Description
Technical field
The utility model relates to a kind of storage battery communication means, particularly-and 48V direct current single system duplicate supply storage battery communication means.
Background technology
Be used for providing power process to communication equipment at traditional double power-supply system, the power supply capacity that occurs the two-way power supply through regular meeting is inconsistent, causes existing between the two-way power supply bigger pressure reduction.Thereby making wherein, discharge appears in that higher road battery of electric power of fan-out capability.For example under the alternating current normal condition, the fan-out capability of power supply A or power supply B is less than the load on this road, perhaps wherein one road power supply input sky is opened escape, and this moment, this road battery of electric power will be in discharge condition, caused the two-way battery of electric power to discharge and recharge unbalanced phenomena; Also may be under the AC outage situation, this moment, the two-way battery of electric power all be in discharge condition, because the load of two-way power supply there are differences, the road battery of electric power discharging current that load is big is big, and cell voltage is low.In addition, though the load unanimity of two-way power supply, if but the power supply capacity of storage battery there are differences, also will cause the battery tension phenomenon lower than another road battery tension of power supply capacity deficiency.Above phenomenon also can cause descend the useful life of storage battery simultaneously not only for causing duration storage battery and power supply to reduce.
The utility model content
The purpose of this utility model is to provide a kind of storage battery output stable for the deficiency that solves above-mentioned technology, no potential safety hazard, and the reliability height is controlled easily-48V direct current single system duplicate supply storage battery communication means.
In order to achieve the above object, the utility model is designed-48V direct current single system duplicate supply storage battery communication means, it comprises storage battery, two-way power supply and monitoring unit, described storage battery is divided into first batteries and second batteries, described first batteries is connected with second batteries by the battery bus connection switch, the battery bus connection switch comprises that switching sky opens, and opens at the switching sky and is provided with electricity behaviour, and electricity behaviour be connected with monitoring unit.The characteristics of this structure are to utilize monitoring unit to monitor the system mode that obtains, and control the relation between the two group storage battery groups in real time automatically, make two group storage battery groups remain at optimum state.
The utility model is designed-changing method of 48V direct current single system duplicate supply storage battery communication means is: when Alternating Current Power Supply normal, first batteries or the second batteries module fan-out capability are less than this road load current, at this moment, this road battery of electric power is in discharge condition, electric power output voltage descends, when voltage difference is greater than 0.7V between two batteries, monitoring unit control electricity behaviour makes battery bus connection switch closure, first batteries and second batteries output contact output, that higher road power supply of output voltage participates in another lower road power supply of output voltage for carrying, and realizes the storage battery balanced discharge; When exchanging power failure, first batteries and second batteries begin discharge, if the load that this moment, the two-way power supply connect there are differences or two-way battery of electric power power supply capacity is inconsistent, to cause two-way electric power output voltage fall difference, when if the output voltage difference is greater than 0.7V between the two Battery pack groups, monitoring unit control electricity behaviour makes battery bus connection switch closure, the higher power supply of output voltage participates in the lower power supply of output voltage for the work of carrying, and makes the output voltage of first batteries and second batteries near consistent; When the storage battery communication means is in closure state, if satisfy following three conditions simultaneously: 1. first batteries exchanges input normally with second batteries, 2. the power module load capacity is enough, module does not have the current limliting alarm, and 3. the storage battery of first batteries and second batteries all is not in discharge condition; Monitoring unit sends storage battery communication means ON-and OFF-command, and first batteries and the second battery cell bus connection switch disconnect.This control method mainly by monitoring unit control, according to different situations, is controlled the connection situation between the two group storage battery groups, makes two group storage battery groups remain at optimum state.
In order to adapt to some special environments for use, the battery bus connection switch is set to manual state in the described control unit, monitoring unit will be controlled the break-make of storage battery communication means no longer automatically, and directly by manually controlling the annexation between the two group storage battery groups.
The utility model is resulting-48V direct current single system duplicate supply storage battery communication means, and in traditional double loop power supply output system, when solving double loop power supply fan-out capability difference well, the loaded work piece that road of power supply fan-out capability deficiency connects is unusual.Correlation by the storage battery communication means, the power supply that fan-out capability is abundant participates in that not enough road power supply of fan-out capability and provides electric power to load, thereby realized the mutual compensation of fan-out capability between the double loop power supply well, guaranteed that effectively two-way load that power supply connects can both steady operation, also solved when supplying power with double circuit, the two-way power supply is got in touch with the problem of output mutually.
Secondly in the single system duplicate supply, by the storage battery communication means two-way out-put supply is carried out association output, if the storage battery of one road power supply begins discharge, monitoring unit detects this road output voltage and another road electric power output voltage difference when surpassing 0.7V, monitoring unit control communication means is connected, high-tension circuit in time participates in the circuit of low-voltage for carrying, make that batteries stops or reducing discharging current in the circuit of low-voltage, reduced the imbalance problem that discharges between the storage battery of two-way power supply effectively, prolong simultaneously the useful life of storage battery effectively, had favorable economic benefit.
