Description
Technical Field

In addition, the invention also relates to a device for detecting the online running quantity of the battery, which implements the method for detecting the online running quantity of the battery.
Background
In an electric power system, a power plant, a transformer substation and a communication machine room all adopt a direct current system to provide reliable working and power supplies for relay protection devices, control loops, monitoring equipment, communication equipment and the like in the station. The direct current system plays an important role in safe and stable operation of electric power infrastructure, and mainly comprises a charger, a storage battery pack, a battery polling instrument, a direct current bus, a monitor, an ammeter, a voltage transformer, a switching or contact handle, a feeder line unit and the like.
The charger serves as a main power supply source, outputs a certain direct current voltage when in normal operation, and provides a power supply for the total-station direct current load. The output parameters are monitored and controlled by the monitor, and the operator can input fixed value items on the interface of the monitor to control other parameters such as the output voltage and the like. The storage battery pack is used as a standby power supply and is kept connected with the charger and the direct current load during normal operation, when the charger fails, the storage battery supplies the direct current power supply, and the total-station direct current load is guaranteed to keep normal operation within a certain time. Because the storage battery pack is connected with the charger, the charger supplies power to the direct current load and carries out floating charging on the storage battery pack at ordinary times; at intervals, the charger automatically changes the floating charging state into the uniform charging state.
In the prior art, a monitor fixed value item is set by a setting personnel and executed by a maintenance personnel. The checking or the overhaul of the storage battery pack is usually performed by another professional worker, and the following two kinds of misoperation are easy to occur: the actual running battery is not checked, and the battery is directly input into a monitor to be executed according to a fixed value set by the rated battery number; when the quality of individual batteries is degraded and the operation is stopped, the corresponding fixed values of the float charging voltage, the uniform charging voltage and the like are not changed in time. Any one of the above misoperation causes the whole battery pack to be in an overcharged state for a long time, seriously damages the quality and the service life of the battery, and even causes serious accident events such as protection failure and the like.
In summary, how to avoid long-term overcharge of the storage battery is a problem to be solved urgently by those skilled in the art.
