1 GENERAL DESCRIPTION
This technical specification is to describe the technical characteristics of the battery test set
BTS200 MKII, designed for the test of battery benches using the discharge method. This testing
device can discharge the battery in different modes, to measure the capacity of new and used
battery. With respect to the former BTS200, the MKII uses a technological improvement, that has
allowed to reduce weight and dimensions.
BTS200 MKII allows the connection to up to nine auxiliary modules type ELU200 MKII (or
ELU200, or other BTS200 MKII, or other BTS200), that enhance the discharging capability.
With the optional current clamp, or with the external shunt, it is also possible to use the real
burden as the additional burden, and to control the total discharging current in the selected mode.
The device is microprocessor based. This allows the control of all the discharging parameters in
real time. It also allows communication with a PC for the control and the data representation of the
discharging parameters. The following is the test set picture.
With respect to the former version, MKII features the following improvements.
The weight has been decreased of 9 kg, from 48 kg to 39 kg.
Dimensions have been reduced, from 283 x 803 x 420 mm (WDH) to 283 x 700 x 420
mm.
Two wheels have been added, to ease the transport.
The number of discharging steps that can be programmed have been increased from 10 to
20: this eases drawing any discharge profile.

In addition to the external clamp, the external burden current can now be measured also
with a shunt.
If a test is interrupted, for instance because of a faulty contact or cell, after the repair it is
possible to continue the test: this was not possible with the former device.
The test set firmware can be upgraded with a supplied software.

3 PERFORMANCE SUMMARY
3.1 Introduction
BTS200 MKII can discharge batteries with different nominal voltages, from 24 V to 240 V DC.
The discharging current can be up to 130 A for voltages of 24 to 120 V DC nominal, and up to 70
A for 220 to 240 V. It is possible to use in parallel up to 10 BTS200 MKII, thus arriving up to
1300 A for voltages of 24 to 120 V DC nominal, and up to 700 A for 220 to 240 V.
The use of BTS200 MKII is very simple:
Connect the cables to the battery to be discharged;
Power-on BTS200 MKII;
Choose the memory area where to save the test data;
Program the discharging current (or power);
Program the maximum discharge duration;
Program the minimum battery voltage;
Program the Ah to be discharged;
Press START.
During the discharge actual parameters are displayed on the graphic screen; all the measured
parameters are saved into the selected memory. It is also possible to connect BTS200 MKII to a
PC with TDMS: this allows to have on the PC display the discharging diagram.
Via PC, it is possible to download a current sequence with up to 20 steps, each step being
programmable in current and duration. This enables simulating a typical current profile
encountered during the day.
If, during the discharge, any of the programmed limits is trespassed, the test is immediately
stopped, and the alarm contact closed.
Once the test is finished it is possible to watch the discharging current and voltage on the display,
or to download the test result to the PC.
The selection of discharging parameters is performed using the encoder with confirmation switch,
and the graphic display. The operation is menu driven: turning the encoder knob it is possible to
select the desired operation; pressing it the selection is confirmed.
Optionally, it is possible to leave an external load connected to the battery under test. In this
situation, the externally discharged current will be measured by means of a DC current probe or
by a shunt: BTS200 MKII takes into account this current, and ensures that the total discharging
current is the programmed one.
The device is equipped with an emergency pushbutton, located on the front. When pressed, it
stops all the BTS200 MKII activities. The pushbutton is mechanically self-locking: the operator
has to rotate it in order to reset the normal operation.
The device can be powered by the battery under test itself, for batteries with a nominal voltage of
220 or 240 V; else, on the front is provided a power supply plug for a wide range AC supply.

NOTES:
1. The above specified current and power ranges apply when the ambient temperature is 25 °C or
less. For higher temperatures, apply a de-rating factor of –1 A/°C for the current; for the power, it
is the product of the voltage by the current scaling factor.
2. The absolute maximum ambient tempperature for full power operation is 40 °C.
3. The test set cannot operate with a direct sun exposition, or located nearby an heat source.
4. The test set generates very hot air, both above and on the rear: don’t touch it until the automatic
cooling down procedure is completed.
