蓄电池SOH估算方法研究综述

Review of SOH Estimation Method for Battery

蓄电池运行状态是否正常,直接影响着应用领域中各种设备的正常、可靠和安全运行。在无人值守现场、电子商务中心、银行等关键公共场合,蓄电池就显得更为重要。电池健康状态用于定量描述电池当前偏离额定指标的程度,是蓄电池状态监测的重要指标。由于蓄电池结构的复杂性,电池健康状态无法直接测量读数,只能通过外特性估算。重点阐述了近年来蓄电池健康状态的估算方法。

The operating status of the battery has a direct impact on the reliable and safe operation of various devices.In the unattended scene,e-commerce center,banks and other key public places,the battery looks to be more important.The state of its health is used to quantitatively describe the current deviation of its index value and it is an important indication of the battery status monitoring.Due to the complexity of the battery structure,this paper can’t directly measure the state of health reading and only uses its external characteristics to estimate its status.It also summarizes the battery SOH estimation methods in recent years.
