Problems solved by technology
In the existing technology, many existing manufacturers have high-temperature aging boxes, which are also very popular in the market, but the functions are relatively simple
There are few special high-temperature aging test devices for pure electric vehicle controllers. There is no load and switch to test whether the vehicle controller can work normally, and it cannot simulate the functional requirements of driving.

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] like figure 1 Shown is the outline drawing of the load box. The indicator light 1 corresponding to the intermediate relay is placed on the front panel to observe whether the vehicle controller is working normally or whether the relay is damaged and needs to be replaced. The interior of the load box is divided into two layers, such as figure 2 and 3 As shown, considering the layout and heat dissipation, the relay 5 is placed on the lower layer, and the enamel resistor 4 with large heat generation is placed on the upper layer.
[0025] figure 2 It is a schematic diagram of the upper layer of the load box of the high-temperature aging box of the vehicle controller, which is composed of 10 enamel resistors 4, 2 terminal blocks 3 and 2 switching power supplies 2. Enamel resistors are mainly for simulating motor work, and heat...

The invention relates to a vehicle control unit high temperature aging test device applied to a pure electric vehicle. The device comprises a high and low temperature alternating test box, a control wiring harness and a load cabinet. The high and low temperature alternating test box and the load cabinet are connected by the control wiring harness. The load cabinet and vehicle control unit control wiring harness in the vehicle control unit high temperature aging test box are both self-control, the interface function of the vehicle control unit is matched to the greatest extent, most complete pins are verified and the universality of the vehicle control unit high temperature aging test box is ensured. In other words, the vehicle control unit after high temperature aging can be applied to any project with different demands.
Description
technical field [0001] The invention relates to a high-temperature aging test device, in particular to a high-temperature aging test device applied to a pure electric vehicle controller. Background technique [0002] Pure electric vehicles have entered the stage of industrialization in my country, and the government supports them very strongly. The pure electric vehicle vehicle controller is the core component of the pure electric vehicle vehicle control system, which plays a very critical role in the normal driving of the vehicle, braking energy recovery, network management, fault diagnosis and treatment, and vehicle status monitoring. The vehicle controller is placed in the body, the motor heating or the external environment temperature will make the vehicle controller work in a high temperature environment, the purpose of the vehicle controller high temperature aging box is to simulate the temperature during use, and detect the Whether it can work normally in the tempera...
