SL1007B Battery Test System Cell Level

The SL1007B 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 SL1007B 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.

Our purpose-built Energy Storage Discover software helps you automate common compliance, endurance, and performance tests. The system hardware provides excellent accuracy, ensuring precise capacity, efficiency, impedance, 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, 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.

In a cell test application, the SL1007B will typically be combined with additional system resources, including test system software, fixtures 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 completely 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.

You can gain deeper insights into the characteristics of your cells with the optional Electrochemical Impedance Spectroscopy (EIS) capability. SL1007B provides integrated electrochemical impedance spectroscopy measurements per test channel, independently programmable within a test sequence. Multi-sinusoid excitation delivers faster results.

You can increase the total current/power for a cell being tested by manually connecting channels in parallel, outside of the system cabinets. For example:

• Up to 32 channels rated at ±100 A channels can be connected in parallel to provide up to ±3200 A.
• Up to eight ±400 A channels can be connected in parallel to provide up to ±3200 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. You can connect up to three electrodes per channel to allow voltage measurements between a positive, a 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 overall cell's performance in more detail.
