[0002] The current electric vehicles, especially the hydrogen fuel cell electric vehicles, are more and more used in China, especially the newly developed new energy vehicles, the development cycle is short, the product is new, and the verification cycle is short; In the stages of design testing and calibration verification, there are product consistency, poor controllability, and some unpredictable failure risks; most of the current vehicle safety protection is limited to requiring each electronic component to implement its own independent protection; this As far as product design verification is concerned, for new vehicles, each component can only identify and avoid part of the risks; it cannot fully identify the risks of personnel and external facilities from the perspective of the entire vehicle. For this reason, we propose A safety protection device for hydrogen fuel cell electric vehicle calibration test process
