锂离子电池特性研究

为了提高锂离子电池组的安全性和使用寿命,需要对电池组进行有效的控制和管理。电池荷电状态（SOC）是电池管理系统中最重要的参数之一,是系统中其他功能的基础。因此,电池SOC实时、准确的估计有着重要的现实意义。实现电池SOC实时、准确的估计的基础是建立精确的电池模型。针对锂离子电池的几个主要特性进行了相关的研究和实验验证,为电池模型的建立提供了依据。

The lithium-ion battery characteristics research

In order to improve the lithium-ion battery safety and service life, the battery pack needs to effectively control and manage. Battery state of charge （SOC） battery management system is not only one of the most important parameters of the system, but also the basis for other functions. Therefore, the battery SOC real time, accurate estimates has important practical significance. Battery SOC basis to achieve real-time and accurate estimate is to establish accurate battery models. This paper researched several key characteristics of lithium-ion batteries, made some experimental verification for that, and provided basis the for establishment of the battery model.
