| 1.04 | Automatic Fire Extinguishing Function: When the battery pack catches fire, it can be automatically or manually controlled by computer to move the battery pack to the water pool surface for fire extinguishing; the equipment is equipped with a self-moving installation and a stainless steel water tank |
| 1.05 | Vertical Upward Impact, Ball Impact, Needle Impact |
| 1.06 | 80J–1000J Adjustable |
| 1.07 |
80J–150J: Accuracy ±2% 150J–1000J: Accuracy ±3% The energy of the 10kg impact ball is calculated by the computer control software, and the software automatically calculates the impact speed. The remote computer controls the transmission speed of the servo motor of the impact tool to realize the upward impact energy control. |
| 1.08 |
According to the weight of the impact weight and the required impact energy (Joule), the software automatically calculates the impact speed. The remote computer controls the transmission speed of the servo motor of the impact tool to realize the upward impact energy control. 1. Customize the size and quantity of impact heads according to requirements. 2. Standard configuration: Hemispherical impact weights, with diameter sizes of φ25mm and φ30mm (replaceable), material is #45 steel, weight 10kg. |
| 1.09 | Vertical upward impact in the direction of the battery pack bottom |
| 1.10 | The weakest part of the battery pack bottom (taking the geometric center point of the power battery pack vehicle installation point as the origin, select a point within the radius of 240mm area for impact, and the manufacturer is required to provide the material weak point) |
| 1.11 | Servo motor controls the impact point |
| 1.12 | The release mechanism has a function to prevent secondary impact, preventing the impact head from rebounding and impacting the battery pack twice |
| 1.13 | The battery box is installed on the impact ball fixture of the original impact needle testing machine |
| 1.14 |
1. Before installing the battery pack, use a hoist to first hoist the impact tool into the bottom plate inside the impact ball support. Because the installation height of the impact tool is higher than the beam of the impact ball support, it cannot be inserted horizontally. 2. The impact tool is designed with universal wheels in the weight direction and an adjustable level to adjust the impact position and fix it. |
| 1.15 |
(1) Software acquisition speed: The maximum acquisition frequency of output data is 30KHZ (2) Testing hardware: The frequency of the displacement sensor is 200kHz; the test speed range is 5–5M/s, and the accuracy of this sensor is ±5MHz. This sensor is fixed together with the impact ball/needle, and can read the full-range speed data: static – dynamic impact – impact rebound – static. (3) Energy compensation: When the impact head moves upward to impact the battery pack bottom, if there is a certain distance in the process, this distance can be input into the software, and the software automatically compensates the energy. |
| 1.16 | Motion laser positioning: Equipped with 1 laser alignment device, which can be quickly installed on the machine head by itself. With mains power, turn on the power switch to emit an infrared cross cursor to align the bottom of the battery pack upward for positioning ball impact; needle point. |
| 1.17 | The equipment is equipped with three-color warning lights and prominent signs, and the trial operation status and operation status of the equipment are operated remotely. |
| 1.18 | 8 kW | AC380V 50Hz |
| 1.19 |
Impact host external dimension: W800 × D800 × H1750mm (subject to design) Ball impact needle automatic machine external dimension: W800 × D800 × H1750mm (subject to design) |
| 1.20 | Automatic fire extinguishing tooling: Subject to design only |

FAQ
-
Needling will directly puncture the battery separator, causing a large-scale internal short circuit. It will instantly release a large amount of heat and quickly trigger a chain reaction of thermal runaway. Our equipment precisely controls the depth and speed of the needle insertion, helping engineers analyze the thermal stability of the battery under different conditions.
-
Taiantest adopts the technology of "electromagnetic attraction + pneumatic disengagement", combined with precise displacement sensors. The height error of the falling ball is controlled within ±2 mm, fully meeting the requirements of the UN 38.3 heavy object impact test.
-
The bottom of the explosion-proof warehouse is equipped with a dedicated drainage channel and an easy-to-clean tray. The exhaust system can be connected to a laboratory purification device, which filters out harmful gases such as hydrogen fluoride (HF) before being discharged.
-
The standard configuration supports an impact energy range of 80J to 1000J, which is fully adjustable. The energy accuracy is ±2% for 80J–150J and ±3% for 150J–1000J. Custom impact head sizes, weights, and quantities can be configured based on specific testing requirements.
-
When a battery pack catches fire during testing, the system can be triggered automatically or manually via computer control. It moves the battery pack to the surface of a built-in stainless steel water tank for immediate fire suppression. The equipment also supports CO₂/nitrogen fire extinguishing interfaces for additional safety layers.
