Embodiment Construction

[0052] Such asfigure 1 As shown, the present invention collects the high voltage of the electric vehicle through ADC conversion. The three points of high voltage include the chassis, the positive pole of the battery and the negative pole of the battery. The ADC data is transmitted to the MCU through digital signal optical isolation.

[0053] Such as figure 2 As shown, the ADC1 and 2 high-voltage acquisition methods are connected to the positive pole of the electric vehicle battery, the chassis and the negative pole of the battery through the external interface (red, blue, and black three wires). The voltage between the positive pole and the chassis is V2, the voltage between the negative pole and the chassis is V1, and the voltage between the positive and negative poles is Vb. After the high voltage is divided by electronic R1 and R2, it is AD converted and transmitted to the MCU through the optocoupler. ADC3 is the high-voltage detection output by the system itself. When th...

Abstract

The invention discloses an insulation tester for testing electrical performance of a new energy automobile. The insulation tester comprises a high-voltage acquisition unit, an electric energy acquisition unit, a temperature acquisition unit, a trigger unit and a high-voltage generation unit. The high-voltage acquisition unit comprises two sampling branches, and each sampling branch comprises a first branch and a second branch which are connected in parallel. The electric energy acquisition unit comprises a third branch and a fourth branch which are connected in parallel. The temperature acquisition unit comprises a temperature sensing chip. The trigger unit comprises a 485-communication triggering module and a switch triggering module. According to the insulation tester for testing electrical performance of the new energy automobile in the invention, the full-automatic electric performance test of the electric vehicle in the collision process is realized, not only reliable data is acquired for testing, but also the time is saved for testers in the intelligent testing process, and the operation is convenient.

Description

technical field [0001] The present invention relates to a test instrument, more specifically, relates to an insulation tester used for testing the electrical properties of new energy vehicles. Background technique [0002] New energy vehicles, especially electric vehicles, are becoming more and more popular. Correspondingly, there are a series of safety requirements for electric vehicles after a collision, and the National Standardization Management Committee issued the standard in 2015. The standard stipulates the special safety requirements and test methods for pure electric vehicles and hybrid vehicles with B-level voltage circuits after frontal and side collisions. [0003] At present, there is still a lack of corresponding equipment for this test requirement in China. The test requirements are revised according to the American standard FMVSS305 and the European standard ECE, and the content is basically similar. In summary, the electric vehicle has the following test...
