Abstract
The utility model discloses a variably-connected battery box which comprises a battery box shell body, a plurality of monomer batteries arranged in the battery box shell body, and an upper battery box cover. A plurality of conductive connecting sheets are arranged on the inner surface of the upper battery box cover, raised elastic lock pins with opposite positions are respectively arranged at the two ends of the connecting sheets, poles with opposite positions are respectively arranged at the two ends on the upper surfaces of the monomer batteries, each pole adopts a hollow structure, and a hollow space can be matched with each raised elastic lock pin. The elastic lock pins on the connecting sheets are corresponding to the poles on the monomer batteries one by one. The arraying method of the connecting sheets is as follows: when the battery box shell body is covered by the upper battery box cover, the poles of each battery are buckled with the elastic lock pins at the corresponding position of the upper battery box cover, and all the monomer batteries in the battery box shell body are connected in series. The equalizing charge of a battery pack is realized through the assembling/disassembling of the upper battery box cover and the simple as well as convenient changing of the battery connecting methods, thereby increasing the charging efficiency of the battery pack and prolonging the service life of the batteries.
Description
Technical field
The utility model relates to the battery case technical field, relates in particular to a kind of battery case of variable connection.
Background technology
Serious day by day along with environmental pollution, low-carbon economy is especially noticeable.In order to alleviate the pollution of traffic to environment, world major country all begins to widely popularize electric automobile.Battery case also can provide battery management system and charging inlet usually as the significant components that battery is fixed in the electric automobile.Yet the battery in the current battery case connects the fixing series connection form that is, and also can only be whole Battery pack serial connection charge when charging.Because all cells in the whole Battery pack can not be accomplished complete equilibrium, so the part battery can occur when whole group is charged is full of, and the situation that all the other batteries still need charge can influence the charge efficiency of battery pack like this, also can exert an influence to battery life.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is: how to solve battery and when normal the use, need be connected into battery pack, and the problem that can carry out respectively at cell in the needs charging or when measuring battery parameter.
(2) technical scheme
For achieving the above object, the utility model provides a kind of battery case of variable connection, comprise battery case housing 1 and the some cells 2 that place in the described battery case housing 1, described battery case also comprises a battery case loam cake 4, the inner surface of battery case loam cake 4 is provided with some conductive connecting pieces 7, the two ends of described conductive connecting piece 7 respectively are provided with the relative convex flexible lock pin 6 in a position, the two ends of the upper surface of cell 2 respectively are provided with the relative pole in a position 9 and 12, this pole 9 and 12 is a hollow structure, and hollow space can match with the flexible lock pin 6 of convex, flexible lock pin 6 is corresponding with pole 9 and 12 homogeneous one on the cell on the conductive connecting piece 7, and the arrangement mode of conductive connecting piece 7 is: when described battery case loam cake 4 covers on the described battery case housing 1, the pole 9 of each cell 2 and 12 and described battery case loam cake 4 on the flexible lock pin 6 of correspondence position fasten, and make all cells 2 in the battery case housing 1 realize connecting or other any type of electrical connections (being preferably series connection) by conductive connecting piece 7.
Wherein, described battery case housing 1 is provided with charging inlet 3, and described cell 2 links to each other with described charging inlet 3 by lead 5.
Wherein, battery case loam cake 4 is an insulator.
(3) beneficial effect
The technical solution of the utility model is by arranging conductive connecting piece and lock pin in the battery case loam cake, can realize convenience, effectively battery is cascaded, further by using lead that battery is linked to each other with charging inlet, by installation and removal battery case loam cake, can change the type of attachment of battery simply and easily, thereby can realize equalizing charge, and then improve the charge efficiency of battery pack, and prolong the useful life of battery battery pack in the battery case; Simultaneously, by using flexible lock pin, can mount and dismount the battery case loam cake easily.
Description of drawings
Fig. 1 is the battery case overall structure schematic diagram of the utility model embodiment;
Fig. 2 is the battery case loam cake of the utility model embodiment and the structural representation of conductive connecting piece and flexible lock pin;
Fig. 3 is the cell structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Connection is completely fixed the utility model at the battery in the battery case in the prior art, when charging, can only be the shortcoming of whole group series-connected cell charging, a kind of novel battery case is provided, can make battery case be in series connection in use, when needs charge to battery, can charge respectively to cell by charging inlet; When battery management system need be measured battery parameter, also can directly measure each cell by charging inlet.Can improve charge efficiency like this, be convenient to measure battery parameter, also certain help be arranged useful life prolonging battery.
When normally using, need be connected into battery pack in order to solve battery, and need be at the problem of cell when charging or battery management system measurement battery parameter.As shown in Figure 1, battery case according to the utility model embodiment comprises battery case housing 1, a plurality of cells 2 are installed in the battery case housing 1, and battery case housing 1 includes charging inlet 3, and the both positive and negative polarity of cell 2 is connected to charging inlet 3 places by two leads 5.
Shown in Fig. 2～3, battery case loam cake 4 is an insulating material, be fixed with conductive connecting piece 7 on it, two flexible lock pins 6 are coupled together, can also be fixing by pad 8 assistant spring lock pins 6, when battery case loam cake 4 inserts battery case housing 1, flexible lock pin 6 will insert hollow space 10,11 places of the pole 9,12 of each cell 2, thereby by flexible lock pin 6 and conductive connecting piece 7 a plurality of cells 2 in the battery case housing 1 are coupled together, so just make whole battery group form series connection.Under the squeezing action of flexible lock pin 6, battery case housing 1 can form an integral body with battery case loam cake 4.
When electric motor car normally used, battery case loam cake 4 was connected as a single entity with battery case housing 1, make whole battery group keep series connection, and the both positive and negative polarity 9 of cell 2 and 12 can be connected to battery management system by charging inlet 3, measures the parameters such as voltage of battery pack; In the time need or measuring the parameter of cell 2 to cell 2 chargings, can directly battery case loam cake 4 be extracted, this moment, battery case housing 1 each interior cell 2 only linked to each other with charging inlet 3, each cell 2 is no longer connected, and therefore can by charging inlet 3 each cell 2 be charged easily or detect.
