Smart battery module system

The invention discloses a smart battery module system which comprises a plurality of battery modules. Each battery module comprises a plurality of battery cells. Each battery module comprises a sampling unit, a communication unit and a control management unit, wherein the sampling unit is connected with the plurality of battery cells and used for collecting battery status information of the battery module, the communication unit is respectively connected with the sampling unit and the control management unit, and the control management unit is respectively connected with a balancing unit, a heat management unit and a fault control unit and used for respectively controlling the working conditions of the balancing unit, the heat management unit and the fault control unit. The disclosed smart battery module system not only can achieve accurate sampling of independent battery conditions such as the voltage, the current and the temperature of the battery modules, but also can carry out independent balancing management, fault isolation, heat management and the like and achieve intelligent management of batteries, and meanwhile can provides data support and guidance for use, maintenance, replacement, and second-time use modes of the battery modules.
