Description
Technical field
The present invention relates to set of cells, automatically calibrate learning method and system more particularly, to a kind of set of cells, battery capacity.
Background technology
Battery backup unit (BBU) plays important role in the data cut-off protection function of disk array, when the unexpected power down of system power supply of whole array, in order to prevent the data do not brushed in internal memory into hard disk from not losing, BBU or the set of cells that is made up of several BBU must be used to system power supply, take corresponding method to protect internal storage data, due to this power down can not phase property, therefore have to last for ensureing that set of cells (heavy-current discharge is ferric phosphate lithium cell essentially) is in the state that capacity is higher, to guarantee that system can be powered the data protection of power down by battery when power down occurs suddenly.
Characteristic due to lithium battery; corresponding protection circuit is needed to carry out charge and discharge protecting; for storage system, the parameter such as health status and the capacity that will grasp lithium battery in real time, therefore storage lithium battery group has capacity measurement chip and relevant protection circuit.Lithium battery group is in long-term use procedure, it may appear that unbalanced between each combination battery core, the situations such as capacity measurement deviation is inaccurate.Particularly within the storage system, temperature is general higher, long-time set of cells is in the state close to full punching, these all can be caused battery capacity and measure existing relatively large deviation, it is therefore desirable to regularly (be usually three months to half a year not etc. depending on the battery core situation cycle) and battery carries out volumetric correction study (learning).
The capacity that current industry adopts automatically is calibrated learning style and is substantially two kinds: the first, when capacity calibrates study automatically, adopt battery-powered master control veneer that battery discharges (master control veneer passes through software design patterns power consumption control in certain limit)；The second: with special discharge load on master control borad, when capacity calibrates study automatically, regularly carries out electric discharge calibration study to set of cells.
But, under both modes, storage system is intended to stopping business and automatically calibrates study action to respond battery capacity.Set of cells has the discharge and recharge calibration parameter of self, accomplish once more satisfactory calibration, need discharge current, charging current, and time of repose compares strict restriction after electric discharge, for order first two calibrating mode, the first cannot accomplish the control (the bad control of system single board power consumption) of discharge current completely；The second, can control discharge current preferably, but the set of cells that generally storage system uses is relatively larger, and the electric discharge of numerous battery core collectives can produce relatively larger heat in guiding discharge load.Storing system in two kinds of situations will the service disconnection of long period.If discharge current must be strengthened in order to save the time and shortens the time of repose after discharging, the precision problem of battery calibrating so will certainly be caused.These a little problems are for needing to use the other system of set of cells power supply in support to exist too.
