Test Systems for Research, Development and Production

Overview of our test systems by voltage and current range

The figure shows the voltage and current ranges of the different battery test system series. XCTS, MRS and RPS are based on switched power supply amplifiers, resulting in a high energy efficiency and low heat generation.

MDS and GSM Series

Systems of the MDS and the GSM series are designed for highly dynamic testing. The MDS series is for voltages between -10 V to +10 V at currents of 25 mA optimized. The GSM series is for voltages between -0.5 V and + 10 V at different currents (up to 120 A) designed.

LPS: Test Systems with small Power

Systems of the LPS series are customized designed in voltage and current range. The linear amplifier can work up to 70 V and 60 A. Additionally each test channel can be equipped with up to 4 auxiliary inputs according to your requirements (for example 2 * PT 100 and 2 * voltage).

Cell Test System (CTS):

The CTS test systems are designed for single cell tests with voltages up to 5 V (6 V) and currents up to 5 A. The very compact design allows a standard table top system with 32 independent test channels. Each channel has an additional measuring input for the cell temperature.

XCTS: Extended Cell Test System

The test systems of the XCTS series are designed for single cells with a maximum voltage of 4.5 V and currents of 25 / 50 A. The amplifiers are based on switched power supply principles what results in low heat generation, compact design and high overall energy efficiency. Up to 6 channels can be operated in a parallel mode, resulting in 300 A charge and discharge current for a single cell.

MRS: Cell Test System for very high Currents

The MRS cell test system is for maximum currents of 100 to 900 A designed and optimized for single cells (voltages up to 6 V). The switched mode design of the amplifier results in a high efficiency, low heat generation and compact design.

HPS: Test Systems for high Power

Test systems of the HPS series are based on a highly modular amplifier design. Voltage and currents can be adapted to your requirements. Currents up to 600 A, voltages up to 70 V and a maximum power of 6 KW are possible for a single channel. Additionally the power and current can be increased by parallel connection of up to 4 Channels (Up to 2400 A). As an option there are up to three current ranges for one channel possible and an independent battery safety device (BSD) can be integrated in the test system.

MRS Module Test System

The MRS module test system is designed for voltages of 70 V and fits the typical module size. Maximum currents are customized between 70 A and 540 A. The switched mode amplifier results in low heat generation and high energy efficiency. This also reduces the energy demand for cooling of the battery laboratory.

RPS: Battery Pack Tester

The RPS Battery Pack tester is for voltages up to 1000 V and currents up to 1000 A and a maximum power of 500 kW. A Battery safety (BSD) is integrated in the system and many additional options are possible.

Test Systems for Workshops and Service Stations

BCT: Battery Capacity Tester

The BCT is doing a discharge test, beginning from a fully charged battery, until the end of discharge voltage is reached. The discharged charge amount and energy amount are displayed as absolute values or as relative values (related to the nominal capacity / nominal energy. An integrated database allows to store battery types including there parameters. A visualization and a report generation can be done with an optional computer software.

Options and Accessories

CMU: Cell Monitoring Unit

The Cell Monitoring Unit is a data acquisition system for up to 480 voltages and/or temperatures of cells and modules. The data acquisition is synchronized with the data measured by the connected test system, are stored in the same data file and can be used to control a test. The signals of the CMU can be distributed between different test channels.

BSD: Battery Safety Device

The BSD is an independent measuring system that is continuously measuring the battery sigals (voltage, temperature). If one of the signals leave the threshold values, the test is stopped in a controlled way and the battery is disconnected from the test system. The BSD can detect safety critical situations an damage of the device under test can be avoided. Additionally the signals of the BSD can be used in the test schedule and registering of them is possible, too.

Battery Holder

We offer a wide variety of contacting systems for cells of different sizes. This systems give a reproducible connection between the battery and the cable.

SSMS: Superior Safety Monitoring System Interface

The SSMS is an interface for a multilevel safety concept including nitrogen flooded test chambers.

Client Server Database Module

The client server database module allows to mirror all data of several test systems on a central database (MS SQL). The data backup can also be reached from other computers in the network and data analyzing with other tools (simulation software or spreadsheet software) can be done.

EIS: Electrochemical Impedance Spectroscopy

The EIS is a method for:
– determining the structure and parameters of battery models
– Investigating electrochemical reactions
– Determination of the battery state of charge
– Determination of the battery state of health
