By setting up the middle computer between the upper computer and the lower computer of the battery monitoring system, and using the middle computer to save and forward a large amount of battery data, a distributed data transmission network is constructed to realize the distributed storage of battery data. Even if the upper computer is abnormal, the lower computer can continue to work, and the data during the abnormal period of the upper computer will be stored through the middle computer, and the battery data will not be lost. It will be forwarded after the upper computer recovers, which improves the monitoring ability of the battery monitoring system. Furthermore, the technical problem of poor monitoring ability of the battery monitoring system in the related art is solved.

As shown in Figure 1 is a schematic diagram of an optional battery monitoring system according to an embodiment of the present application. As shown in Figure 1, the battery monitoring system may include a plurality of lower computers (lower computer A1, lower computer A2, lower computer A3, lower computer B1, lower computer B2, lower computer B3, only show 6 among Fig. 1, can be less or more in reality), at least one middle computer (middle computer A, middle computer B, Fig. Only 2 are shown in 1, which can be less or more in practice) and host computer: the host computer is connected to all intermediate computers (intermediate computer A, intermediate computer B), and each intermediate computer is connected to multiple At least one lower computer in the lower computer (each middle computer in Fig. 1 is connected with 3 lower computers, for example, middle computer A connects lower computer A1, lower computer A2, lower computer A3, middle computer B connects lower computer B1, lower computer B2, and lower computer B3 may be less or more in practice, and the number of lower computers connected to each middle computer may be different).

Optionally, a TCP communication connection is used between the upper computer and the middle computer, and a CAN communication connection is used between the middle computer and the lower computer. The middle computer is connected with the lower computer through CAN communication, so that real-time and reliable data communication can be realized between the lower computer and the middle computer, and the middle computer is connected with the upper computer through TCP communication, so that the middle computer and the upper computer can be Realize data communication with long transmission distance and high transmission rate. By combining two communication methods in the battery monitoring system, the battery monitoring system has the advantages of both CAN communication and TCP communication, and has high real-time performance, reliability, and transmission distance. It is long and has a high transmission rate, which significantly improves the monitoring capability of the battery monitoring system and is conducive to the monitoring of large quantities of batteries.

Optionally, the central computer may mark the battery data sets successfully transmitted to the host computer with the transmission time, and determine the battery data sets in the target storage area that have no transmission time marked as the battery data sets to be sent. When the distance between the transmission time and the current time exceeds the preset duration, the central computer can delete the battery data set corresponding to the transmission time.

Optionally, the central computer can directly delete the battery data set successfully transmitted to the host computer, and the battery data set retained in the target storage area is the battery data set to be sent.

The battery data set to be sent may not only include the target battery data set collected during the abnormality of the upper computer, but also include the battery data set collected by the upper computer before the abnormality occurred, and may also include the battery data set collected by the upper computer after returning to normal.
