Internal resistance be greater than default internal resistance in the case where, determine that the internal resistance of corresponding cell batteries is abnormal, that is, exceed standard requirements；To internal resistance
First detection module 101 on abnormal cell batteries sends the instruction of internal resistance activation repairing.
Correspondingly, first detection module 101 can be also used for after receiving the instruction of internal resistance activation repairing, in battery group
It in the case where floating charge state, proceeds as follows: taking DC current from the positive and negative anodes of corresponding cell batteries, and by direct current
Electric current is converted to pulse ac electric current；Pulse current is supplied to the positive and negative anodes of corresponding cell batteries, to corresponding monomer electric power storage
The internal resistance in pond carries out activation repairing, until the internal resistance of cell batteries meets preset standard requirement.Pulse ac electric current can swash
The sediment of the sulfide crystallization and sulfuric acid that are generated on cell batteries internal electrode plate living due to long-term floating charge, so that the list
Accumulator body internal resistance reaches standard requirements, extends the service life of cell batteries.
In above-mentioned implementation, on the one hand, determine that the mode of internal resistance is simple and accurate；On the other hand, in cell batteries
In the case where there is internal resistance exception, corresponding cell batteries can be carried out with online internal resistance activation repairing in time, to ensure monomer
The normal operation of battery realizes effective maintenance to battery group.
As another implementation, analysis and processing module 103 is in the voltage and battery according to each cell batteries
After the total current of group determines the internal resistances of each cell batteries, can be also used for: cell batteries internal resistance less than the first threshold
In the case where value, determine that short trouble occurs for corresponding cell batteries；It is greater than the feelings of second threshold in the internal resistance of cell batteries
Under condition, determine that open-circuit fault occurs for corresponding cell batteries；Occur in the corresponding cell batteries of determination short-circuit or open-circuit fault
In the case of, it is alerted.In practical applications, first threshold can be set to the value of very little, such as close possible to 0 Ω；And
Second threshold can be set to very big value, such as approach infinity.

Analysis and processing module 103 can indicate control module to secondary power supply equipment send the second control instruction, with to battery group into
Row charging, such as fill or floating charge.Alternatively, analysis and processing module 103 can also adjust secondary power supply equipment with prompting maintenance personnel
To be filled to battery group or floating charge.
It, can be by the long-range control of application in movable maintenance terminal to battery charging when alternating current normal power supply
The float charge voltage of secondary power supply equipment, with to battery group proof discharge capacity or full capacity detect.For example, can be with
The float charge voltage of secondary power supply equipment is lowered to 47V or 46V etc. by normal value (such as 53.5V or 54V), to detect battery
Proof discharge capacity.In another example the float charge voltage of secondary power supply equipment can be lowered to 45V etc. by normal value, with inspection
Survey the full capacity of battery.
When mains failure, battery group automatic discharging.Analysis and processing module 103 can calculate electric power storage according to the following formula
The discharge capacity of pond group or cell batteries: discharge capacity=I (discharge current) × H (electric discharge duration), the unit of discharge capacity
For ampere-hour (AH).Analysis and processing module 103 can also according to the following formula calculating accumulator group or cell batteries electric discharge hold
Amount: discharge capacity=I (discharge current) × H (electric discharge duration) × U (total voltage of battery group or the voltage of cell batteries),
The unit of discharge capacity is that ampere-hour lies prostrate (AHV).
The various information that data summarization platform can be sent according to analysis and processing module 103 or the data collector where it
Generate the numbers such as total voltage, discharge current, discharge capacity, electric discharge duration, socking out capacity, the socking out duration of battery group
