The storage battery is usually installed in a battery cabinet or a battery rack in a backup power system, and the backup power system is provided with a large number of batteries and has limited space, and is generally installed in multiple layers. During the production process of the storage battery, the case is damaged and liquid leakage is easy to occur due to the fact that the storage battery is not excessively closed or is improperly transported and installed. Once the leakage of the storage battery runs for a long time, the storage battery can corrode a battery cabinet and a battery frame to cause rusting, if the electrolyte of the storage battery flows to the surface of a lower battery, the short circuit can be caused, a fire disaster is caused, and huge economic loss is caused.
For the problem of leakage of the storage battery, the current mainstream method in the industry is to place a tray at the bottom of the storage battery, so that the electrolyte flows into the tray and does not corrode a battery cabinet and a battery frame temporarily. However, the hidden danger caused by leakage of the storage battery cannot be thoroughly solved by the scheme, if the leakage amount of the storage battery is large, the hidden danger can be caused if the electrolyte flows out beyond the capacity of the tray, and the leakage of the storage battery cannot be timely found by a manager if the tray scheme is adopted. In case of leakage of the storage battery, the hidden dangers such as corrosion to a battery cabinet and a battery frame, fire caused by short circuit and the like exist, and the whole battery set can be scrapped after long-time operation.
In conclusion, no matter what kind of leakage prevention measures are adopted, the problem cannot be solved completely when the leakage occurs in the storage battery, and the failure of treatment after long-time operation may cause greater hidden danger and economic loss. Once the leakage of the storage battery is found, the leakage battery is stopped or replaced in time by a more reliable treatment method, so how to find the leakage of the storage battery in time and alarm and inform a manager is a problem which needs to be solved urgently at present.
