Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
Embodiment 1:
Fig. 2 shows the preferred embodiment of the method for storage battery redundancy reprovision group of the present invention, the method is applied to performance monitoring processing module, batteries and break-make and selects between module, in batteries, there are a plurality of storage batterys, storage battery comprises work storage battery and redundancy storage battery, the quantity of storage battery of wherein working is a plurality of, the quantity of redundancy storage battery is at least one, storage battery selects module to form one for the series loop to power consumption equipment power supply by break-make, break-make selects module and storage battery to form one-to-one relationship, and method comprises the following steps:
S101: performance monitoring processing module is monitored the performance data of the work storage battery in batteries and redundancy storage battery, performance data comprises one or more in voltage, internal resistance and the capacity of storage battery.
S102: performance monitoring processing module judges that whether the voltage of work storage battery or internal resistance or capacity is abnormal, if so, carries out S103, if not, represents working properlyly, again carries out S101 and monitors.In this step, as long as there have one of them work voltage of storage battery or internal resistance or capacity to occur to be abnormal, just judge that this work storage battery is for abnormal, need to change, here abnormal refer to be this voltage or internal resistance or capacity not in normal scope, concrete scope is that the nominal value or the actual environment that according to storage battery producer, provide are set.In addition, performance data also can comprise the group voltage of batteries, the temperature of batteries, the reference value when group voltage of batteries can be used as the preposition judgement of voltage and manual maintenance batteries, the judgement of voltage, internal resistance and capacity also with the temperature correlation of batteries, at different temperature, value range all can change to some extent, and these Ye Shiyou producers provide, and do not repeat them here.
