| Product name | Battery pack bottom impact tooling |
| Product model | HT-CD-1128 |
| Control method | Remote computer control + video surveillance |
| Impact direction | Remote computer control + video surveillance |
| Bombardment energy | The 50j-800j is adjustable |
| Impact energy accuracy | Measure the ± 1% of the constant value |
| For example: Impact energy 50j * ± 1%= precision ± 0.5j; | |
| Impact energy 800j * ± 1%= precision ± 8j | |
| Principle of energy regulation and control | According to the weight of the impact weight and the energy requiring impact j (joule), the software automatically calculates the impact speed; the computer remotely controls the servo motor transmission speed of the impact tooling, and thus realizes the upward impact energy control |
| Impact head | 1. Customize the impact head size and quality according to the requirements; |
| 2. Preparation: Hemispherical impact weight, diameter of 25mm, material of # 45 steel, weight of 10kg~40kg | |
| Impact direction | The z-axis of the bottom of the battery pack is vertically upward |
| Impact position | The weakest place at the bottom of the battery pack (with the geometric center of the installation point of the power battery pack as the origin, select a point within the radius of 240mm for impact, the manufacturer shall provide proof that this point is the weak point) |
| Impact release mode | The servo motor controls the shock release |
| Prevent secondary shocks | The release mechanism has the function of preventing the secondary impact to prevent the secondary rebound impact of the impact head on the battery pack |
| Sample fixed | The battery is packed into the ball strike bracket fixture of the original ball strike pin testing machine |
| Impact tooling fixed | 1. Before the installation of the battery pack, it is necessary to impact the bottom plate of the load load inside the support with the aerial crane, because the beam with the impact load height higher than the ball support cannot be pushed horizontally |
| 2. The bottom of the impact tooling is designed with heavy universal casters and leveling foot to adjust the impact position and fixation | |
| Remote control positioning | The remote control controls the ball head to locate the impact point at the bottom of the battery pack |
| Impact data acquisition | Impact speed; impact time |
| Equipment operation safety reminder design | The equipment is equipped with three-color alarm lights to remind the personnel of the current test operation status of the equipment. Avoid misoperation during running time |
| Source | Ac 380v50hz |
| Aggregate capacity | 8kw |
| Outline dimension | Size of host: W800 * d800 * h1750mm (subject to design) |
| Weight of equipment | Host weight is about: 500kg |
| Equipment installation conditions | (1) installation and in place: The equipment can be unloaded through a 2-ton forklift truck and moved into the laboratory truck |
| (3) the ground of the impact host is 1000 kg/m3. The ground should be flat. | |
| (4) laboratory lighting is good, convenient and clear camera monitoring equipment. | |
| (5) the passage of the laboratory to facilitate the transportation of battery packs or vehicles and related transportation vehicles. In case of a special emergency situation, the personnel can be scattered away in time | |
| (6) the laboratory should be equipped with the corresponding fire fighting facilities to facilitate the use of its fire fighting tools. Such as fire water, fire extinguishers..., etc | |
| (7) the laboratory needs to be equipped with aerial cranes to facilitate impact loading and battery packs. The lifting height is 3m |
