Fully automatic connecting device for testing new energy vehicle battery pack

Abstract

The invention provides a fully automatic connecting device for testing a new energy vehicle battery pack. The device comprises a female head adjusting mechanism and a male head automatic connecting mechanism. The bottom of the female head adjusting mechanism is adjustably connected to a battery pack feeding vehicle, and the male automatic connecting mechanism is fixed on one side of a positioningmechanism that cooperates with the battery pack feeding vehicle. One end of the female head adjusting mechanism is connected to a battery pack test harness, and the other end is fixedly provided witha female plug. The male head automatic connecting mechanism is fixedly provided with a male plug, and the connection of the female head adjusting mechanism and the male head automatic connecting mechanism is achieved through the female plug and the male plug. The fully automatic connecting device has the advantages that errors can be maximally absorbed in the three directions of x y and z throughthe adjustment of a male end and a female end, so that the connection process is quick, stable and efficient, and the precision can be controlled within 0.15 mm.

Description

Technical field [0001] The invention relates to the field of battery testing, in particular to a fully automatic docking device for battery pack testing of new energy vehicles. Background technique [0002] With the continuous development of technology, new energy vehicles have begun to be put into use on the market. A new energy vehicle is a car that uses a single battery pack as the energy storage power source. It uses the battery pack as the energy storage power source, provides electrical energy to the motor through the battery pack, drives the motor to run, and then drives the car to travel. [0003] As the energy storage power source of new energy vehicles, battery packs must be tested with a test system before being put into use. In the battery pack test system, a docking plug is needed to connect the battery pack to the test system for battery charge and discharge test, battery safety test, battery parameter test, BMS test, auxiliary function test and other functional test...
