OUR SERVICES

The test benches for all types of battery and environmental tests

Battery dimensions

We can test cells, modules and packs under almost any conceivable test scenario. Our test facility is designed to meet individual customer requirements, from cells to large battery packs. We are at your disposal for specific inquiries.

Dimensions

We are also able to test larger batteries up to approx. 2m x 1.5m, such as those from forklift trucks or buses.

Weight

Depending on the test, tests on heavy battery systems weighing up to 1,200 kg are also possible without technical restrictions.

Performance

Our electronics offer up to 350 kW (or 1,000 V) of power.

Sample test

From prototype to D-sample

OUR TEST BENCHES

Our test benches offer precise and reliable test solutions for a wide range of applications. With state-of-the-art technology and comprehensive expertise, we guarantee detailed analyses and the highest quality for your testing requirements.

Battery and cell tester

For carrying out cycle and performance tests as endurance tests.

Test benches

Various other test benches, such as crushing or IP testing.

Vacuum chamber

Our negative pressure chamber can be used to simulate altitude.

Climate and temperature chambers

Climate and temperature chambers in various sizes.

Shaker und Shock

TEST EQUIPMENT

Batteryuniversity GmbH's test benches can be used to test large batteries for electric cars or electric forklift trucks. The BU is therefore well positioned for battery tests in the field of electromobility and can also test any components, e.g. from the aerospace sector.

SHAKER / SHOCK

The BU's 160 kN shaker can be loaded with a weight of up to 800 kilograms and can test noise profiles, sliding sine waves, superimposed sine waves and shock pulses. The shaker's headexpander and sliding table have a clamping area of 1.5 x 1.5 meters. The frequency can be varied from 5 to 2,500 Hz.

Shaker

up to 160 kN
Mounting table for test specimens up to 1.5 x 1.5 m
Test specimens weighing up to 1,100 kg

Shock

150 g
Half sinus

LARGE PRESSURE/VACUUM CHAMBER

The vacuum chamber with a size of 8 x 3 x 3 m enables the testing of huge battery units or other components. The control system can be used to program any profile down to a low pressure of 1 millibar.
