1. Definition of battery heavy object impact testing machine
The battery heavy object impact testing machine is a special testing equipment that simulates the impact of heavy objects on batteries during transportation and use. It is mainly used to evaluate the safety performance of batteries under mechanical impact. This equipment uses standardized testing methods to detect whether the battery will undergo dangerous situations such as fire and explosion.
| Core parameters | Typical values |
|---|---|
| Impact weight | 9.1kg±0.1kg |
| impact height | 610mm±25mm |
| Impact surface diameter | 15.8mm±0.1mm |
| Test temperature | 20±5℃ |
2. Working principle and testing process
1.How it works:The standard weight is raised to a predetermined height through an electromagnetic or mechanical lifting device and then released, allowing it to fall freely to impact the battery sample.
2.Test process:
| steps | Operation content |
|---|---|
| 1 | Battery sample preprocessing (fully charged) |
| 2 | Fixed at the center of the test platform |
| 3 | Set impact parameters (weight/height) |
| 4 | Perform shock testing |
| 5 | Observe and record reactions (24 hours) |
3. Industry applications and standard requirements
This equipment is widely used in new energy vehicles, consumer electronics, energy storage systems and other fields, and mainly follows the following standards:
| Standard number | Scope of application |
|---|---|
