Method for controlling storage battery shared manager

Abstract

The invention discloses a method for controlling a storage battery shared manager, which comprises the following steps: accessing all batteries into a system, and acquiring related data in real time by using a DSP of the storage battery shared manager; using a double-loop control strategy for direct-current output; dividing the system discharge current to calculate the average discharge current ofeach group of batteries of the system, performing average value operation on the discharge current of each group of batteries, and performing subtraction on the average discharge current of each group of batteries and the discharge current of each group of batteries to calculate a current difference value; multiplying the mean value of the current difference values by a proportionality coefficient and then superposed on a voltage loop. The DSP in the control system is used for detecting the charging and discharging current, the battery voltage, the system output voltage and the system charging and discharging current of each group of batteries, the working modes are divided into four modes, namely the standing mode, the charging mode, the discharging mode and the protection mode, the stable operation of the system is ensured, and the problem of system battery circulation can be avoided.

Description

technical field [0001] The invention relates to the technical field of a battery sharing manager of a communication base station, in particular to a control method for a battery sharing manager. Background technique [0002] With the economic development of society and economy, mobile communication base stations play an extremely important role in my country's information transmission and people's daily life. The battery is the key equipment to ensure the uninterrupted power supply of communication equipment. The construction cost of the traditional base station battery is the construction cost of the switching power supply. 3 times, so it is of great significance to strengthen the management of the battery, improve its use, and effectively prolong the service life of the battery. [0003] In the actual configuration of the battery, considering the demand for later load expansion, the battery capacity configuration is often too high. Although this solves the problem of batter...
