Nail penetration, crush, and

external short circuit test systems

ADST series

The final word in cell safety test systems, with one system able to perform 4 different tests
A lineup of large-size safety test systems for a wide range of battery packs is also available

Modules have been created that contain the test functions necessary for cell nail penetration, compression, eternal short circuit, and overcharge and forced discharge tests. This makes it possible to construct a system composed of a single safety test temperature chamber equipped with the necessary combination of functions.

Features

Support for a variety of test standards by changing the holder jig!

There are a variety of test standard requirements for crush tests, and the test conditions span a large range.
Crush holder jigs utilize a chuck structure for changeable jigs, allowing the system to be used for many different tests.
At the nail penetration test, because the nail shape and material will affect the test results, tests can be performed using a variety of different nail types.

A resistance adjustment function to support a variety of test standards

There are a variety of test standard requirements for external short circuit tests, and the test conditions span a large range. By providing a resistance adjustment function, it is possible to adjust the short circuit resistance according to the test conditions.
The resistance fine adjustment function can also be used to create a reproducible test environment for changes in circuit resistance that occur as a result of aging.

Nail penetration tests of battery packs are also supported.

Nail penetration tests of large-size battery packs are also possible.
The motorized elevating specimen stage makes it possible to conduct nail penetration tests in the vertical direction.
The structure that is integrated with the temperature chamber allows tests to be performed in actual temperature environments.
Specimen stage dimensions: 2000×2000 mm
Temperature range: -40°C to +80°C

Crush tests of battery packs are also supported.

Crush tests of large-size battery packs are also possible.
These are lateral-type crush test systems that simulate the compression directions that can occur with an on-board battery pack.
Changing the holding jig makes it possible to also conduct nail penetration tests in the horizontal direction.
Test area dimensions: 2000×2000 mm
Load: Maximum 1000 kN, continuous 100 kN
Speed: 0.01 to 1.5 mm/sec

External short circuit tests of battery packs are also supported.

External short circuit tests of large-size battery packs are also possible.
Standard tests and tests in actual temperature environments can be conducted for a wide range of on-board battery packs.
Applicable battery voltages: Maximum 500 V
Short circuit current: Maximum 24 kA
Short circuit resistance: 5 mΩ or less
Temperature range: -40°C to +80°C
