The true modular structure of the BaSyTec Battery Test System makes customization of the system easy and economic. Based on the standard 19 inch rack system, all modules are plug-in type. One benefit of this is that you can start with a small system, and easily grow the system as your budget allows. In addition, this modularity minimizes maintenance costs, and with only one (1) test channel per module, allows maximum system integrity. Each system is operated through a standard PC computer, which can be supplied by the user if preferred. Both RS232 and Ethernet communications are available, between the test system and PC.

Central Processor Unit (CPU) - Each system contains one or more CPU modules, depending on the number and type of test channels.

Test Channel Cards - These are available in various standard voltage and current ranges, with the capability to mix different voltages and current ranges in the same system. Each test channel operates independently, allowing different tests to be performed at different times on the same system. Four (4) wire Kelvin type battery connection. Four (4) additional analog inputs standard for each channel, for use as reference electrode, temperature (Pt100), pressure, humidity, pH etc. Low current systems, typically used for Research and Development applications, are normally supplied in a bench mounted case, with up to 9 test channels per 19 inch rack. Higher power systems are normally supplied in a floor standing rack cabinet, with size depending on the number of channels and the application.

Digital I/O Card - With or without relay contacts. For use with lights, push buttons, or external control systems.

External Charge/Load Card - To allow integration of external chargers or external DC loads in the testing process.

Examples where high speed is necessary:

• Simulation of a power tool load profile
• Pulse charging
• PWM load simulation
• Digital camera load simulation
• Complex and fast load profiles
• Battery parameter deternination
• Impedance measurement with ptionImpedance

The control loop and the data acquisition of the tests systems are optimised for high speed dynamic tests. The rise time of the systems is typically 10 us in case of unipolar and bipolar pulses. The time resolution is 160 ns and data sampling of voltage and current is done in a synchronized mode.

Preferred operation is under Microsoft Windows 2000 or XP. Once tests are started, the test system operates automatically, with or without supervision. The sequence of system operation is quite logical.

Write a Test Plan - Line oriented test plan, with a simple to understand and easy to use editor. Uses direct keyboard entry with assistance from wizards.

Start a Test - Individual channel or a group of channels can be started simultaneously, with the possibility to perform a time delayed start.

Monitor in Real Time - A single detailed screen displaying real time data and real time graphics is provided, essential for use in short term electrochemical experiments.

Record Data - Test data is recorded at user specified intervals into a local SQL database in the system PC. This database system makes it simple to identify tests, and to get all information relating to the test, whether the test is still active or was completed a long time ago.

Analyze Data - The integral data analyzing tool makes it possible to analyze data from both active and completed tests. Analysis can be performed numerically using powerful filters, or graphically, and can be used to generate professional reports.

Export Data - For some larger users, the capability to export test data to the company's internal network is provided.
