Abstract
The utility model discloses an upper cover for a lithium-ion battery pack of a fixed fuse wire with externally-arranged bolts. The upper cover comprises an over-current protection device; the over-current protection device is a fuse wire; fuse wire mounting bolt holes are formed at the outer side of the upper cover of the lithium-ion battery pack; and a fuse and the upper cover of the lithium-ion battery pack can be fixed through the bolts. According to the upper cover for the lithium-ion battery pack provided by the utility model, the over-current protection device in a protection system is replaced by using the fuse wire in the circuit with large continuous working current, namely the working current more than 10A; the protection system can improve the reliability of the protection device without considering over-current protection design; and furthermore, the fuse wire is externally mounted in a bolt fixing manner, so that the upper cover is convenient to mount and replace.
Description
Technical field
The utility model belongs to lithium ion battery group assembling field, is specifically related to a kind of lithium ion battery group loam cake.
Background technology
It is long that lithium ion battery has the life-span, lightweight, volume is little, convenient mobile, be convenient to transportation, and the production and application process is free from environmental pollution, it is a kind of ideal battery, the application of present domestic lead-acid battery is very wide, and substantially all is the valve-regulated lead-acid battery that uses, and this battery is relatively heavier, life-span is also short, production process is polluted extremely serious, substantially stops at the domestic production lead acid accumulator in developed country, and the product of this heavily contaminated has been put into developing country's foundry, the paces that add the production domesticization of lithium ion battery critical component are accelerated, cost is within sight, and from integrated cost, high efficiency lithium ion battery of long-life than lead acid accumulator more economically.
But because the existence of the high-energy-density of lithium ion battery, organic flammable electrolyte and very active lithium metal; so that lithium ion battery or battery pack are in use; must be equipped with protection system; to prevent battery or battery pack super-charge super-discharge or to surpass the use that designs, to protect its safety in utilization.
That protection system generally has is anti-overcharge, cross put, the basic function of anti-short circuit, anti-overflow.In these four basic functions, anti-overflow (overcurrent protection) function, when design current hour, its heating is less, but when design current is larger, its severity of generating heat has a strong impact on the reliability of protection system.Therefore, for the larger protection system of design current, one of overcurrent protection is a chicken ribs for protection system.
Therefore, need a kind of new design to address the above problem.
The utility model content
The utility model purpose: the utility model provides a kind of lithium ion battery group loam cake with external bolt fastening fuse for the defective of the lithium ion battery pack outer case design of prior art.
Technical scheme: for solving the problems of the technologies described above, the lithium ion battery group loam cake with external bolt fastening fuse of the present utility model adopts following technical scheme:
A kind of lithium ion battery group loam cake with external bolt fastening fuse; comprise protective device; described protective device comprises overcurrent protective device; described overcurrent protective device is fuse; the arranged outside of described lithium ion battery group loam cake has fuse construction bolt hole, the fixing described fuse of bolt and described lithium ion battery group loam cake.
Beneficial effect: the utility model is larger for the continuous firing electric current; be in the circuit of operating current greater than 10A; substitute overcurrent protective device in the protective device with fuse; the protection system device can be considered the overcurrent protection design; improve the reliability of protective device; the installation of fuse has been taked externally in addition, in the fixing mode of bolt, conveniently installs and changes.
Description of drawings
Fig. 1 is of the present utility model not with the stereogram of the lithium ion battery group loam cake of external bolt fastening fuse;

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also illustrated in figures 1 and 2ly, the lithium ion battery group loam cake 1 with external bolt fastening fuse of the present utility model comprises overcurrent protective device 3.Overcurrent protective device 3 is fuse, and the arranged outside of lithium ion battery group loam cake 1 has fuse construction bolt hole 2, and wherein, fuse is bolted on the lithium ion battery group loam cake 1.Substitute overcurrent protection in the protection system with fuse, protection system can be considered the overcurrent protection design, improves the reliability of protection system, and the installation of fuse has been taked externally in addition, in the fixing mode of bolt, conveniently installs and changes.
Wherein, be provided with positive terminal 3, negative terminal 5 and detection hole 4 on the lithium ion battery group loam cake 1.Wherein, can detect by detecting hole 4 the inside situation of lithium ion battery group, convenient maintenance.
Also comprise Insurance Block, fuse is arranged in the Insurance Block, and Insurance Block is arranged on the fuse construction bolt hole 2.By with the Insurance Block dismounting, be convenient for changing fuse.Fuse of the present utility model is power current fuse, and wherein, the operating current of power current fuse is greater than 10A.
Also comprise baffle, baffle is bolted on the lithium ion battery group and covers.Install the threaded post that fixing baffle is used additional in lithium ion battery group loam cake inside, so that baffle thoroughly is fixed on the battery case.The mode that traditional method sticks with glue agent is bonded in baffle on the housing, easily like this comes off and has a strong impact on circuit heat radiation, reduces circuit reliability.
