Embodiment approach

[0060] In the above embodiment, the external addressing device directly interacts with the wireless information collection device of the battery pack to complete the addressing. In this case, if the distance between the two battery packs is relatively close, for example, a battery is installed next to the battery pack 1 in the front part. Packet n may cause the target address after addressing to not correspond to the location of the battery pack, resulting in addressing errors, requiring repeated addressing, which reduces addressing efficiency; or the written address information is illegal, causing the master It is impossible to identify which battery pack collects the information based on the address information. Therefore, another implementation method is proposed: also take the addressing of the battery pack 1 located in the front part of the vehicle as an example:

[0061] Such as Figure 4 As shown, it mainly includes the following steps:

[0062] (1) When addressing the...

Abstract

The invention relates to a battery pack wireless information acquisition device and an addressing method and addressing system thereof, and belongs to the technical field of battery system management. A first wireless radio frequency identification module is arranged in the battery pack wireless information acquisition device; a second radio frequency identification module coupled with the wireless radio frequency identification module is arranged in an external addressing device; after generating target address information, the external addressing device communicates with the first radio frequency identification module through the second radio frequency identification module, and writes the target address information into the battery pack wireless information acquisition device; and the battery pack wireless information acquisition device performs address configuration of a wireless network according to the target address information to complete addressing, so that the problems of low speed and low efficiency of a method for addressing the battery pack information acquisition device in the prior art are solved.

Description

technical field [0001] The invention relates to a battery pack wireless information collection device, an addressing method and an addressing system, and belongs to the technical field of battery system management. Background technique [0002] The battery pack applied to electric vehicles usually includes multiple battery modules or battery boxes connected in series. In each battery module and battery box, a corresponding battery management system is required to manage the battery. The room needs to be connected according to the predetermined wiring harness. [0003] As the degree of electrification of the vehicle increases, the wiring harness of the vehicle becomes more and more complex. The high-voltage wiring harness and the low-voltage wiring harness are intricate. This will not only affect the safety of the system, but also increase the cost of using the wiring harness and reduce production efficiency. Therefore, the research on the wireless battery management system ...
