to 16 channels rated at ±100 A channels can be connected in parallel to provide up to ±1600 A.

• Up to five ±300 A channels can be connected in parallel to provide up to ±1500 A.

• Up to four ±400 A can be connected in parallel to provide up to ±1600 A.

The Energy Storage Discover software allows you to define groups of channels that have been connected in parallel, so they may be treated as a single channel for programming purposes.

Note: For SL1007A configurations with two cabinets of power electronics (see the configuration table on page 6), channels from the power electronics in one cabinet cannot be connected in parallel with the channels from the power electronics in the second cabinet.

Reference electrode connection

You can connect up to three electrodes per channel to allow voltage measurements between positive, negative and a reference electrode. This allows performing cyclic voltammetry measurements. The measured values allow a separate analysis of the cathode's or anode's behavior, which helps to understand the performance of the overall cell in more detail.
