Description
Technical field
The invention belongs to batteries discharge storage batteries series and parallel conversion equipment, be widely used in various robots, electric motor car, electric device and the control system etc. of using a plurality of storage batterys, convert parallel connection during charging to, convert series connection during discharge to.
Background technology
Along with robot and electric motor car number of applications, present known machines people, electric motor car, electric device and control system etc., the power of system, control and processing need lean on the group series connection of a plurality of storage batterys to realize its function; All adopt serial connection charge and discharge; Serial connection charge can cause the charging loss big, and the charging interval is long, recycles shortcomings such as number of times reduction; Storage battery uses a period of time because resistance increases the phenomenon of easy heating when charging; Charging socket does not have protective device, charging socket oxidation sparking when moist when patching occurs, even causes problem such as short circuit spontaneous combustion.
The inventor is in the embodiment of the present invention process; Find that there is following problem at least in existing technology: series connection of existing storage battery group or string and the batteries of mixing; The process of charging is the positive charge of charger; Positive pole through storage battery exchanges to negative pole through separator, the positive pole from the negative terminal of the negative pole of storage battery to another group storage battery again, and the first group storage battery negative discharge is to the positive pole of second group storage battery; Exchange to negative pole through the separator device once more, circulation is to the last finally accomplished charging process in last negative pole unit of a group storage battery like this.
In this course; Electric current passes through 2 electron reactions of the electron reaction of first group storage battery to another group storage battery, certainly will produce the in-fighting phenomenon, and the multipotency consumption is big more more for cycle-index; Cause the excess loss of electricity big more, the whole world has consumed a large amount of unnecessary energy for this process every year.
In this course, be charged to the circulation that discharges into charging, because the generation of in-fighting and the time lengthening that the resistance increase causes charging.
Simultaneously in discharge, charging once equals to have influenced the access times of storage battery more than the secondary several storage batterys when charging in this course.
Because the charge in batteries discharge time is inconsistent, when reaching the increase that certain number of times will have a resistance,, resistance produces the heating distortion along with increasing, seriously influence whole electric system.
The present charging socket of another side does not have a protection, and charging socket is also charged when not charging, and receives dirt and short circuit easily in non-charged state, and unavoidable the generation struck sparks and the short circuit spontaneous combustion.
According to this a series of shortcoming, transfer into parallel connection with artificial series connection and solve loaded down with trivial details and easy error.
Summary of the invention
Cause the excess loss of electricity when charging, prolong the charging interval and influence access times, charging socket unprotect for being connected on for plurality of groups of storage batteries; Chargedly receive dirt and short circuit easily in non-charged state, artificial series connection transfers a series of shortcomings such as deficiency of parallel connection trouble and easy error, the device that the present invention provides a kind of storage battery series and parallel to change; This conversion equipment is located on the charging socket, during charging, rotates the charging socket door; Main gear shaft in the interlock, charging socket is opened, and slip wire jumper portable plate; With being connected with charged in parallel end socket on the parallelly connected jumper wire plug insertion parallel connected end socket, connect simultaneously jumper wire plug and connect end socket and the disconnection of discharged in series end socket, the back locator that puts in place is locked; Correctly convert the circuit of series connection to parallel circuits easily, but reach the safety that charged in parallel ensures application system again, let electric current fill simultaneously to plurality of groups of storage batteries; Save electric energy and charging interval, increased access times.
During discharge, rotate moving main gear shaft, the slip wire jumper portable plate gone up of the charging socket couplet on the door; With parallelly connected jumper wire plug and parallel connected end socket and the disconnection of charged in parallel end socket, and cover charging socket, insert connect end socket and discharged in series end socket to the series connection jumper wire plug simultaneously; Locator litter and locator chute are locked after putting in place; Correctly convert the circuit of parallel connection to series circuit easily, keep the cleaning of charging socket, charging socket is broken off fully increases system safety.
The present invention solves technical scheme that its technical problem adopts: correctly conveniently convert the batteries of series connection to charged in parallel; Ground is battery charging when reaching energy-conservation joint, increases storage battery useful life, can break off charging, the closed charging of discharge; The cleaning that keeps charging socket; And and when changeing string charging and discharge socket break off the increase system safety fully, steady position device ensured apparatus of the present invention close the position accurately, and the wire jumper portable plate slide smooth and easy.
A said further device is provided with: the convenient main bodys such as robot, electric motor car, electric device and control system that do not take of the charging socket door operation of said device; When series connection conversion also broken off charge power supply; In non-charged state capping charging socket, ensured charging socket cleaning and safety.
A said further device is provided with: when the charged in parallel state need convert discharged in series to; The moving last jumper wire board gear grooved of going up main gear shaft interlock wire jumper portable plate of the electrical socket couplet on the door of said device; End pinion axle through in the end pinion axle chute slides up and down, and forwards charging socket to and covers, the many rows multidigit series connection jumper wire plug on the wire jumper portable plate; Insert the series connection of many row's multidigit series connection end sockets simultaneously and be communicated with, and charging socket breaks off DC power supply.
A said further device is provided with: when the discharged in series state need convert charged in parallel to; The charging socket door of said device forwards to be opened; Many rows multidigit series connection jumper wire plug on the wire jumper portable plate; The end socket of connecting with many rows multidigit breaks off with discharged in series end socket simultaneously, and the many rows multidigit parallel connection jumper wire plug on the wire jumper portable plate inserts multidigit parallel connected end sockets and the charged in parallel end sockets arranged respectively more simultaneously; Parallel connected end socket and charging socket are connected simultaneously, and the concrete quantity of row's number and figure place is according to the quantity of storage battery.
A said further device is provided with: the locator litter of said device and locator chute, and guiding wire jumper portable plate location slides up and down, and put in place the fore shaft of back locator litter and the spring tapered end of locator chute are locked.
The invention has the beneficial effects as follows: convert DC series to the DC parallel charging; And the disconnection discharged in series, in-fighting and resistance between the solution batteries is interior are eliminated unnecessary in-fighting; Charging needn't repeatedly circulate and save the charging interval; Solution produces unnecessary discharge when charging, increase access times, solves and receives dirt and short circuit easily at discharged in series state charging socket; Ensure charging socket cleaning and safety effectively, also ensured the safety of application systems such as robot, electric motor car, electric device and control system when charging.
