The TMC-2001RTS is a portable battery tester for professional testing, maintenance and condition assessment of stationary battery systems. The compact test instrument is particularly suitable for UPS batteries, industrial batteries and safety-critical battery systems, as well as for regularly performed maintenance and capacity tests.

In addition to precise measurement of block and total battery voltages, the TMC-2001RTS enables differentiated determination of the battery’s internal resistance. Both the electrical resistance Rel and the charge-transfer resistance Rct are measured. This allows electrical and electrochemical changes within a battery block to be assessed separately and detected at an early stage.

Advanced Battery Diagnostics with Rel and Rct

A special feature of the TMC-2001RTS is its advanced resistance measurement capability. Unlike basic battery testers, the internal resistance is not considered solely as one overall value.

The electrical resistance Rel essentially represents the ohmic losses within the battery block, for example at terminals, intercell connectors, grids or within the electrolyte. Changes in this value may indicate electrical contact problems or other signs of ageing.

In addition, the TMC-2001RTS determines the charge-transfer resistance Rct. This value describes processes involved in charge transfer between the electrode and electrolyte and therefore enables an additional assessment of electrochemical changes within the battery.

By evaluating Rel and Rct separately, the user obtains a more detailed picture of the battery condition than with conventional internal resistance measurement based on only one measured value.

Measurement Functions for Maintenance and Capacity Testing

The TMC-2001RTS supports various measurement procedures for regular maintenance and testing of complete battery systems:

• Multimeter: direct voltage measurement
• Float charge: recording of individual block voltages during normal operation
• Discharge measurement: repeated recording of block voltages during a discharge process or capacity test
• Charge measurement: monitoring of block voltages during a charging process
• Resistance measurement: simultaneous determination of block voltage, Rel and Rct
• Temperature measurement: measurement of battery temperature using an optional temperature sensor
• Connector test: checking the electrical connections within the battery system
• Electrolyte density: transfer of density and temperature values from an optional DMA35 density sensor
• Interval U: time-dependent recording of the total battery voltage
• Interval U+I: simultaneous recording of total battery voltage and battery current

Fast Measurements Directly On Site

The battery tester was developed for recurring service and maintenance work on extensive battery systems. The menu-guided measurement functions support a structured testing procedure and reduce the effort required when measuring large numbers of battery blocks.

Block voltage, Rel and Rct can be recorded simultaneously within approximately two seconds. If only the block voltage is measured, the measurement time is approximately 0.2 seconds. After completion of a measurement series, the stored values can be checked directly on the instrument, and individual battery blocks can be measured again if required.

RFID Identification and Battery Database

For battery systems that are tested regularly, battery definitions can be prepared in advance and transferred to the TMC-2001RTS before the service visit. The tester can manage up to 1,000 battery definitions.

In addition, the integrated RFID system enables unique identification of battery systems using corresponding transponders. This allows measured values to be reliably assigned to the correct system and helps prevent mix-ups during recurring maintenance work.

CS-Manager Software for Evaluation and Documentation

In combination with the CS-Manager battery management software, battery data, measurement series and maintenance information can be managed centrally. Prepared battery definitions and test tasks can be transferred to the TMC-2001RTS, and the recorded measured values can subsequently be imported back into the software.

Among other functions, CS-Manager supports the management of locations and battery systems, planning of maintenance routes, analysis of measured values and creation of histories and reports. Measurement series can also be exported as CSV files.

The underlying SQL database can be operated either locally on a single workstation or centrally on a server for multiple users.
