Embodiment 1

[0027] see Figure 1-4 , a kind of BMS test equipment, comprises workbench 4, and the upper surface left side of workbench 4 is provided with test host 7, and the front of test host 7 is provided with display screen 8, and the left side of test host 7 is provided with cooling hole 6, and heat dissipation A fan 5 is provided on the left side of the hole 6, a test bench 11 is provided on the right side of the upper surface of the workbench 4, a signal line 12 is provided between the test bench 11 and the test host 7, and a test button is provided on the front right side of the workbench 4 9 and clamping button 10.

[0028] The four corners of the test bench 11 are provided with guide rods 13, the middle part of the guide rod 13 is slidably connected to the four corners of the supporting plate 14, and the top of the guide rod 13 is slidably connected to the four corners of the support plate 16. 11 is provided with a driving motor 26 in the middle of the upper surface, the output...

Embodiment 2

[0030] see figure 1 , the other content of this embodiment is the same as Embodiment 1, the difference is that: the lower surface of the workbench 4 is provided with a fixed plate 1, the lower part of the fixed plate 1 is connected to the rotating rod 2 in rotation, and the front and rear ends of the rotating rod 2 Fixedly connect the wheel 3. In order to facilitate the movement of the device, wheels 3 are arranged at the bottom of the device, thereby driving the whole device to move through the wheels 3, and a driving device and a braking device can be arranged inside the wheels 3, making the whole moving process more convenient.

[0031]In the implementation process of the present invention, the device is moved to the target position, the device is fixed, and the clamping button 10 is pressed. At this time, the output shaft of the drive motor 26 drives the first bevel gear 27 to rotate, and the first bevel gear 27 drives and The second bevel gear 28 meshed and connected rot...

Abstract

The invention relates to the technical field of BMS testing. The invention discloses a BMS test device comprising a workbench; a test host is arranged on the left side of the upper surface of the workbench; a test board is arranged on the right side of the upper surface of the workbench; a signal line is arranged between the test board and the test host; guide rods are arranged at four corners ofthe test board; the middle parts of the guide rods are slidably connected with four corners of a supporting plate; the upper portions of the guide rods are slidably connected with four corners of thesupporting plate, a driving motor is arranged in the middle of the upper surface of the test board, an output shaft of the driving motor is fixedly connected with a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is fixedly connected with the bottom of a lead screw, and the middle of the lead screw is in threaded connection with the middle of the supporting plate. According to the BMS test device, the supporting plate is controlled by the driving motor to move up and down, so that the clamping work of a movable clamping plate is realized, and after the device finishes clamping, the wiring end of hardware is in contact with a metal contact, so that the test work can be directly carried out.

Description

technical field [0001] The invention relates to the technical field of BMS testing, in particular to a BMS testing device. Background technique [0002] The battery management system (BATTERY MANAGEMENT SYSTEM), referred to as BMS, is the link between the battery and the user. The performance of the battery management system is crucial to the cost, energy saving and safety of electric vehicles. The battery management system can monitor the battery voltage, charge and discharge current, and battery pack temperature, estimate the state of charge of the battery, control battery charge and discharge balance, perform thermal management on the battery pack, and perform CAN (control) with the on-board monitoring system and charger. Local Area Network (LAN) communication, to achieve coordinated control and optimized charging, so that the battery is in the best working condition. [0003] Existing BMS products use connectors to connect with wiring harnesses. In the actual BMS produc...
