Problems solved by technology

At present, the same style and size of the battery pack in the new energy market cannot be changed, and it cannot be well adapted to the upgrading of the market. The singleness of the style cannot meet the needs of the market and customers.
In the process of battery production and use, there are problems such as fire and explosion. In the production and use of electric vehicle batteries, they are only wrapped with PVC plastic parts, and the outer layer has no protection. When the battery is hit by fire and explosion, it cannot effectively protect the vehicle and User's personal safety
At the same time, the battery module cannot be vacuum isolated from the outside world, and it cannot effectively prevent water ingress, water leakage and other adverse phenomena in rainy days, reducing the service life of the battery

Embodiment 1

[0020] like image 3 As shown, 52 high-capacity batteries 10 are taken, each of which is 4 as a group, and two adjacent groups are arranged upside down and closely arranged to form a battery module 3. The positive and negative poles of the battery modules at both ends of the battery module 3 are respectively The positive and negative bus lines 6 are led out by single-sided nickel sheet 11 spot welding, and the positive and negative electrodes of the two adjacent cell groups in the middle are connected by double-sided nickel sheet 12. The silverfish with a size of 74mm×66mm×250mm is assembled according to PCAK A small battery module 3. A rectangular straight box body 1 with an overall size of 78mm×70mm×260mm and a concave square box cover 2 with a size of 75mm×67mm×10mm are made of metal materials. First, put the small battery module 3 assembled by PCAK into the box body 1 with a rectangular straight structure, lead the positive and negative bus lines 6 through the positive an...

Embodiment 2

[0022] like Figure 4 As shown, 52 high-capacity batteries 10 are taken, and each group of 4 is divided into 13 groups. Every 5 groups are connected in series through unilateral nickel sheets 11 to form a whole row, and the other 3 groups are connected in series to form a half row, and two full rows The electrodes of the batteries are overlapped upside down, and then the half-column is inverted and overlapped with the electrodes of the overlapped batteries. The negative electrode of the first cell group and the positive electrode of the last cell group lead out the positive and negative bus 6 through the single-sided nickel sheet 11; the series-parallel folding small battery module 3 with the overall size of 74mm×55mm×325mm assembled by PCAK For example, metal materials are used to make a rectangular straight box body 1 with an overall size of 78mm×60mm×335mm and a concave square box cover 2 with a size of 75mm×57mm×10mm. First, put the small battery module 3 assembled by PCA...

Embodiment 3

[0024] like Figure 5 As shown, 52 high-capacity batteries 10 are taken, and each group of 4 is divided into 13 groups, which are connected in series into 7 groups and 6 groups by unilateral nickel sheets 11, and then the two rows of cells are connected in series. The electrodes are upside down and overlapped, and the positive and negative poles of the two adjacent cell groups at the ends are connected through a double-sided nickel sheet 12, and the negative electrode of the first group of cells in the first column and the positive electrode of the last group of cells in the last column pass through a single-sided nickel sheet (11) Leading out the positive and negative bus 6, taking the series-parallel foldable small battery module 3 with an overall size of 74mm×37mm×455mm assembled by PCAK as an example, a metal material is used to make a battery module with an overall size of 78mm×40mm×465mm A rectangular straight box body 1 and a concave square box cover 2 with a size of 75...

Abstract

The invention discloses a small battery pack with a protecting box and solves the problems that in the prior art, batteries are single in style and are flammable and combustible and the like. The small battery pack is characterized in that a box body (1) is of a rectangular straight barrel structure, four prisms are arc-shaped edges (4), and round holes (5) are formed in the edge of the opening inthe top; a box cover (2) is of a concave square structure, two threading holes (9) for leading positive and negative buses of a battery module out are formed in a cover bottom plate, threaded holes (7) are formed in the side walls around, corresponding to the round holes (5) formed in the edge of the opening in the top, and an embedded fixed edge (8) is arranged at the outer edge of the top; thebattery module (3) is assembled by a high capacity battery cell (10), a single-sided nickel chip (11) and a double-sided nickel chip (12) according to a PCAK program. The small battery pack has the advantages of being compact in structure, simple to manufacture, safe to use, adjustable in size, various in style, attractive in appearance and the like, and can be widely applied to various types of electric vehicles.

Description

Technical field: [0001] The invention belongs to the field of new energy battery accessories, and in particular relates to a small battery pack with a protective box. Background technique: [0002] The 21st century is an era with the theme of new energy, and new energy power batteries also show their unstoppable development momentum in response to the needs of the times. At present, in the new energy market, the battery pack of the same style is single in size, cannot be changed in production, and cannot well adapt to the upgrading of the market. The singleness of the style cannot meet the needs of the market and customers. In the process of battery production and use, there are problems such as fire and explosion. In the production and use of electric vehicle batteries, they are only wrapped with PVC plastic parts, and the outer layer has no protection. When the battery is hit by fire and explosion, it cannot effectively protect the vehicle and User's personal safety. At ...
