Abstract
The utility model discloses a kind of safeguard construction of battery pack, comprise some Battery packs and be cascaded, described every Battery pack is made up of some batteries in parallel connection branch roads, and at least one fuse that each branch road is connected.Compared with prior art, the benefit that the safeguard construction of the utility model battery pack has is: 1) each batteries in parallel connection branch road is in series with fuse, can realizes the function of horizontal and vertical protection; 2) modularized production, production efficiency is high, and repair and maintenance is convenient.
Description
[technical field]
The utility model relates to power battery pack interconnection technique, particularly relates to a kind of safeguard construction of battery pack.
[background technology]
Automobile day by day becomes the daily general living supplies of people, thing followed energy consumption and pollution problem have become the significant challenge of pendulum in face of world community and each automobile manufacturing company, and the new-energy automobile of exploitation energy-conserving and environment-protective is future automobile industrial expansion directions.In the new-energy automobile competition of all multiple types, pure electric automobile, hybrid electric vehicle is shown one's talent gradually.But as pure electric vehicle, the electrokinetic cell of the requisite critical component of hybrid electric vehicle, but has the life-span on the low side, the feature that cost is high.In order to improve the life-span of battery, a series of problem must be resolved, and such as, ensures battery operated under safe condition, prevents over-charging of battery, crosses and put and avoid excessive electric current to flow through the problems such as battery.
Battery pack has first rear tandem plan in parallel, scheme in parallel after also having first series connection.Adopt the scheme of first and rear string, mutually balanced between cell in parallel, consistency is better, if but there is short trouble in a certain single battery, it will become the load of other batteries in parallel connection with it, the energy of all batteries in parallel with it discharges rapidly in fail battery, thus causes more serious consequence.Employing is the rear also scheme of string first, if certain joint cell breaks down, the energy of other cells can only be discharged by shunt circuit, and is absorbed by other battery in series-connected cell, discharges and stop when voltage is elevated to series connection group rated voltage.
Sign in this, be necessary to provide a kind of safeguard construction of new battery pack to overcome the deficiencies in the prior art in fact.
[utility model content]
The purpose of this utility model is to provide a kind of safeguard construction of battery pack, and this safeguard construction can ensure that battery pack all realizes protection on horizontal and vertical.
To achieve these goals, the utility model provides a kind of safeguard construction of battery pack, comprises some Battery packs and is cascaded, and described every Battery pack is made up of some batteries in parallel connection branch roads, and at least one fuse that each branch road is connected.
One as the safeguard construction of the utility model battery pack is improved, and described each batteries in parallel connection branch road is all in series with the cell of equal number.
Compared with prior art, the benefit that the safeguard construction of the utility model battery pack has is: 1) each batteries in parallel connection branch road is in series with fuse, can realizes the function of horizontal and vertical protection; 2) modularized production, production efficiency is high, and repair and maintenance is convenient.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the safeguard construction of the utility model battery pack.
[embodiment]
In order to make, the purpose of this utility model, technical scheme and Advantageous Effects are more clear to be understood, below in conjunction with the drawings and specific embodiments, is further elaborated to the utility model.Should be understood that, the embodiment described in this specification is only used to explain the utility model, is not to limit the utility model.
Please refer to shown in Fig. 1, a kind of safeguard construction 100 of battery pack, it comprises the two Battery pack groups be cascaded, and described every Battery pack group comprises again some parallel branches, each parallel branch all comprises three cells 10 and a fuse 20 is cascaded.
In actual production process, usually can require that the cell number that parallel branch is connected is consistent, be conducive to the portfolio effect realizing cell like this.
The safeguard construction of the utility model battery pack owing to being provided with fuse unit in each parallel branch; therefore; it can realize the function of horizontal and vertical protection, and the fuse adopted can specifically be determined according to the quantity of cell or change, and facilitates follow-up maintenance.Vertical protection involved by the utility model is: for the parallel branch in arbitrary Battery pack, and when cell is short-circuited fault, excessive electric current passes through this parallel branch, then the fuse that can fuse in this parallel branch; Involved cross-protection is: when certain parallel branch is short-circuited, other parallel branches will be charged to this branch road, but sign in being provided with fuse, therefore can ensure that other branch roads of cut-out are to the charging of this fault branch in time.
The safeguard construction of the utility model battery pack, be not restricted to described in specification and execution mode, therefore additional advantage and amendment can easily be realized for the personnel of familiar field, therefore when not deviating from the spirit and scope of 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 described.
Claims (2)
1. a safeguard construction for battery pack, comprises some Battery packs and is cascaded, it is characterized in that: described every Battery pack is made up of some batteries in parallel connection branch roads, and at least one fuse that each branch road is connected.
2. the safeguard construction of battery pack as claimed in claim 1, is characterized in that: the cell described each batteries in parallel connection branch road being all in series with equal number.
