The AVL Stingray™ Testbed is designed for rapid and effective fire suppression in battery testing environments. The system comprises two main components:
- Punch Unit: Penetrates the battery, enabling direct access for the cooling fluid. Typically positioned inside battery-electric or hybrid vehicles during testing, it can also be used for standalone battery packs. Powered by compressed media, it precisely targets the battery through the vehicle floor.
- Trolley Unit: Houses the control system and technical equipment, ensuring seamless operation and mobility.
Key Features and Benefits
- Direct Battery Penetration: Enables efficient cooling by accessing the battery through the vehicle floor.
- Versatile Application: Suitable for both in-vehicle and external battery testing.
- Fast Installation: Ready for operation in approximately 2 minutes.
- Scalable Solution: Supports up to two punch units simultaneously for larger or multiple battery setups.
- Flexible Cooling Options: Compatible with water or liquid nitrogen for targeted temperature control.
- Adaptive Operation: Offers both manual and automatic activation, ensuring flexibility in emergency situations.

Design and Construction
The AVL Stingray™ Testbed consists of two main components: the punch unit, which penetrates the battery to allow direct access for cooling, and the trolley unit, which stores the technical equipment and control system. Its compact and versatile design makes it easy to integrate into various 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 is typically placed within the battery-electric or hybrid vehicle during testing but can also be mounted directly on external batteries. For larger setups or when testing multiple batteries, you can install up to two punch units simultaneously.
Quick Setup & Flexible Operation
Installation time is approximately just 2 minutes, ensuring that the system is ready for use with minimal delays. The system can be activated either manually or through testbed automation, providing flexible operation while maintaining the highest levels of safety throughout the testing process.

Battery safety on powertrain testbeds has long been an unpredictable risk. With the launch of the AVL Stingray™ Testbed, this danger has now become a challenge that can be managed.”
