Abstract
A battery data retrieving method includes: obtaining multiple timestamps corresponding to a data synchronization platform through a data retrieval system based on a timing correction message and a
response of the timing correction message transmitted between the data retrieval system and the data synchronization platform; calculating transmission delay and sending delay corresponding to the data synchronization platform based on the multiple timestamps through the data retrieval system; calculating
retrieval delay corresponding to the data synchronization platform based on the transmission delay, the sending delay, maximum transmission delay, and maximum sending delay, and transmitting the transmission delay and the retrieval delay to the data synchronization platform; correcting a local system time ofthe data
synchronization platform based on the transmission delay through the data synchronization platform; calculating a data retrieval time based on the local system time and the retrieval delay through the data synchronization platform; and retrieving the battery data based on the data retrieval time through the data synchronization platform, and regularly uploading the battery data to the data retrieval system.
