Introduction to the EDR data box on the Tesla car

The EDR data box on the Tesla is produced by Bosch. It has an independent system and has nothing to do with the Tesla system. Even if the Tesla system is ruined, this is a faithful record, and this data cannot be modified. And the special data providing tool costs 1,200 US dollars a piece. A nationally recognized testing agency in Shanghai has this tool.

It is the picture below. The Shanghai testing agency and the police asked the family members to test and analyze the EDR data of the vehicle under the witness of three parties. The family members did not agree and did not attend, but the police still conducted analysis and testing together with the Shanghai testing agency. The results are identical to the data provided by Tesla.
