Technical Field
The utility model belongs to the technical field of energy storage system and specifically relates to an uninterrupted power supply energy storage module system.
Background
The device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery for short. Batteries are commonly used in the field of energy storage. Because the voltage grade of each battery is low, the batteries need to be connected in series and parallel to form an energy storage module, and then the energy storage modules are connected in series to form a battery cluster, and the battery cluster is connected into the PCS converter to be charged and discharged in an external grid-connected mode. If a certain energy storage module breaks down, the battery cluster cannot discharge outwards, so that other normal energy storage modules cannot work even when being placed, and resources are wasted.

The utility model aims at solving the not enough and provide an uninterrupted power supply energy storage module system of above-mentioned technique, also can guarantee the normal work of battery cluster when certain one or more energy storage module trouble in the battery cluster.
In order to achieve the above object, the utility model discloses an uninterrupted power supply energy storage module system, including two at least energy storage modules and BMS battery management system, it forms the battery cluster to establish ties between the energy storage module, the battery cluster inserts the external charge-discharge that is incorporated into the power networks of PCS converter, every energy storage module all includes the group battery and two output terminal that link to each other with the positive negative pole of group battery respectively, be provided with first switch module between the output terminal with the anodal of group battery and correspondence or with the negative pole of group battery and the output terminal that corresponds, be provided with the second switch module between two output terminal of same energy storage module, first switch module and second switch module all are controlled by BMS battery management system, and first switch module and second switch module remain the exclusive control throughout. The energy storage module can select two series connection, three series connection, five series connection, ten series connection or even more series connection according to actual conditions.
Above-mentioned technical scheme, insert the PCS converter and externally cut in the incorporated into the power networks and charge and discharge after establishing ties between the energy storage module, when normal operating condition, first switch module is normally closed state, and the second switch module is normally open state, and the energy storage module can normally be exported this moment. When a certain energy storage module fails, the BMS battery management system controls the first switch module and the second switch module in the energy storage module to act, namely the first switch module is regulated to be in a normally open state, the second switch module is regulated to be in a normally closed state, the energy storage module is bypassed at the moment, and the positive electrode and the negative electrode of the battery pack are in open circuit, so that the normal operation of the whole system is not influenced, the energy storage module is disconnected between the positive electrode and the negative electrode, and safe maintenance, replacement and the like can be carried out.
The first switch module and the second switch module are any one of MOSFET, IGBT and relay. The MOSFET is a switch circuit module which takes the MOSFET as a main component and has the functions of conduction and disconnection; the IGBT is a switching circuit module which takes the IGBT as a main component and has the functions of conduction and disconnection; the relay is a switch circuit module which is formed by taking the relay as a main component and has the functions of connection and disconnection.
