Lithium Ion - 2

Safe testing In the field of mobile systems, lithium batteries have successfully proved their importance as energy storage. Ever larger applications - such as electric vehicles - require storage systems, which not only offer a large volume of energy, but which also can produce large outputs. To test their reliability, lithium batteries are subjected to various tests in the field of environmental simulation. These tests are carried out in temperature change test cabinets or climatic test chambers. During the temperature tests, overchargings or malfunctions of the batteries may occur. This...

Safety options Status display The signal lamp can be positioned variably on the device due to an adjustable magnetic foot. The red signal lamp flashes when a fault occurs. In addition, an acoustic signal is possible. Reversible pressure release flap Reversible Druckentlastungsklappe The venting duct is installed on the top of the cabinet. It is equipped with a mechanical, weighted Der Druckausgleichsstutzen bzw. Abluftstutzen pressure release flap. This can installiert.

Mechanical door lock Two fasteners which mechanically hold the door closed are attached to the test space door in addition to the reversible pressure release flap. Sealing plug and retaining clamp The entry ports are equipped with retaining clamps to secure the plug. Fire detection via temperature measurement Fire is detected by an independent, freely-movable PT 100 temperature sensor. The sensor records temperature increases which are possibly caused by fire inside the test cabinet.

Safety options Permanent inerting using nitrogen or argon The door lock is activated for permanent inerting of the test space with nitrogen (N2) or argon (Ar). A major flushing quantity reduces the oxygen concentration to ≤ 5%. After the minimum flushing time has elapsed, testing is released and the system switches to a process-orientated small flushing quantity. Oxygen measurement In combination with the permanent inertization using nitrogen or argon, the oxygen (O2) measurement is used to monitor the O2-concentration in the test space. It allows a controlled infeed of nitrogen or argon....

Lithium Ion - 7

Flushing device for inertization in case of fire When a fire is detected, the test space can be flooded with nitrogen (N2) or carbon dioxide (CO2). This flooding inertizes the test space and with liquid CO2 also has a slight cooling effect. CO2 compressed gas bottles As an addition to the flushing device for inertization in case of fire, a compressed gas bottle, filled with 7.5 kg CO2 and an aromatic additive, is attached to the side of the test cabinet. The CO2 is filled into the test space in a liquid state. When it expands, cold gas and CO2-snow is formed. Several bottles can be...

Temperature test cabinet for testing cells and packs Temperature and climatic test cabinet for testing cells, packs, modules and complete batteries The temperature change cabinet 2xVT 4021/S was developed specially for testing cells and packs in laboratories. The superimposed test spaces, each with a capacity of 210 litres, permit simultaneous execution of two tests, but only require half of the laboratory space that two comparable single-chamber solutions would require. Of course, the entire VT series can be equipped with safety options for testing lithium batteries. This cabinet is...

Stress Screening systems for testing cells, packs, modules and complete batteries XXL series for testing batteries The VTS³ and VCS³ temperature and climatic test systems fill the gap between the tried-and-trusted temperature and climatic test systems of the VT³ and VC³ series and our shock test systems. With test space sizes from 190 to 1540 litres and a temperature range from -70 °C to +180 °C, we are able to meet nearly all customer requirements. The VCS³ series implements common climatic testing standards. The preferred temperature change rates are 5 K/min, 10 K/min and 15 K/min. For...

Temperature and climatic test chambers for vibration tests Walk-In and Drive-In Climatic Chambers for testing vehicle batteries Our temperature and climatic test chambers of the VTV³ and VCV³ series are designed for the temperature and climatic overlaying of a dynamic vibration system. The impact of vibration tests can be investigated on products from cells to batteries under different climatic conditions. The test chambers, based on the tried-and-trusted modules of the Stress Screening system, are available with increased performance of heating, cooling and circulating air and with test...

Systematic Communication More control in shorter times Our test systems equipped with safety devices for testing of energy storage systems can be integrated perfectly into your existing testing area, just like any other test system made by Vötsch. Our test systems are equipped with a colour touchpanel as standard. The menu-guided desktop means that the tasks of the single performance components can be co-ordinated and monitored. Process sequences, system conditions and other process images are presented as graphical, self-explanatory pictograms. This makes use even more intuitive. Up to 100...
