Abstract
The invention discloses a storage battery BMS protocol management system which is characterized by comprising a two-dimensional code recognizer, a CPU, an AD conversion module, a wireless signal transmitting module, a signal processing module, a power module, a wireless signal receiving module, a bus interface and a terminal controller. The two-dimensional code recognizer provided by the inventioncan read a BMS protocol two-dimensional code of each lithium battery module in the module process of the lithium battery module; the BMS protocol information read by the two-dimensional code recognizer can be subjected to anti-interference processing through the set signal processing module, and the information processed by the signal processing module can be transmitted to the terminal controller through the wireless network through the wireless signal transmitting module, so that a manager can read the BMS protocol of each lithium battery module of the module lithium battery, and unified management of the BMS protocol of each lithium battery module of the module lithium battery is realized.
Description
technical field [0001] The invention relates to a BMS protocol management system, in particular to a storage battery BMS protocol management system. Background technique [0002] As the number of electric vehicles continues to increase, the number of off-line lithium batteries used in electric vehicles is also increasing. Most of these off-line lithium batteries are due to their discharge time and discharge capacity. To recycle the off-line lithium batteries, we will module the lithium battery modules of different lithium batteries, that is, to recycle the old lithium batteries. The BMS protocols of different lithium batteries are also different. When reusing old modules, it is necessary to manage the BMS protocols of each lithium battery module in the lithium battery of the module through the corresponding management system to prevent the lithium battery after the module A certain lithium battery module in the battery is overcharged or overdischarged, which affects the rel...
