Detection apparatus for charging power distribution module

Technical Field

The utility model relates to a new forms of energy technical field that charges specifically is a detection device of power distribution module charges.

Background

The development speed of new energy automobiles is witnessed in recent years, the new energy automobiles become one of the industries of China and the leading world at present, and nine new energy automobiles are electric automobiles needing to be charged, so that the charging facility becomes an important infrastructure for the development of the new energy automobiles, and meanwhile, the charging facility also becomes the biggest short board for restricting the rapid propulsion of the new energy automobiles. In the last two years, the relative hysteresis of infrastructure support such as charging piles has become increasingly prominent. Although the number of charging piles is increasing rapidly, what is not negligible is that the growing scale of new energy vehicles is still greatly higher than that of charging piles, which means that gaps between the charging piles are still expanding.

The reliability of the power distribution module unit serving as a core component of the high-power charging pile is particularly important, when a charging gun is inserted into a vehicle charging port, the main control of the charging pile is communicated with a vehicle-end battery management system, the vehicle end provides voltage and current required by the vehicle and transmits the voltage and the current to the charging pile, the charging pile distributes proper power to the vehicle end according to the requirement of the vehicle, the power distribution module unit is responsible for the task. For example: a360 KW fills electric pile has been equipped with ten rifle that charge, just also means can serve ten cars simultaneously. If a bus comes to charge, after the vehicle pile communication process is completed, the voltage 580V and the current 250A are required by the vehicle, and at the moment, the charging pile can allocate appropriate power to the vehicle end according to the vehicle demand by the power distribution module. The output power of the charging pile can be 145KW by voltage and current, and the charging pile with 360KW also has 215KW in a dormant state to prepare for remaining nine charging guns. It can thus be seen that the power distribution module provides suitable power to charge the vehicle on the one hand. On the one hand, the loss of the charging pile is reduced, and the utilization rate of a power grid is greatly increased.

The power distribution module unit has a large effect in the charging pile, so that the stability of the power distribution module unit directly influences the quality of the charging pile, and corresponding functionality and reliability tests of the component need to be emphasized. As shown in fig. 2, if the power distribution module 1 has ten inputs, during the test, it is necessary to connect the ten ports to the dc power supply 2 by using wires, and forty ports, one positive port and one negative port, need to insert twenty wires into the ports end to end. A360 KW's of a ten rifle fill electric pile need pack into ten power distribution modules, test a power distribution module then just need plug pencil eight hundred times. On one hand, the skin is broken by the hand of the detector after being plugged and pulled back and forth by hand. On the one hand, the duration of the entire test is extended (about ten minutes is required to test a module patch cord). On the other hand, the shutdown waiting of the next installation procedure is influenced, and meanwhile, the fatigue wear of the end reed is easily caused by back-and-forth plugging, so that the reliability of the product is reduced. In addition, the long-term plugging and unplugging can cause abrasion of the test wire harness, so that certain waste is caused. There is a need for a testing apparatus that saves time and is easy to operate without affecting the premature fatigue aging of the corresponding components of the product as a result of testing.
