Solution Overview

Problem

The complexity of connecting busbars to pole components in battery configurations hinders efficient grouping and usage performance due to limited configuration positions.

Innovation Solution

The pole component is positioned on the outer side of the battery casing, with its projection extending beyond the casing's surface range, facilitating easier electrical connections with busbars and improving grouping efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the pole component is positioned inside the battery casing, then the battery structure is compact, but the connection between busbar and pole component becomes complicated and difficult

Engineering Contradiction:
Improveconnection easeVSAvoidconnection complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The pole component is extracted from the interior of the battery casing and positioned at least partially outside the casing. This extraction allows the busbar to connect to the pole component more easily without navigating through the confined interior space, thereby simplifying the connection process while maintaining a compact battery structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The pole component is repositioned from a two-dimensional interior plane to a three-dimensional configuration that extends outside the battery casing. This dimensional change creates additional spatial freedom for busbar connection, allowing the busbar to approach the pole component from multiple directions and simplifying the overall connection geometry.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the pole component is positioned on the outer side of the battery casing, then the busbar connection is facilitated, but the battery structure becomes more complex

Engineering Contradiction:
Improvegrouping efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The pole component serves dual functions: it acts as the electrical terminal for the battery while simultaneously serving as a connection interface for the busbar. By positioning the pole component outside the casing, it fulfills both electrical and mechanical connection roles, thereby improving grouping efficiency without significantly increasing overall structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If the pole component is positioned inside the battery casing, then the battery structure is simple, but the grouping efficiency is reduced

Engineering Contradiction:
Improvegrouping efficiencyVSAvoidconnection difficulty
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The pole component is pre-positioned outside the battery casing during the battery assembly process. This preliminary positioning ensures that when multiple batteries are grouped together, the pole components are already in optimal positions for busbar connection, thereby improving grouping efficiency and reducing the difficulty of subsequent connection operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to the technical field of batteries and provides a battery and a battery apparatus. The battery includes a battery casing and a pole component. The pole component is disposed on a first surface of the battery casing, at least part of the pole component is located on an outer side of the battery casing, and a part of an orthographic projection of the pole component toward a plane where the first surface is at is located outside a range where the first surface is at, so that an electrical connection between a busbar and the pole component can be facilitated, and the difficulty of connecting the busbar and the pole component can be reduced, thereby improving the grouping efficiency of the battery, so as to improve the usage performance of the battery.
