AVL Stingray™ Testbed

Limit potential fire damage with our battery safety system.

Even in the event of an unexpected fire when working with batteries, you can remain confident: With AVL Stingray™ Testbed, the situation is under control.

AVL Stingray™ Testbed

Battery testing on modern testbeds faces a variety of safety problems. The most common method of suppressing a battery fire or thermal runaway incident is to flood the testbed with enormous amounts of water to cool the battery to safe levels. This often leads to the damage or destruction of electrical equipment, test cell environment and is therefore far from ideal. We have developed a unique battery safety system to combat this issue. This revolutionary system instantly addresses the source of the fire. This cuts down both the amount of cooling liquid required as well as the cooling time.

Battery prototype testing can involve risks - the biggest being fire outbreaks. This can mean danger to employees and equipment. In addition to precautions that protect people, with Stingray there is now also the possibility to protect equipment and entire test premises from damage in the event of fire.  Therefore, should the case of fire occur during test operations, Stingray is ready - so you can do your work safely and relaxed.

AVL Stingray™ Testbed
Reduce Cost in Case of Damage

The common method of extinguishing a battery fire or thermal runaway leads to the damage or destruction of a testbed.

Superior Fire Extinguishing

Unlike other methods, this revolutionary system instantly
goes to the source of the fire by penetrating the battery.

Broad Applicability

Which makes it convenient to use on a variety of different testbeds.

Easy Operability

The system is small, compact and versatile and has been designed with usability in mind, which also reduces the need for training.


The system consists of two main parts: A punch unit that penetrates the battery, allowing access for the cooling fluid, and a trolley that stores the technical equipment and control unit. The punch unit generally sits within the battery electric or hybrid vehicle during testing but can also be used for external batteries. Powered by compressed media, it aims directly at the battery through the floor of the vehicle. For larger or multiple batteries, you can install up to two punch units.

  • Penetration of the battery through vehicle floor
  • Useable at internal and external batteries
  • Time to install approx. only 2 minutes
  • Possibility of using two penetration units simultaneously
  • Cooling of the battery with water or liquid nitrogen
  • Possibility of manual or automatic release

Should an accident occur – for example, if the battery starts burning or reaches uncontrollable temperatures, our new system provides a unique, highly effective battery cooling method for when tests go wrong, improving the safety for all involved.

Save Time and Costs

Reduces the impact on a testbed, making the aftermath of an accident less drastic. Testing can begin again sooner after an incident occurs.

Highly Efficient

The system goes to the source of the fire. This cuts down the amount of cooling liquid required and the cooling time.


The system is small, compact, and versatile, which makes it convenient to use on different testbeds. For larger batteries, two punch units can be installed.

Design and Construction

The system mainly consists of only two parts: A punch unit that penetrates the battery and a trolley that stores technical equipment and the control unit. It is compact and versatile, which makes it convenient to use on different testbeds.

Efficient Cooling

The system instantly goes to the source of the fire. This cuts down the amount of cooling liquid required as well as the cooling time. It also reduces the impact on your testbed.

Multiple Punch Units

The punch unit sits within the battery electric or hybrid vehicle during testing or is mounted directly on an external battery. For larger or multiple batteries, you can install up to two punch units.

Quick Installation, Multiple Operational Modes

Time of installation required is approximately only 2 minutes. Therefore, almost no time delay. The activation of the system can be done manually or via testbed automation. This ensures maximal safety whilst testing.

AVL Climatic Chamber

Battery packs, modules and cells, fuel cells, e-motor and e-axle solutions must operate safely and reliably in any environment. This can include extreme temperatures and humidity, which cannot be reproduced on the test track or in real test scenarios on the road. This is why we developed the modular AVL Climate Chamber.

Test Systems for battery cells
AVL Battery Cell TS™

For battery cell testing, we offer complete test systems, stand-alone equipment, or even entire turnkey test labs.

AVL Battery Module/Pack TS™

We offer complete test systems for the testing of modules/packs. Learn more about which hard- and software products are included in our test systems.
