Abstract
The utility model discloses a 300Ah lithium ion power battery module which comprises a box body, wherein, a plurality of battery packs are arranged in the box body, and each battery pack consists of a plurality of batteries; the positive poles of the batteries of each battery pack are electrically connected with a positive pole confluence plate, and the negative poles are electrically connected to a negative pole confluence plate; a positive pole current collector and a negative pole current collector are respectively arranged on two opposite side edges of the box body; and the positive pole confluence plates are electrically connected to the positive pole current collector through respective fuse devices, and the negative pole confluence plates are electrically connected to the negative pole current collector through the respective fuse devices. The lithium ion power battery module provided by the utility model improves the power battery safety performance, and accordingly, improves the safety performance of buses/automobiles; and when some battery in the lithium ion battery module is short-circuited, the fuse devices automatically turn off so as to protect the safety of other batteries in the whole battery module.
Description
Technical field
The utility model relates to the lithium-ion-power cell field, is specially a kind of 300Ah lithium ion power battery module.
Background technology
At electric bus, electric automobile, battery-operated motor cycle, electri forklift, on the electric bicycles etc., lithium ionic cell module is the core equipment, the security performance quality of battery directly has influence on the security performance with battery apparatus such as electric bus, electric automobile.The battery module of electrokinetic cell has a variety of on the market now; But all be simple connection in series-parallel between n the battery, do not have safeties between the battery, during this battery module comes into operation; In case battery short circuit in the module, all batteries all can be burnt in the module.The battery module of band safeties is still blank in the market.
The utility model content
The utility model purpose provides a kind of 300Ah lithium ion power battery module, the problem that can cause all batteries to burn with the battery short circuit of battery module that solves prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of 300Ah lithium ion power battery module; Include casing; Walk abreast in the said casing and be provided with a plurality of battery pack, each battery pack is made up of a plurality of battery parallel connections, it is characterized in that: in each battery pack; A plurality of anodes are connected electrically in respectively on the anodal cylinder manifold, and a plurality of GNDs are connected electrically in respectively on the negative pole cylinder manifold; Limit, said casing two opposite sides also is respectively arranged with the positive and negative electrode collector; The anodal cylinder manifold of a plurality of battery pack is connected electrically in plus plate current-collecting body through safeties respectively separately, and the negative pole cylinder manifold of a plurality of battery pack is connected electrically in negative current collector through safeties respectively separately.
Described a kind of 300Ah lithium ion power battery module is characterized in that: said safeties are PTC, or the tin fuse, or nickel strap, or aluminium strip, or bimetallic, or memory metal species fuse.
In the utility model, each battery anode is welded as a whole by anodal cylinder manifold, and each anodal cylinder manifold is electrically connected through safeties with plus plate current-collecting body respectively, and plus plate current-collecting body leads to overall positive pole.Each negative pole cylinder manifold is electrically connected through safeties with negative current collector respectively, and negative current collector leads to overall negative pole.
The utility model operation principle is: the electric current of lithium ion battery is flow on the anodal cylinder manifold by positive pole; Through safeties and then flow to plus plate current-collecting body, to overall anodal, through electrical appliance to overall negative pole, negative current collector; Flow to the negative pole cylinder manifold again through safeties, accomplish a loop.Two safeties can be Fuse Type, tubular type fuse, welded type, fuse such as flat, also can be special shape nickel strap or aluminium strip.
The utility model has improved the security performance of electrokinetic cell; Thereby improved the security performance of electric bus/automobile; When in the lithium ionic cell module during some battery short circuits, safeties can automatic disconnection, thereby has protected the safety of other battery in the entire cell module.
Description of drawings
Fig. 1 is the utility model modular structure front view.
Fig. 2 overlooks-the safeties enlarged drawing for the utility model module end face.
Embodiment
Like Fig. 1, shown in Figure 2.A kind of 300Ah lithium ion power battery module; Include casing 1; Walk abreast in the casing 1 and be provided with a plurality of battery pack, each battery pack is made up of a plurality of battery parallel connections, in each battery pack; A plurality of anodes are connected electrically in respectively on the anodal cylinder manifold 2, and a plurality of GNDs are connected electrically in respectively on the negative pole cylinder manifold 3; Limit, casing 1 two opposite sides also is respectively arranged with positive and negative electrode collector 4,5; The anodal cylinder manifold 2 of a plurality of battery pack is connected electrically on the plus plate current-collecting body 4 through safeties 6 respectively separately, and the negative pole of a plurality of battery pack 3 plates that conflux are connected electrically on the negative current collector 5 through safeties 7 respectively separately.
Safeties 6,7 are PTC, or the tin fuse, or nickel strap, or aluminium strip, or bimetallic, or memory metal species fuse.
