Aging test device for AC charging pile

Abstract

The invention belongs to the technical field of AC charging piles, especially to an aging test device for AC charging piles. The aging test device comprises a tester interface, a current power control unit, an auxiliary power supply, a phase detection unit, a communication unit and a human computer interface. The aging test device further comprises a current equalization unit, a current adjusting unit and an AC current multiplier, wherein the current power control unit controls the current adjusting unit through the current equalization unit to output two paths of current with different magnitudes, the current adjusting unit is connected with the AC current multiplier, the AC current multiplier comprises a live-line current multiplier and a neutral-line current multiplier, and the live-line current multiplier and the neutral-line current multiplier are serially connected to a live line and a neutral line, which connect a test input interface and a test output interface. The aging test device is safe, reliable, convenient, energy saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of AC charging piles, in particular to an AC charging pile testing aging device. Background technique [0002] Existing AC charging piles, AC billing devices, etc. often need to be connected to loads such as bulb heating wires to consume electric energy when testing aging, and are used to measure the current flowing through the equipment. The equipment works at a high current for a long time for a period of time to test the functional performance of the equipment. It is a waste of AC power; if the car charger is used to add a battery, the battery will be more and more full, the current will become smaller and smaller, and it will be discharged when it is full, which will not achieve the purpose of aging for a long time at the set current. Connect the actual useful load to the billing device, but there is no suitable test aging equipment with adjustable current. It is the aging of conventional heating wires,...

[0002] Existing AC charging piles, AC billing devices, etc. often need to be connected to loads such as bulb heating wires to consume electric energy when testing aging, and are used to measure the current flowing through the equipment. The equipment works at a high current for a long time for a period of time to test the functional performance of the equipment. It is a waste of AC power; if the car charger is used to add a battery, the battery will be more and more full, the current will become smaller and smaller, and it will be discharged when it is full, which will not achieve the purpose of aging for a long time at the set current. Connect the actual useful load to the billing device, but there is no suitable test aging equipment with adjustable current

It is the aging of conventional heating wires, which has disadvantages such as inconvenient adjustment of current setting, large volume, heat generation, and fire hazards.

In addition, before the AC charging pile ages, it is necessary to shake hands with the vehicle and communicate with the vehicle. The heating and luminous load does not meet these conditions. It is often necessary to burn the test program or manually close the internal contactor of the AC charging pile. This is very troublesome and cannot guarantee recovery. After leaving the factory, the handshake communication of the machine is normal, but there are hidden dangers
