Abstract

Purpose

The study assesses the most significant architectural core technological system that converges into a Battery Electric Vehicle (BEV).

Design/methodology/approach

Conceptually grounded in the convergence phenomenon and utilizing the graph theory-based network construction approach, based on the Betweenness Centrality (BC) metric, core International Patent Classifications (IPCs) have been empirically identified. Based on these IPCs, the ownership structure of the patents was established through assignee analysis.

Findings

Analyzing the networks obtained at different IPC levels, we found that multiple technologies have converged in a BEV, from battery chemistry to electrical engineering and thermal management of electrical machines.

Research limitations/implications

The outcome of this work has led to the identification of BEV technologies, which can be further developed to assess the trends of technologies and associated gaps and aid technology management for the selection, acquisition, and exploitation of technology.

Practical implications

The outcome of this work will aid technology management practitioners in better planning the selection, acquisition, and exploitation of technologies associated with BEV.

Originality/value

The paper adds an evidence-based approach to the body of knowledge to identify the built-in technologies that produce a BEV.

通过专利看到电池电动汽车技术的融合

目的本研究评估了汇聚成电池电动汽车（BEV）的最重要的架构核心技术系统。设计/方法/方法从汇聚现象的概念出发，利用基于图论的网络构建方法，基于 "关联度中心性"（BC）指标，通过经验确定了核心国际专利分类（IPC）。研究结果通过分析在不同 IPC 层面上获得的网络，我们发现，从电池化学到电气工程和电机热管理，多种技术在 BEV 中融合。这项工作的成果将有助于技术管理从业人员更好地规划与 BEV 相关的技术的选择、获取和利用。
