Description

Technical Field

[0001] The utility model belongs to the technical field of battery pack testing, and particularly relates to a high-voltage battery pack testing tooling. Technical Background

[0002] High-voltage battery packs generally need to be tested for discharge performance. High-voltage test cabinets are the most common testing tools, but high-voltage test cabinets are relatively expensive. Some enterprises do not have them configured, or small-batch testing does not require high-voltage test cabinets for testing. Currently, when high-voltage test cabinets are not used, high-power resistors are generally used in series with a switch for control testing, which has the risk of damaging battery pack components and resistors, (and there has been a situation where the tooling switch was burned out), and testers are also prone to electric shock risks. Content of the Utility Model

[0003] The utility model provides a high-voltage battery pack testing tooling, which can solve the problems pointed out in the background technology.

[0004] A high-voltage battery pack testing tooling includes a fixing plate, a high-voltage resistor, a high-voltage-resistant relay, positive and negative test terminals, a low-voltage battery, and a control switch. The high-voltage resistor is connected in series with the high-voltage-resistant relay, and its positive and negative poles are respectively connected to the positive and negative test terminals. The low-voltage battery is connected to the high-voltage-resistant relay to supply power to the testing tooling, and the control switch is used to control the low-voltage battery.

[0005] Preferably, the low-voltage battery is a 12V battery.

[0006] Preferably, the positive and negative test terminals are test clips.

[0007] Beneficial effects: The utility model provides a high-voltage battery pack testing tooling, which uses weak electricity to control the conduction of strong electricity, without direct contact, reducing the risk of component damage and facilitating safer operation for testers.
