DISTRIBUTED ENERGY STORAGE CONTROL SYSTEM
First Claim
1. A Distributed Energy Storage Control System (DESCS) comprises multiple BMS battery units. Several BMS battery units are series connected to form the basic series battery unit and several series battery unit are then parallel connected to form a series-parallel battery system. The DESCS system is formed by several series-parallel battery systems.Each DESCS system is comprised of a DESCS main controller, a set of DESCS transmission interface, several series-parallel controllers, several series-parallel transmission interfaces, and several series battery units. Each battery in the series battery unit is provided with discharge bypass path to ensure the fully use of the energy stored in the battery and to prevent the danger of over heat or explosion of battery caused by reverse charge during the discharge process.The BMS battery unit is comprised of a smart battery unit, a charge bypass circuit, a discharge bypass circuit, a charge bypass path control switch, a charge bypass load resistor, a discharge bypass path control switch, and a super capacitor. The BMS battery unit is provided with a mechanism of discharge bypass path management for a single battery. The super capacitor ensures an uninterrupted power output of the battery during the period of the discharge bypass path activating.The smart battery unit is comprised of a controller (20), a battery cell, and a sensor switch device (charge path control switch and discharge path control switch).The controller is comprised of a microcontroller unit, a series-parallel transmission interface, an isolated transmission interface, a wireless transmission interface, a display unit, a data access unit, a synchronization unit, and a real time clock. The BMS battery unit communicates with and controlled by the upper layer controller via the series-parallel transmission interface. The communication and controlling between BMS battery units are accomplished by the isolated transmission interface. The wireless transmission interface can in place of all wirings in the DESCS system and can bring about a more concise system structure and provide an easy way for maintenance.

Abstract
A Distributed Energy Storage Control System (DESCS) comprised of one or a plurality of identical BMS (Battery Management System) battery unit (40), series-parallel system controller (60) and DESCS main controller (70). Each BMS battery unit (40) including a smart battery unit (10), a discharge bypass path control switch (43), a super capacitor (45), a charge bypass load (46) and charge bypass path control switch (44). This DESCS system substantially promotes the energy efficiency of battery, provides a large scale and complicated energy storage system with on-line repair or replacement of batteries, proceeds charge/discharge task uninterrupted during maintenance, and possesses high maintainability.
