The invention provides a device and method for realizing a communication cascade of multiple lithium battery groups. The device comprises a host machine, an upper machine and more than one slave machines. The host machine is electrically connected with each of the salve machines respectively. The host machine is also electrically connected with the upper machine. The host machine and each of the slave machines comprise a battery group which is provided with a protective plate, and an isolation communication circuit which is electrically connected with the battery group having the protective plate. Therefore, a use state of each battery group can be effectively monitored so that a situation of an overcharge or an over-discharge of each battery group can be avoided, and a use safety of the whole battery group system is enhanced.
Description
technical field [0001] The invention belongs to the technical field of circuit control, and in particular relates to a device and method for realizing communication cascading of multiple lithium battery packs. Background technique [0002] In the existing battery application design, it often involves connecting multiple battery packs in series or in parallel to obtain a battery system, thereby increasing a higher battery voltage or a higher capacity to the outside world. However, due to the problems of technology and materials, there will be certain differences in the internal characteristics of each battery pack, and as the number of charge and discharge of the battery pack increases, this difference between each battery pack will gradually increase, which will lead to the The usage status of the group is different. [0003] Therefore, during the use of each battery pack, how to effectively monitor the use status of each battery pack, so as to avoid the occurrence of overc...
