Processing and storing battery data

A data processing device, comprising:

• one or more processors;
• and
• a non-transitory computer-readable memory coupled to the one or more processors, the memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, from a client device, the battery data via a CAN protocol;
• pushing the battery data into a buffer sequentially, wherein the earliest battery data is popped out from the buffer;
• decoding the popped battery data with a CAN DBC file provided by the client device;
• packing the decoded battery data into a JSON file and transmitting the JSON file to a cloud.

A method for storing battery data in a cloud server, comprising:

• receiving, from a data processing device, a plurality of JSON files, wherein the JSON files are stored in a raw data folder within the cloud server;
• formatting the JSON files in the raw data folder by using a first function, and saving the formatted JSON files in a processed data folder within the cloud server;
• and
• combining the formatted JSON files in the processed data folder by a second function and saving the combined JSON files in a data catalog within the cloud server.
