Abstract
The utility model discloses a lithium ion battery module, which comprises a box. A plurality of battery packs are arranged in the box, each battery pack is composed of a plurality of batteries connected in parallel, a plurality of positive poles and negative poles in each battery pack are connected integrally respectively through a positive collector copper board and a negative collector copper board, each positive collector copper board is respectively electrically connected with a collector copper bar, and each negative collector copper board is electrically connected with the other collector copper bar through a safety device. Safety of the power battery is improved, so that safety of an electric bus/car is improved. When one battery of the lithium ion battery module is short-circuited, the safety device is disconnected automatically, and thereby safety of the whole battery module and other batteries is protected.
Description
Technical field
The utility model relates to field of batteries, is specially a kind of lithium ionic cell module.
Background technology
On electric bus, automobile, lithium ionic cell module is the core equipment, and the security performance quality of battery directly has influence on the security performance of electric bus/vehicle complete vehicle.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 purpose of this utility model provides a kind of lithium ionic cell module, to solve problem that battery short circuit can cause entire cell to be burnt in the lithium ion battery.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of lithium ionic cell module, include casing, walk abreast in the described casing and be provided with a plurality of battery pack, each battery pack is made of a plurality of battery parallel connections, it is characterized in that: a plurality of anodes connect as one by the positive pole copper coin that confluxes in each battery pack, and a plurality of battery cathode connect as one by the negative pole copper coin that confluxes in each battery pack; Be positioned at limit, described casing two opposite sides and also be provided with the collector copper bar, the positive pole of a plurality of battery pack copper coin that confluxes is electrically connected with one of them collector copper bar respectively, and the negative pole of a plurality of battery pack copper coin that confluxes is electrically connected with another collector copper bar by fuse unit respectively separately.
Described a kind of lithium ionic cell module is characterized in that: described positive and negative electrode confluxes and has a plurality of louvres on the copper coin.
Described a kind of lithium ionic cell module is characterized in that: described 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 the positive pole copper coin that confluxes, and each positive pole copper coin that confluxes is electrically connected with one of them collector copper bar respectively, and this collector copper bar is drawn overall positive pole.Each battery pack negative pole is welded as a whole by the negative pole copper coin that confluxes, and each negative pole copper coin that confluxes is electrically connected by safeties respectively with between another collector copper bar, and this collector copper bar is drawn negative pole.
The utility model operation principle is: the electric current of lithium ion battery flows to positive pole by positive pole and confluxes on the copper coin, and then flow to anodal corresponding collector copper bar, to anodal lead division, by the collector copper bar of electrical appliance to negative pole lead division, negative pole correspondence, flow to the negative pole copper coin that confluxes again by safeties, finish a loop.Its safeties can be Fuse Type, tubular type fuse, welded type, fuse such as flat, also can be special shape nickel strap or aluminium strip, on positive and negative electrode confluxes copper coin, have louvre, be convenient to the battery heat radiation.
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.
