Description
Technical field
The present invention relates to support equipment of power supply more particularly to a kind of lithium battery module maintenance devices.
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.
When lithium ion battery uses in groups, many module connection in series-parallel can be used, wherein one or several in the block when mould
Battery core voltage will safeguard module when higher or relatively low, current maintaining method be the battery core high to voltage into
Row electric discharge, the battery core low to voltage charge.It is to carry out independent charge and discharge both for wherein problematic battery core in maintenance.
Using existing maintaining method, there are the charging effect of each channel battery is inconsistent, cause single battery inconsistent.Battery pack occurs
It is inconsistent that the utilization ratio of battery will be caused to decline.And with the increase of usage time and cycle-index, battery capacity decline and
The difference of ageing process can also aggravate the performance difference of stack battery performance and single battery.In addition, since charging process can not
Control, reliability are poor.
Invention content
In view of the above-mentioned state of the art, technical problem to be solved by the present invention lies in provide it is a kind of use and fill simultaneously
Put control technology, it is ensured that the lithium battery module maintenance device of single battery consistency.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of lithium battery module maintenance device, including
Lithium battery group and charge-discharge control system are connected with charging module, the monomer on each single battery of the lithium battery group
Anode, cathode and the charging module of battery are connected with charge-discharge control system.
Further, the charging module includes AC/DC charging modules, the ac input end of the AC/DC charging modules
It is electrically connected with city, the DC output end of the AC/DC charging modules is connected with the single battery, the anode of the single battery
Charged in parallel switchs and discharge switch, and the charge switch and discharge switch distinguish series diode, the charge switch connection
The DC output end of AC/DC charging modules, the cathode of the discharge switch connection single battery.
Further, resistance is equipped between the discharge switch and the cathode of single battery.
Compared with prior art, the beneficial effects of the invention are as follows：Using charge-discharge control system to each single battery
And fill and put, it is ensured that the charging effect of each channel battery consistency, and the monitoring of each cell voltage and the record of data entirely fill
Electric process is controllable, is adjusted convenient for personnel.It is improved using the equalizaing charge module of independent complete function using modularized design
Product reliability.The present invention designs, and is suitble to large-scale promotion.
