High Power Battery Test System (HPS)

General

The HPS series is optimised for a power range of 100W to 30 kW. The modular concept of the power amplifier makes the system in a wide range configurable. The key features are:

• Currents up to 500A/channel
• Parallel connection of channels is possible
• Voltages up to 60V
• Rise time < 1 ms
• Truly modular design provides complete flexibility and cost efficiency.
• Additional analog inputs standard
  (for reference electrode, temperature etc.)
  four (4) per channel
• Native (analog) CC and CV operating modes
  Allows precise, high speed control through zero.
  Other modes operate under digital control.
  
• High speed control and data acquisition
  To meet today's pulse profile requirements
  
• From 1 to 400 independent channels per system
  Provides flexibility for any size of user
• Local database
  No need to export data to perform analysis
• RS232 or Ethernet communication
  At user's option
• Network compatible
  Allows one or multiple systems to be easily
  connected to the user's in-house network.
• Direct integration with other types of test systems
  For example, load control in fuel cell test systems
• Enhanced numerical/graphical analysis and report generation
  The most features and professional presentation
  available.

Technical data

Applications

The BaSyTec high power battery test system is optimised for high power and high current applications where accuracy and high speed are of special interest. Some examples are:

• Automotive batteries (SLI)
• Electric vehicle
• Electric hybrid vehicle
• Fuel cell applications
• Stationary batteries
• Power Tools

General concept

The BaSyTec high power and high current  battery test system is of a modular design. Each test channel consists of a cpu board, a data aquisition board, a control board, and a fast power amplifier. The power amplifier is based on parallel connected power modules. The number of power modules depends on the  power of the test system. Test systems with a power of some 10 kW are possible. The ethernet interface makes modular system expansion possible. Up to 100 test channels can be operated with one computer using the BaSyTest battery test software.

High Speed

• cranking tests
• drive cycles
• power tool profiles
• pulse charging
• battery parameter deternmination

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.

Advantages of the modular structure

The modular system has the following advantages:

• Short manufacturing times
• Cost reduction
• High reliability and high quality
• Maintenance friendly
• Modular system expansion (up to 100 channels)
• Guaranteed specifications

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.

BaSyTest Control Software

The BaSyTest Software is a universal and powerful tool to control all BaSyTec battery test systems. All data is stored in a database system. The fast numerical and graphical data analysing and the direct data transfer to MS Excel and MS Word makes the software to the most powerful one in the market.
