Compared with the prior art, the battery pack equalizer disclosed by the utility model has the following advantages: 1) the battery pack equalizer is simple in design and low in manufacturing cost; and 2) before a battery pack is assembled, multiple monomer batteries to be combined can be equalized by using the battery pack equalizer so as to guarantee that the performances of the monomer batteries in the battery pack are consistent.
Description
[technical field]
The utility model relates to the balanced adjusting device that is applied to the lithium ion battery group, is a kind of battery pack balancing device specifically, is used for guaranteeing that the performance of lithium ion battery group each battery when assembling is basically identical.
[background technology]
The lithium ion battery group is widely used in various electric locomotives and the automation equipment as storage and the conversion equipment of energy.When system's required input power is larger, usually some lithium ion battery connection in series-parallel are got up to use, for example the power supply on the electric automobile just is comprised of thousands of lithium ion battery connection in series-parallel.
Lithium ion battery group after the above-mentioned assembling in actual use, namely in the process that discharges and recharges, the whole service life of lithium ion battery group is compared obvious shortening with single lithium ion battery, this mainly be since in the lithium ion battery electrochemical properties of each cell have certain difference.When some cells were filled electricity, other cells also need continue charging, like this with regard to so that problem appears overcharging in the cell that has been full of, overcharge and to produce very adverse influence to lithium ion battery, it is mainly manifested in: battery capacity descends, and internal resistance increases, the lost of life.
In view of this, necessaryly provide a kind of battery pack balancing device to solve the problems of the technologies described above.
[utility model content]
The purpose of this utility model provides a kind of simplicity of design, low cost of manufacture and can guarantee the basically identical battery pack balancing device of performance of lithium ion battery group each battery when assembling.
To achieve these goals, the utility model provides a kind of battery pack balancing device, the insulation support body that it comprises framework and is used for support frame, described framework is comprised of with some mutually non-touching metal support beam two parallel insulators, and the spacing between the described metal support beam can be held cell and guarantee the two ends utmost point and the metal support beam electrical contact of cell.
As a kind of improvement of the utility model battery pack balancing device, the rectangular shape of described framework exterior contour, the two ends of described metal support beam are connected on the insulator and are parallel distribution.
As a kind of improvement of the utility model battery pack balancing device, the two ends utmost point of described cell is respectively screw rod and the nut that is spot welded to the cell two ends.
As a kind of improvement of the utility model battery pack balancing device, also be provided with a control switch between described every two adjacent metal support beam.
As a kind of improvement of the utility model battery pack balancing device, described battery pack balancing device also comprises a voltmeter, and described voltmeter be used for to be measured the be connected in parallel voltage at two ends of battery of battery pack balancing device.
Compared with prior art, the benefit that has of the utility model battery pack balancing utensil is: 1) simplicity of design, low cost of manufacture; 2) before the assembled battery group, can use it to some cells that equilibrium will be made up, consistent with the performance that guarantees each cell in the battery pack.

Fig. 1 is the vertical view of the utility model battery pack balancing device;
Fig. 2 is the front view of the utility model battery pack balancing device;
Fig. 3 is another view of the utility model battery pack balancing device.
[embodiment]
The purpose of this utility model, technical scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.Should be understood that, the embodiment of describing in this specification only is in order to explain the utility model, is not in order to limit the utility model.
Please refer to Fig. 1 to shown in Figure 3, the utility model provides a kind of battery pack balancing device 100, the insulation support body 10 that it comprises framework and is used for support frame, described framework is comprised of with some mutually non-touching metal support beam 30 two parallel insulators 20, and the spacing between the described metal support beam 30 can be held cell 40 and guarantee the two ends utmost point and metal support beam 30 electrical contacts of cell.
In actual applications, can be according to size and the demand attractive in appearance in space, framework is designed to different shapes, such as the exterior contour of the framework in the present embodiment be rectangular-shaped be exactly the shape of one of them, be fixedly attached to the two ends of metal support beam 30 on the insulator 20 again and be parallel distribution.
The utility model battery pack balancing device is mainly used in cylindrical cell, and the two ends utmost point of described cylindrical cell is respectively screw rod 41 and the nut 42 that is spot welded to the cell two ends.
Also be provided with a control switch (not shown) between aforementioned every two adjacent metal support beam 30, described battery pack balancing device 100 also comprises a voltmeter (not shown), and described voltmeter be used for to be measured the be connected in parallel voltage at two ends of battery of battery pack balancing device.
The utility model battery pack balancing device 100 is like this work: the some cells 40 that first needs are assembled into battery pack are placed in and form multirow on the framework, and the two ends utmost point that guarantees each cell is resisted against respectively on the metal support beam 30, like this, some cells 40 with delegation are connected in parallel, subsequently, just can measure with voltmeter the terminal voltage of batteries in parallel connection.Just the time that can estimate required equilibrium according to magnitude of voltage (is exactly in the battery of some parallel connections on the balanced process nature, voltage high to the low process of charging of voltage), after the time that reaches expection, just can cut off the control switch between two adjacent metal support beam 30 of this row.
The utility model battery pack balancing device, be not restricted to described in specification and the execution mode, therefore for the personnel of familiar field, can easily realize additional advantage and modification, therefore in the situation of the spirit and scope that do not deviate from the universal that claim and equivalency range limit, the utility model is not limited to specific details, representational equipment and illustrates here and the examples shown of describing.
