The invention discloses a BMS (Battery Management System) decentralized detection and centralized management system of modularized lithium batteries. The decentralized detection and centralized management system comprises an upper BMS module and a plurality of lower BMS modules, wherein each of the lower BMS modules corresponds to one lithium battery module, and all the lower BMS modules are connected to the upper BMS module in parallel through a CAN bus port; each of the lower BMS modules is used for detecting the charging and discharging information of the corresponding lithium battery module and sending the detected results to the upper BMS module; the upper BMS module performs centralized management on the charging and the discharging of lithium battery modules through the CAN bus according to the received detection results. According to the decentralized detection and centralized management system disclosed by the invention, the conventional BMS technique is applied to the decentralized and centralized management of the modularized batteries; the lower BMS module in each module uploads the voltage of each battery unit to the BMS through the CAN bus so as to perform unified control and management. Through the adoption of the decentralized detection and centralized management system disclosed by the invention, the PACK, the structure mounting and the maintenance of the lithium batteries can be greatly simplified.
