Abstract
The present invention relates to a battery pack of an electric vehicle, which comprises a set of batteries and a box body which is used for containing the batteries. The present invention is characterized in that the box body is made of FRP materials. The present invention adopts the special FRP materials and the structure of special FRP materials, electrode posts of the batteries are protected, and the short circuit phenomenon of the electrode posts of the batteries which causes bigger damage when accidents occur can not occur. Because of the non-conducting characteristics and the structure characteristics of the FRP (Fiber Reinforced Plastics) materials, the assembly is simple, concise and safe, battery groups can be closely contacted at any face after the assembly is finished, and the usage space can be greatly saved. Because the FRP materials have stronger anticorrosive characteristics, various kinds of performance can not be affected in adverse environment. Because the density of the FRP materials is much smaller than that of iron, the structure weight of the FRP materials is much lighter than that of the iron, and the structure cost of the FRP materials is lower than that of the iron.
Description
[technical field]
The present invention relates to the battery of electric vehicle bag, relate in particular to the improvement of battery of electric vehicle bag box body.
[background technology]
The batteries of electric automobile bag generally comprises battery pack and holds the box body of battery pack.At the beginning of generation nineteen ninety, the box body of power brick only is some simple box.Because the power brick box body needs enough intensity using and to protect the driver during accident, so its box body generally all makes with stainless steel and other metal materials, and material is the intensity height often, and is easy to make, used widely.
But such safety of structure is relatively poor, and structure self can not insulate, and the pole of battery and high pressure electric installation and various detection sampling apparatus are not had suitable protection, can not alleviate damage and can increase the weight of damaged condition on the contrary when meeting accident.Have acid mist in actual use in the power brick and produce, metal structure can not well be resisted corrosion, thereby reduces the useful life of structure.And the big load that increases car load of architecture quality has shortened mileages of continuation.Because the conductive characteristic of structure is also extremely inconvenient when operation, operating efficiency is lower.Cost is also higher.
Also there is part to use the structure of special material, but all solves the contradiction that improves between fail safe and saving cost, the production convenience.
[summary of the invention]
Purpose of the present invention is exactly can not satisfy the problem that improves fail safe, saves cost, production convenience in the prior art simultaneously in order to solve, and proposes a kind of new battery of electric vehicle bag.
The battery of electric vehicle bag that the present invention addresses the above problem comprises a Battery pack and holds the box body of described battery, described box body is by FRP (Fiber Reinforced Plastics, dimension reinforced plastics glass fibre, or title glass fiber reinforced polyester resin) material is made, two pole protective sleeves are arranged on described box body, be arranged at the positive and negative terminals place of battery, it is characterized in that: the battery unit in the described battery is connected in series or parallel by cell connector; And described box body is provided with brace protection cavity.
Further,
Described battery is provided with the voltage sample line, also is provided with voltage sample wire harness passage on described box body, is convenient to the voltage sample line and draws.
Described battery is provided with temperature sensor, has temperature sensor to compress block on described box body, the protection temperature sensor.
On described box body, also be provided with the wire harness protection passage, the voltage sample line wire harness that protection is drawn from battery.
On described box body, also be provided with the wire harness protection passage, the temperature sampling line wire harness that protection is drawn from battery.
On box body, seal press strip, carry out spacing battery.
Described box body comprises framework, top cover, is fixed with the power brick management box on framework.
Described framework comprises two section plates, four L shaped edge frame bars and four holders compositions in order to fixed connecting piece; Described four edge frame bars and two section plates form box body in order to hold battery, and an end of framework is opened a breach, puts into battery during in order to assembling.
Described top cover comprises fixing hole, has brace protection cavity, voltage sample wire harness passage, temperature sensor to compress block, whole wire harness protection passage and pole protective sleeve holder, is fixed with the pole protective sleeve on the described pole protective sleeve holder.
The present invention adopts special FRP material and structure, and the pole of battery is protected, and the pole of battery can short circuit when meeting accident, and causes bigger damage.Because FRP (Fiber Reinforced Plastics) the non-conductive characteristic of material and the characteristics of this structure make assembling simple, succinctly also safer, battery pack can contact by the tight of arbitrary face with battery pack after assembling was finished, and had saved usage space greatly.Because the FRP material has stronger Anticorrosive Character, under adverse circumstances, use various performances also can not be affected.Because the density of FRP material is little a lot of than iron, makes the quality of structure than the irony structure very big alleviating arranged.Also the cost than the irony structure is low for cost when producing in batches.
In addition, the present invention also is provided with brace and protects cavity, voltage sample wire harness passage, temperature sensor to compress block, wire harness protection passage, seal press strip etc., has improved the assembly technology of structure, has improved efficient, has also saved cost during batch process.Not only well protected pole, preventing under unexpected situation, can not cause more serious consequence, and well fixing and protected voltage sample and temperature sampling wire harness, saved the space that utilizes of battery pack, simplified structure and save cost.

[embodiment]
Characteristics of the present invention are that box body is made with the FRP material.This kind material if structural design is unreasonable, will bring the inconvenience in the making owing to can not adopt technology such as welding as metal material.The present invention adopts following structure, and making advantage on the existing structure of the present invention has the advantage on the material again.
As shown in Figure 1; total is by a Battery pack 101; one Battery pack brace 102; a framework 106; one is sealed press strip 105; 103, two power brick management boxes 107 of 104, two pole protective sleeves of a top cover and 18 M5 hold-down screws 108 and voltage sample wire harness and temperature sensor and wire harness thereof are formed.
The structure of framework as shown in Figure 2, framework is to be made up of in order to the holders 204 of fixed connecting piece 201, four L shaped edge frame bars 202 of 2 section plates and four.Four edge frame bars 202 and two section plates 201 form box body in order to hold battery.One end of framework is opened a breach (203), puts into battery during in order to assembling.Pre-buried nut, more convenient and quicker when assembling like this in the holder in order to fixed connecting piece.Total is except pre-buried hold-down nut, and all the other all are the FRP materials.
