Problems solved by technology

However, despite the above-mentioned maintenance work, there are still problems that the open-circuit faulty battery cannot be found in time, and when an individual battery is open-circuited, the battery pack cannot continue to provide working current for the load in time, which greatly reduces the operating time of the system. stability and reliability

specific Embodiment

[0031] The DC power supply systems in power plants, substations and communication fields all use battery packs running in series as backup power. When the AC loses voltage or the charging equipment fails, the battery packs are discharged to continuously provide working power for the load.

[0032] Taking the conventional 220kV substation DC system as an example, two sets of 220V DC power supply systems are generally used, and the battery pack is composed of 104 2V, 300AH single batteries connected in series. The DC load of the whole station is evenly distributed to 2 sets of DC systems, and the normal load of each DC system is 10A. The accident discharge current is 5-6 times the normal load current, and the accident discharge current is 60A.

[0033] The nominal voltage of the battery in the DC system is 2V, and the maximum voltage is generally not higher than 3V, that is, the maximum reverse voltage of the freewheeling diode is less than 3V, and the reverse withstand voltage o...

Abstract

The invention discloses a storage battery pack structure capable of supplying a discharge circuit for open-circuit batteries and an implementation method thereof. The structure comprises a storage battery pack, wherein a plurality of battery cells are contained in the storage battery pack; the battery cells are connected in series; and each battery cell in the battery cells is connected with a fly-wheel diode for supplying a discharge current passage for the discharge circuit in parallel. The storage battery pack can be used for uninterruptedly supplying a working current for a load by using the storage battery pack structure, so that the accidents such as protective action resistance caused by open-circuit faults of storage batteries can be effectively avoided, and the discharge capacity of the storage battery pack and the power supply reliability of the storage battery pack are greatly improved. The storage battery pack structure capable of supplying a discharge circuit for open-circuit batteries and the implementation method thereof disclosed by the invention can be widely applied in the field of storage battery charging.

Description

technical field [0001] The invention relates to the technical field of battery management and fault detection, in particular to a structure of a battery pack capable of providing a discharge circuit for an open-circuit battery and an implementation method thereof. Background technique [0002] For DC power systems such as electric power and communications, energy storage substations, and electric vehicles, the battery packs are all operated in series. When any of the batteries has an open-circuit fault, the battery will not be able to provide working current, causing the entire battery pack to lose its application. Some effect. In recent years, due to the above-mentioned battery open-circuit fault in the DC system for electric power, the protection and control equipment often refuses to operate, causing large-scale power outages many times, and seriously threatening the safe and stable operation of the power system. [0003] At present, the operation, maintenance and manage...
