Problems solved by technology

However, the current battery controller has a complex structure, unreasonable arrangement of circuit components, and large volume. In particular, the total height occupied by the battery controller in the battery packaging structure is relatively large, resulting in a low absolute storage capacity of the rechargeable battery.

Embodiment 1

[0218] Battery Example 1: a rechargeable battery with a lithium-ion battery in a steel case.

[0219] This application takes the implementation method of the rechargeable battery 100a as an example, and provides a structural method for the integrated system integration of the rechargeable battery 100a using the steel-cased lithium-ion battery 200a. This method is also applicable to the construction of the steel-cased lithium-ion battery. Different types of rechargeable batteries.

[0220] Such as figure 1 , figure 2 The shown steel-cased lithium-ion rechargeable battery 100a is composed of a steel-cased lithium-ion battery cell 200a and a battery controller 400a. The internal structure of the rechargeable battery 100a is as follows: image 3 As shown, the assembly relationship is as Figure 4 As shown, the structure of the steel shell lithium ion battery cell 200a is as follows Image 6 shown.

[0221] refer to figure 1 with figure 2 , the steel-cased lithium-ion rech...

Embodiment 2

[0260] Battery Example 2: a rechargeable battery with direct-sealed lithium-ion batteries.

[0261] refer to Figure 7 to Figure 12 , the present embodiment adopts the structural method of direct-sealed lithium-ion cells 200b to form an integrated system integration of the rechargeable battery 100b, and this method is applicable to various types of rechargeable batteries composed of direct-sealed lithium-ion cells.

[0262] To be precise, the direct-sealed lithium-ion battery cell 200b can be accurately called a lithium-ion battery cell after it is packaged by the battery case 110b and the battery controller 400b, but in this state its overall structure has constituted the rechargeable battery 100b . In order to unify the terminology with the steel-cased lithium-ion battery cell and the soft-packed lithium-ion battery cell, in this embodiment, the direct-sealed lithium-ion battery core 201b is inserted into the battery case 110b but the open end of the battery case 110b is ...

Embodiment 3

[0294] Battery Example 3: a rechargeable battery with a soft-packed lithium-ion battery.

[0295] This application adopts the structural method of the integrated system integration of the rechargeable battery 100c formed by the soft-packed lithium-ion battery cell 200c, and this implementation method is applicable to different types of rechargeable batteries.

[0296] Such as Figure 13 , Figure 14 The shown rechargeable battery 100c is composed of a soft pack lithium-ion cell 200c and a battery controller 400c; the internal structure of the rechargeable battery 100c is as follows Figure 15 As shown, the structural assembly relationship is as follows Figure 16 shown.

[0297] refer to Figure 15 with Figure 16 In this embodiment, the rechargeable battery 100c with a soft-packed lithium-ion battery includes: a soft-packed lithium-ion battery 200c and a battery controller 400c coaxially stacked at the end where the positive electrode of the soft-packed lithium-ion batte...

Abstract

The invention discloses a rechargeable battery and a battery controller, the rechargeable battery comprises a lithium ion cell and the battery controller, the battery controller comprises a circuit board and a positive electrode end cover, the circuit board comprises a first surface and a second surface which are oppositely arranged, and the first surface and the second surface are both provided with circuit components; the positive electrode end cover is made of a metal conductive material, is electrically connected with the circuit board and comprises a positive electrode end cover plate anda cap wall formed on the outer periphery of the positive electrode end cover plate, the positive electrode end cover plate and the cap wall form a cylindrical cap body with an opening in one end andan inner cavity, and the periphery of the opening of the cap body is in close contact with the first surface of the circuit board; and part or all of the circuit components on the first surface are packaged in the inner cavity of the cap body. By optimizing the structure of the battery controller, the axial height of the controller is reduced, and then the absolute storage energy and the volumetric specific energy of the rechargeable battery are improved.

Description

technical field [0001] The invention relates to the technical field of secondary batteries, in particular to a rechargeable battery and a battery controller applied to the rechargeable battery. Background technique [0002] The cylindrical primary battery standardized by GB / T 8897.2 (IEC 60086-2) has been widely used in the field of hand-held or portable electronic and electrical products. Due to the fact that primary batteries cannot be reused, and there are problems such as high battery cost and environmental pollution caused by waste batteries, the demand for secondary battery products that can replace GB / T 8897.2 (IEC 60086-2) standardized primary batteries is increasing in the consumer market. . [0003] In the field of rechargeable battery products compatible with GB / T 8897.2 (IEC 60086-2) standardized primary batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries and other products have been born successively, but these rechargeabl...
