Description

Modular electric storage battery

(1) technical field:

The present invention relates to the battery technology field, be specially a kind of modular electric storage battery.

(2) background technology:

After existing lead acid accumulator repeated charge a period of time, pole plate can occur puncturing in various degree or surperficial lead sulfate crystallization accumulation, causes pole plate part area to lose efficacy, and can't participate in electrochemical reaction, and the efficient of storage battery is descended greatly, has to scrap.The storage battery that for example is used for electric motor car, major part are valve-control sealed lead acid batteries, and it is simple in structure, non-maintaining for this storage battery, extensive use.But mainly because of its cycle charging life-span of damage of pole plate only one year about, the replacing that reduces storage battery just can reduce the cost of electric motor car working service.

Often only appear on the small part pad-face when damage of accumulator plate begins, can will speed up the inefficacy of this battery other parts pole plate because of the damage of its part, and other battery efficiency that the damage of certain battery also can influence in the batteries reduces, and accelerate fatigue, lost efficacy, finally can't use, have to change all storage batterys of whole batteries.If jumbo storage battery can be changed into the storage battery serial connection of a plurality of low capacities, in time change the little storage battery of certain damage, and other unspoiled little storage battery still can continue normal use, can prolong the useful life of storage battery relatively.

But present storage battery, capacity is bigger, interconnects inconvenience, connect improperly also to cause short circuit easily or open circuit, and the batteries of a plurality of series connection on equipment installation and change all inconvenience, be difficult to be used in combination.

(3) summary of the invention:

The modular electric storage battery that the object of the present invention is to provide a kind of a plurality of identical sub-storage battery combination to be in series can conveniently obtain different voltages, and replacing for convenience detach.

For achieving the above object, the modular electric storage battery of the present invention design comprises 2～10 identical sub-storage batterys of series connection, and each sub-storage battery has electrolyte and positive/negative plate are arranged in seal casinghousing, the housing.In symmetrical position, the relative both sides of each sub-accumulator housing the just interconnected end and the negative interconnected end of drawing from positive/negative plate arranged respectively, two sub-battery jar body side surfaces recline mutually, and the positive and negative interconnected end of the two is coupled to each other.

Described sub-accumulator housing is divided into the mutually affixed upper shell and the lower house of sealing, and electrolyte and positive/negative plate are in lower house, and upper shell has on the side of interconnected end and 2～4 fixing holes that traverse upper shell arranged, the center line of fixing hole and this lateral vertical; Two or more sub-battery jar body side surfaces recline successively mutually, the fixing hole of each sub-storage battery of screw bolt passes, and fixedly connected each sub-storage battery is an one.

On the upper shell two lateral walls of described sub-storage battery boss or groove are arranged respectively, above-mentioned positive and negative interconnected end lays respectively on the boss or in the groove, boss matches with groove shapes, and the height that boss protrudes wall is identical with the degree of depth that groove is lower than wall, two sub-battery jar body side surface phases are also leaned on, the boss of a sub-battery jar body sidewall embeds in the groove of another sub-battery jar body sidewall, the positive and negative interconnected end of two sub-storage batterys is coupled to each other, and the sidewall other parts that two sub-accumulator housings are adjacent are pasted mutually.

The just interconnected end of described sub-storage battery is positioned at the boss end face of storage battery upper shell sidewall or the bottom surface of groove, and negative interconnected end is positioned at the bottom surface or the boss end face of the groove of another sidewall of housing.

Described storage battery upper shell have positive and negative interconnected end sidewall around male half coupling or recessed seam are arranged, the difference in height of concave, convex seam and its wall, protrude the height of this wall with boss or the degree of depth that groove is lower than wall identical; Two sub-battery jar body side surface phases are also leaned on the mutual cutting ferrule of the seam of the two housing sidewall.The male half coupling of sub-battery jar body sidewall is identical with the recessed seam width of another sidewall.Sub-storage battery lower house is that transparent material is made.

The advantage of modular electric storage battery of the present invention is: 1, the design's sub-battery cell case structure can make a plurality of sub-storage batterys interconnected extremely easily, as long as a sub-storage battery had the one side of boss and the reeded one side of another sub-storage battery and be close together, the positive and negative interconnected end of the two just interconnects, and does not need to connect with lead again; Former single storage battery is divided into a plurality of sub-storage batterys serial connections, when a sub-battery damage wherein, as long as in time change the sub-storage battery that damages, other just can continue normal use; 2, the book accumulator housing has seam, can install and use on equipment as the storage battery of an integral body behind the mutual cutting ferrule during a plurality of combination; 3, the fixing hole of book storage battery upper shell can firmly fix into an integral body with the batteries after the combination, is convenient to install; 4, book battery jar body sidewall is that transparent material is made, and can know and see whether electrolyte loses in each sub-storage battery, observes pole plate at any time and whether damages, so that in time change.
