Abstract
The invention discloses a current protection type battery pack which comprises a battery pack body formed by a plurality of rows and a plurality of lines of cells, wherein metal sheets are arranged on the upper surface and the lower surface of the battery pack body, each metal sheet comprises a main connecting section and contact points respectively arranged at two sides of the main connecting section at an interval in a staggering manner, and self-fusing sections are connected between the main connecting section and the contact points; the contact points are positioned just above anodes of cells. The width of the self-fusing sections is smaller than that of the main connecting section. The metal sheets are nickel sheets or copper sheets or copper alloy sheets. The current protection type battery pack is simple in structure, reasonable in design, and convenient to operate; after the metal sheets are provided, when self currents of the cells are overlarge, the cells are disconnected with the main connecting section, so that the cells form an isolated battery, so that the explosion probability of batteries is reduced.
Description
Technical field
The present invention relates to cell art, especially a kind of current protection type battery pack being widely used in electric automobile industry.
Background technology
Along with the development of society, the raising of people's living standard, automobile is also more and more universal.But meanwhile, the problem of global environmental pollution and oil shortage is also more outstanding.People start the power source considering to use battery as automobile, and the electric automobile of this use new green power arises at the historic moment.The design of battery pack needs to consider several factors, should ensure that battery performance meets automotive needs, also will ensure that battery has enough fail safes, reliability, also need consider battery pack and coordinate to reduce complete vehicle quality and volume between automobile, these are all closely related with the structure of battery pack.In traditional battery for electric automobile group, when one of them cell causes self electric current excessive because of fault, very easily on fire, if without fire prevention measure, periphery cell is then easily caused also to catch fire, fire spreading even causes the blast of whole battery pack, and traditional battery for electric automobile group fire protecting performance is poor, there is potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, the current protection type battery pack that explosion-proof performance is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of current protection type battery pack, comprise the battery pack formed by the cell arranging multiple row more, upper and lower two surfaces of described battery pack are equipped with sheet metal, described sheet metal comprises main linkage section and interval and to be staggered point contact being listed in main linkage section both sides, is connected with from molten section between described main linkage section and contact; Described contact is positioned at directly over cell positive pole.
Further, the described width from molten section is less than the width of main linkage section.
Further, the described width from molten section is 2 ~ 3mm.
Further, described sheet metal (3) is nickel sheet or copper sheet or alcu alloy film.
When one of them cell of battery pack causes self electric current excessive because of fault, temperature raises, cell positive pole contacts with contact, temperature is delivered to from molten section by contact, automatically fuse from molten section, cell and main linkage section are disconnected, and form isolated battery, other cells still can normally use.Arranging sheet metal can avoid battery pack on fire, reduces the blast probability of battery, does not affect the normal use of battery pack.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, easy to operate, after sheet metal is set, when cell self electric current is excessive, cell and main linkage section are disconnected, make cell form isolated battery, reduce the blast probability of battery.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of sheet metal in Fig. 1.
Wherein: 1. battery pack, 2. cell, 3. sheet metal, 31. main linkage sections, 32. contacts, 33. from molten section.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of current protection type battery pack as depicted in figs. 1 and 2, comprise the battery pack 1 formed by the cell 2 arranging multiple row more, upper and lower two surfaces of described battery pack 1 are equipped with sheet metal 3, described sheet metal 3 comprises main linkage section 31 and interval and to be staggered point contact 32 being listed in main linkage section 31 both sides, is connected with from molten section 33 between described main linkage section 31 and contact 32; Described contact 32 is positioned at directly over cell 2 positive pole.Sheet metal 3 is nickel sheet or copper sheet or alcu alloy film.
Further, the width of main linkage section 31 is less than from the width of molten section 33; Be 2 ~ 3mm from the width of molten section 33.
When one of them cell of battery pack causes self electric current excessive because of fault, temperature raises, cell positive pole contacts with contact, temperature is delivered to from molten section by contact, automatically fuse from molten section, cell and main linkage section 31 are disconnected, and form isolated battery, other cells still can normally use.Arranging sheet metal 3 can avoid battery pack on fire, reduces the blast probability of battery, does not affect the normal use of battery pack.
Structure of the present invention is simple, reasonable in design, easy to operate, after arranging sheet metal, cell and main linkage section is disconnected, makes cell form isolated battery, reduce the blast probability of battery when cell self electric current is excessive.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
