Description
Technical field
The present invention relates to field of power supplies, relate in particular to a kind of communication power supply and use the battery intelligent cut-in method
Background technology
Existing backup power system is if increase the back charging time; Must increase the backup battery capacity, promptly storage battery of parallel connection arrives system again, when the direct parallel connection of the battery that has voltage difference is used; When especially pressure reduction was very big, the phenomenon of the high battery of voltage to the anti-filling electricity of low battery can appear; Again because of battery discharge current much larger than charging current, so this anti-filling electricity is easy to the overcurrent that charges, the battery that is recharged can receive bigger infringement.
Summary of the invention
The present invention provides a kind of and with the adjustment automatically of realization power-supply system a kind of communication power supply of the final parallelly connected connecting system of battery pack of two different voltages is used the battery intelligent cut-in method.
Technical scheme provided by the invention is following:
A kind of communication power supply system uses the battery intelligent cut-in method, and described system has access to first Battery pack, when inserting second Battery pack,
Step 1 detects the magnitude of voltage of second Battery pack and compares with various magnitudes of voltage in the described original system;
Step 2 imposes the mode that inserts or refuse access according to the result who relatively draws in the step 1 to described second Battery pack.
Further, also comprise the step of judging that said system works is whether stable before the step 1, then carry out step 1 if said system works is stablized.
Further; Various voltages in the described original system comprise: system's ceiling voltage, float charge voltage, busbar voltage; Step 2 further comprises the steps: A, if the second Battery pack magnitude of voltage is higher than system's maximum voltage value, thinks that then this Battery pack specification refusal that do not match inserts; B if but the second Battery pack magnitude of voltage is lower than system's ceiling voltage is higher than system's float charge voltage, then improves system busbar voltage gradually, during less than a particular value A, inserts second Battery pack up to the difference of busbar voltage and the described second Battery pack voltage; C, if the second Battery pack voltage is lower than system's float charge voltage, then refusal inserts.
Further, said particular value A is 0.2V.
Further, if when the described second Battery pack voltage is lower than system's float charge voltage, the mode that refusal inserts is: second Battery pack is as the offline standby battery.
Further; This method further comprises: during the civil power outage; The difference that first Battery pack discharges into or both voltages identical with described offline standby cell voltage is during less than particular value B; Insert described second Battery pack, two Battery packs discharge until described busbar voltage less than battery protection voltage simultaneously then, two Battery pack detachment systems.
Further; This method further comprises: during the civil power incoming call; Check at first whether second Battery pack is installed, if installed then first Battery pack and second Battery pack are charged simultaneously, if second Battery pack is not installed then only first Battery pack charged.
Further, described particular value B is 0.2V.
Further; Various voltages in the described original system also comprise: the first Battery pack voltage; This method further comprises: whether the voltage of voltage and described second Battery pack of relatively judging described first Battery pack is greater than a certain particular value C; If then carry out steps A or step B or step C, if not then inserting described second Battery pack.
Further, described particular value C is 0.2V.
Beneficial effect of the present invention: avoided the anti-phenomenon of irritating of charging that voltage difference produces between the battery fully, battery pack need not to carry out artificial pressure regulation and inserts original bus simply fast.Perfect each battery cell of detection can report battery operated state and fault message immediately through communication bus comprehensively.Rational battery charging and discharging administrative mechanism has prolonged battery useful life.

Embodiment
Referring to accompanying drawing 1; A kind of communication power supply is used the battery intelligent cut-in method, and it has access to first Battery pack, when under the situation of original system steady operation, inserting second Battery pack; Step 1 detects the magnitude of voltage of second Battery pack and compares with various magnitudes of voltage in the described original system; Step 2 imposes the mode that inserts or refuse access according to the result who relatively draws in the step 1 to described second Battery pack.
Various voltages in the described original system comprise: system's ceiling voltage, float charge voltage, busbar voltage, the first Battery pack voltage, step 2 further comprises the steps:
A if the second Battery pack magnitude of voltage is higher than system's maximum voltage value, thinks that then this Battery pack specification refusal that do not match inserts;
B if but the second Battery pack magnitude of voltage is lower than system's ceiling voltage is higher than system's float charge voltage, then improves system busbar voltage gradually, when the difference of busbar voltage and the described second Battery pack voltage is zero or 0.2V, inserts second Battery pack;
C, if the second Battery pack voltage is lower than system's float charge voltage, then refusal inserts second Battery pack as the offline standby battery.
Simultaneously according to the voltage of the voltage of relatively judging described first Battery pack and described second Battery pack whether greater than 0.2V, if then carry out steps A or step B or step C, if not then inserting described second Battery pack.
In civil power when outage,, the difference that first Battery pack discharges into or both voltages identical with described offline standby cell voltage inserts described second Battery pack during less than 0.2V; Two Battery packs discharge until described busbar voltage less than battery protection voltage simultaneously then; Two Battery pack detachment systems when civil power is sent a telegram here, check at first whether second Battery pack is installed; If installed then to the charging that powers on simultaneously of first Battery pack and second Battery pack, realized two Battery packs fully and connect; If second Battery pack is not installed only to the charging that powers on of first Battery pack.
