Motor electronic control durability test

In the production line test and factory test of the motor and controller for new energy electric vehicles, it is necessary to conduct reliability and durability tests on the product (motor or controller). Generally, it is necessary to use two controllers and two motors to build a towing test bench to verify the reliability and other performance of the product and save a lot of energy consumption.

  • 1、Common DC bus energy feedback scheme
    DC source selection: EVWS series battery simulator and EVWB series bidirectional DC power supply are optional.
    Expand

    Program features:

    1. When braking or decelerating, the energy fed back by the motor can be fed back to the grid without a discharge device.
    2. High cost performance, suitable for the towing stand with the same voltage level of the motor/controller under test and the accompanying test.


     

     

  • 2、Common DC bus energy consumption scheme
    DC source selection: EVWP series DC power supply is optional.
    Expand

    Program features:

    1. When braking or decelerating, the instantaneous energy fed back by the motor can be consumed through the release device
    2. The cost is the lowest, and it is suitable for the towing stand with the same voltage level of the motor/controller under test and the accompanying test.



     

     

  • 3、Dual-channel DC power supply energy feedback scheme I
    DC source selection: EVWBT series bidirectional dual output DC power supply is optional (battery simulator function is optional).
    Expand

    Program features:

    1. When braking or decelerating, the energy fed back by the motor can be fed back to the power grid without a discharge device.
    2. The two outputs can be independently adjusted (24V-800V) and do not affect each other. It is especially suitable for towing benches with different voltage levels of the product under test and the equipment under test.


     

     

  • 4、Dual-channel DC power supply energy feedback scheme II
    DC source selection: EVWBL series bidirectional DC power supply is optional (battery simulator function is optional).
    Expand

    Program features:

    1. When braking or decelerating, the energy fed back by the motor can be fed back to the power grid without the need for a discharge device.
    2. The DC source bus leads out one DC output, which saves equipment cost, and is suitable for the towing platform with a fixed voltage level of the accompanying test motor/controller.
