Description
Technical field
The present invention relates to support equipment of power supply more particularly to a kind of parallel extended systems of high pressure lithium battery energy storage battery cabinet.
Background technology
Ups power, i.e. uninterruptible power supply are that accumulator is connected with host, pass through the modular circuits such as host inverter
Direct current is converted into the system equipment of alternating current.Current ups power supplies field, and 90% is up to using plumbic acid solution ratio
More than, however in recent years, the fast development of lithium battery technology, advantage also gradually highlights, compared with traditional lead acid batteries, lithium battery
The advantages such as, discharge-rate high, small with energy density be big, light weight, long lifespan, use temperature range are wide, lithium electricity UPS solutions
Certainly scheme has become the new selection of client.
Compared to lead-acid accumulator, lithium battery energy density is high, internal resistance is small, has to consider circulation when multigroup used in parallel
Problem.Existing, UPS battery group is frequently with multigroup parallel arrangement：1, ups power preparation time is required in target device longer
The case where when, it is larger to battery capacity demand, it is used in parallel frequently with multigroup battery pack；2, it is that raising UPS stand-by power supplies can
By property, N+1 battery pack schemes are commonly used.
When battery pack is used in parallel, pressure difference just has circulation phenomenon between having group.In the application of UPS backup power supplies, owner is annual
Can periodically electric discharge maintenance test be done to every road battery pack, if direct parallel connection takes back UPS after test, the huge pressure difference gesture between battery pack
Serious circulation phenomenon must be generated, battery pack is damaged, the service life is influenced.
Invention content
In view of the above-mentioned state of the art, technical problem to be solved by the present invention lies in provide a kind of solution UPS electricity
The circulation problem generated when the more battery pack parallel connections in source, to protect the high pressure lithium battery of battery health, the effect that prolongs the service life
The parallel extended system of energy storage cabinet.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of high pressure lithium battery energy storage battery cabinet is parallel extended
System, including UPS hosts and the multiple battery packs for being parallel to the UPS hosts, were equipped between the battery pack and UPS hosts
Fill protective device, the protective device that overcharges includes DC/DC modules, high-voltage diode, high voltage connector and disconnecting switch, described
UPS hosts are separately connected the input terminal and output end of DC/DC modules with battery pack, and the high-voltage diode and DC/DC modules are simultaneously
Connection, the high voltage connector are series at the input terminal of DC/DC modules, the disconnecting switch be set to DC/DC modules and UPS hosts it
Between.
Compared with prior art, the beneficial effects of the invention are as follows：This programme uses between battery anode and UPS hosts
Tandem high pressure diode realizes charging and puts a loop area every solving the problems, such as UPS charge and discharge with mouth；UPS hosts pass through high-voltage connecting
Tentaculum and DC/DC modules charge to battery pack, and DC/DC modules can limit charging current, high voltage connector be disconnected when filling full, both
It plays and overcharges protective effect, and can avoid circulation phenomenon between battery pack.The present invention designs, and is suitble to large-scale promotion.
Description of the drawings
Fig. 1 is the circuit connecting relation figure of the present invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, is the preferred embodiment in the embodiment of the present invention, rather than complete
The embodiment in portion.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of parallel extended system of high pressure lithium battery energy storage battery cabinet, including UPS hosts and it is parallel to the UPS
Multiple battery packs of host are equipped between the battery pack and UPS hosts and overcharge protective device, and the protective device that overcharges includes
DC/DC modules, high-voltage diode, high voltage connector and disconnecting switch, the UPS hosts are separately connected DC/DC moulds with battery pack
The input terminal and output end of block, the high-voltage diode and DC/DC wired in parallel, the high voltage connector are series at DC/DC moulds
The input terminal of block, the disconnecting switch are set between DC/DC modules and UPS hosts.
Multiple battery packs, battery pack 1 to battery pack n are parallel-connected to UPS by disconnecting switch QS.
Battery pack passes through high-voltage diode（D1-Dn）Electric discharge, and separated with charge circuit.
UPS passes through high voltage connector（K1-Kn））It charges to battery pack with DC/DC modules, DC/DC modules, which can limit, fills
Electric current disconnects contactless contactor K, had not only played and overcharged protective effect when filling full, but also can avoid circulation phenomenon between battery pack.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
